WebJul 19, 2024 · TP53 is one of the most extensively studied tumor suppressor genes whose multifaceted mechanisms involve apoptosis, ferroptosis, DNA repair, genomic stabilization, and angiogenesis [ 2 ]. Thus,... WebMar 3, 2009 · The tumor suppressor p53 negatively regulates a number of genes, including the proto-oncogene c-Myc, in addition to activating many other genes. One mechanism of the p53-mediated c-Myc repression may involve transcriptional regulation.

E1A signaling to p53 involves the p19ARF tumor suppressor
WebSimilarly the mutational inactivation of the APC tumor suppressor protein, which is required for the degradation of the oncogene β-catenin or the mutation of Rb, which then liberates the E2F-1 oncogene, each result in the enhanced synthesis of ARF by the E2F-1 or β-catenin transcription factors, and this results in p53 activation and ... WebThe adenovirus E1A oncogene activates p53 through a signaling pathway involving the retinoblastoma protein and the tumor suppressor p19ARF. The ability of E1A to induce p53 and its transcriptional targets is severely compromised in ARF-null cells, which remain resistant to apoptosis following serum depletion or adriamycin treatment.
