WebLoss of function mutations in tumor suppressor genes has been identified in many types of cancers, including ovarian, lung, colorectal, head and neck, pancreatic, uterine, breast, and bladder cancer 1). Examples of tumor suppressor genes include BRCA1, BRCA2, and p53 or TP53. A tumor suppressor gene is like the brake pedal on a car. Webp53 was the first human tumor suppressor gene identified by mutational analysis of sporadic tumors, and since then several others have been described. Classic tumor suppressor genes are defined by mutation in both familial and sporadic forms of cancer.

WebThe adenovirus E1A oncogene activates p53 through a signaling pathway involving the retinoblastoma protein and the tumor suppressor p19 ARF. 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. WebInterestingly, inhibition of the oncogene MDM2 also led to an upregulation of wild-type p53 expression and phosphorylation. In conclusion, we find that miR-3928, through the downregulation of several oncogenes and upregulation and activation of wild-type p53, is a strong tumor suppressor in GBM.
