Experiments with knock-out mice have demonstrated that CCAAT-enhancer binding protein-alpha is essential for the functioning and differentiation of HEPATOCYTES and ADIPOCYTES.CCAAT-Enhancer-Binding Proteins: A class of proteins that were originally identified by their ability to bind the DNA sequence CCAAT. The typical CCAAT-enhancer binding protein forms dimers and consists of an activation domain, a DNA-binding basic region, and a leucine-rich dimerization domain (LEUCINE ZIPPERS). CCAAT-BINDING FACTOR is structurally distinct type of CCAAT-enhancer binding protein consisting of a trimer of three different subunits.CCAAT-Enhancer-Binding Protein-beta: A CCAAT-enhancer-binding protein found in LIVER; INTESTINES; LUNG and ADIPOSE TISSUE.

It plays a key role in G0 PHASE mammary EPITHELIAL CELL growth arrest, and it is involved in transcriptional regulation of INTERLEUKIN 1; INTERLEUKIN 6; and TUMOR NECROSIS FACTOR-ALPHA.DNA-Binding Proteins: Proteins which bind to DNA. The family includes proteins which bind to both double- and single-stranded DNA and also includes specific DNA binding proteins in serum which can be used as markers for malignant diseases.Adipocytes: Cells in the body that store FATS, usually in the form of TRIGLYCERIDES.

Lines have been developed using several different strains of mice. Tissues are usually fibroblasts derived from mouse embryos but other types and sources have been developed as well. The 3T3 lines are valuable in vitro host systems for oncogenic virus transformation studies, since 3T3 cells possess a high sensitivity to CONTACT INHIBITION.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.PPAR gamma: A nuclear transcription factor.

A cell may contain more than one nucleus. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)Myelopoiesis: Formation of MYELOID CELLS from the pluripotent HEMATOPOIETIC STEM CELLS in the BONE MARROW via MYELOID STEM CELLS. Myelopoiesis generally refers to the production of leukocytes in blood, such as MONOCYTES and GRANULOCYTES. This process also produces precursor cells for MACROPHAGE and DENDRITIC CELLS found in the lymphoid tissue.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.GTP-Binding Protein alpha Subunits: The GTPase-containing subunits of heterotrimeric GTP-binding proteins. When dissociated from the heterotrimeric complex these subunits interact with a variety of second messenger systems. Hydrolysis of GTP by the inherent GTPase activity of the subunit causes it to revert to its inactive (heterotrimeric) form. The GTP-Binding protein alpha subunits are grouped into families according to the type of action they have on second messenger systems.Genes, Reporter: Genes whose expression is easily detectable and therefore used to study promoter activity at many positions in a target genome. In recombinant DNA technology, these genes may be attached to a promoter region of interest.DNA: A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).Blotting, Western: Identification of proteins or peptides that have been electrophoretically separated by blot transferring from the electrophoresis gel to strips of nitrocellulose paper, followed by labeling with antibody probes.Chromatin Immunoprecipitation: A technique for identifying specific DNA sequences that are bound, in vivo, to proteins of interest.

Primers are used extensively in genetic and molecular biology techniques.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.Luciferases: Enzymes that oxidize certain LUMINESCENT AGENTS to emit light (PHYSICAL LUMINESCENCE).

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.HL-60 Cells: A promyelocytic cell line derived from a patient with ACUTE PROMYELOCYTIC LEUKEMIA. HL-60 cells lack specific markers for LYMPHOID CELLS but express surface receptors for FC FRAGMENTS and COMPLEMENT SYSTEM PROTEINS.

It is produced by many different cells including T-LYMPHOCYTES; MONOCYTES; and FIBROBLASTS.Immunohistochemistry: Histochemical localization of immunoreactive substances using labeled antibodies as reagents.Monocyte-Macrophage Precursor Cells: Parent cells in the lineage that gives rise to MONOCYTES and MACROPHAGES.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.Cloning, Molecular: The insertion of recombinant DNA molecules from prokaryotic and/or eukaryotic sources into a replicating vehicle, such as a plasmid or virus vector, and the introduction of the resultant hybrid molecules into recipient cells without altering the viability of those cells.Cell Proliferation: All of the processes involved in increasing CELL NUMBER including CELL DIVISION.Proto-Oncogene Proteins: Products of proto-oncogenes.

