Publication The Requirement of p53 in Oral MSC differentiation Which Leads to Kaposi’s Sarcoma(2016-08-01) Alsenani, MayP53 is considered one of the most important defense proteins against cancer.Although the p53 mutation is associated with many cancers, its mutation is never found in Kaposi’s sarcoma (KS), raising a possibility that functional p53 may play a role in KS development. To assess the role of p53 in Kaposi’s sarcoma tumor, shRNA-mediated gene silencing was used to knockdown p53 expression. We examined Kaposi’s sarcoma-associated herpesvirus (KSHV)-infected periodontal ligaments stem cells (PDLSC) for osteogenic differentiation and endothelial angiogenesis, and we observed noticeable decreases in osteogenic differentiation and angiogenesis when p53 expression was knocked down in KSHV-infected PDLSCs by p53 specific shRNA. The results suggest that p53 plays an essential role in sarcoma development of KSHV infected mesenchymal stem cells.
