Basic Helix-Loop-Helix Transcription Factors
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.
Transcription Factor AP-1
Forkhead Transcription Factors
Gene Expression Regulation, Developmental
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.
Amino Acid Sequence
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).
Basic-Leucine Zipper Transcription Factors
Transcription Factor AP-2
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)

The level of protein structure in which combinations of secondary protein structures (alpha helices, beta sheets, loop regions, and motifs) pack together to form folded shapes called domains. Disulfide bridges between cysteines in two different parts of the polypeptide chain along with other interactions between the chains play a role in the formation and stabilization of tertiary structure. Small proteins usually consist of only one domain but larger proteins may contain a number of domains connected by segments of polypeptide chain which lack regular secondary structure.

Transcription Factor TFIIIA
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.

These proteins are transcription factors that control developmental pathways. The prototype of this family is the mouse Brachyury (or T) gene product.
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.

Early Growth Response Protein 1
Sequence Homology, Nucleic Acid
A gene silencing phenomenon whereby specific dsRNAs (RNA, DOUBLE-STRANDED) trigger the degradation of homologous mRNA (RNA, MESSENGER). The specific dsRNAs are processed into SMALL INTERFERING RNA (siRNA) which serves as a guide for cleavage of the homologous mRNA in the RNA-INDUCED SILENCING COMPLEX. DNA METHYLATION may also be triggered during this process.
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.

(Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
Sequence Analysis, DNA
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 species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc.
Twist Transcription Factor
NF-E2 Transcription Factor, p45 Subunit
An enzyme that catalyzes the acetylation of chloramphenicol to yield chloramphenicol 3-acetate. Since chloramphenicol 3-acetate does not bind to bacterial ribosomes and is not an inhibitor of peptidyltransferase, the enzyme is responsible for the naturally occurring chloramphenicol resistance in bacteria. The enzyme, for which variants are known, is found in both gram-negative and gram-positive bacteria. EC 188.8.131.52.
Gene Expression Regulation, Viral
Proto-Oncogene Proteins c-fos
Cellular DNA-binding proteins encoded by the c-fos genes (GENES, FOS). They are involved in growth-related transcriptional control. c-fos combines with c-jun (PROTO-ONCOGENE PROTEINS C-JUN) to form a c-fos/c-jun heterodimer (TRANSCRIPTION FACTOR AP-1) that binds to the TRE (TPA-responsive element) in promoters of certain genes.

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.
CELL LINES derived from the CV-1 cell line by transformation with a replication origin defective mutant of SV40 VIRUS, which codes for wild type large T antigen (ANTIGENS, POLYOMAVIRUS TRANSFORMING). They are used for transfection and cloning. (The CV-1 cell line was derived from the kidney of an adult male African green monkey (CERCOPITHECUS AETHIOPS).)