Thapsigargin suppresses phorbol ester-dependent human involucrin promoter activity by suppressing CCAAT-enhancer-binding protein alpha (C/EBPalpha) DNA binding. (1/560)

Human involucrin (hINV) is a keratinocyte differentiation marker expressed in the suprabasal epidermal layers. In cultured keratinocytes hINV mRNA levels are increased 10-fold by a 24-h treatment with 50 ng/ml PMA, an agent that promotes keratinocyte differentiation. Previous studies show that thapsigargin (TGN), an agent that depletes intracellular calcium stores, inhibits keratinocyte differentiation. In the present study we show that TGN inhibits the PMA-dependent, differentiation-associated, increase in hINV mRNA levels and hINV promoter activity. Inhibition is half-maximal at 10 nM and maximal at 100 nM TGN. Neither basal hINV promoter activity nor glyceraldehyde-3-phosphate dehydrogenase mRNA levels are inhibited. Mutation of a functionally important CAATT-enhancer-binding protein (C/EBP) site within the hINV promoter proximal regulatory region eliminates the regulation, suggesting that TGN may effect C/EBP-dependent promoter activation. Consistent with this hypothesis, TGN inhibits C/EBPalpha-dependent promoter activation via a mechanism that involves inhibition of C/EBPalpha binding to DNA without changing C/EBPalpha protein levels. These results suggest that TGN interferes with hINV expression by interfering with C/EBP transcription-factor function.  (+info)

Identification and characterization of leptin-containing intracellular compartment in rat adipose cells. (2/560)

The major leptin-containing membrane compartment was identified and characterized in rat adipose cells by means of equilibrium density and velocity sucrose gradient centrifugation. This compartment appears to be different from peptide-containing secretory granules present in neuronal, endocrine, and exocrine cells, as well as from insulin-sensitive GLUT-4-containing vesicles abundant in adipocytes. Exocytosis of both leptin- and GLUT-4-containing vesicles can be induced by insulin; however, only leptin secretion is responsive to serum stimulation. This latter effect is resistant to cycloheximide, suggesting that serum triggers the release of a stored pool of presynthesized leptin molecules. We conclude that regulated secretion of leptin and insulin-dependent translocation of GLUT-4 represent different pathways of membrane trafficking in rat adipose cells. NIH 3T3 cells ectopically expressing CAAT box enhancer binding protein-alpha and Swiss 3T3 cells expressing peroxisome proliferator-activated receptor-gamma undergo differentiation in vitro and acquire adipocyte morphology and insulin-responsive glucose uptake. Only the former cell line, however, is capable of leptin secretion. Thus different transcriptional mechanisms control the developmental onset of these two major and independent physiological functions in adipose cells.  (+info)

Role of C/EBP homologous protein (CHOP-10) in the programmed activation of CCAAT/enhancer-binding protein-beta during adipogenesis. (3/560)

Hormone induction of growth-arrested preadipocytes triggers mitotic clonal expansion followed by expression of CCAAT/enhancer-binding protein (C/EBP)alpha and differentiation into adipocytes. The order of these events is critical because C/EBPalpha is antimitotic and its expression prematurely would block the mitotic clonal expansion required for differentiation. C/EBPbeta, a transcriptional activator of the C/EBPalpha gene, is expressed early in the differentiation program, but lacks DNA-binding activity and fails to localize to centromeres until preadipocytes traverse the G(1)-S checkpoint of mitotic clonal expansion. Evidence is presented that dominant-negative CHOP-10 expressed by growth-arrested preadipocytes transiently sequesters C/EBPbeta by heterodimerization. As preadipocytes reach S phase, CHOP-10 is down-regulated, apparently releasing C/EBPbeta from inhibitory constraint and allowing transactivation of the C/EBPalpha gene. In support of these findings, up-regulation of CHOP-10 with the protease inhibitor N-acetyl-Leu-Leu-norleucinal prevents activation of C/EBPbeta, expression of C/EBPalpha, and adipogenesis.  (+info)

Sequential repression and activation of the CCAAT enhancer-binding protein-alpha (C/EBPalpha ) gene during adipogenesis. (4/560)

