Expression pattern, regulation, and biological role of runt domain transcription factor, run, in Caenorhabditis elegans. (1/202)

The Caenorhabditis elegans run gene encodes a Runt domain factor. Runx1, Runx2, and Runx3 are the three known mammalian homologs of run. Runx1, which plays an essential role in hematopoiesis, has been identified at the breakpoint of chromosome translocations that are responsible for human leukemia. Runx2 plays an essential role in osteogenesis, and inactivation of one allele of Runx2 is responsible for the human disease cleidocranial dysplasia. To understand the role of run in C. elegans, we used transgenic run::GFP reporter constructs and a double-stranded RNA-mediated interference method. The expression of run was detected as early as the bean stage exclusively in the nuclei of seam hypodermal cells and lasted until the L3 stage. At the larval stage, expression of run was additionally detected in intestinal cells. The regulatory elements responsible for the postembryonic hypodermal seam cells and intestinal cells were separately located within a 7.2-kb-long intron region. This is the first report demonstrating that an intron region is essential for stage-specific and cell type-specific expression of a C. elegans gene. RNA interference analysis targeting the run gene resulted in an early larva-lethal phenotype, with apparent malformation of the hypodermis and intestine. These results suggest that run is involved in the development of a functional hypodermis and gut in C. elegans. The highly conserved role of the Runt domain transcription factor in gut development during evolution from nematodes to mammals is discussed.  (+info)

The common retroviral insertion locus Dsi1 maps 30 kilobases upstream of the P1 promoter of the murine Runx3/Cbfa3/Aml2 gene. (2/202)

The Dsi1 locus was identified as a common integration site for Moloney murine leukemia virus (MLV) in rat thymic lymphomas, but previous efforts to identify a gene affected by these insertions were unsuccessful. We considered the Runx3 gene a potential candidate on the basis of genetic mapping which showed that Dsi1 and Runx3 are closely linked on mouse chromosome 4 and the precedent of the related Runx2 gene, which emerged recently as a Myc-collaborating gene activated by retroviral insertion in thymic lymphomas of CD2-MYC mice. We now report the physical mapping of the Dsi1 locus to a site 30 kb upstream of the distal (P1) promoter of the murine Runx3 gene. Comparison with the syntenic region of human chromosome 1 shows that the next gene is over 250 kb 5' to Runx3, suggesting that Runx3 may be the primary target of retroviral insertions at Dsi1. Screening of CD2-MYC lymphomas for rearrangements at Dsi1 revealed a tumor cell line harboring an MLV provirus at this locus, in the orientation opposite that of Runx3. Proviral insertion was associated with very high levels of expression of Runx3, with a preponderance of transcripts arising at the P1 promoter. These results confirm that Runx3 is a target of retroviral insertions at Dsi1 and indicate that Runx3 can act as an alternative to Runx2 as a Myc-collaborating gene in thymic lymphoma.  (+info)

Causal relationship between the loss of RUNX3 expression and gastric cancer. (3/202)

Runx3/Pebp2alphaC null mouse gastric mucosa exhibits hyperplasias due to stimulated proliferation and suppressed apoptosis in epithelial cells, and the cells are resistant to growth-inhibitory and apoptosis-inducing action of TGF-beta, indicating that Runx3 is a major growth regulator of gastric epithelial cells. Between 45% and 60% of human gastric cancer cells do not significantly express RUNX3 due to hemizygous deletion and hypermethylation of the RUNX3 promoter region. Tumorigenicity of human gastric cancer cell lines in nude mice was inversely related to their level of RUNX3 expression, and a mutation (R122C) occurring within the conserved Runt domain abolished the tumor-suppressive effect of RUNX3, suggesting that a lack of RUNX3 function is causally related to the genesis and progression of human gastric cancer.  (+info)

Expression of transcription factor AML-2 (RUNX3, CBF(alpha)-3) is induced by Epstein-Barr virus EBNA-2 and correlates with the B-cell activation phenotype. (4/202)

