Cell Proliferation
All of the processes involved in increasing CELL NUMBER including CELL DIVISION.
Cell Division
The fission of a CELL. It includes CYTOKINESIS, when the CYTOPLASM of a cell is divided, and CELL NUCLEUS DIVISION.
Cells, Cultured
Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.
Signal Transduction
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
Cell Line, Tumor
A cell line derived from cultured tumor cells.
Apoptosis
One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
Cell Cycle
The complex series of phenomena, occurring between the end of one CELL DIVISION and the end of the next, by which cellular material is duplicated and then divided between two daughter cells. The cell cycle includes INTERPHASE, which includes G0 PHASE; G1 PHASE; S PHASE; and G2 PHASE, and CELL DIVISION PHASE.
Cell Differentiation
Progressive restriction of the developmental potential and increasing specialization of function that leads to the formation of specialized cells, tissues, and organs.
Bromodeoxyuridine
A nucleoside that substitutes for thymidine in DNA and thus acts as an antimetabolite. It causes breaks in chromosomes and has been proposed as an antiviral and antineoplastic agent. It has been given orphan drug status for use in the treatment of primary brain tumors.
RNA, Messenger
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.
Cell Movement
The movement of cells from one location to another. Distinguish from CYTOKINESIS which is the process of dividing the CYTOPLASM of a cell.
Cell Survival
The span of viability of a cell characterized by the capacity to perform certain functions such as metabolism, growth, reproduction, some form of responsiveness, and adaptability.

Proliferating Cell Nuclear Antigen
Nuclear antigen with a role in DNA synthesis, DNA repair, and cell cycle progression. PCNA is required for the coordinated synthesis of both leading and lagging strands at the replication fork during DNA replication. PCNA expression correlates with the proliferation activity of several malignant and non-malignant cell types.
Lymphocyte Activation
Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.
Phosphorylation
The introduction of a phosphoryl group into a compound through the formation of an ester bond between the compound and a phosphorus moiety.

Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control of gene action in neoplastic tissue.
RNA, Small Interfering
Small double-stranded, non-protein coding RNAs (21-31 nucleotides) involved in GENE SILENCING functions, especially RNA INTERFERENCE (RNAi). Endogenously, siRNAs are generated from dsRNAs (RNA, DOUBLE-STRANDED) by the same ribonuclease, Dicer, that generates miRNAs (MICRORNAS). The perfect match of the siRNAs' antisense strand to their target RNAs mediates RNAi by siRNA-guided RNA cleavage. siRNAs fall into different classes including trans-acting siRNA (tasiRNA), repeat-associated RNA (rasiRNA), small-scan RNA (scnRNA), and Piwi protein-interacting RNA (piRNA) and have different specific gene silencing functions.

Epithelial Cells
Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
Flow Cytometry
Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.
Dose-Response Relationship, Drug
The relationship between the dose of an administered drug and the response of the organism to the drug.
Mice, Knockout
Strains of mice in which certain GENES of their GENOMES have been disrupted, or "knocked-out". To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.

T-Lymphocytes
Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes.

Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors.

Emerging targets: molecular mechanisms of cell contact-mediated growth control. (1/45748)

Contact inhibition of cell proliferation evokes a unique cellular program of growth arrest compared with stress, age, or other physical constraints. The last decade of research on genes activated by cell-cell contact has uncovered features of transmembrane signaling, cytoskeletal reorganization, and transcriptional control that initiate and maintain a quiescent phenotype. This review will focus on mechanisms controlling contact inhibition of cell proliferation, highlighting specific gene expression responses that are activated by cell-cell contact. Although a temporal framework for imposition of these mechanisms has not yet been well described, contact inhibition of cell proliferation clearly requires their coordinated function. Novel targets for intervention in proliferative disorders are emerging from these studies.  (+info)

Cell cycle dysregulation in oral cancer. (2/45748)

The dysregulation of the molecular events governing cell cycle control is emerging as a central theme of oral carcinogenesis. Regulatory pathways responding to extracellular signaling or intracellular stress and DNA damage converge on the cell cycle apparatus. Abrogation of mitogenic and anti-mitogenic response regulatory proteins, such as the retinoblastoma tumor suppressor protein (pRB), cyclin D1, cyclin-dependent kinase (CDK) 6, and CDK inhibitors (p21(WAF1/CIP1), p27(KIP1), and p16(INK4a)), occur frequently in human oral cancers. Cellular responses to metabolic stress or genomic damage through p53 and related pathways that block cell cycle progression are also altered during oral carcinogenesis. In addition, new pathways and cell cycle regulatory proteins, such as p12(DOC-1), are being discovered. The multistep process of oral carcinogenesis likely involves functional alteration of cell cycle regulatory members combined with escape from cellular senescence and apoptotic signaling pathways. Detailing the molecular alterations and understanding the functional consequences of the dysregulation of the cell cycle apparatus in the malignant oral keratinocyte will uncover novel diagnostic and therapeutic approaches.  (+info)

Small-molecule modulators of Hedgehog signaling: identification and characterization of Smoothened agonists and antagonists. (3/45748)

BACKGROUND: The Hedgehog (Hh) signaling pathway is vital to animal development as it mediates the differentiation of multiple cell types during embryogenesis. In adults, Hh signaling can be activated to facilitate tissue maintenance and repair. Moreover, stimulation of the Hh pathway has shown therapeutic efficacy in models of neuropathy. The underlying mechanisms of Hh signal transduction remain obscure, however: little is known about the communication between the pathway suppressor Patched (Ptc), a multipass transmembrane protein that directly binds Hh, and the pathway activator Smoothened (Smo), a protein that is related to G-protein-coupled receptors and is capable of constitutive activation in the absence of Ptc. RESULTS: We have identified and characterized a synthetic non-peptidyl small molecule, Hh-Ag, that acts as an agonist of the Hh pathway. This Hh agonist promotes cell-type-specific proliferation and concentration-dependent differentiation in vitro, while in utero it rescues aspects of the Hh-signaling defect in Sonic hedgehog-null, but not Smo-null, mouse embryos. Biochemical studies with Hh-Ag, the Hh-signaling antagonist cyclopamine, and a novel Hh-signaling inhibitor Cur61414, reveal that the action of all these compounds is independent of Hh-protein ligand and of the Hh receptor Ptc, as each binds directly to Smo. CONCLUSIONS: Smo can have its activity modulated directly by synthetic small molecules. These studies raise the possibility that Hh signaling may be regulated by endogenous small molecules in vivo and provide potent compounds with which to test the therapeutic value of activating the Hh-signaling pathway in the treatment of traumatic and chronic degenerative conditions.  (+info)

