TP53 and atherosclerosis: We did an extensive search using the PubMed database with the medical subject headings (MeSH) keywords “sirtuin'' and “atherosclerosis.” The reviewed literature reported that sirtuins prevent and ameliorate atherosclerosis by halting inflammation, apoptosis, oxidative stress, and regulating low-density lipoprotein (LDL) cholesterol. Sirtuin 1 (SIRT1) and sirtuin 6 (SIRT6) inhibit the RELA component of NF-kB, thus suppressing inflammation, SIRT1 inhibits p53 by deacetylation, and the latter stabilize telomeres thus preventing apoptosis and cell death.
