(redirected from E2F-1)

E2F1

A gene on chromosome 20q11.2 that encodes a member of the E2F family of DNA-binding transcription factors, which play a key role in regulating the cell cycle and tumour suppressor proteins. E2Fs are targets of transforming proteins of small DNA tumour viruses.

TQ inhibited DNA synthesis, proliferation, and viability of cancerous prostate epithelial cells by down-regulating androgen receptors and E2F-1, a regulator of cell proliferation and viability, without affecting the noncancerous cells (34), inhibited benzo(a)pyrene (BP)induced forestomach carcinogenesis (35), prevented MCA-induced fibrosarcoma tumours (36), and blocked tumour angiogenesis in a xenograft human prostate cancer in mice (37).
In addition, CDC25A can accumulate as a result of transcription activation of E2F-1 and c-myc and elevated levels of RNA and protein stimulate cells to enter the cell cycle.