Gleevec (STI-571) inhibits lung cancer cell growth (A549) and potentiates the cisplatin effect in vitro. (4/45748)

BACKGROUND: Gleevec (aka STI571, Imatinib) is a recently FDA approved anti-tumor drug for chronic myelogenous leukemia. Gleevec binds specifically to BCR-ABL tyrosine kinase and inhibit the tyrosine kinase activity. It cross-reacts with another two important membrane tyrosine kinase receptors, c-kit and PDGF receptors. We sought to investigate if Gleevec has a potential role in treatment of non-small cell lung cancer. RESULTS: We have shown that Gleevec alone can inhibit the A549 lung cancer cell growth in dose-dependent manner, and the optimal concentration of Gleevec inhibition of A549 cell growth is at the range of 2-3 microM (IC50). We have also shown that A549 cells are resistant to cisplatin treatment (IC50 64 microM). Addition of Gleevec to the A549 cells treated with cisplatin resulted in a synergistic cell killing effect, suggesting that Gleevec can potentiate the effect of cisplatin on A549 cells. We also showed that the A549 lung cancer cells expresses the platelet derived growth factor receptor alpha, and the inhibitory effects of Gleevec on A549 cells is likely mediated through inhibition of PDGFR alpha phosphorylation. We further tested 33 lung cancer patients' tumor specimens to see the frequency of PDGFR-alpha expression by tissue micro-arrays and immunohistochemistry. We found that 16 of the 18 squamous carcinomas (89%), 11 of the 11 adenocarcinomas (100%), and 4 of the 4 small cell lung cancers (100%) expressed PDGFR-alpha. CONCLUSION: These results suggest a potential role of Gleevec as adjuvant therapeutic agent for treatment of non-small cell lung cancer.  (+info)

Hepatocarcinogenic potential of the glucocorticoid antagonist RU486 in B6C3F1 mice: effect on apoptosis, expression of oncogenes and the tumor suppressor gene p53. (5/45748)

BACKGROUND: Glucocorticoids inhibit hepatocellular proliferation and modulate the expression of oncogenes and tumor suppressor genes via mechanisms involving the glucocorticoid receptor. Glucocorticoids also produce a receptor-mediated inhibitory effect on both basal and hormone-stimulated expression of a newly discovered family of molecules important for shutting off cytokine action. We therefore hypothesized that inhibiting glucocorticoid receptors may disturb hepatocellular growth and apoptosis. Consequently, we investigated the effect of RU486, a potent antagonist of the glucocorticoid receptor, on basal levels of hepatocellular proliferation and apoptosis in male B6C3F1 mice. Furthermore, we evaluated the effect of this compound on cellular genes involved in the regulation of these important processes. RESULTS: Data show that treatment of male B6F3C1 mice with RU486 (2 mg/kg/d, ip) for 7 days dramatically inhibited liver cell proliferation by about 45% and programmed hepatocellular death by approximately 66%. RU 486 also significantly increased hepatic expression of the oncogenes mdm2 and JunB, while reducing that of the tumor suppressor gene p53. CONCLUSION: Exposure to RU486 may ultimately enhance the susceptibility of the liver to cancer risk by diminishing its ability to purge itself of pre-cancerous cells via apoptosis. This effect may be mediated through increases in the hepatic expression of the oncogene mdm2, coupled with decreases in that of the tumor suppressor gene p53. The decrease in hepatocellular proliferation caused by RU 486 may be related to effects other than its anti-glucocorticoid activity.  (+info)

Recombinant human interleukin-10 inhibits proliferation of vascular smooth muscle cells stimulated by advanced glycation end products and neointima hyperplasia after carotid injury in the rat. (6/45748)

The purposes of this study was to determine the effects of recombinant human interleukin-10 (rhIL-10) on proliferation of vascular smooth muscle cells (VSMCs) stimulated by advanced glycation end products (AGE) and neointima hyperplasia after rat carotid arterial injury. Rat aortic VSMCs were cultured and treated with rhIL-10 or AGE respectively, and then co-treated with rhIL-10 and AGE. Proliferation of VSMCs was quantified by colormetric assay. Cell cycle analysis was performed by flow cytomertry. Sprague-Dawley rats were treated with recombinant human IL-10 (rhIL-10) for 3 d after carotid arteries injury. The ratio of neointima to media area at the site of arterial injury was measured 28 d after balloon injury. The p44/42 MAPK activity was evaluated by the immunoblotting technique using anti-p44/42 phospho-MAPK antibody. Compared to control, AGE stimulated VSMCs proliferation. rhIL-10 alone had no effect on VSMCs growth. With AGE stimulation, rhIL-10, at dose as low as 10 ng/ml, inhibited VSMCs growth (P<0.05). The cell number in G(0)/G(1) phase of AGE and rhIL-10 co-treatment group was higher than that of AGE treatment alone (P<0.01) by flow cytometry analysis. Compared with the control group of neointima hyperplasia in rats, the ratio of neointima to media area of recombinant human IL-10 group was reduced by 45% (P<0.01). The p44/42 MAPK activity was significantly enhanced by AGE. The AGE effects were opposed by rhIL-10. The anti-inflammatory cytokine rhIL-10 inhibits AGE-induced VSMCs proliferation. Recombinant human IL-10 also inhibited neointima hyperplasia after carotid artery injury in rats. The results suggest the possibility that recombinant human IL-10, as a potential therapeutic approach, prevents neointimal hyperplasia.  (+info)

The effects of inhibiting P18(INK4C) expression on the invasion of gastric adenocarcinoma cell line. (7/45748)

Using cDNA microarray with double dots of 4096 human genes, P18(INK4C), a member of CKI, was found down-regulated in a gastric adenocarcinoma metastatic cell line (RF-48), compared with the corresponding primary cancer cell line (RF-1), which implied that P18(INK4C) might be involved in cell invasion and metastatic progression of human gastric adenocarcinoma. Antisense RNA expression plasmid was applied to inhibit P18(INK4C) expression to study the effect of decreased P18(INK4C) expression on cell migration, invasion and proliferation ability and cell cycle of RF-1. Results showed that inhibition of P18(INK4C) expression could obviously enhance cell invasion ability of RF-1, but had little effect on its cell cycle and cell migration and proliferation ability. These results implied that P18(INK4C) might play a pivotal role in regulating cell invasion, rather than regulating cell cycle and proliferation in the progression of human gastric adenocarcinoma as expected before.  (+info)

