CCAAT-Enhancer-Binding Protein-alpha
A CCAAT-enhancer-binding protein found in LIVER; ADIPOSE TISSUE; INTESTINES; LUNG; ADRENAL GLANDS; PLACENTA; OVARY and peripheral blood mononuclear cells (LEUKOCYTES, MONONUCLEAR). 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.

3T3 Cells
Cell lines whose original growing procedure consisted being transferred (T) every 3 days and plated at 300,000 cells per plate (J Cell Biol 17:299-313, 1963). 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.

Transfection
Electrophoretic Mobility Shift Assay
An electrophoretic technique for assaying the binding of one compound to another. Typically one compound is labeled to follow its mobility during electrophoresis. If the labeled compound is bound by the other compound, then the mobility of the labeled compound through the electrophoretic medium will be retarded.

Adipose Tissue
Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.

Gene Expression
Cell Nucleus
Within a eukaryotic cell, a membrane-limited body which contains chromosomes and one or more nucleoli (CELL NUCLEOLUS). The nuclear membrane consists of a double unit-type membrane which is perforated by a number of pores; the outermost membrane is continuous with the ENDOPLASMIC RETICULUM. 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
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
Chromatin Immunoprecipitation
A technique for identifying specific DNA sequences that are bound, in vivo, to proteins of interest. It involves formaldehyde fixation of CHROMATIN to crosslink the DNA-BINDING PROTEINS to the DNA. After shearing the DNA into small fragments, specific DNA-protein complexes are isolated by immunoprecipitation with protein-specific ANTIBODIES. Then, the DNA isolated from the complex can be identified by PCR amplification and sequencing.

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.

Leucine Zippers
DNA-binding motifs formed from two alpha-helixes which intertwine for about eight turns into a coiled coil and then bifurcate to form Y shaped structures. Leucines occurring in heptad repeats end up on the same sides of the helixes and are adjacent to each other in the stem of the Y (the "zipper" region). The DNA-binding residues are located in the bifurcated region of the Y.

Receptors, Cytoplasmic and Nuclear
Intracellular receptors that can be found in the cytoplasm or in the nucleus. They bind to extracellular signaling molecules that migrate through or are transported across the CELL MEMBRANE. Many members of this class of receptors occur in the cytoplasm and are transported to the CELL NUCLEUS upon ligand-binding where they signal via DNA-binding and transcription regulation. Also included in this category are receptors found on INTRACELLULAR MEMBRANES that act via mechanisms similar to CELL SURFACE RECEPTORS.

Glucocorticoids
A group of CORTICOSTEROIDS that affect carbohydrate metabolism (GLUCONEOGENESIS, liver glycogen deposition, elevation of BLOOD SUGAR), inhibit ADRENOCORTICOTROPIC HORMONE secretion, and possess pronounced anti-inflammatory activity. They also play a role in fat and protein metabolism, maintenance of arterial blood pressure, alteration of the connective tissue response to injury, reduction in the number of circulating lymphocytes, and functioning of the central nervous system.
Oligonucleotides
Mutagenesis, Site-Directed
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.
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. They also exhibit phagocytic activity and responsiveness to chemotactic stimuli. (From Hay et al., American Type Culture Collection, 7th ed, pp127-8)

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.

A system of cisternae in the CYTOPLASM of many cells. In places the endoplasmic reticulum is continuous with the plasma membrane (CELL MEMBRANE) or outer membrane of the nuclear envelope. If the outer surfaces of the endoplasmic reticulum membranes are coated with ribosomes, the endoplasmic reticulum is said to be rough-surfaced (ENDOPLASMIC RETICULUM, ROUGH); otherwise it is said to be smooth-surfaced (ENDOPLASMIC RETICULUM, SMOOTH).

Lipopolysaccharides
Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed)
Carcinoma, Hepatocellular
A primary malignant neoplasm of epithelial liver cells. It ranges from a well-differentiated tumor with EPITHELIAL CELLS indistinguishable from normal HEPATOCYTES to a poorly differentiated neoplasm. The cells may be uniform or markedly pleomorphic, or form GIANT CELLS. Several classification schemes have been suggested.

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.
