Disease relevance of E2f3

 

High impact information on E2f3

 

Biological context of E2f3

  • Mutation of E2f3 dramatically impairs the mitogen-induced, transcriptional activation of numerous E2F-responsive genes [7].
  • Here we show that E2F3 also has a significant effect on the phenotype of tumor-prone Rb(+/-) mice [1].
  • We also identified patterns of gene expression that specifically differentiate the activity of E2F1 and E2F3; this profile is enriched in genes known to function in mitosis [8].
  • Gene expression profiles that distinguish either E2F1- or E2F3-expressing cells from quiescent cells are enriched in genes encoding cell cycle and DNA replication activities, consistent with many past studies [8].
  • In contrast to the E2F3a product that is tightly regulated by cell growth, the E2F3b product is expressed equivalently in quiescent and proliferating cells [9].
 

Anatomical context of E2f3

 

Associations of E2f3 with chemical compounds

  • As opposed to UVB-exposed skin, UVB-induced tumors showed elevated levels of E2F1, but these were reduced in silibinin-treated tumors without any effect on E2F2 and E2F3 [14].
 

Physical interactions of E2f3

 

Regulatory relationships of E2f3

  • E2F3 loss suppresses the development of the pituitary tumors that normally account for the death of Rb(+/-) mice [1].
  • We now show that additional E2F target genes share a common promoter architecture and are also regulated by the combined action of TFE3 and E2F3 [16].
  • In contrast, the thymidine kinase (TK-1) promoter is also regulated by E2F3 but independent of TFE3 [16].
 

Other interactions of E2f3

  • E2F3 contributes both to the inappropriate proliferation and to the apoptosis arising in Rb mutant embryos [6].
  • Consistent with this notion, Arf mutation suppresses the activation of p53 and p21(Cip1) in E2f3-deficient MEFs [5].