Comparative proteomic analysis of proliferating and functionally differentiated mammary epithelial cells. (8/45748)

Proliferation and differentiation of mammary epithelial cells are governed by hormonal stimuli, cell-cell, and cell-matrix interactions. Terminal differentiation of mammary epithelial cells depends upon the action of the lactogenic hormones, insulin, glucocorticoids, and prolactin that enable them to synthesize and secrete milk proteins. These differentiated cells are polarized and carry out vectorial transport of milk constituents across the apical plasma membrane. To gain additional insights into the mechanisms governing differentiation of mammary epithelial cells, we identified proteins whose expression distinguishes proliferating from differentiated mammary epithelial cells. For this purpose we made use of the HC11 mammary epithelial line, which is capable of differentiation in response to lactogenic hormones. Using two-dimensional gel electrophoresis and mass spectrometry, we found about 60 proteins whose expression levels changed in between these two differentiation states. Bioinformatic analysis revealed differential expression of cytoskeletal components, molecular chaperones and regulators of protein folding and stability, calcium-binding proteins, and components of RNA-processing pathways. The actin cytoskeleton is asymmetrically distributed in differentiated epithelial cells, and the identification of proteins involved in mRNA binding and localization suggests that asymmetry might in part be achieved by controlling cellular localization of mRNAs. The proteins identified provide insights into the differentiation of mammary epithelial cells and the regulation of this process.  (+info)

BrdU Chemiluminescent Cell Proliferation Assay Kit - Exalpha Biologicals inc.BrdU Chemiluminescent Cell Proliferation Assay Kit - Exalpha Biologicals inc.
The BrdU Chemiluminescent Cell Proliferation Assay Kit is a non-isotopic enzyme immunoassay for the quantification of DNA synthesis and cell proliferation. Evaluation of cell cycle progression is essential for investigations in many scientific fields. Measurement of [3H] thymidine incorporation as cells enter S phase has long been the traditional method for the detection of cell proliferation. Subsequent quantification of [3H] thymidine is performed by scintillation counting or autoradiography. This technology is slow, labor intensive and has several limitations including the handling and disposal of radioisotopes and the necessity of expensive equipment. A well-established alternative to [3H] thymidine uptake has been demonstrated by numerous investigators. In these methods bromodeoxyuridine (BrdU), a thymidine analog, replaces [3H] thymidine. BrdU is incorporated into newly synthesized DNA strands of actively proliferating cells. Following partial denaturation of double stranded DNA, BrdU is ...

We have shown that 4-1BB in myeloid cells, particularly in APCs, negatively regulates peripheral T cell responses in vivo. Thus, adoptively transferred CD4+ and CD8+ T cells showed the enhanced T cell proliferation in tumor-bearing RAG2−/−4-1BB−/− mice, and DCs and IL-15 were primarily responsible for this enhanced T cell proliferation. However, isolated 4-1BB+/+ and 4-1BB−/− DCs made comparable levels of IL-15, and individual 4-1BB−/− DCs induced T cell responses in vivo less efficiently than 4-1BB+/+ DCs. Therefore, we concluded that 4-1BB deficiency in myeloid cells in vivo induces the enhanced proliferation of peripheral T cells by promoting the accumulation of DCs in secondary lymphoid organs.. Although enhanced T cell responses were first reported when 4-1BB−/− mice were generated more than a decade ago (29), the underlying mechanism was not understood. Other studies have also pointed to a negative regulatory function of 4-1BB in modulating T cell responses. Thus, ...

NSCLC is the most prevalent cancer types and has highest mortality rate in China [1]; however, the progression mechanisms of NSCLC have largely remained elusive. Ample evidence indicates a crucial role for miRNAs in human cancer [21], especially the miRNAs participate in the initiation, promotion, and progression of NSCLC. For instance, miR-21 promotes growth and invasion of NSCLC [22]. In addition, miR-494, miR-101, miR-1254, miR-574-5p, miR-143 and miR-181a were demonstrated to be involved in NSCLC [23-25]. In the present study, we certified that miR-361-3p was frequently down-regulated in NSCLC, and first found that the reduced miR-361-3p expression was closely related to advanced stage and lymph node metastasis of NSCLC. Furthermore, we demonstrated that overexpression of miR-361-3p could suppress NSCLC cell proliferation, migration and invasion in vitro and in vivo. The versatile functions of miR-361-3p in tumor cell proliferation, migration and invasion suggest its potential application as ...

Breast cancer is one of the most lethal types of cancer in women worldwide due to the late stage detection and resistance to traditional chemotherapy. The human epidermal growth factor receptor 2 (HER2) is considered as a validated target in breast cancer therapy. Even though a substantial effort has been made to develop HER2 inhibitors, only lapatinib has been approved by the U.S. Food and Drug Administration (FDA). Side effects were observed in a majority of the patients within one year of treatment initiation. Here, we took advantage of bioinformatics tools to identify novel effective HER2 inhibitors. The structure-based virtual screening combined with ADMET (absorption, distribution, metabolism, excretion and toxicity) prediction was explored. In total, 11,247 natural compounds were screened. The top hits were evaluated by an in vitro HER2 kinase inhibition assay. The cell proliferation inhibition effect of identified inhibitors was evaluated in HER2-overexpressing SKBR3 and BT474 cell lines. We

shRNA against CD44 inhibits cell proliferation, invasion and migration, and promotes apoptosis of colon carcinoma cellsshRNA against CD44 inhibits cell proliferation, invasion and migration, and promotes apoptosis of colon carcinoma cells
CD44 is a causal factor for tumor invasion, metastasis and acquisition of resistance to apoptosis. CD44 knockdown using inducible short hairpin RNA (shRNA) significantly reduces cell growth and invasion. Short hairpin RNA against CD44 and pGFP-V-RS-vector was used for knockdown of CD44 expression in SW620 colon cancer cells. Cell growth, invasion and migration assay, immunofluorescence for β-catenin expression and western blotting for Wnt signaling molecules were analyzed. Cell cycle analysis and western blot analysis for apoptotic molecules were evaluated. Short hairpin RNA against CD44 reduced the expression of CD44. Cell proliferation, migration and invasion were markedly inhibited and apoptosis was increased in shRNA CD44-transfected cells. Knockdown of CD44 decreased the phosphorylation of PDK1, Akt and GSK3β, and β-catenin levels. Decreased phosphorylated Akt led to an increase in phosphorylated FoxO1 and induced cell cycle arrest in the G0-G1 phase and a decrease in the S phase. The ...