CCAAT enhancer-binding protein-alpha (C/EBPalpha) functions as a pleiotropic transcriptional activator of adipocyte genes during adipogenesis. Nuclear factor C/EBP undifferentiated protein (CUP), an isoform of activator protein-2alpha (AP-2alpha), binds to repressive elements in the C/EBPalpha gene promoter, silencing the gene until late in the differentiation program. The CUP regulatory element overlaps a Sp (GT-box) element in the promoter to which Sp3 (or Sp1) can bind. Binding by Sp3 or Sp1 and CUP/AP2-alpha is mutually exclusive. Sp3 is a strong transcriptional activator of the C/EBPalpha gene promoter in 3T3-L1 preadipocytes and Schneider cells, this activation being repressed by CUP/AP-2alpha. Sp3 is expressed throughout differentiation, whereas CUP/AP-2alpha, which is expressed only by preadipocytes, is down-regulated during differentiation coincident with transcription of the C/EBPalpha gene. Thus, CUP/AP-2alpha delays access of Sp3 to the Sp regulatory element, preventing premature expression of C/EBPalpha and thereby interference by C/EBPalpha (which is antimitotic) with mitotic clonal expansion, an essential early event in the differentiation program.  (+info)

CREB (cAMP response element binding protein) and C/EBPalpha (CCAAT/enhancer binding protein) are required for the superstimulation of phosphoenolpyruvate carboxykinase gene transcription by adenoviral E1a and cAMP. (5/560)

In the present study, we observed superstimulated levels of cAMP-stimulated transcription from the phosphoenolpyruvate carboxykinase (PEPCK) gene promoter in cells infected with wild-type adenovirus expressing 12 S and 13 S E1a proteins, or in cells expressing 13 S E1a alone. cAMP-stimulated transcription was inhibited in cells expressing only 12 S E1a, but slightly elevated in cells expressing E1a proteins with mutations in conserved regions 1 or 2, leading us to conclude that the superstimulation was mediated by conserved region 3 of 13 S E1a. E1a failed to enhance cAMP-stimulated transcription from promoters containing mutations that abolish binding by cAMP response element binding protein (CREB) or CCAAT/enhancer binding proteins (C/EBPs). This result was supported by experiments in which expression of dominant-negative CREB and/or C/EBP proteins repressed E1a- and cAMP-stimulated transcription from the PEPCK gene promoter. In reconstitution experiments using a Gal4-responsive promoter, E1a enhanced cAMP-stimulated transcription when chimaeric Gal4-CREB and Gal4-C/EBPalpha were co-expressed. Phosphorylation of CREB on serine-133 was stimulated in cells treated with dibutyryl cAMP, whereas phosphorylation of C/EBPalpha was increased by E1a expression. Our data support a model in which cAMP agonists increase CREB activity and stimulate PEPCK gene transcription, a process that is enhanced by E1a through the phosphorylation of C/EBPalpha.  (+info)

The rat ortholog of the presumptive flounder antifreeze enhancer-binding protein is a helicase domain-containing protein. (6/560)

The expression of winter flounder liver-type antifreeze protein (wflAFP) genes is tissue-specific and under seasonal and hormonal regulation. The only intron of the major wflAFP gene was demonstrated to be a liver-specific enhancer in both mammalian cell lines and flounder hepatocytes. Element B, the core enhancer sequence, was shown to interact specifically with a liver-enriched transcription factor, CCAAT/enhancer-binding protein alpha (C/EBPalpha), as well as a presumptive antifreeze enhancer-binding protein (AEP). In this study, the identity of the rat AEP ortholog was revealed via its DNA-protein interaction with element B. It is a helicase-domain-containing protein, 988 amino acids in length, and is homologous to mouse Smubp-2, hamster Rip-1 and human Smubp-2. The specific binding between element B and AEP was confirmed by South-Western analysis and gel retardation assays. Residues in element B important to this interaction were identified by methylation interference assays. Mutation on one of the residues disrupted the binding between element B and AEP and its enhancer activity was significantly reduced, suggesting that AEP is essential for the transactivation of the wflAFP gene intron. The rat AEP is ubiquitously expressed in various tissues, and the flounder homolog is present as shown by genomic Southern analysis. The potential role of AEP in regulating the flounder AFP gene expression is discussed.  (+info)

Interferon-gamma-induced regulation of peroxisome proliferator-activated receptor gamma and STATs in adipocytes. (7/560)