Interleukin-12 induces expression of interferon regulatory factor-1 via signal transducer and activator of transcription-4 in human T helper type 1 cells. (1/357)IRF-1-deficient mice show a striking defect in the development of T helper 1 (Th1) cells. In the present report, we investigate the expression of IRF-1 during differentiation of human T helper cells. No significant differences of IRF-1 mRNA expression were found in established Th1 and Th2 cells; however, interleukin 12 (IL-12) induced a strong up-regulation of IRF-1 transcripts in Th1 but not in Th2 cells. We demonstrate that IL-12-induced up-regulation of IRF-1 is mediated by signal transducer and activator of transcription-4, which binds to the interferon (IFN)-gamma-activated sequence present in the promoter of the IRF-1 gene. Strong IL-12-dependent activation of a reporter gene construct containing the IRF-1 IFN-gamma-activated sequence element provides further evidence for the key role of signal transducer and activator of transcription-4 in the IL-12-induced up-regulation of IRF-1 transcripts in T cells. IRF-1 expression was strongly induced after stimulation of naive CD4(+) T cells via the T cell receptor, irrespective of the cytokines present at priming, indicating that this transcription factor does not play a major role in initiating a Th1-specific transcriptional cascade in differentiating helper T cells. However, our finding that IRF-1 is a target gene of IL-12 suggests that some of the IL-12-induced effector functions of Th1 cells may be mediated by IRF-1. (+info)
Homocysteine-induced endoplasmic reticulum stress and growth arrest leads to specific changes in gene expression in human vascular endothelial cells. (2/357)Alterations in the cellular redox potential by homocysteine promote endothelial cell (EC) dysfunction, an early event in the progression of atherothrombotic disease. In this study, we demonstrate that homocysteine causes endoplasmic reticulum (ER) stress and growth arrest in human umbilical vein endothelial cells (HUVEC). To determine if these effects reflect specific changes in gene expression, cDNA microarrays were screened using radiolabeled cDNA probes generated from mRNA derived from HUVEC, cultured in the absence or presence of homocysteine. Good correlation was observed between expression profiles determined by this method and by Northern blotting. Consistent with its adverse effects on the ER, homocysteine alters the expression of genes sensitive to ER stress (ie, GADD45, GADD153, ATF-4, YY1). Several other genes observed to be differentially expressed by homocysteine are known to mediate cell growth and differentiation (ie, GADD45, GADD153, Id-1, cyclin D1, FRA-2), a finding that supports the observation that homocysteine causes a dose-dependent decrease in DNA synthesis in HUVEC. Additional gene profiles also show that homocysteine decreases cellular antioxidant potential (glutathione peroxidase, NKEF-B PAG, superoxide dismutase, clusterin), which could potentially enhance the cytotoxic effects of agents or conditions known to cause oxidative damage. These results successfully demonstrate the use of cDNA microarrays in identifying homocysteine-respondent genes and indicate that homocysteine-induced ER stress and growth arrest reflect specific changes in gene expression in human vascular EC.

Middle T antigen activation of signal transduction pathways does not overcome p53-mediated growth arrest. (3/357)Polyomavirus middle T antigen does not overcome p53-mediated G(1) arrest in mouse embryo fibroblasts. Middle T antigen still associates with the signaling molecules phosphatidylinositol 3-kinase and SHC and activates the transcriptional activity of c-Myc and AP1 in p53-arrested cells. Examination of cell cycle regulatory proteins indicated that p53 does not interfere with these mitogenic signals but acts later in the G(1) phase of the cell cycle. (+info)
Heregulin induces expression, DNA binding activity, and transactivating functions of basic leucine zipper activating transcription factor 4. (4/357)Heregulin beta1 (HRG), a combinatorial ligand for human epidermal growth factor receptor 3 and human epidermal growth factor receptor 4 receptors, is a regulatory secretory polypeptide with distinct biological effects such as growth stimulation, differentiation, invasiveness, and migration in breast cancer cells. The mechanism underlying the diverse functions of HRG is not well established, but it is believed to be dependent on the induced changes in expression of specific cellular gene products, their modification, or both. The binding of basic leucine zipper transcription factors to the cAMP response element is known to activate a variety of gene products with a role or roles in growth regulation. In the studies presented here, we identified basic leucine zipper activating transcription factor (ATF) 4 as one of the HRG-inducible gene product. We demonstrated that HRG stimulation of human cancer cells induces expression of ATF4 mRNA and protein, ATF4 DNA binding activity, and ATF4 transactivating function. Consistent with its role as a transcriptional activator, HRG-stimulated ATF4 protein stimulated the transcription from an artificial promoter with three tandem ATF sites or from a naturally occurring promoter with ATF4 sites such as E-selectin. We also demonstrated a preferential role of the HRG-stimulated mitogen-activated protein kinase pathway, but not the phosphatidylinositol 3'-kinase pathway, in supporting the observed increase in ATF4 DNA binding activity and transcription from E-selectin promoter in HRG-stimulated cells. Because ATF4 binding sites are present in a variety of growth-regulating cellular genes, these findings suggest that the stimulation of ATF4 expression and its transactivating functions may constitute an important mechanism of HRG-mediated regulation of putative genes with diversified functions. The present study is the first demonstration of regulation of expression and transactivation ability of ATF4 by any polypeptide growth factor. (+info)
Identification and characterization of basal and cyclic AMP response elements in the promoter of the rat GTP cyclohydrolase I gene. (5/357)5812 base pairs of rat GTP cyclohydrolase I (GTPCH) 5'-flanking region were cloned and sequenced, and the transcription start site was determined for the gene in rat liver. Progressive deletion analysis using transient transfection assays of luciferase reporter constructs defined the core promoter as a highly conserved 142-base pair GC-rich sequence upstream from the cap site. DNase I footprint analysis of this region revealed (5' --> 3') a Sp1/GC box, a noncanonical cAMP-response element (CRE), a CCAAT-box, and an E-box. Transcription from the core promoter in PC12 but not C6 or Rat2 cells was enhanced by incubation with 8-bromo-cyclic AMP. Mutagenesis showed that both the CRE and CCAAT-box independently contribute to basal and cAMP-dependent activity. The combined CRE and CCAAT-box cassette was also found to enhance basal transcription and confer cAMP sensitivity on a heterologous minimal promoter. The addition of the Sp1/GC box sequence to this minimal promoter construct inhibited basal transcription without affecting the cAMP response. EMSA showed that nuclear proteins from PC12 but not C6 or Rat2 cells bind the CRE as a complex containing activating transcription factor (ATF)-4 and CCAAT enhancer-binding protein beta, while both PC12 and C6 cell nuclear extracts were recruited by the CCAAT-box as a complex containing nuclear factor Y. Overexpression of ATF-4 in PC12 cells was found to transactivate the GTPCH promoter response to cAMP. These studies suggest that the elements required for cell type-specific cAMP-dependent enhancement of gene transcription are located along the GTPCH core promoter and include the CRE and adjacent CCAAT-box and the proteins ATF-4, CCAAT enhancer-binding protein beta, and nuclear factor Y.