To identify cell proteins regulated by the Epstein-Barr virus (EBV) transcription factor EBNA-2, we analyzed a cell line with conditional EBNA-2 activity by using microarray expression profiling. This led to the identification of two novel target genes induced by EBNA-2. The first of these, interleukin-16, is an immunomodulatory cytokine involved in the regulation of CD4 T cells. The second, AML-2, is a member of the Runt domain family of transcription factors. Quiescent B cells initially expressed AML-1 but, 48 h after virus infection, the levels of AML-1 decreased dramatically, whereas the amount of AML-2 protein increased. Analysis of a panel of B-cell lines indicated that AML-2 expression is normally predominant in EBV latency III, whereas AML-1 is associated with EBV latency I or EBV-negative cells. The AML genes are the first example of cell transcription factors whose expression correlates with the latency I/III phenotype.  (+info)

RUNX: a trilogy of cancer genes. (5/202)

The Runx3 transcription factor regulates development and survival of TrkC dorsal root ganglia neurons. (6/202)

The RUNX transcription factors are important regulators of linage-specific gene expression in major developmental pathways. Recently, we demonstrated that Runx3 is highly expressed in developing cranial and dorsal root ganglia (DRGs). Here we report that within the DRGs, Runx3 is specifically expressed in a subset of neurons, the tyrosine kinase receptor C (TrkC) proprioceptive neurons. We show that Runx3-deficient mice develop severe limb ataxia due to disruption of monosynaptic connectivity between intra spinal afferents and motoneurons. We demonstrate that the underlying cause of the defect is a loss of DRG proprioceptive neurons, reflected by a decreased number of TrkC-, parvalbumin- and beta-galactosidase-positive cells. Thus, Runx3 is a neurogenic TrkC neuron-specific transcription factor. In its absence, TrkC neurons in the DRG do not survive long enough to extend their axons toward target cells, resulting in lack of connectivity and ataxia. The data provide new genetic insights into the neurogenesis of DRGs and may help elucidate the molecular mechanisms underlying somatosensory-related ataxia in humans.  (+info)

Pathways in blood and vessel development revealed through zebrafish genetics. (7/202)

Studies in zebrafish have potential to contribute to understanding of the vertebrate hematopoietic and vasculogenic systems. Our research has examined the roles of several molecules in pathways that lead to the development of blood and vessels in zebrafish, and has provided insights into the regulation of these processes. Gdf6a/radar, a member of the bone morphogenetic protein (BMP) family, is expressed in the zebrafish hypochord and primitive gut endoderm; structures that flank the developing dorsal aorta and posterior cardinal vein. This pattern of expression positions Gdf6a/radar as a candidate regulator of vasculogenesis. Support for such a role has come from experiments where Gdf6a/radar function was depleted with antisense morpholino oligonucleotides. This resulted in vascular leakiness, suggesting that Gdf6a/radar is involved in maintenance of vascular integrity. The transcription factor Runx1 is known to play a critical role in mammalian definitive hematopoiesis. When Runx1 expression domains and function were analyzed in zebrafish, the importance of this gene in definitive hematopoiesis was confirmed. However there was also evidence for a wider role, including involvement in vascular development and neuropoiesis. This work has laid the foundation for an ethylnitrosourea (ENU) mutagenesis screen based on runx1 whole-mount in situ hybridzation, that aims to identify genes operative in the runx1 pathway. An additional member of the Runx family, Runx3, is also involved in developmental hematopoiesis, with a function distinct from that of Runx1. We hypothesize that Runx1 and Runx3 form a continuum of transcriptional control within the hematopoietic system. An added attraction of zebrafish is that models of human disease can be generated, and we have shown that this system has potential for the study of Runx1-mediated leukemogenesis.  (+info)

Inhibition of growth of mouse gastric cancer cells by Runx3, a novel tumor suppressor. (8/202)

