摘要: The two products of the Ink4a-Arf locus, p16(Ink4a) and p19(Arf) (p14(ARF) in humans), are potent tumor suppressors that regulate activities retinoblastoma protein p53 transcription factor. These proteins form part a signaling network is disrupted most, if not all, cancer cells. locus responds to stress signals, limiting cell proliferation modulating oncogene-induced apoptosis. Recent evidence emerging from mouse models distinguishes regulating onset identifies differences their responsiveness drugs.