Molecular interactions involved in the transactivation of the human T-cell leukemia virus type 1 promoter mediated by Tax and CREB-2 (ATF-4). (6/357)The human T-cell leukemia virus type 1 (HTLV-1) Tax protein activates viral transcription through three 21-bp repeats located in the U3 region of the HTLV-1 long terminal repeat and called Tax-responsive elements (TxREs). Each TxRE contains nucleotide sequences corresponding to imperfect cyclic AMP response elements (CRE). In this study, we demonstrate that the bZIP transcriptional factor CREB-2 is able to bind in vitro to the TxREs and that CREB-2 binding to each of the 21-bp motifs is enhanced by Tax. We also demonstrate that Tax can weakly interact with CREB-2 bound to a cellular palindromic CRE motif such as that found in the somatostatin promoter. Mutagenesis of Tax and CREB-2 demonstrates that both N- and C-terminal domains of Tax and the C-terminal region of CREB-2 are required for direct interaction between the two proteins. In addition, the Tax mutant M47, defective for HTLV-1 activation, is unable to form in vitro a ternary complex with CREB-2 and TxRE. In agreement with recent results suggesting that Tax can recruit the coactivator CREB-binding protein (CBP) on the HTLV-1 promoter, we provide evidence that Tax, CREB-2, and CBP are capable of cooperating to stimulate viral transcription. Taken together, our data highlight the major role played by CREB-2 in Tax-mediated transactivation. (+info)
Functional analysis of the OCA-B promoter. (7/357)OCA-B was identified as a B cell-specific coactivator that functions with either Oct-1 or Oct-2 to mediate efficient cell type-specific transcription via the octamer site (ATGCAAAT) both in vivo and in vitro. Mice lacking OCA-B exhibit normal Ag-independent B cell maturation. In contrast, Ag-dependent functions, including production of secondary Ig isotypes and germinal center formation, are greatly affected. To better understand OCA-B expression and, ultimately, the defects observed in the OCA-B knockout mice, we have cloned the OCA-B promoter and examined its function in both transformed and primary B cells. We show here that the OCA-B promoter is developmentally regulated, with activity increasing throughout B cell differentiation. Through physical and functional assays, we have found an activating transcription factor/cAMP response element binding protein binding site (or cAMP response element) that is crucial for OCA-B promoter activity. Furthermore, we demonstrate that IL-4 and anti-CD40 induce both the OCA-B promoter and octamer-dependent promoters, thus implicating OCA-B in B cell signaling events in the nucleus. (+info)
The cryptocephal gene (ATF4) encodes multiple basic-leucine zipper proteins controlling molting and metamorphosis in Drosophila. (8/357)The cryptocephal (crc) mutation causes pleiotropic defects in ecdysone-regulated events during Drosophila molting and metamorphosis. Here we report that crc encodes a Drosophila homolog of vertebrate ATF4, a member of the CREB/ATF family of basic-leucine zipper (bZIP) transcription factors. We identified three putative protein isoforms. CRC-A and CRC-B contain the bZIP domain, and CRC-D is a C-terminally truncated form. We have generated seven new crc alleles. Consistent with the molecular diversity of crc, these alleles show that crc is a complex genetic locus with two overlapping lethal complementation groups. Alleles representing both groups were rescued by a cDNA encoding CRC-B. One lethal group (crc(1), crc(R6), and crc(Rev8)) consists of strong hypomorphic or null alleles that are associated with mutations of both CRC-A and CRC-B. These mutants display defects associated with larval molting and pupariation. In addition, they fail to evert the head and fail to elongate the imaginal discs during pupation, and they display variable defects in the subsequent differentiation of the adult abdomen. The other group (crc(R1), crc(R2), crc(E85), crc(E98), and crc(929)) is associated with disruptions of CRC-A and CRC-D; except for a failure to properly elongate the leg discs, these mutants initiate metamorphosis normally. Subsequently, they display a novel metamorphic phenotype, involving collapse of the head and abdomen toward the thorax. The crc gene is expressed throughout development and in many tissues. In third instar larvae, crc expression is high in targets of ecdysone signaling, such as the leg and wing imaginal discs, and in the ring gland, the source of ecdysone. Together, these findings implicate CREB/ATF proteins in essential functions during molting and metamorphosis. In addition, the similarities between the mutant phenotypes of crc and the ecdysone-responsive genes indicate that these genes are likely to be involved in common signaling pathways. (+info)

