p53 plays a role in regulation or progression through the cell cycle, apoptosis, and genomic stability by means of several mechanisms: • It can activate DNA repair proteins when DNA has sustained damage. Thus, it may be an important factor in aging. • It can arrest growth by holding the cell cycle at the G1/S regulation point on DNA damage recognition—if it holds the cell her… WebApr 13, 2024 · This study investigated the effect of BaP on the expression of cytochrome P450 1A (CYP1A) and tumor suppressor protein p53 in brown bullhead (Ameiurus nebulosus).

WebApr 2, 2024 · It’s especially challenging to target mutant forms of p53 because they are generally inactive proteins, and most cancer drugs work by shutting off overactive proteins. Genes like TP53 that control cell growth and become inactive when mutated are called tumor suppressor genes. Webp53, also known as Tumor protein P53, cellular tumor antigen p53 (UniProt name), or transformation-related protein 53 (TRP53) is a regulatory protein that is often mutated in human cancers.
