Tumor 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 کاملTumor 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 کاملTumor suppressor p53 inhibits systemic autoimmune diseases by inducing regulatory T cells.
The tumor suppressor p53 plays a central role in tumor suppression by inducing apoptosis, cell cycle arrest, senescence, and DNA repair. In addition to the antitumor functions of p53, accumulating evidence using systemic p53-deficient mice suggests that p53 suppresses autoimmunity. However, it remains unknown how p53 suppresses autoimmunity. In this study, we generated T cell-specific p53-defic...
متن کاملCP-31398 restores mutant p53 tumor suppressor function and inhibits UVB-induced skin carcinogenesis in mice.
Mutations in the tumor suppressor p53 are detectable in over 50% of all human malignancies. Mutant p53 protein is incapable of transactivating its downstream target genes that are required for DNA repair and apoptosis. Chronic exposure to UVB induces p53 mutations and is carcinogenic in both murine and human skin. CP-31398, a styrylquinazoline compound, restores the tumor suppressor functions o...
متن کاملA Proinflammatory Cytokine Inhibits P53 Tumor Suppressor Activity
p53 has a key role in the negative regulation of cell proliferation, in the maintenance of genomic stability, and in the suppression of transformation and tumorigenesis. To identify novel regulators of p53, we undertook two functional screens to isolate genes which bypassed either p53-mediated growth arrest or apoptosis. In both screens, we isolated cDNAs encoding macrophage migration inhibitor...