We reported recently that the silencing of RUNX3 is causally related to gastric cancer in humans. Here we report that in three of four cell lines derived from N-methyl-N-nitrosourea-induced mouse glandular stomach carcinomas, Runx3 is silenced due to hypermethylation of CpG islands in the promoter region, as we also observed for human gastric cancer cells. Although two of the sites we tested in the promoter of the fourth line were not methylated, in all four cases the silencing of Runx3 could be reversed by treatment of the cells with 5'-azacytidine and trichostatin A. Interestingly, the exogenous expression of RUNX3 in cell lines that do not express the endogenous gene caused an inhibition of growth in soft agar, suggesting that anchorage-independent growth could be used as an assay of RUNX3 activity in vitro. These observations suggest that the mouse system described here may be useful as a model for the study of human gastric carcinogenesis.  (+info)

Runt-related transcription factor 1 (RUNX1) is generally considered to function as a tumor suppressor in the development of leukemia, but a growing body of evidence suggests that it has pro-oncogenic properties in acute myeloid leukemia (AML). Here we have demonstrated that the antileukemic effect mediated by RUNX1 depletion is highly dependent on a functional p53-mediated cell death pathway. Increased expression of other RUNX family members, including RUNX2 and RUNX3, compensated for the antitumor effect elicited by RUNX1 silencing, and simultaneous attenuation of all RUNX family members as a cluster led to a much stronger antitumor effect relative to suppression of individual RUNX members. Switching off the RUNX cluster using alkylating agent-conjugated pyrrole-imidazole (PI) polyamides, which were designed to specifically bind to consensus RUNX-binding sequences, was highly effective against AML cells and against several poor-prognosis solid tumors in a xenograft mouse model of AML without ...
Further we asked if VLA-4 and VLA-5 integrin upregulation is maintained by RUNX1/ETO in the transformed human leukemia cell line Kasumi-1, derived from a t(8;21)+ AML patient. Kasumi-1 cells, which express RUNX1/ETO and to a lesser extent RUNX1/ETOtr,4 bear high levels of VLA-4 whereas the integrin αL subunit is absent in these cells. We specifically down-regulated RUNX1/ETO via lentivirally delivered shRNA targeting the RUNX1/ETO breakpoint sequences (shRE), which are present in both full length and truncated forms (Online Supplementary Figure S3). At Day 4 after transduction with vectors co-expressing shRE and eGFP, α4, α5 and β1 expression levels were significantly reduced as assessed using flow cytometry, while CXCR4 levels remained unaltered (Figure 1I). Similar results were obtained with NHR2 competitive peptides (N89) (Figure 1J), which also interfere with both RUNX1/ETO forms by disrupting RUNX1/ETO tetramer formation.6 These results suggest that integrin subunit expression remains ...

Runt-related transcription factor 1 (RUNX1) is a heterodimeric transcription factor that binds to the core element of many enhancers and promoters and can accelerate apoptosis in various tumors. However, the regulatory mechanisms underlying RUNX1 expression in neuroblastoma (NB), a highly malignant tumor in childhood, remain largely unclear. In this study, we aimed to assess the role of RUNX1 in NB and to reveal the underlying mechanisms that may contribute to finding a potential therapeutics strategy against NB. Growth, invasion, metastasis and angiogenesis were assessed using Cell Counting Kit-8 (CCK-8) immunocytochemistry, and studies involving soft agar, cell invasion, tube formation and whole animals. The levels of expression were measured using real-time quantitative PCR for RNA, Western blot and immunostaining analyses for proteins. Luciferase reporter and chromatin immunoprecipitation assays indicated that RUNX1 directly binds within the BIRC5, CSF2RB and NFKBIA promoter regions to facilitate