Interferon-gamma (IFN-gamma) is known primarily for its roles in immunological responses but also has been shown to affect fat metabolism and adipocyte gene expression. To further investigate the effects of IFN-gamma on fat cells, we examined the effects of this cytokine on the expression of adipocyte transcription factors in 3T3-L1 adipocytes. Although IFN-gamma regulated the expression of several adipocyte transcription factors, IFN-gamma treatment resulted in a rapid reduction of both peroxisome proliferator-activated receptor (PPAR) protein and mRNA. A 48-h exposure to IFN-gamma also resulted in a decrease of both CCAAT/enhancer-binding alpha and sterol regulatory element binding protein (SREBP-1) expression. The short half-life of both the PPARgamma mRNA and protein likely contributed to the rapid decline of both cytosolic and nuclear PPARgamma in the presence of IFN-gamma. Our studies clearly demonstrated that the IFN-gamma-induced loss of PPARgamma protein is partially inhibited in the presence of two distinct proteasome inhibitors. Moreover, IFN-gamma also inhibited the transcription of PPARgamma, which was accompanied by a decrease in PPARgamma mRNA accumulation. In addition, exposure to IFN-gamma resulted in a substantial increase in STAT 1 expression and a small increase in STAT 3 expression. IFN-gamma treatment of 3T3-L1 adipocytes (48-96 h) resulted in a substantial inhibition of insulin-sensitive glucose uptake. These data clearly demonstrate that IFN-gamma treatment results in the development of insulin resistance, which is accompanied by the regulation of various adipocyte transcription factors, in particular the synthesis and degradation of PPARgamma.  (+info)

Hormonal signaling and transcriptional control of adipocyte differentiation. (8/560)

Recent advances regarding the biology of adipose tissue have identified the adipocyte as an important mediator in many physiologic and pathologic processes regarding energy metabolism. Consideration for a central role of adipose tissue in the development of obesity, cardiovascular disease and noninsulin-dependent diabetes mellitus has resulted in new incentives toward understanding the complexities of adipocyte differentiation. Current knowledge of this process includes a cascade of transcriptional events that culminate in the expression of peroxisome proliferator-activated receptor-gamma (PPARgamma) and CCAAT/enhancer binding protein-alpha (C/EBPalpha). These prominent adipogenic transcription factors have been shown to regulate, directly or indirectly, the gene expression necessary for the development of the mature adipocyte. Hormonal and nutritional signaling that impinges on these trans-acting factors provides a molecular link between lipids and lipid-related compounds and the gene expression important for glucose and lipid homeostasis. Knowledge concerning the transcriptional events mediating adipocyte differentiation provides a basis for understanding the physiologic processes associated with adipose tissue as well as for the development of therapeutic interventions in obesity and its related disorders.  (+info)

Adipocyte differentiation is a developmental process that is critical for metabolic homeostasis and nutrient signaling. The mammalian target of rapamycin (mTOR) mediates nutrient signaling to regulate cell growth, proliferation, and diverse cellular differentiation. It has been reported that rapamycin, the inhibitor of mTOR and an immunosuppressant, blocks adipocyte differentiation, but the mechanism underlying this phenomenon remains unknown. Here we show that mTOR plays a critical role in 3T3-L1 preadipocyte differentiation and that mTOR kinase activity is required for this process. Rapamycin specifically disrupted the positive transcriptional feedback loop between CCAAT/enhancer-binding protein-alpha and peroxisome proliferator-activated receptor-gamma (PPAR-gamma), two key transcription factors in adipogenesis, by directly targeting the transactivation activity of PPAR-gamma. In addition, we demonstrate for the first time that PPAR-gamma activity is dependent on amino acid sufficiency, ...
TNF-a was originally identified as a macrophage product implicated in the metabolic disturbances of chronic inflammation and malignancy. Later on, its biological actions were shown to further extend to anorexia, weight loss, and insulin resistance (7). Elevated adipose tissue expression of TNF-a mRNA has been reported in different rodent models of obesity as well as in clinical studies involving obese patients (23). TNF-a mRNA expression is positively correlated with body adiposity as well as with hyperinsulinemia, showing positive associations with fasting insulin and triglyceride concentrations. TNF-a inhibits the expression of the transcription factor CCAAT/ enhancer binding protein-a (CEBPa) and the nuclear receptor peroxisome proliferator-activated receptor (PPAR)y2 (8,12,14). Furthermore, TNF-a stimulates the nuclear factor- kB transcription factor (NFkB), which orchestrates a series of inflammatory events, including expression of adhesion molecules on the surface of both endothelial cells ...