: Migration and invasion enhancer 1 (MIEN1) is a membrane-anchored protein and exists in various cancerous tissues. However, the roles of MIEN1 in prostate cancer have not yet been clearly addressed. We determined the expression, biological functions, and regulatory mechanisms of MIEN1 in the prostate. The results of immunohistochemical analysis indicated that MIEN1 was expressed specifically in epithelial cells and significantly higher in adenocarcinoma as compared to in normal tissues. MIEN1 enhanced in vitro cell proliferation, invasion, and in vivo tumorigenesis. Meanwhile, MIEN1 attenuated cisplatin-induced apoptosis in PC-3 cells. Overexpression of NF-ĸB-inducing kinase (NIK) enhanced MIEN1 expression, while overexpression of NF-ĸB inhibitor α (IĸBα) blocked MIEN1 expression in PC-3 cells. In prostate carcinoma cells, MIEN1 provoked Akt phosphorylation; moreover, MIEN1 downregulated N-myc downstream regulated 1 (NDRG1) but upregulated interleukin-6 (IL-6) gene expression. MK2206, an

Introduction The difficulty in re-growing and mineralizing new bone after severe fracture can result in loss of ambulation or limb. Here we describe the sequential roles of FGF-2 in inducing gene expression, cell growth and BMP-2 in gene expression and mineralization of bone. Materials and methods The regulation of gene expression was determined using real-time RTPCR (qRTPCR) and cell proliferation was measured by thymidine incorporation or fluorescent analysis of DNA content in MC3T3E1 osteoblast-like cells. Photomicroscopy was used to identify newly mineralized tissue and fluorescence was used to quantify mineralization. Results Fibroblast growth factor-2 (FGF-2) had the greatest ability to induce proliferation after 24 hours of treatment when compared to transforming growth factor beta (TGFβ, insulin-like growth factor-1 (IGF-1), bone morphogenic protein (BMP-2), platelet derived growth factor (PDGF) or prostaglandin E2 (PGE2). We found that FGF-2 caused the most significant induction of ...

News about Cell-Based AssaysNews about Cell-Based Assays
Cell proliferation assays are performed by four decades in cancer research to test the anti-proliferative activity of natural products and synthetic compounds in in vitro tumor models such as cell lines. However, current parameters used to quantify growth inhibition lead to a misinterpretation of results based on the exponential, and not linear, proliferation of cells in culture. We recently published in Journal of Cellular Physiology the development and experimental validation of a new parameter for the analysis of growth inhibition in proliferation assays, termed relative doubling capacity, that can be used to properly quantify the anti-proliferative activity of tested compounds in cell cultures and compare drug efficacy between distinct cell models. ...

Identification of new p53 target microRNAs by bioinformatics and functional analysis | BMC Cancer | Full TextIdentification of new p53 target microRNAs by bioinformatics and functional analysis | BMC Cancer | Full Text
The master regulator p53 is a prominent tumor suppressor gene, functioning in the cell as a tetrameric (dimer of dimers) sequence-specific transcription factor, able to bind to two copies of a decameric sequence with the RRRCWWGYYY consensus (where R stands for a purine, W for A/T and Y for a pyrimidine) representing the so called p53-response element (p53-RE) [1]. p53 is known to be inducible in response to a large number of cellular stress signals that, besides genotoxic stress, include carbon and oxygen deficiencies, perturbations of the translation apparatus, excessive proliferation signals, alteration in microtubule dynamics [2, 3]. There are ,100 established p53 targets genes that link p53 to cell cycle arrest, apoptosis, DNA repair and inhibition of angiogenesis [3-6]. More recently, p53 was demonstrated to modulate the expression of genes able to modify glucose as well as lipid metabolism, induction of autophagy, immune responses and cell motility [7-11]..

To determine the effect of protein treatments in cell proliferation, MDA-MB-231 breast cancer cells were first injected into the mammary fat pad of nude mice, and when tumors grew to 10 mm in diameter, mice were treated once only with purified Endo (20 mg/kg), CD (40 mg/kg), or EndoCD (60 mg/kg) proteins plus 500 mg/kg 5-FC, a clinically sufficient dose of 5-FU (15 mg/kg; 1× 5-FU), or 10 times the clinically sufficient dose (150 mg/kg; 10× 5-FU). The choice of 20 mg/kg Endo was based on a previous preclinical study (15) and is also within the dose tested in the phase I clinical trial (ref. 18; 15-600 mg/m2 in human is equivalent to 4.8-194.4 mg/kg in mouse; ref. 30). Tumors were harvested from mice 48 hours after treatment and labeled with bromodeoxyuridine (BrdU) antibody for in vivo BrdU incorporation analysis.

Aging | Sirt1-inducible deacetylation of p21 promotes cardiomyocyte proliferation - Full Text
Full Text - Inducing cardiomyocyte proliferation is a hopeful approach for cardiac regeneration following myocardial infarction. Previous studies have shown that p21 inhibits the cardiomyocyte proliferation and cardiac regeneration. Deacetylation of p21 by Sirt1 deacetylase may reduce p21 abundance and remove p21-induced cell cycle arrest. However, whether p21 deacetylation and Sirt1 deacetylate control cardiomyocyte proliferation is unclear. Here, we show that acetylation of p21 induces cardiomyocyte proliferation arrest, whereas blocking the acetylation of p21 increases cardiomyocyte proliferation. P21 can be acetylated by Sirt1, and Sirt1 activate p21 ubiquitination through deacetylation. Additionally, overexpression of Sirt1 induces EdU-, pH3-, and Aurora B-positive cardiomyocytes in neonatal and adult mice. In contrast, depletion of Sirt1 reduces cardiomyocyte proliferation in vitro and in vivo. Moreover, Sirt1 protects cardiac function, reduces cardiac remodeling, inhibits

The functional integrity of the intestinal epithelial barrier relies on tight coordination of cell proliferation and migration, with failure to regulate these processes resulting in disease. It is not known whether cell proliferation is sufficient to drive epithelial cell migration during homoeostatic turnover of the epithelium. Nor is it known precisely how villus cell migration is affected when proliferation is perturbed. Some reports suggest that proliferation and migration may not be related while other studies support a direct relationship. We used established cell-tracking methods based on thymine analog cell labeling and developed tailored mathematical models to quantify cell proliferation and migration under normal conditions and when proliferation is reduced and when it is temporarily halted. We found that epithelial cell migration velocities along the villi are coupled to cell proliferation rates within the crypts in all conditions. Furthermore, halting and resuming proliferation ...