BACKGROUND: Runx transcription factors play critical roles in the developmental control of cell fate and contribute variously as oncoproteins and tumor suppressors to leukemia and other cancers. To discover fundamental Runx functions in the cell biology of animal development, we have employed morpholino antisense-mediated knockdown of the sea urchin Runx protein SpRunt-1. Previously we showed that embryos depleted of SpRunt-1 arrest development at early gastrula stage and underexpress the conventional protein kinase C SpPKC1. RESULTS: We report here that SpRunt-1 deficiency leads to ectopic cell proliferation and extensive apoptosis. Suppression of the apoptosis by pharmacological inhibition of caspase-3 prevents the ectopic proliferation and rescues gastrulation, indicating that many of the overt defects obtained by knockdown of SpRunt-1 are secondary to the apoptosis. Inhibition or knockdown of SpPKC1 also causes apoptosis, while cell survival is rescued in SpRunt-1 morphant embryos coinjected with
The mechanism underlying the lineage decision made by CD4(+)CD8(+) double-positive (DP) thymocytes that give rise to two T lymphocyte subset with distinct functionalities, that is, helper and cytotoxic T cells, remains a major issue in immunology. The lineage decision process involves several phases and terminates when cells loose their developmental plasticity to become the alternate lineage. A detailed picture of the transcription factor network governing helper versus cytotoxic-lineage decision has recently emerged. Studies published only past year provided new insights into how the expression of ThPOK, a central transcription factor for helper T cell development, is regulated. It has now become evident that an antagonistic interplay between ThPOK and Runx transcription factor complexes plays an essential role in thwarting an alternate fate during the commitment process.

Estrogen receptor α (ER α) and androgen receptor (AR) are master transcription factors in the breast and prostate, respectively. They are commonly known in development of sexual characteristics. However, both ERα and AR have been known to be involved in breast cancer (BCa) and prostate cancer (PCa) progression, respectively. The Runx family of transcription factors plays a role in hematopoiesis (Runx1), skeletogenesis (Runx2) and neurogenesis (Runx3). In addition, Runx proteins inhibit cell cycle progression, and have been assigned tumor suppressor roles in various contexts. Because both BCa and PCa cells metastasize to bone at high frequency, investigators have interrogated the possibility that they share characteristics with osteoblasts. Indeed, BCa and PCa cells were found to have osteomimetic properties, including expression of Runx2 and Runx2-target genes otherwise expressed by osteoblasts.

We previously demonstrated that the GCTs are involuted by the epithelial deletion of core binding factor β (CBFβ), a transcription factor that physically interacts with any of the Runt-related transcription factor (RUNX) proteins (RUNX1, 2 and 3). This result clearly demonstrates that the Runx /Cbfb signaling pathway is indispensable in the development of the GCTs. However, it is not clear which of the RUNX proteins plays useful role in the development of the GCTs by activating the Runx /Cbfb signaling pathway. Past studies have revealed that the Runx /Cbfb signaling pathway plays important roles in various aspects of development and homeostatic events. Moreover, the Runx genes have different temporospatial ...
The Runt related transcription factors (RUNX) are recognized as key players in suppressing or promoting tumor growth. RUNX3, a member of this family, is known as a tumor suppressor in many types of cancers, although such a paradigm was challenged by some researchers. The TGF-β pathway governs major upstream signals to activate RUNX3. RUNX3 protein consists of several regions and domains. The Runt domain is a conserved DNA binding domain and is considered as the main part of RUNX proteins since. Herein, we compared the effects of Runt domains and full-Runx3 in cell viability by designing two constructs of Runx3, including N-terminal region and Runt domain. We investigated the effect of full-Runx3, N-t, and RD on growth inhibition in AGS, MCF-7, A549, and HEK293 cell lines which are different in TGF-β sensitivity, in the absence and presence of TGF-β. The full length RUNX3 did not notably inhibit growth of these cell lines while, the N-t and RD truncates showed different trends in these cell lines.