Stress responses are critical for estrogen (E2) to induce apoptosis in E2-deprived breast cancer cells. Nuclear factor-kappa B (NF-κB) is well known as a therapeutic target to prevent stress responses in chronic inflammatory diseases including cancer. However, whether E2 activates NF-κB to participate in stress-associated apoptosis in E2-deprived breast cancer cells is unclear. We demonstrated that E2 differentially modulates NF-κB activity in E2-deprived breast cancer cells according to the treatment time. Because E2 initially has significant potential to down modulate the NF-κB activation, it completely suppresses the tumor necrosis factor alpha (TNFα)-induced NF-κB activation. We found that E2 preferentially and constantly enhances the expression of transcription factor CCAAT/enhancer binding protein beta (C/EBPβ) which is responsible for suppression of NF-κB activation by E2 in MCF-7:5C cells. The mTOR signaling pathway promotes repression of NF-κB by C/EBPβ which is confirmed by ...
Neutrophil-specific granule deficiency (SGD) is a rare disorder characterized by recurrent pyogenic infections, defective neutrophil chemotaxis and bactericidal activity, and lack of neutrophil secondary granule proteins. It has been linked to a defect in the transcription factor CCAAT/enhancer binding protein (CEBP) epsilon. Recently, loss-of-function mutations in SMARCD2 were identified from SGD patients. SMARCD2 is chromatin-remodeling factor, that interacts with CEBP epsilon ...

ABSTRACT: Fluorescence lifetime imaging microscopy (FLIM) is now routinely used for dynamic measurements of signaling events inside living cells, including detection of protein-protein interactions. An understanding of the basic physics of fluorescence lifetime measurements is required to use this technique. In this protocol, we describe both the time-correlated single photon counting and the frequency-domain methods for FLIM data acquisition and analysis. We describe calibration of both FLIM systems, and demonstrate how they are used to measure the quenched donor fluorescence lifetime that results from F?rster resonance energy transfer. We then show how the FLIM-FRET methods are used to detect the dimerization of the transcription factor CCAAT enhancer binding protein-a in live mouse pituitary cell nuclei. Notably, the factors required for accurate determination and reproducibility of lifetime measurements are described. With either method, the entire protocol including specimen preparation, ...

As an approach to defining the mechanism responsible for activating the expression of these genes, we investigated the binding of nuclear factors to the promoters of two differentiation-induced genes, the 422(aP2) and stearoyl-CoA desaturase 1 (SCD1) genes. DNase I footprinting and gel retardation analysis identified two binding regions within the promoters of each gene that interact with nuclear factors present in differentiated 3T3-L1 adipocytes. ...
In this work, we have shown that the transcription factor C/EBPβ directly regulates the expression of the C3 gene, and that this control could be relevant for the pro-inflammatory effects of this transcription factor. By microarray analysis and RT-PCR we showed that the hippocampal content of C3 transcripts was depleted in C/EBPβ −/− mice. The analysis of the C3 promoter showed that this gene was directly induced by C/EBPβ through a C/EBPβ consensus site located at −616/-599 position from the transcription start site. In accordance with these data, LPS induced the expression of C3 in glial cells, at least in part, through the induction of C/EBPβ since the repression of LPS-induction of C/EBPβ by shRNA interference blocked C3 increase. On the contrary, C/EBPβ overexpression by transient transfection induced C3 expression. Additionally, treatment of these cultures with LPS induced the levels of the pro-inflammatory factors IL-1β and COX-2, which were significantly reduced in those ...
CEBPD (C/EBP delta) is a member of the CCAAT-enhancer binding protein (C/EBP) family of transcription factors characterized by a b-Zip domain that mediates dimerization and DNA binding. CEBPD is induced in response to acute stressors such as cytokine stimulation, bacterial lipopolysaccharide (LPS), corticosteroids, radiation and hypoxia. We have previously reported that CEBPD has dual functions in breast cancer by both attenuating or enhancing oncogenic pathways depending on context (Balamurugan and Sterneck, 2013, Mendoza-Villanueva et al., 2016). Recent studies reveal that elevated Endoplasmic Reticulum (ER) stress is associated with the pathology of several diseases including cancer. Limiting supply of nutrients and oxygen in growing tumor cells disrupts the protein folding homeostasis resulting in activation of the unfolded protein response (UPR). The UPR includes pathways that support adaptation to stress, and that are also implicated in promoting malignant features and therapy resistance ...
The transcription factor CCAAT-enhancer-binding protein alpha (C/EBPα) is a master regulator of granulopoiesis and regulates the switch between proliferating, uncommitted progenitors and cell-cycle-arrested, differentiated myeloid cells. Usage of two alternative translation initiation sites in the CEBPA mRNA results in expression of a full-length C/EBPα protein p42 (42 kDa) and a shorter p30 isoform (30 kDa). CEBPA mutations are found in 9-15% of Acute Myeloid Leukemia (AML) patients. N-terminal frameshift mutations in the CEBPA gene lead to selective ablation of p42 expression, while C-terminal mutations disrupt the dimerization and DNA-binding ability of C/EBPα. AML patients harbor either mono- or biallelic CEBPA mutations (CEBPAmo or CEBPAbi) and both genotypes are frequently associated with concurrent mutations in other genes. The most commonly co-occurring mutations in both groups are loss-of-function mutations in the methylcytosine dioxygenase TET2 (44.4% in CEBPAmo / 34.8% in CEBPAbi). ...