We have previously demonstrated, that 15 days after female rats pace the sexual interaction, there is an increase in the number of new cells that reach the granular cell layer (GrL) of the accessory olfactory bulb (AOB). The aim of the present study was to evaluate, if the first sexual experience in the female rat increases cell proliferation in the subventricular zone (SVZ) and the rostral migratory stream (RMS). We also tested if this behavior promotes the survival of the new cells that integrate into the main olfactory bulb (MOB) and AOB 45 days after the behavioral test. Sexually, naive female rats were injected with the DNA synthesis marker 5′-bromo-2′-deoxyuridine (BrdU) on the day of the behavioral test. They were randomly divided into the following groups: Female rats placed alone in the mating cage (1); Females exposed to amyl acetate odor [banana scent, (2)]; Females that could see, hear, and smell the male but physical contact was not possible [exposed to male, (3)]; Female rats that

Markers of crypt cell proliferation are frequently employed in studies of the impact of genetic and exogenous factors on human colonic physiology. Human studies often rely on the assessment of tissue acquired at endoscopy. Modulation of cell proliferation by bowel preparation with oral laxatives may confound the findings of such studies, but there is little data on the impact of commonly used bowel preparations on markers of cell proliferation. Crypt length, crypt cellularity and crypt cell proliferation were assessed in biopsies acquired after preparation with either Klean-Prep or Picolax. Crypt cell proliferation was assessed by whole-mount mitotic figure count, and by two different immunohistochemical (IHC) labelling methods (Ki-67 and pHH3). Subsequent biopsies were obtained from the same patients without bowel preparation and similarly assessed. Parameters were compared between groups using analysis of variance and paired t-tests. There were significant differences in labelling indices (LI) between

Mesothelin (MSLN) overexpression in pancreatic cancer (PC) leads to enhanced cell survival/proliferation and tumor progression. After screening for a number of growth factors/cytokines, we found that the MSLN expression correlated closely with interleukin (IL)-6 in human PC specimens and cell lines. Stably overexpressing MSLN in different PC cell lines (MIA-MSLN and Panc1-MSLN) led to higher IL-6 production. Silencing MSLN by small interfering RNA (siRNA) significantly reduced IL-6 levels. Blocking the observed constitutive activation of nuclear factor-kappaB (NF-κB) with IKK inhibitor wedelolactone in MIA-MSLN cells also reduced IL-6. Silencing IL-6 by siRNA reduced cell proliferation, cell cycle progression and induced apoptosis with significant decrease of c-myc/bcl-2. Interestingly, recombinant IL-6-induced proliferation of MIA-MSLN cells but not MIA-V cells. Although messenger RNA/protein levels of IL-6R did not vary, soluble IL-6R (sIL-6R) was significantly elevated in MIA-MSLN and was ...

Without LPS stimulation, the proliferation activity of tumor cells increased during 12 h. The cell proliferation significantly changed by LPS stimulation, and the maximum absorbance value at 429 nm was present after 6 h, with a proliferation rate of approximately 137.1% compared to cells without stimulation (Figure 2AC2B). To investigate the effect of TLR4 signal block on cell proliferation, the TLR4 inhibitor TAK-242 was used. The LPS-stimulated increase in the proliferation of tumor cells was significantly reduced with TAK-242 pretreatment, whereas no significant change was observed in cells treated with TAK-242 alone (Figure ?(Figure2C).2C).

PC cell-derived growth factor (PCDGF), also called epithelin/granulin precursor (GEP), is an 88-kDa secreted glycoprotein with the ability to stimulate cell proliferation in an autocrine fashion. In addition, some studies indicated that PCDGF participated in invasion, metastasis and survival of cancer cells by regulating cell migration, adhesion and proliferation. Yet the effects of PCDGF on proliferation and invasion of ovarian cancer cells in vitro and the mechanisms by which PCDGF mediates biological behaviors of ovarian cancer have rarely been reported. In the present study we investigated whether and how PCDGF/GEP mediated cell proliferation and invasion in ovarian cancer. PCDGF/GEP expression level in three human ovarian cancer cell lines of different invasion potential were detected by RT-PCR and western blot.

Regulation of PMP22 mRNA by G3BP1 affects cell proliferation in breast cancer cells | Molecular Cancer | Full TextRegulation of PMP22 mRNA by G3BP1 affects cell proliferation in breast cancer cells | Molecular Cancer | Full Text
Regulation of mRNAs is one way to control protein levels and thereby important cellular processes such as growth, invasion and apoptosis. G3BPs constitute a family of mRNA-binding proteins, shown to be overexpressed in several cancer types, including breast, colon and pancreas cancer. G3BP has been reported to both stabilize and induce degradation of specific mRNAs. Here, we show that G3BP1, but not G3BP2, supports proliferation of several breast cancer cell lines. Global gene expression analyses of G3BP1- and G3BP2-depleted cells indicate that primarily G3BP1, and much less G3BP2, influences mRNA expression levels. Peripheral myelin protein 22 (PMP22) was one gene that was significantly influenced by G3BP1 depletion which led to a 2-3 fold increased expression. Depletion of PMP22 resulted in increased proliferation and the G3BP1-mediated effect on proliferation was not seen upon PMP22-depletion. This indicates a novel role for G3BP1 in the regulation of cell proliferation in breast cancer cells,

