Tumor suppressor p53: regulation and function.
The p53 protein is a transcription factor involved in maintaining genomic integrity by controlling cell cycle progression and cell survival. Mutations in p53 are the most frequently seen genetic alterations in human cancer. The function of p53 is critical to the way many cancer treatments kill cells because radiotherapy and chemotherapy act in part by triggering programmed cell death in respons...
متن کاملRegulation of the p53 tumor suppressor protein.
Mutations in the p53 tumor suppressor gene occur in about 50% of all human tumors, making it the most frequent target for genetic alterations in cancer (for recent reviews on p53 see Refs. 1–5). Such mutations probably facilitate carcinogenesis primarily through abrogating the tumor suppressor activities of the wild type p53 protein, although at least some forms of tumor-associated mutant p53 p...
متن کاملMicrobial Regulation of p53 Tumor Suppressor
p53 tumor suppressor has been identified as a protein interacting with the large T antigen produced by simian vacuolating virus 40 (SV40). Subsequent research on p53 inhibition by SV40 and other tumor viruses has not only helped to gain a better understanding of viral biology, but also shaped our knowledge of human tumorigenesis. Recent studies have found, however, that inhibition of p53 is not...
متن کاملTumor suppressor p53 inhibits autoimmune inflammation and macrophage function.
The tumor suppressor p53 regulates apoptosis, cell cycle, and oncogenesis. To explore the roles of p53 in autoimmunity, we studied type 1 diabetes and innate immune responses using C57BL/6 mice deficient in p53. We found that p53-deficient mice were more susceptible to streptozotocin-induced diabetes than control mice, and they produced higher levels of interleukin-1, -6, and -12. The innate im...
متن کاملRole of tumor suppressor p53 in megakaryopoiesis and platelet function.
The pathobiological role of p53 has been widely studied, however, its role in normophysiology is relatively unexplored. We previously showed that p53 knock-down increased ploidy in megakaryocytic cultures. This study aims to examine the effect of p53 loss on in vivo megakaryopoiesis, platelet production, and function, and to investigate the basis for greater ploidy in p53(-/-) megakaryocytic cu...