Good points Marianne. I might also add that not all IOIs are what they may seem. For example, hair twirling can occur when a woman feels uncomfortable/stressed. If it is slow and methodical its probably an IOI. If it is fast paced and kind of a tugging action, she is having a negative reaction and feels uncomfortable/stressed. Same goes for stroking actions. Pay attention to the pace. If it is slow and rhythmic she is probably daydreaming/thinking erotic thoughts. If it is fast paced, she is probably anxious/uncomfortable/stressed ...
10 Be surface exposure dating of the last deglaciation in the Aare Valley, Switzerland | SpringerLink
The combined Rhone and Aare Glaciers presumably reached their last glacial maximum (LGM) extent on the Swiss Plateau prior to 24 ka. Two well-preserved, less extensive moraine stades, the Gurten and Bern Stade, document the last deglaciation of the Aare Valley, yet age constraints are very scarce. In order to establish a more robust chronology for the glacial/deglacial history of the Aare Valley, we applied 10Be surface exposure dating on eleven boulders from the Gurten and Bern Stade. Several exposure ages are of Holocene age and likely document post-depositional processes, including boulder toppling and quarrying. The remaining exposure ages, however yield oldest ages of 20.7 ± 2.2 ka for the Gurten Stade and 19.0 ± 2.0 ka for the Bern Stade. Our results are in good agreement with published chronologies from other sites in the Alps.

