WebMar 1, 2000 · The ARF tumor suppressor connects pathways regulated by the retinoblastoma protein and p53. ARF inactivation reduces p53-dependent apoptosis … WebLoss of p53 function by genetic mutation or alterations in its pathway, such as p19Arf loss and/or mdm2 over-expression, inhibits cell death and is critical for tumor progression. Interferon-β (IFN), an immune-stimulatory cytokine, is also frequently lost in some tumor types, fact that could inhibit an anti-tumor immune response.

Of note is that while Ras induces ARF expression, it also increases the levels and activity of MDM2, both through elevated MDM2 transcription and …
WebThe role of this p14ARF-hdm2-p53 regulatory pathway in breast carcinoma is unknown. We hypothesized that p14 ARF mutations and HDM2 gene amplification may be alternative mechanisms of p53 inactivation in breast cancer. Mutational analysis of TP53 (exons 5–9) ... WebP14ARF is a central actor of the cell cycle regulation process as it participates to the ARF-MDM2-p53 pathway and the Rb-E2F-1 pathway. It is the physiological inhibitor of MDM2, an E3 ubiquitin ligase controlling the activity and stability of P53, and loss of P14ARF activity may have a similar effect as loss of P53.
WebThe ARF–p53 pathway. A cardinal feature of ARF-null MEFs is their capacity to grow as established cell lines and to be transformed by oncogenicras genes alone (Kamijo et al. 1997). Approximately 20% of spontaneously established fibroblast cell lines derived from MEFs of wild-type mice undergo biallelic ARF loss.
