results suggest a conditional regulation of KRT16 gene by ATF4 that may be inhibited in normal cells, but engaged during cancer progression. Potential roles of KRT16, FAM129A and HKDC1 genes upregulation in adaptive stress responses and pathologies are discussed
Results provide evidence that the availability of glucose controls ATF4-mediated MITF (show MITF Antibodies) suppression to drive melanoma cell proliferation.
Decreased ATF4 expression as a mechanism of acquired resistance to long-term amino acid limitation in cancer cells
These results suggest that p21 (show CDKN1A Antibodies) induction plays a vital role in the cellular response to ER stress and indicate that p21 (show CDKN1A Antibodies) is a prosurvival effector of ATF4.
GRP78 (show HSPA5 Antibodies) inhibition enhances ATF4-induced cell death by the deubiquitination and stabilization of CHOP (show DDIT3 Antibodies) in human osteosarcoma cells.
Expression of either dominant-negative or constitutively active mutants of Nrf2 (show GABPA Antibodies), ATF4, or c-Jun (show JUN Antibodies) confirmed that distinct transcription units are regulated by these transcription factors.
ATF4 contributes to tumor growth of endometrial cancer (EC) by promoting CCL2 (show CCL2 Antibodies) and subsequent recruitment of macrophage, and ATF4/CCL2 (show CCL2 Antibodies) axis might be a potential therapeutic target for EC.
ATF4 expression fosters the malignancy of primary brain tumors and increases proliferation and tumor angiogenesis; experiments revealed that ATF4-dependent tumor promoting effects are mediated by transcriptional targeting the glutamate (show GRIN1 Antibodies) antiporter xCT (show SLC7A11 Antibodies)
The PERK (show EIF2AK3 Antibodies)-eIF2alpha (show EIF2A Antibodies)-ATF4-CHOP (show DDIT3 Antibodies) signaling pathway has a critical role in tumor progression during endoplasmic reticulum stress. (Review)
ATF4 pathway is activated in vivo upon mitochondrial stress.
HIV/SIV exploits the early host antiviral response through GCN2 (show EIF2AK4 Antibodies)-ATF4 signaling by utilizing ATF4 for activating the viral LTR transcription to establish initial viral replication
expression levels of porcine ATF4 gene were up-regulated 60 days and 120 days after birth in both breeds and the expression level in Meishan pigs was obviously higher than that in Large White pigs
Tissue transcription analysis revealed that both porcine CREB2 (show ATF2 Antibodies) and CREB3 (show CREB3 Antibodies) mRNA were ubiquitously detected in all examined tissues.
Over-expression of atf4 in embryos interferes with neurogenesis and eye formation.
Unlike other CREB2 (ATF4) proteins, the ATF4 isolated from the gonads of Xenopus embryos contains a consensus phosphorylation site for protein kinase A (PKA).

We hypothesize that the essential role of methionine-charged initiator tRNA in forming ternary complex is responsible for the robust ability of methionine deficiency to induce ATF4 and the ISR even in the absence of GCN2 (show EIF2AK4 Antibodies) or eIF2alpha (show EIF2A Antibodies) kinase activity.

Transcriptional profiling reveals that mouse neuroblastoma (show ARHGEF16 Antibodies) sphere-forming cells acquire a metabolic program characterized by transcriptional activation of the cholesterol and serine-glycine synthesis pathways, primarily as a result of increased expression of sterol regulatory element binding factors and Atf4, respectively
MIF-2 (show HSPA5 Antibodies)/D-DT is an early response cytokine in the I/R injury repair of the proximal tubule, enhancing regeneration through SLPI (show SLPI Antibodies)- and ATF4-dependent mechanisms.
ATF4 has a role in gene expression during basal conditions, with 385 genes altered by the loss of ATF4 in the absence of apparent stress. Deletion of ATF4 alters genes that are required for the conversion of cholesterol to bile acid (CYP7A1 (show CYP7A1 Antibodies)), esterification of cholesterol (SOAT2 (show SOAT2 Antibodies)), and transport from the hepatocyte (ABCA1 (show ABCA1 Antibodies)); when ATF4 loss is coupled with ER stress, results in increase in free cholesterol within hepatocyte
Data, including data from studies using cells from knockout mice, suggest that gasotransmitter H(2)S up-regulates eIF2a (show EIF2A Antibodies) phosphorylation by inhibiting PPP1CA (show PPP1CA Antibodies) via persulfidation, which in turn leads to transient suppression of global translation and activation of Atf4 expression. (eIF2a (show EIF2A Antibodies) = eukaryotic initiation factor-2alpha (show EIF2S1 Antibodies); PPP1CA (show PPP1CA Antibodies) = protein phosphatase 1 catalytic subunit alpha; Atf4 = activating transcription factor 4)
This gene encodes a transcription factor that was originally identified as a widely expressed mammalian DNA binding protein that could bind a tax-responsive enhancer element in the LTR of HTLV-1. The encoded protein was also isolated and characterized as the cAMP-response element binding protein 2 (CREB-2). The protein encoded by this gene belongs to a family of DNA-binding proteins that includes the AP-1 family of transcription factors, cAMP-response element binding proteins (CREBs) and CREB-like proteins. These transcription factors share a leucine zipper region that is involved in protein-protein interactions, located C-terminal to a stretch of basic amino acids that functions as a DNA binding domain. Two alternative transcripts encoding the same protein have been described. Two pseudogenes are located on the X chromosome at q28 in a region containing a large inverted duplication.
