Thus far, the most successful strategies for targeting p53 have relied on reverting the mutant form of p53 back to its wild-type form or on the inhibition of the interaction between wild-type p53 and MDM2 or MDM4, a structural homologue of MDM2.1 Both of these approaches have led to the testing of potential novel therapeutic agents in clinical trials. In turn, p53 activates genes that stop cell growth or even trigger the cell to die. They managed to bring cancer cells back under control by reactivating the cells' cancer suppressor genes using an extract from axolotl oocytes. Epub 2022 Apr 22.

Other functions allow users to search the lists of keywords and use other options to refine their results. This interpretation was consistent with the. __By stopping cells with mutated or damaged DNA from dividing, p53 helps prevent the development of tumors. In metastasis, cancer cells break, away from where they first formed, travel through the blood or lymph system, and, form new tumors in other parts of the body. Oncogenes normally function to accelerate cell division and growth. The tumor suppressor p53 gene is the most frequently mutated gene in high-grade serous ovarian cancer, the deadliest subtype responsible for 70% of ovarian cancer deaths.