The nuclear matrix protein, NMP-2, was originally identified as an osteoblast-specific DNA-binding complex localized exclusively to the nuclear matrix. NMP-2 was shown to recognize two binding sites, site A (nt-605 to -599) and site B (nt -441 to -435), in the rat bone-specific osteocalcin gene promoter. This study shows that the NMP-2 binding sites A and B as well as a third NMP-2 binding site (nt -135 to -130) constitute a consensus sequence, ATGCTGGT, and represent an AML-1 recognition motif. AML-1 is a member of the AML transcription factor family which is associated with acute myelogenous leukemia and binds to the sequence TGCTGGT via its DNA-binding runt domain. Electrophoretic mobility shift assays reveal that a component of NMP-2 is a member of the AML/PEBP2/runt domain transcription factor family based on cross-competition with AML-1 consensus oligonucleotide. Limited immunoreactivity of NMP-2 with a polyclonal N-terminal AML-1 antibody and inability of the AML-1 partner protein CBF-beta to
Runt-related transcription factor 1 (Runx1), a master regulator of hematopoiesis, is expressed in preosteoclasts. Previously we evaluated the bone phenotype of CD11b-Cre Runx1(fl/fl) mice and demonstrated enhanced osteoclasts and decreased bone mass in males. However, an assessment of the effects of Runx1 deletion in female osteoclast precursors was impossible with this model. Moreover, the role of Runx1 in myeloid cell differentiation into other lineages is unknown. Therefore, we generated LysM-Cre Runx1(fl/fl) mice, which delete Runx1 equally (∼80% deletion) in myeloid precursor cells from both sexes and examined the capacity of these cells to differentiate into osteoclasts and phagocytic and antigen-presenting cells. Both female and male LysM-Cre Runx1(fl/fl) mice had decreased trabecular bone mass (72% decrease in bone volume fraction) and increased osteoclast number (2-3 times) (P < .05) without alteration of osteoblast histomorphometric indices. We also demonstrated that loss of Runx1 in ...
BACKGROUND: Aberrant expression of the transcription factor RUNX2 in prostate cancer has a number of important consequences including increased resistance to apoptosis, invasion and metastasis to bone. We previously demonstrated that hypoxia up-regulated RUNX2 in tumour cells, which in turn up-regulated the anti-apoptotic factor Bcl-2. Here, we investigate the impact of nitric oxide (NO) on RUNX2 and Bcl-2 expression in prostate cancer and further, how RUNX2 over-expression can impact tumour growth, angiogenesis and oxygenation in vivo. METHODS: The effect of NO levels on RUNX2 and thus Bcl-2 expression was examined in prostate cancer cells in vitro using methods including gene and protein expression analyses, nitrite quantitation, protein-DNA interaction assays (ChIP) and viability assays (XTT). The effect of RUNX2 over-expression on tumour physiology (growth, oxygenation and angiogenesis) was also assessed in vivo using LNCaP xenografts. RESULTS: A low (but not high) concentration of NO (10microM)
Sometimes, a lot of people discover the same protein and so it gets a lot of names, like Runt-related transcription factor 2 (Runx2), which is also known as: Cbfa1, Osf2, AML3, Til1, and Pebp2 αA or PPB2αA… talk about having an identity crisis!. After writing my list, I Googled funny gene names to see what other funny names are out their and discovered on this site that there are waaaaaaay better gene names that Ive never heard of before (probably the best on this list are cheap date, lunatic fringe, grim and reaper (which work together to control cell death), and INDY, which makes mutant fruit flies live twice as long… its an acronym for Im not dead yet (from Monty Python and the Holy Grail).. ...
Loss of RUNX1/ETO Triggers C/EBPα-Driven Reorganization of the Leukemic Transcriptional Network(A) RUNX1/ETO and CEBPA mRNA expression levels in Kasumi-1 cells
The Runx family of transcription factors supports cell fate determination, cell cycle regulation, global protein synthesis control, and genetic as well as epigenetic regulation of target genes. Runx1, which is essential for hematopoiesis; Runx2, which is required for osteoblast differentiation; and Runx3, which is involved in neurologic and gut development; are expressed in the growth plate during chondrocyte maturation, and in the chondrocytes of permanent cartilage structures. While Runx2 is known to control genes that contribute to chondrocyte hypertrophy, the functions of Runx1 and Runx3 during chondrogenesis and in cartilage tissue have been less well studied. The goals of this project were to characterize expression of Runx proteins in articular cartilage and differentiating chondrocytes and to determine the contribution of Runx1 to osteoarthritis (OA). Here, the expression pattern of Runx1 and Runx2 was characterized in normal bovine articular cartilage. Runx2 is expressed at higher levels in
The t(8;21) acute myeloid leukemia (AML)-associated oncoprotein AML1-ETO disrupts normal hematopoietic differentiation. Here, we have investigated its effects on the transcriptome and epigenome in t(8,21) patient cells. AML1-ETO binding was found at promoter regions of active genes with high levels of histone acetylation but also at distal elements characterized by low acetylation levels and binding of the hematopoietic transcription factors LYL1 and LMO2. In contrast, ERG, FLI1, TAL1, and RUNX1 bind at all AML1-ETO-occupied regulatory regions, including those of the AML1-ETO gene itself, suggesting their involvement in regulating AML1-ETO expression levels. While expression of AML1-ETO in myeloid differentiated induced pluripotent stem cells (iPSCs) induces leukemic characteristics, overexpression increases cell death. We find that expression of wild-type transcription factors RUNX1 and ERG in AML is required to prevent this oncogene overexpression. Together our results show that the interplay ...
Background. Members of the Runx gene family encode transcription factors that bind to DNA in a sequence-specific manner. Among the three Runx proteins, Runx2 comprises 607 amino acid (aa) residues, is expressed in bone, and plays crucial roles in osteoblast differentiation and bone development. We examined whether the Runx2 gene is also expressed in testes. Methods. Murine testes from 1-, 2-, 3-, 4-, and 10-week-old male mice of the C57BL/6J strain and W∕Wv strain were used throughout the study. Northern Blot Analyses were performed using extracts form the murine testes. Sequencing of cDNA clones and 5′-rapid amplification of cDNA ends were performed to determine the full length of the transcripts, which revealed that the testicular Runx2 comprises 106 aa residues coding novel protein. Generating an antiserum using the amino-terminal 15 aa of Runx2 (Met1 to Gly15) as an antigen, immunoblot analyses were performed to detect the predicted polypeptide of 106 aa residues with the initiating Met1.