Frontiers | KDM5c Promotes Colon Cancer Cell Proliferation Through the FBXW7-c-Jun Regulatory Axis | OncologyFrontiers | KDM5c Promotes Colon Cancer Cell Proliferation Through the FBXW7-c-Jun Regulatory Axis | Oncology
KDM5c is a histone demethylase that specifically demethylates trimethylated and dimethylated H3 Lys-4 to play a central role in transcriptional repression. C-Jun is a proto-oncogene and promotes cell proliferation when ectopically accumulated, but can be ubiquitinated by SCF (FBXW7), leading to its degradation. FBXW7 is an E3 ubiquitin ligase of c-Jun, and exhibits carcinostasis in colon cancer. Here, we report that overexpression of KDM5c in human colon cancer cells results in attenuated FBXW7 transcription and accumulated c-Jun protein, leading to increased proliferation of colon cancer cells. We show that overexpression of KDM5c can result in increased c-Jun protein levels and decreased ubiquitin levels, with no significant change in mRNA levels of c-Jun. KDM5c overexpression blocks the ubiquitin-proteasome proteolytic pathway of c-Jun by down-regulating the expression of FBXW7. KDM5c down-regulation of FBXW7 occurs by demethylation of H3K4me3 at TSS and downstream of the FBXW7 gene. And interaction

The challenge to measure cell proliferation in two and three dimensions | ScholarBank@NUSThe challenge to measure cell proliferation in two and three dimensions | [email protected]
Various assays, using different strategies, are available for assessing cultured cell proliferation. These include measurement of metabolic activity (tetrazolium salts and alamarBlue), DNA quantification using fluorophores (Hoechst 33258 and PicoGreen), uptake of radioactively-labeled DNA precursors such as [3H]thymidine, and physical counting (hemocytometer). These assays are well established in characterizing cell proliferation in two-dimensional (2D), monolayer cultures of low cell densities. However, increasing interest in 3D cultures has prompted the need to evaluate the effectiveness of using these assays in high cell density or 3D cultures. We show here that typical cell proliferation assays do not necessarily correlate linearly with increasing cell densities or between 2D and 3D cultures, and are either not suitable or only rough approximations in quantifying actual cell numbers in a culture. Prudent choice of techniques and careful interpretation of data are therefore recommended when ...

p,Here, we ask how neural stem cells (NSCs) transition in the developing neocortex from a rapidly to a slowly proliferating state, a process required to maintain lifelong stem cell pools. We identify LRIG1, known to regulate receptor tyrosine kinase signaling in other cell types, as a negative regulator of cortical NSC proliferation. LRIG1 is expressed in murine cortical NSCs as they start to proliferate more slowly during embryogenesis and then peaks postnatally when they transition to give rise to a portion of adult NSCs. Constitutive or acute loss of Lrig1 in NSCs over this developmental time frame causes stem cell expansion due to increased proliferation. LRIG1 controls NSC proliferation by associating with and negatively regulating the epidermal growth factor receptor (EGFR). These data support a model in which LRIG1 dampens the stem cell response to EGFR ligands within the cortical environment to slow their proliferation as they transition to postnatal adult NSCs.,/p,. ...

Hypoxia promotes adipose-derived stem cell proliferation via VEGF | Biomedical Research and TherapyHypoxia promotes adipose-derived stem cell proliferation via VEGF | Biomedical Research and Therapy
ADSCs are a promising candidate for clinical applications. They are easily derived from adipose tissue, with strong proliferation potential. Compared with other sources of MSCs such as bone marrow, umbilical cord and umbilical cord blood, ADSCs have a shorter doubling time. Therefore, numerous studies on ADSCs, especially on ADSC in vitro proliferation, have been performed to date. To date, hypoxia has been applied on stem cell cultures including ADSC culture. This study aimed to evaluate the effects of hypoxia on ADSC proliferation.. First, ADSCs were successfully isolated and confirmed by usual methods and assays. Similarly to previous studies, the obtained ADSCs fully exhibited several MSCs characteristics, including adherence to the surface of plastic flasks with a fibroblast-like shape; they also successfully differentiated into three kinds of mesoderm cells including adipocytes, osteoblasts and chondroblasts. Flow cytometry analysis with surface markers revealed that they expressed ...

5.1. Cell proliferation and apoptosis5.1. Cell proliferation and apoptosis
Cell proliferation is a process of increasing cell number, including cell development and cell division [46]. This intern responsible to increase in cell mass and ultimately the organism development. In certain cells, proliferation is restricted while it remains continue in some of the cells throughout lifetime. In certain situation cell proliferation becomes abnormal which further augment the tumor cell formation [40]. In the body, cell proliferation process is highly regulated by cell division and apoptosis [2]. Apoptosis is programmed cell death mechanism that destroys unwanted cells and also involved in defense mechanism of the body. It also plays a role in morphological and cellular mechanisms of cell, caspases functioning, translocation of phosphatidyl serine and DNA fragmentation [43, 47]. This complex process comprises intrinsic pathway and extrinsic pathway which are also called as mitochondrial pathway and cytoplasmic pathway or death receptor pathway, respectively (Fig. 4) [5].

This is repeatedly confirmed by various mathematical models consisting of mostly ordinary differential equations. However, cell growth is limited by nutrient and its proliferation incurs a time delay. In this paper, we formulate a nutrient limited compartmental model of avascular spherical solid tumor growth with cell proliferation time delay and study its limiting dynamics. The nutrient is assumed to enter the tumor proportional to its surface area. This model is a modification of a recent model which is built on a two-compartment model of cancer cell growth with transitions between proliferating and quiescent cells. Due to the limitation of ...

The Wnt signal pathway is composed of β-catenin and transcriptional factor TCF-4 (2 , 3 , 19, 20, 21) . These factors activate the target genes that preserve the consensus motif (A/TA/TCAAAG) for TCF-4 binding in the promoter region (6) . Recent studies have shown that cyclin D1, c-myc, MMP7, and c-jun could be target genes for the Wnt signal pathway (7, 8, 9, 10) . Therefore, Wnt signal may induce cell proliferation through activation of these target genes (22, 23, 24, 25) . To our knowledge, there is no report on RCCs regarding the significance of the Wnt signal factors in cell proliferation and/or apoptosis through regulation of downstream target genes. In this study, we evaluated the significance of the Wnt signal pathway in RCC through the analysis of cyclin D1, c-myc, MMP7, and c-jun in relation to β-catenin and TCF-4 alterations.. TCF-4 expression has been intensively investigated in the epithelium of the gastrointestinal tract (26 , 27) , and the presence of splicing isoforms in TCF-4 ...

