p53 mutations in breast cancer.
We have identified and analyzed 41 mutations in p53 in sporadic breast tumors from 136 unselected breast cancer patients and estimate that approximately 40% of such tumors contain p53 mutations. The frequency of G-T transversions and the incidence of guanosine mutations in the nontranscribed strand of the p53 gene were found to be higher than expected, and we suggest, therefore, that exogenous ...
متن کاملMutations in p53, p53 protein overexpression and breast cancer survival
p53 is an important tumour suppressor gene that encodes p53 protein, a molecule involved in cell cycle regulation and has been inconsistently linked to breast cancer survival. Using archived tumour tissue from a population-based sample of 859 women diagnosed with breast cancer between 1996 and 1997, we determined p53 mutations in exons 5-8 and p53 protein overexpression. We examined the associa...
متن کاملSomatic p53 mutations in human breast carcinomas in an Icelandic population: a prognostic factor.
Mutations in the p53 gene are among the most common genetic changes in human carcinomas. They have been found in many tumor types including colon, lung, and breast. We have used constant denaturant gel electrophoresis in order to screen samples from 109 breast carcinomas for mutations in four conserved regions, exons 5, 7, and 8, of the p53 gene. Samples were also analyzed for allelic loss of t...
متن کاملCXCL12/CXCR4 Gene Polymorphism as a Putative Prognostic Factor for Metastasizing Breast Cancer under Chemotherapy
The receptor and the receptor axis CXCL12 / CXCR4 are the two pairs studied in the metastasis of breast cancer. The purpose of this study was to investigate the relationship between the occurrence of CXCR4 / CXCL12 genes polymorphism and the clinical and pathological characteristics of patients with metastatic breast cancer under chemotherapy. Material and methods: Genomic DNA was extracted f...
متن کاملPrognostic value of P53 gene mutations in a large series of node-negative breast cancer patients.
The most important subgroup of breast cancer patients for which reliable prognostic factors are needed are women without axillary lymph node involvement. Although overall, these patients have a good prognosis, it is known that 20-30% will experience a recurrence of the disease. To determine the prognostic significance of P53 tumor suppressor gene mutation, specimens from 113 primary breast canc...