Protein kinase C (PKC) is a family of serine- and threonine-specific protein kinases that can be activated by calcium and the second messenger diacylglycerol. PKC family members phosphorylate a wide variety of protein targets and are known to be involved in diverse cellular signaling pathways. PKC family members also serve as major receptors for phorbol esters, a class of tumor promoters. Each member of the PKC family has a specific expression profile and is believed to play a distinct role in cells. The protein encoded by this gene is one of the PKC family members. It is a calcium-independent and phospholipids-dependent protein kinase. It is predominantly expressed in epithelial tissues and has been shown to reside specifically in the cell nucleus. This protein kinase can regulate keratinocyte differentiation by activating the MAP kinase MAPK13 (p38delta)-activated protein kinase cascade that targets CCAAT/enhancer-binding protein alpha (CEBPA). It is also found to mediate the transcription ...

Background The up-regulation of CCAAT/enhancer binding protein delta (CEBPD) has frequently been observed in macrophages in age-associated disorders, including rheumatoid arthritis (RA). However, the role of macrophage CEBPD in the pathogenesis of RA is unclear. Methodology and Principal Findings We found that the collagen-induced arthritis (CIA) score and the number of affected paws in Cebpd−/− mice were significantly decreased compared with the wild-type (WT) mice. The histological analysis revealed an attenuated CIA in Cebpd−/− mice, as shown by reduced pannus formation and greater integrity of joint architecture in affected paws of Cebpd−/− mice compared with WT mice. In addition, immunohistochemistry analysis revealed decreased pannus proliferation and angiogenesis in Cebpd−/− mice compared with WT mice. CEBPD activated in macrophages played a functional role in promoting the tube formation of endothelial cells and the migration and proliferation of synoviocytes. In vivo DNA
CEBPA mutations in patients with de novo acute myeloid leukemia: data analysis in a Chinese population Long Su, SuJun Gao, XiaoLiang Liu, YeHui Tan, Lu Wang, Wei Li Cancer Center, The First Hospital, Jilin University, Changchun, Peoples Republic of China Background: This study was aimed to explore the clinical characteristics and prognoses of acute myeloid leukemia (AML) patients with CEBPA mutations.

Here, we investigated the mechanisms by which PPARδ agonists control expression of 14-3-3ε, a key antiinflammatory protein in endothelial cells.12 Our data not only provide evidence that PPARδ modulates expression of YWHAE gene and 14-3-3ε protein under resting conditions but also demonstrate that this nuclear receptor upregulates 14-3-3ε expression by targeting transcription via a PPRE-independent pathway involving colocalization of C/EBPβ and PPARδ on YWHAE promoter. Several lines of evidence support these conclusions. First, PPARδ agonists regulated YWHAE promoter activity in a concentration- and time-dependent manner. Concordantly, YWHAE promoter was upregulated by PPARδ overexpression, whereas specific PPARγ and PPARα ligands had no effect on YWHAE promoter under our experimental conditions. Second, PPARδ activation increased 14-3-3ε mRNA and protein expression in both primary and spontaneously transformed endothelial cell lines, whereas PPARδ knockdown depressed basal and ...

CCAAT/enhancer binding protein (C/EBP), epsilon, also known as CEBPE and CRP1, is a type of ccaat-enhancer-binding protein. CEBPE is its human gene and is pro-apoptotic. The protein encoded by this gene is a bZIP transcription factor which can bind as a homodimer to certain DNA regulatory regions. It can also form heterodimers with the related protein CEBP-δ. The encoded protein may be essential for terminal differentiation and functional maturation of committed granulocyte progenitor cells. Mutations in this gene have been associated with specific granule deficiency, a rare congenital disorder. Multiple variants of this gene have been described, but the full-length nature of only one has been determined.