The type III transforming growth factor-β receptor inhibits proliferation, migration, and adhesion in human myeloma cellsThe type III transforming growth factor-β receptor inhibits proliferation, migration, and adhesion in human myeloma cells
Transforming growth factor-β (TGF-β) plays an important role in regulating hematopoiesis, inhibiting proliferation while stimulating differentiation when appropriate. We previously demonstrated that the type III TGF-β receptor (TβRIII, or betaglycan) serves as a novel suppressor of cancer progression in epithelial tumors; however, its role in hematologic malignancies is unknown. Here we demonstrate that TβRIII protein expression is decreased or lost in the majority of human multiple myeloma specimens. Functionally, restoring TβRIII expression in myeloma cells significantly inhibited cell growth, proliferation, and motility, largely independent of its ligand presentation role. In a reciprocal fashion, shRNA-mediated silencing of endogenous TβRIII expression enhanced cell growth, proliferation, and motility. Although apoptosis was not affected, TβRIII inhibited proliferation through induction of the cyclin-dependent kinase inhibitors p21 and p27. TβRIII further regulated myeloma cell ...

Genome-wide mutant strain collections have increased demand for high throughput cellular phenotyping (HTCP). For example, investigators use HTCP to investigate interactions between gene deletion mutations and additional chemical or genetic perturbations by assessing differences in cell proliferation among the collection of 5000 S. cerevisiae gene deletion strains. Such studies have thus far been predominantly qualitative, using agar cell arrays to subjectively score growth differences. Quantitative systems level analysis of gene interactions would be enabled by more precise HTCP methods, such as kinetic analysis of cell proliferation in liquid culture by optical density. However, requirements for processing liquid cultures make them relatively cumbersome and low throughput compared to agar.

Lack of IGF2 in mice results in diminished embryonic growth due to diminished cell proliferation. Here we show that mouse embryonic fibroblasts lacking the RNA-binding protein IMP1 (IGF2 mRNA-binding protein 1) have defective splicing and translation of IGF2 mRNAs, markedly reduced IGF2 polypeptide production, and diminished proliferation. The proliferation of the IMP1-null fibroblasts can be restored to wild-type levels by IGF2 in vitro or by re-expression of IMP1, which corrects the defects in IGF2 RNA splicing and translation. The ability of IMP1 to correct these defects is dependent on IMP1 phosphorylation at Ser181, which is catalyzed cotranslationally by mTOR complex 2 (mTORC2). Phosphorylation strongly enhances IMP1 binding to the IGF2-leader 3 5 untranslated region, which is absolutely required to enable IGF2-leader 3 mRNA translational initiation by internal ribosomal entry. These findings uncover a new mechanism by which mTOR regulates organismal growth by promoting IGF2 production in ...

Fibulin-5 downregulates Ki-67 and inhibits proliferation and invasion of breast cancer cells
Fibulins not only function as molecular bridges within the cellular microenvironment but also influence cell behavior. Thus, fibulins may contribute to create a permissive microenvironment for tumor growth but can also stimulate different mechanisms that may impede tumor progression. This is the case with Fibulin-5, which has been shown to display both tumor-promoting and tumor-protective functions by mechanisms that are not totally defined. We show new evidence on the tumor-protective functions displayed by Fibulin-5 in MCF-7, T47D and MDA-MB-231 breast cancer cells including the inhibition of invasion and proliferation capacity and hampering the ability to form mammospheres. Reduction in the level of phosphorylation of Ser residues involved in the nuclear translocation of β-catenin may underlie these antitumor effects. We also found that Fibulin-5 reduces the level of expression of Ki-67, a nuclear protein associated with cell proliferation. Moreover, reduction in Fibulin-5 expression ...

Non-small cell lung cancer (NSCLC) is a type of malignant tumor which threatens human health and life. Recently, some researches on long non-coding RNAs (lncRNAs) in NSCLC has elucidated critical regulatory roles in cell proliferation, migration, and invasion, the relative clinical significance and mechanisms of action are still unclear. This study focuses on the important role of a novel lncRNA LINC00665 in the development of NSCLC. Long intergenic non-protein coding RNA 665 gene (LINC00665) was found through microarray analysis and was measured by real-time quantitative PCR (RT-qPCR). The interactions between LINC00665 and miR-138-5p as well as the interactions between miR-138-5p and E2F3 (E2F transcription factor 3) were explored by bioinformatics analysis and dual-luciferase assays. CCK-8, transwell and mouse xenograft assays were performed to investigate the effects of LINC00665 and miR-138-5p on NSCLC proliferation and invasion. As a result, LINC00665 expression was upregulated in NSCLC ...

Upregulation of miR-614 promotes proliferation and inhibits apoptosis in ovarian cancer by suppressing PPP2R2A expressionUpregulation of miR-614 promotes proliferation and inhibits apoptosis in ovarian cancer by suppressing PPP2R2A expression
The present study, to the best of the authors knowledge, demonstrated for the first time, that miR-614 was upregulated in OC clinical tissues and cells. Increased expression of miR-614 led to the promotion of cell proliferation and colony-forming abilities, and conversely, decreased the apoptotic rate of OC cells. Additionally, PPP2R2A may act as a novel target of miR-614. The present study indicated that miR-614 may act as a novel tumor promoter in OC by targeting PPP2R2A.. Accumulating evidence suggests that miRNAs exhibit an essential role in human cancer pathological proceedings via controlling different target genes, including those involved in cell proliferation, migration, invasion, cycle and apoptosis (15-18). Dysregulation of miRNA frequently occurs in novel types of cancers, including ovarian cancer. miR-21-3p inhibits cell proliferation and invasion of ovarian cancer by targeting RNA binding protein with multiple splicing, RCC1 and BTB domain containing protein 1 and Zinc finger ...

miRNAs are emerging as critical regulators in carcinogenesis and tumor progression. Recently, microRNA-122 (miR-122) has been proved to play an important role in hepatocellular carcinoma, but its functions in the context of breast cancer (BC) remain unknown. In this study, we report that miR-122 is commonly downregulated in BC specimens and BC cell lines with important functional consequences. Overexpression of miR-122 not only dramatically suppressed cell proliferation, colony formation by inducing G1-phase cell-cycle arrest in vitro, but also reduced tumorigenicity in vivo. We then screened and identified a novel miR-122 target, insulin-like growth factor 1 receptor (IGF1R), and it was further confirmed by luciferase assay. Overexpression of miR-122 would specifically and markedly reduce its expression. Similar to the restoring miR-122 expression, IGF1R downregulation suppressed cell growth and cell-cycle progression, whereas IGF1R overexpression rescued the suppressive effect of miR-122.

