Hepatocyte nuclear factor 4, alpha

TCF, HNF4alpha, HNF-4, MODY, hepatocyte nuclear factor 4alpha
The protein encoded by this gene is a nuclear transcription factor which binds DNA as a homodimer. The encoded protein controls the expression of several genes, including hepatocyte nuclear factor 1 alpha, a transcription factor which regulates the expression of several hepatic genes. This gene may play a role in development of the liver, kidney, and intestines. Mutations in this gene have been associated with monogenic autosomal dominant non-insulin-dependent diabetes mellitus type I. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Jul 2008] (from NCBI)

Sox2 Acts in a Dose-Dependent Fashion to Regulate Proliferation of Cortical Progenitors.
Muhr et al., Stockholm, Sweden. In Cell Rep, 03 Jan 2015

Epigenome-Guided Analysis of the Transcriptome of Plaque Macrophages during Atherosclerosis Regression Reveals Activation of the Wnt Signaling Pathway.
Gold et al., Seattle, United States. In Plos Genet, 31 Dec 2014
Of these, the TCF/LEF binding site was present in promoters of upregulated genes related to cell motility, suggesting that the canonical Wnt signaling pathway may be activated in plaque macrophages during regression.

Jiang et al., San Francisco, United States. In J Steroid Biochem Mol Biol, 01 Dec 2014
Whereas, VDR binding to β-catenin may block its activation of TCF/LEF1 sites, β-catenin binding to VDR may enhance its activation of VDREs.
Thyroid tumor formation in the male mouse induced by fluopyram is mediated by activation of hepatic CAR/PXR nuclear receptors.
Bars et al., Antibes, France. In Regul Toxicol Pharmacol, 17 Nov 2014
Furthermore, compelling evidence for Car/Pxr activation being the molecular initiating event for these thyroid tumors was provided by the absence of the sequential key events responsible for the TCF tumors in Car/Pxr KO mice when exposed to fluopyram.
Inhibition of C-terminal Binding Protein attenuates Transcription Factor 4 signaling to selectively target Colon Cancer Stem Cells.
Patel et al., Richmond, United States. In Cell Cycle, Oct 2014
CSCs demonstrated significant upregulation of CtBP1 and CtBP2 levels (mRNA and protein) and activity partly due to increased NADH/NAD ratio, as well as increased TCF/LEF transcriptional activity, compared to respective controls.
TCF-1 and LEF-1 act upstream of Th-POK to promote the CD4(+) T cell fate and interact with Runx3 to silence Cd4 in CD8(+) T cells.
Xue et al., Iowa City, United States. In Nat Immunol, Jul 2014
The transcription factors TCF-1 and LEF-1 are essential for early T cell development, but their roles beyond the CD4(+)CD8(+) double-positive (DP) stage are unknown.
The AGC kinase SGK1 regulates TH1 and TH2 differentiation downstream of the mTORC2 complex.
Powell et al., Baltimore, United States. In Nat Immunol, May 2014
Simultaneously, SGK1 repressed the production of interferon-γ (IFN-γ) by controlling expression of the long isoform of the transcription factor TCF-1.
TERT promoter mutations in cancer development.
Kumar et al., Heidelberg, Germany. In Curr Opin Genet Dev, Feb 2014
The newly described germline and recurrent somatic mutations in melanoma and other cancers in the TERT promoter that create de novo E-twenty six/ternary complex factors (Ets/TCF) binding sites, provide an insight into the possible cause of tumor-specific increased TERT expression.
Oncogenic mechanisms in Burkitt lymphoma.
Staudt et al., Bethesda, United States. In Cold Spring Harb Perspect Med, Feb 2014
The transcription factor TCF-3 is central to Burkitt lymphoma pathogenesis.
Role and regulation of β-catenin signaling during physiological liver growth.
Monga, Pittsburgh, United States. In Gene Expr, Dec 2013
Such activation of this progrowth protein is observed as nuclear translocation of β-catenin and formation of its complex with the T-cell factor (TCF) family of transcription factors.
