A gene that has been coined "the guardian of the genome," when inactivated, it can also play a role in the persistence, growth, and spread of a cancer that develops. Give the position and acceleration as a function of time. One of the challenges with monotherapy will be durability, Dr. Parikh noted. One approach includes p53 treatments that prevent the degradation of the wild-type p53, which is important for maintaining the tumor-suppressive status, said Aparna R. Parikh, MD, of Harvard Medical School. Several observational studies have shown that patients who were treated with statins had a decreased incidence of cancer.11,12 Recently, Dr. Baranda's colleague from The University of Kansas, Tomoo Iwakuma, MD, PhD, demonstrated in an in vitro assay that atorvastatin was able to selectively suppress the levels of mutant p53 and tumor cell growth in conformational, mutated p53, while wild-type and DNA contact mutants were not as sensitive to atorvastatin-induced degradation of the p53 protein. is necessary for the disease to spread. 2022 May;41(22):3051-3063. doi: 10.1038/s41388-022-02296-9.