Amelogenin gene expression is spatiotemporally regulated during enamel biomineralization. Studies show that C/EBP alpha is a transactivator of the mouse amelogenin gene acting at the C/EBP alpha cis-element located in the -70/+52 minimal promoter that also contains a reversed CCAAT box (-58/-54). Similar to the C/EBP alpha binding site, this CCAAT box is required for the basal promoter activity. Electrophoretic mobility shift assays demonstrate that NF-Y is directly bound to this reversed CCAAT box. Co-transfection of C/EBP alpha and NF-Y synergistically increases the promoter activity. Protein-protein interactions between C/EBP alpha with NF-Y are identified by a co-immunoprecipitation analysis.; A protein/DNA array technique is utilized to identify a transcriptional factor named YY1. YY1 represses both the basal amelogenin promoter activity and C/EBP alpha-mediated transactivation. Furthermore, YY1 repression is independent of its DNA binding capacity.; C/EBP alpha contains four highly ...

Chronic pain is increasingly recognized as an important comorbidity of HIV-infected patients, however, the exact molecular mechanisms of HIV-related pain are still elusive. CCAAT/enhancer binding proteins (C/EBPs) are expressed in various tissues, including the central nervous system. C/EBPβ, one of C/EBPs is involved in the progression of HIV/AIDS, but the exact role of C/EBPβ and its upstream factors are not clear in HIV pain state. Here, we used a neuropathic pain model of perineural HIV envelope glycoprotein gp120 application onto the rat sciatic nerve to test the role of phosphorylated C/EBPβ (pC/EBPβ) and its upstream pathway in the spinal cord dorsal horn (SCDH ...
Adipocytes play an important role in energy storage and metabolism. Adipocyte differentiation is a developmental process that is critical for metabolic homeostasis and nutrient signaling. It is controlled by complex actions involving gene expression and signal transduction. Preadipocytes are present throughout adult life in adipose tissues and can proliferate and differentiate into mature adipocytes according to the energy balance. The proliferation and differentiation of these preadipocytes contribute to increases in adipose tissue mass. In vitro study indicates that different tissue-derived preadipocytes exhibit differently in lipid accumulation, adipogenic transcription factor expression, and TNF?-induced apoptosis. It has also been demonstrated that there is a close relationship between adipocyte differentiation and many physiological and pathological processes including fat metabolism, energy balance, obesity, diabetes, hyperlipidemia and breast cancer.

The retinoblastoma protein (RB) has previously been shown to facilitate adipocyte differentiation by inducing cell cycle arrest and enhancing the transactivation by the adipogenic CCAAT/enhancer binding proteins (C/EBP). We show here that the peroxisome proliferator-activated receptor gamma (PPARgamma), a nuclear receptor pivotal for adipogenesis, promotes adipocyte differentiation more efficiently in the absence of RB. PPARgamma and RB were shown to coimmunoprecipitate, and this PPARgamma-RB complex also contains the histone deacetylase HDAC3, thereby attenuating PPARgammas capacity to drive gene expression and adipocyte differentiation. Dissociation of the PPARgamma-RB-HDAC3 complex by RB phosphorylation or by inhibition of HDAC activity stimulates adipocyte differentiation. These observations underscore an important function of both RB and HDAC3 in fine-tuning PPARgamma activity and adipocyte differentiation.. Keywords: Thiazolidinediones. ...

Another study applying ChIP-seq for two different TFs (CCAAT/enhancer-binding protein α and hepatocyte nuclear factor 4 α) in the livers of five vertebrates species provides an alternative view of conservation of TF-binding events (Schmidt et al., 2010). This work demonstrated that the majority of binding events are species specific, rather than consistently localized in conserved regions. Binding to conserved sequences in one species was rarely indicative of binding to the homologous sequence in others. These differences in binding were consistently observed between human and mouse in the livers of both species, and also in the livers of aneuploid mice harbouring human chromosome 21. Binding to the human chromosome in mouse was representative of binding to the endogenous chromosome in human, rather than binding to mouse chromosomes (Wilson et al., 2008) (Fig. 4). The differences in binding between species are therefore unlikely to be due to non-equivalence in the assayed tissue. Similarly, ...

Chorion-specific transcription factor GCMa is a protein that, in humans, is encoded by the GCM1 gene. This gene encodes a DNA-binding protein with a gcm-motif (glial cell missing motif). The encoded protein is a homolog of the Drosophila glial cells missing gene (gcm). This protein binds to the GCM-motif (A/G)CCCGCAT, a novel sequence among known targets of DNA-binding proteins.