Work from Dr. Rafiis laboratory, among others, has revealed the heterogeneity of endothelial cells, which comprise over 140 different types of endothelium in the human body. Each organ or tumor is vascularized by a specialized endothelium. It is believed that transcription factors belonging to the Ets family, such as Ets variant 2 (ETV2), Fli1 and the Ets-related gene (Erg), make endothelial cells organ-specific. Endothelial cells are important niche cells for hematopoietic stem cells (HSC) and their use as feeder cells in culture allows the expansion of HSC by ~150-fold.1 As a refinement, a combination of reprogramming factors, including FBJ murine osteosarcoma viral oncogene homolog B (FOSB), growth factor independent 1 transcriptional repressor (GFI1), runt-related transcription factor 1 (RUNX1) and SPI1 (which encodes PU.1), can be combined with sustained vascular niche induction to generate HSC that are endowed with secondary repopulating activity.. However, a maladapted vascular niche can ...
TY - JOUR. T1 - New challenges in integrated diagnosis by imaging and osteo-immunology in bone lesions. AU - Schiano, Concetta. AU - Soricelli, Andrea. AU - de Nigris, Filomena. AU - Napoli, Claudio. PY - 2018/12/20. Y1 - 2018/12/20. N2 - INTRODUCTION: High-resolution imaging is the gold standard to measure the functional and biological features of bone lesions. Imaging markers have allowed the characterization both of tumour heterogeneity and metabolic data. Besides, ongoing studies are evaluating a combined use of imaging markers, such as SUVs, MATV, TLG, ADC from PET and MRI techniques respectively, and several biomarkers spanning from chemokine immune-modulators, such as PD-1, RANK/RANKL, CXCR4/CXCL12 to transcription factors, such as TP53, RB1, MDM2, RUNX family, EZH2, YY1, MAD2. Osteoimmunology may improve diagnosis and prognosis leading to precision medicine in bone lesion treatment. Areas covered: We investigated modalities (molecular and imaging approach) useful to identify bone ...

