(Submitter supplied) TP53 mutations occur in approximately 50% of all human tumors with increased frequency in aggressive cancers that are notoriously difficult to treat. Additionally, p53 missense mutations are remarkably predictive of refractoriness to chemo/radiotherapy in various malignancies. These observations have led to the development of mutant-p53 targeting agents that restore p53 function. An important unknown is which p53-mutant tumors will respond to p53 reactivation-based therapies. more...

(Submitter supplied) Microarray expression data generated to determine the impact of defined p53 mutations on lung cancer cell phenotypes, and on the tumour supressive responses induced by WT p53 restoration. In murine models of lung cancer, the therapeutic benefit of WT p53 restoration has been demonstrated in p53-deficient tumours (Juntilla et al, 2010; Feldser et al, 2010). However, it remains unknown if the restoration of WT p53 function is beneficial in p53 mutant tumours. more...

(Submitter supplied) The tumor suppressor gene p53 is frequently mutated in human breast cancer and is a marker for poor prognosis and resistance to chemotherapy. Transplantation of p53-null mouse mammary epithelium into syngeneic wild-type mice leads to normal mammary gland development followed by spontaneous mammary tumors that recapitulate many of the phenotypic, molecular, and genetic features of human breast cancer. more...

(Submitter supplied) Apc(D716) mutant mice develop benign intestinal adenoma, while Apc(D716) and p53 R270H compound mutant mice develop invasive adenocarcinoma in the intestine. We examined expression profile of tumor-derived organoids using Apc(D716), Apc(D716) p53 Null, Apc(D716) p53 R270H mutant mice by RNA sequencing, and identified mutant p53-induced gene set.

(Submitter supplied) Salivary tumors isolated from MMTV-ras transgenic mice expressing wild-type p53, no p53 or p53R172H gain-of-funcion mutant were subjected to genome-wide gene expression profiling to assess the effect of the different p53 status on tumor gene expression.

(Submitter supplied) We used gene transcript profiling to gain a deeper understanding of the role of FBXW7 in tumor development and to determine the influence of mTOR inhibition by rapamycin on tumor transcriptome and biological functions. In comparison to tumors from p53 single heterozygous (p53+/-) mice, we find that tumors from Fbxw7/p53 double heterozygous (Fbxw7+/-p53+/-) mice show significant deregulation of cholesterol metabolic processes independent of rapamycin treatment, while cell cycle related genes were upregulated in tumors from placebo treated Fbxw7+/-p53+/- mice, but not in tumors from rapamycin treated Fbxw7+/-p53+/- mice. more...
