Disease relevance of E4F1

 

High impact information on E4F1

 

Biological context of E4F1

  • E4F1, a possible inducer of cell growth arrest, was markedly increased only in ER alpha-positive VSMCs by estrogens in both microarray and RT-PCR analyses [5].
  • Collectively, our data reveal that E4F1 is a key posttranslational regulator of p53, which modulates its effector functions involved in alternative cell fates: growth arrest or apoptosis [2].
  • These and other results suggest that the E4 promoter may be comprised solely of multiple E4F1 binding sites and a TATA box [1].
  • A cellular transcription factor E4F1 interacts with an E1a-inducible enhancer and mediates constitutive enhancer function in vitro [1].
  • Mouse embryos lacking E4F die at an early developmental stage, whereas enforced expression of E4F1 in various cell lines inhibits cell cycle progression [6].

Regulatory relationships of E4F1

 

Other interactions of E4F1

  • E4F1 is therefore considered one of the estrogen-responsive genes involving ER alpha-mediated inhibition of VSMC proliferation and may play an important role in estrogen-related atheroprotection of human aorta [5].