Identification of FIP200 interaction with the TSC1-TSC2 complex and its role in regulation of cell size control | JCBIdentification of FIP200 interaction with the TSC1-TSC2 complex and its role in regulation of cell size control | JCB
Both cell proliferation and cell size control are fundamental biological processes that must be carefully orchestrated, and dysregulation of either can lead to diseases such as cancer. In contrast to our understanding of the mechanisms that control cell proliferation, less is known about the mechanisms that control cell size and, particularly, the mechanisms by which cell proliferation and cell size are coordinately regulated. Recently, we identified a novel protein named FIP200, which plays an important role in the regulation of cell cycle progression (Abbi et al., 2002). In this study, we showed that FIP200 can also regulate cell size through interaction with the TSC1-TSC2 complex and activation of S6K. These results identify FIP200 as a regulator that plays roles in both cell proliferation and cell size control.. Most other proteins known to play roles in both cell proliferation and cell size usually regulate these two cellular processes in a similar manner. For example, PTEN can inhibit cell ...

Micro-environmental control of gut renewal
Supervisor: Golnar Kolahgar. The intestinal epithelium constantly regenerates from stem cells, which adjust their behaviour to the changing physiological conditions the gut is exposed to. For example, stem cell proliferation rates can transiently increase to speed up regeneration after tissue loss or in response to the diet, before reverting to steady-state levels once correct tissue size is reached. This plasticity is essential for intestinal function, as lack of regeneration causes tissue atrophy whereas unrestricted stem cell proliferation promotes cancer. We use the genetically tractable Drosophila gut to identify the secreted and physical factors regulating gut plasticity. In particular, we use targeted genetic screens and functional analyses, to identify novel extracellular signalling molecules regulating cell proliferation in contexts that trigger reversible changes in gut size. As the regulation of intestinal proliferation is largely conserved between Drosophila and mammals this work has ...

The Hippo-Yap signaling pathway regulates a number of developmental and adult cellular processes, including cell fate determination, tissue growth, and tumorigenesis. Members of the scaffold protein angiomotin (Amot) family interact with several Hippo pathway components, including Yap (Yes-associated protein), and either stimulate or inhibit Yap activity. We used a combination of genetic, biochemical, and transcriptional approaches to assess the functional consequences of the Amot-Yap interaction in mice and in human cells. Mice with a liver-specific Amot knockout exhibited reduced hepatic oval cell proliferation and tumorigenesis in response to toxin-induced injury or when crossed with mice lacking the tumor suppressor Nf2. Biochemical examination of the Amot-Yap interaction revealed that the p130 splicing isoform of Amot (Amot-p130) and Yap interacted in both the cytoplasm and nucleus, which involved binding of PPxY and LPxY motifs in Amot-p130 to WW domains of Yap. In the cytoplasm, ...

THE JOURNEY FROM 2D CELL CULTURE TO ORGAN ON CHIP - The BioTalk Magazine
ECM components are the key players of 3D culture methods: ECM are tissue specific and are composed of a wide array of molecules including collagens, elastin, glycosaminoglycans, growth factors, proteoglycans; each of which plays a crucial role. For example, collagen and fibronectin are known to influence cell migration whereas integrin dependent signaling cascade influences cell proliferation and polarity.. In an experiment, 2D culture of human breast epithelial cells resulted in tumor cell like growth whereas the same cell when cultured 3 dimensionally, the cell growth was back to normal. This undoubtedly highlights the importance of ECM in regulating complex cellular responses. Over the past decade different methods for culturing cells three dimensionally have been developed. They can be broadly classified as -. 1.Scaffold based techniques Here cells are cultured in presence of cell specific ECM like matrices. Today a plethora of ECM like scaffolds have been designed and incorporated in cell ...

Background: Cisplatin, a DNA damaging agent, induces apoptosis through increasing DNA fragmentation.However, identification of intrinsic resistance molecules against Cisplatin is vital to estimate the success of therapy.Bag-1 (Bcl-2-associated anthanogene) is one anti-apoptotic protein involved in drug resistance impacting ontherapeutic efficiency. Elevated levels of this protein are related with increase cell proliferation rates, motilityand also cancer development. For this reason, we aimed to understand the role of Bag-1 expression in Cisplatininducedapoptosis in HeLa cervix cancer cells. Cisplatin decreased cell viability in time- and dose-dependentmanner in wt and Bag-1L+HeLa cells. Although, 10μM Cisplatin treatment induced cell death within 24h byactivating caspases in wt cells, Bag-1L stable transfection protected cells against Cisplatin treatment. To assess thepotential protective role of Bag-1, we first checked the expression profile of interacting anti-apoptotic partners ofBag-1. We found

Transcriptional profiling of ErbB signalling in mammary luminal epithelial cells - interplay of ErbB and IGF1 signalling...Transcriptional profiling of ErbB signalling in mammary luminal epithelial cells - interplay of ErbB and IGF1 signalling...
RESULTS: 775 genes were differentially expressed and clustered in terms of their growth factor responsiveness. As well as identifying uncharacterized genes as novel targets of ErbB2-dependent signalling, ErbB2 overexpression augmented the induction of multiple genes involved in proliferation (e.g. MYC, MAP2K1, MAP2K3), autocrine growth factor signalling (VEGF, PDGF) and adhesion/cytoskeletal regulation (ZYX, THBS1, VCL, CNN3, ITGA2, ITGA3, NEDD9, TAGLN), linking them to the hyper-poliferative and altered adhesive phenotype of the ErbB2-overexpressing cells. We also report ErbB2-dependent down-regulation of multiple interferon-stimulated genes that may permit ErbB2-overexpressing cells to resist the anti-proliferative action of interferons. Finally, IGFBP3 was unique in its pattern of regulation and we further investigated a possible role for IGFBP3 down-regulation in ErbB2-dependent transformation through suppressed IGF1 signalling. We show that IGF1-dependent signalling and proliferation were ...
