Disease relevance of TCF4

  • Hemizygosity of TCF4 is one of the causes of Pitt-Hopkins   syndrome [1]. Multiple individuals are identified who have hemizygous deletions of all or a part of this gene. Penetrance is very high since no hemizygous individuals have been identified without this phenotype.
  • Hedgehog (Hh) signaling restricts the expression of Wnt targets to the base of the colonic crypt in vivo, and transfection of Ihh into colon cancer cells leads to a downregulation of both components of the nuclear TCF4-beta-catenin complex and abrogates endogenous Wnt signaling in vitro [2].
  • A colorectal carcinoma cell line, DLD-1, was engineered to suppress transactivation by the TCF4/beta-catenin complex in a dominant-negative manner under the strict control of the tetracycline regulatory system [3].
  • The full-length TCF4 cDNA clone was obtained from a HTLV-1 transformed human peripheral T cell MACHERMAKER cDNA library with NRE as the bait in yeast one-hybrid system [4].
  • Chromatin immunoprecipitation experiments in LNCaP prostate cancer cells showed that endogenous AR was bound to a Tcf4-responsive element in the c-myc promoter [5].
  • HASH-1 and E2-2 are expressed in human neuroblastoma cells and form a functional complex [6].
 

Psychiatry related information on TCF4

  • Analysis of genome-wide CAG/CTG repeats, and at SEF2-1B and ERDA1 in schizophrenia and bipolar affective disorder [7].
  • ITF2 was found to directly bind to negative acting Id HLH proteins and positive acting bHLH proteins such as scleraxis [8].
  • At present no strong evidence exists that large repeat alleles at either SEF2-1B or ERDA1 are involved in the etiology of schizophrenia or bipolar disorder [9].
 

High impact information on TCF4

 

Chemical compound and disease context of TCF4

  • Src-dependent activation of beta-catenin was prevented by SKI-606, a novel Src family kinase inhibitor, which also abrogated beta-catenin nuclear function by impairing its binding to the TCF4 transcription factor and its trans-activating ability in colorectal cancer cells [13].

Associations of TCF4 with chemical compounds

  • Furthermore, TCF4, which is one of the transcriptional factors in the Wnt signaling pathway and has a mononucleotide repeat sequence (a nine- adenine repeat, (A)9) in its C-terminal region, was mutated in 13 of the 33 samples [21].
  • Furthermore, the ectopic expression of beta-catenin-TCF4 in cells that constitutively express low levels of the transactivation complex produces a significant increase of GLCE transcript level and, at the same time, enhances the rate of D-glucuronic acid epimerization in HS [22].
  • In cells transfected with dominant negative CREB lithium-stimulated proliferation was unchanged whereas blocking Wnt/beta-catenin by dominant negative TCF4 reduced proliferation by approx. 50% [23].
  • These include inhibition of, both the biochemical activation of ILK, inhibition of serine 9 GSK3beta phosphorylation and the enhancement of TCF-4 transcriptional activity [24].
  • Ca(2+) strongly induced E-cadherin expression and inhibited the expression of the nuclear transcription factor, TCF4 [25].
 

Physical interactions of TCF4

  • The HASH-1/E2-2 complex binds an E-box (CACCTG) in vitro, and transactivates an E-box containing reporter construct in vivo [6].
  • Binding studies in solution and in heterogeneous phase showed that TCF4 binds reversibly to beta-catenin with an affinity (KB) of 3(+/-1) 10(8) M(-1) [26].