DNA-binding proteins from starved cells (DPS) are proteins that belong to the ferritin superfamily and are characterized by strong similarities but also distinctive differences with respect to "canonical" ferritins. DPS proteins are part of a complex bacterial defence system that protects DNA against oxidative damage and are distributed widely in the bacterial kingdom. DPS are highly symmetrical dodecameric proteins of 200 kDa characterized from a shell-like structure of 2:3 tetrahedral symmetry assembled from identical subunits with an external diameter of ~ 9 nm and a central cavity of ~ 4.5 nm in diameter. Dps proteins belong to the ferritin superfamily and the DNA protection is afforded by means of a double mechanism: The first was discovered in Escherichia coli Dps in 1992 and has given the name to the protein family; during stationary phase, Dps binds the chromosome non-specifically, ...
... is a method of investigating the sequence specificity of DNA-binding proteins in vitro. This technique can be used to study protein-DNA interactions both outside and within cells. The regulation of transcription has been studied extensively, and yet there is still much that is not known. Transcription factors and associated proteins that bind promoters, enhancers, or silencers to drive or repress transcription are fundamental to understanding the unique regulation of individual genes within the genome. Techniques like DNA footprinting help elucidate which proteins bind to these associated regions of DNA and unravel the complexities of transcriptional control. In 1978, David Galas and Albert Schmitz developed the DNA footprinting technique to study the binding specificity of the lac repressor protein. It was originally a modification of the Maxam-Gilbert chemical ...
... ting, based along the lines of Southern blotting (which was created by Edwin Southern) and first described by B. Bowen, J. Steinberg and colleagues in 1980, is a lab technique which involves identifying and characterizing DNA-binding proteins (proteins that bind to DNA) by their ability to bind to specific oligonucleotide probes. The proteins are separated by gel electrophoresis and are subsequently transferred to nitrocellulose membranes similar to other types of blotting. The name southwestern blotting is based on the fact that this technique detects DNA-binding proteins, since DNA detection is by Southern blotting and protein detection is by western blotting. However, since the first southwestern blottings, many more have been proposed and discovered. The former protocols were hampered by the need for large amounts of proteins and their susceptibility to degradation ...
Transcriptional enhancer factor TEF-1 also known as TEA domain family member 1 (TEAD1) and transcription factor 13 (TCF-13) is a protein that in humans is encoded by the TEAD1 gene. TEAD1 was the first member of the TEAD family of transcription factors to be identified. All members of the TEAD family share a highly conserved DNA binding domain called the TEA domain. This DNA binding domain has a consensus DNA sequence 5'-CATTCCA/T-3' that is called the MCAT element. The three dimensional structure of the TEA domain has been identified [5]. Its conformation is close to that of the homeodomain and contains 3 α helixes (H1, H2 and H3). It is the H3 helix that enables TEAD proteins to bind DNA. Another conserved domain of TEAD1 is located at the C terminus of the protein. It allows the binding of cofactors and has been called the YAP1 binding domain, because it is its ability to ...
... (ETF, ETEF-1, TEF-4), together with TEAD1, defined a novel family of transcription factors, the TEAD family, highly conserved through evolution. TEAD proteins were notably found in Drosophila (Scalloped), C. elegans (egl -44), S. Cerevisiae and A. nidulans. TEAD2 has been less studied than TEAD1 but a few studies revealed its role during development. TEAD2 is a member of the mammalian TEAD transcription factor family (initially named the transcriptional enhancer factor (TEF) family), which contain the TEA/ATTS DNA-binding domain. Members of the family in mammals are TEAD1, TEAD2, TEAD3, TEAD4. TEAD2 is selectively expressed in a subset of embryonic tissues including the cerebellum, testis, and distal portions of the forelimb and hindlimb buds, as well as the tail bud, but it is essentially absent from adult tissues. TEAD2 has also been shown to be expressed very early during development, i.e. from the 2-cell stage. TEAD proteins are ...
Nuclear factor NF-kappa-B p105 subunit is a protein that in humans is encoded by the NFKB1 gene. This gene encodes a 105 kD protein which can undergo cotranslational processing by the 26S proteasome to produce a 50 kD protein. The 105 kD protein is a Rel protein-specific transcription inhibitor and the 50 kD protein is a DNA binding subunit of the NF-kappaB (NF-κB) protein complex. NF-κB is a transcription factor that is activated by various intra- and extra-cellular stimuli such as cytokines, oxidant-free radicals, ultraviolet irradiation, and bacterial or viral products. Activated NF-κB translocates into the nucleus and stimulates the expression of genes involved in a wide variety of biological functions; over 200 known genes are targets of NF-κB in various cell types, under specific conditions. Inappropriate activation of NF-κB has been associated with a number of ...