Yano et al show that TD-198946 strongly induced in vitro chondrogenic differentiation of progenitors, as evidenced by a marked increase in the chondrogenic markers type II collagen and aggrecan; it did this without promoting hypertrophy (type X collagen and metalloprotease 13).8. This interesting balance between chondrogenesis and hypertrophic differentiation may be because TD-198946 exerts its effect through regulating the expression of Runx1, a known inducer of chondrogenic differentiation and a suppressor of the subsequent hypertrophy.10 The mammalian Runx protein family comprises three transcription factors: Runx1, Runx2 and Runx3. All Runx proteins are expressed during chondrogenesis; however, experimental results show a distinct role for Runx proteins in chondrogenesis and subsequent chondrocyte maturation.12 ,13 Runx1 is highly expressed during chondrogenesis in comparison with Runx2. Overall, the expression of Runx1 remained significantly higher than Runx2 expression during early limb ...
2018 The Author(s) Oncogenic transcription factors such as the leukemic fusion protein RUNX1/ETO, which drives t(8;21) acute myeloid leukemia (AML), constitute cancer-specific but highly challenging therapeutic targets. We used epigenomic profiling data for an RNAi screen to interrogate the transcriptional network maintaining t(8;21) AML. This strategy identified Cyclin D2 (CCND2) as a crucial transmitter of RUNX1/ETO-driven leukemic propagation. RUNX1/ETO cooperates with AP-1 to drive CCND2 expression. Knockdown or pharmacological inhibition of CCND2 by an approved drug significantly impairs leukemic expansion of patient-derived AML cells and engraftment in immunodeficient murine hosts. Our data demonstrate that RUNX1/ETO maintains leukemia by promoting cell cycle progression and identifies G1 CCND-CDK complexes as promising therapeutic targets for treatment of RUNX1/ETO-driven AML. Using in vitro and in vivo screens to identify essential RUNX1/ETO transcriptional targets in AML, Martinez-Soria ...
Our previous reports indicated that (+)-cholesten-3-one induces osteogenic differentiation of bone marrow mesenchymal stem cells (MSCs) by activating vitamin D receptor (VDR). However, whether and how miRNAs modulate osteogenic differentiation induced by (+)-cholesten-3-one have not been explored. In this study, miRNA array profiling and further validation by quantitative real-time PCR revealed that miR-351 was downregulated during (+)-cholesten-3-one-induced osteogenic differentiation of MSCs. Overexpression of miR-351 by miR-351 precursor transfection markedly inhibited the expression of osteoblast-specific genes, such as alkaline phosphatase (ALP), collagen type II, osteopontin (OPN), and runt-related transcription factor 2 (RUNX2), which consequently decreased a number of calcium mineralized nodules ...
The molecular mechanisms that transduce the osteoblast response to physical forces in the bone microenvironment are poorly understood. Here, we used genetic and pharmacological experiments to determine whether the polycystins PC1 and PC2 (encoded by Pkd1 and Pkd2) and the transcriptional coactivator TAZ form a mechanosensing complex in osteoblasts. Compound-heterozygous mice lacking 1 copy of Pkd1 and Taz exhibited additive decrements in bone mass, impaired osteoblast-mediated bone formation, and enhanced bone marrow fat accumulation. Bone marrow stromal cells and osteoblasts derived from these mice showed impaired osteoblastogenesis and enhanced adipogenesis. Increased extracellular matrix stiffness and application of mechanical stretch to multipotent mesenchymal cells stimulated the nuclear translocation of the PC1 C-terminal tail/TAZ (PC1-CTT/TAZ) complex, leading to increased runt-related transcription factor 2-mediated (Runx2-mediated) osteogenic and decreased PPARγ-dependent adipogenic ...
core binding factor alpha: core binding factor plays a key role in several development pathways and in human disease; has been sequenced
The pathogenesis of PDAC involves genetic alterations, such as K-ras protooncogene mutations, mutations of the p53, p16, and Smad4 tumour suppressor genes, and other less common mutations.2 In addition, there are numerous epigenetic alterations, including altered expression of several growth factors and their receptors.3 For example, PDACs overexpress all TGFβ isoforms and their receptors, and overexpression of these ligands and receptors is often associated with shortened postoperative survival of patients with pancreatic cancer.14,15. The TGFβ pathway is carefully regulated, with Smad proteins as the key component in the signal transduction pathway. In addition, other regulators, such as transcription factors, which facilitate Smad binding to target promoters, may provide routes for feedback and crosstalk.16 For example, members of the CBFA (core binding factor A) family of transcription factors act both as targets and partners of activated Smads. This family, also termed the Runx family, ...

