Subcellular localization regulates BRCA1 function, and BRCA1 is exported to the cytoplasm following DNA damage in a p53-dependent manner. Because more than 50% of solid tumors harbor p53 mutations, it is possible that genetically wild-type (wt) BRCA1 is functionally abnormal through compromised nuclear-cytoplasmic shuttling in sporadic breast cancer patients with dysfunctional p53. In this stud...

Loss of heterozygosity on chromosomal arm 16q has been shown to be a frequent event in sporadic breast cancer and is suggested to be involved in cancer development through inactivation of a tumor-suppressor gene. To specify the commonly deleted region in which the unknown tumorsuppressor gene is located, a deletion map of chromosome 16 was constructed for 78 breast cancers, using 27 polymorphic...

BACKGROUND The contribution of BRCA germline mutational status to breast cancer patients' prognosis is unclear. We aimed to systematically review and perform meta-analysis of the available evidence of effects of BRCA germline mutations on multiple survival outcomes of breast cancer patients as a whole and in specific subgroups of interest, including those with triple negative breast cancer, tho...

The prevalence of BRCA1 gene mutations in breast cancer differs between diverse ethnic groups. Relatively little information is known about patterns of BRCA1 mutations in early-onset breast cancer in women of Uighur or Han descent, the major ethnic populations of the Xinjiang region in China. The aim of this study was to identify BRCA1 mutations in Uighur and Han patients with early-onset (age ...

Several components of the Fanconi anaemia (FA) family of proteins allow the formation of the DNA repair complex foci formed by proteins such as BRCA1/2 and RAD51. Because the genes that participate in the DNA repair pathway have been described as low-penetrance breast cancer susceptibility genes, we postulated that variants in FA genes could also be associated with sporadic breast cancer risk. ...

Male breast cancer, which represents only 1% of all breast cancers, is occasionally associated with a family history of breast cancer. Sporadic male breast cancers presenting with another primary breast cancer are extremely rare. In this article, we report on a 70-year-old male patient with bilateral multifocal and synchronous breast cancer and without a family history of breast cancer.

results based on the recent researches, certain mmps play critical role in breast cancer initiation, invasion, and metastasis. they can be regarded as predictive biomarkers of primary diagnosis and prognosis of breast cancer and have predictive value for evaluation of disease, tumor recurrence, invading of tumor cells to other sites and therapeutic outcomes. conclusions in summary, the results ...