Amino acid limitation regulates CHOP expression through a specific pathway independent of the unfolded protein response
The gene encoding CHOP (C/EBP-homologous protein) is transcriptionally activated by many stimuli and by amino acid deprivation. CHOP induction was considered to be due to an accumulation of unfolded protein into the ER (unfolded protein response (UPR)). We investigate the role of the UPR in the indu …

ATF Boss Threatens Whistleblowers
Choices and consequences means simply that if you make poor choices, that if you dont abide by the rules, that if you dont respect the chain of command, if you dont find the appropriate way to raise your concerns to your leadership, there will be consequences, because we cannot tolerate - we cannot tolerate - an undisciplined organization, he said.. Sen. Charles Grassley, R-Iowa., and Rep. Darrell Issa, R-Calif., sent a letter Wednesday to Jones declaring the message could be interpreted as a threat and asked him to clarify.. Your ominous message - which could be interpreted as a threat - is likely to have a major chilling effect on ATF employees exercising their rights to contact Congress, they wrote.. What it appears to be is a not-so-veiled threat telling (ATF employees) not to do what they did to expose Fast and Furious, Issa said. Hes basically saying no, keep it in the chain.. The ATF insists the video (above) was taken out of context.. It was directed at employees who ...

ATF6, a membrane-anchored transcription factor from the endoplasmic reticulum (ER) that modulates the cellular response to stress as an effector of the unfolded-protein response (UPR), is a key player in the development of tumors of different origin. reticulum (ER) can be particularly affected by the presence of mutations in secretory proteins or by dynamic changes in the cellular microenvironment, events which are often encountered in cancers. In the ER, these events are sensed by specific sensors, which in turn trigger select Rabbit Polyclonal to CPB2 signaling pathways, collectively named the unfolded-protein response (UPR) (1). The UPR is an adaptive response that allows the cells to either overcome the stress or promote cell death in the case of overwhelming burden (1). Three ER-resident proteins, namely, the protein kinase PKR-like ER kinase (PERK), the inositol-requiring protein 1 alpha (IRE1), and the activating transcription factor 6 alpha (ATF6), have been identified as the major ...
ATFs Warning to Whistleblowers - Washington Free Beacon
Some lawmakers and government accountability groups interpreted the words as a warning to employees considering blowing the whistle on corruption.. In a July 18 letter to Jones, Rep. Darrell Issa (R., Calif.) and Sen. Chuck Grassley (R., Iowa) wrote ATF employees must be free and clear of agency interference or retaliation if they choose to talk to Congress.. Your ominous message-which could be interpreted as a threat-is likely to have a major chilling effect on ATF employees exercising their rights to contact Congress, the two lawmakers wrote. Therefore, it needs to be clarified.. On numerous occasions, we have stressed to ATF and the Department of Justice the importance of protecting whistleblower disclosures and preventing retaliation against whistleblowers, they continued.. The bureau needs to make up its mind whether its going to be supportive of employees trying to get its mission back on track, or if its going to snuff out dissent, said Tom Devine, the legal director of the ...

FIG. 6. Transcription and translation of ATF3 mRNA is not dependent on Perk activity during hypoxia. (A) ATF3 total mRNA expression is induced by hypoxic stress. Total RNA was isolated prior to sucrose gradient fractionation from hypoxia-treated (4 h) or normoxic (0 h) SV40-immortalized Perk+/+ and Perk−/− cells, reverse transcribed, and quantified by real-time PCR. The quantities of each transcript are described as the number of transcripts isolated per microgram of total RNA. Each sample was independently normalized to a spiked internal control. Q-PCR analysis was replicated in triplicate. Results are representative of the averages ± SEM for three independent experiments. (B) ATF3 transcripts are enriched in the polysomes of Perk+/+ and Perk−/− cells during hypoxia. High-molecular-weight polysomes from hypoxia-treated (4 h) or normoxic (0 h) SV40-immortalized Perk+/+ and Perk−/− cells were pooled (fractions 6 to 10), reverse transcribed, and quantified by real-time PCR.