Osteoporosis results from the imbalance between bone resorption and bone formation, and restoring the normal balance of bone remodeling is highly desirable for identification of better treatment. In this study, using a cell-based high-throughput screening model representing Runt-related transcription factor 2 (RUNX2) transcriptional activity, we identified a novel small-molecular-weight compound, T63, as an efficient up-regulator of osteogenesis. T63 increased the alkaline phosphatase (ALPL) activity and mineralization as well as gene expression of Alpl and other osteogenic marker genes in mouse osteoblasts and mesenchymal stem cell-like cells. Upon induction of osteoblast differentiation, T63 inhibited adipogenic differentiation in the pluripotent mesenchymal cells. Consistently, T63 up-regulated RUNX2 mRNA and protein levels, and knockdown of RUNX2 reduced the osteogenic role of T63. Mechanistically, T63 activated both BMPs and WNT/β-catenin signaling pathways. Inhibition of either signaling pathway
We previously published a detailed survey of the spatio‐temporal expression of Runx3 during embryonic development (Levanon et al, 2001). Runx3 expression was examined at embryonic day (E) 10.5 and between E14.5 and E16.5, and compared to the expression pattern of Runx1. Immunohistochemistry (IHC) and knock‐in (KI) β‐galactosidase activity (LacZ staining) were used in parallel throughout this analysis to rigorously determine the expression patterns of the two TFs. Runx3 and Runx1 were readily detected in different compartments of the haematopoietic system and also in the dorsal root ganglia (DRG), epidermal appendages and developing skeletal elements (Levanon et al, 2001). However, regarding epithelia an interesting distinction was noted in the expression pattern of Runx1 and Runx3. While Runx1 was expressed in various epithelia including mucosa of the oesophagus and stomach, the salivary glands ducts and the olfactory and respiratory mucosa, Runx3 expression was undetectable in these ...

Results We compared the percentages of expression of Runx2 into the HD and OA groups: no statistically significant difference in the Runx2 expression after the stimulation with the SP was found in both groups, while a statistically significant increase with IGF-1 and TNF-α in HD group (p: 0.08 and 0.043 respectively). In the OA osteoblasts, we found a tendency to decrease the Runx2 expression with IGF-1 and TNF-α (p: 0.068 for both). The comparison HD vs OA showed a non-statistically significant difference between basal values and after the stimulation with SP (p: 0.086) while we found a statistically significant difference with IGF-1 and TNF-α (p: 0.014 for both). We did not find any influence of gender in Runx2 expression. The immunocytochemistry confirmed the findings of Western Blot analysis. ...
