Polymorphisms in the vascular endothelial growth factor gene and breast cancer in the Cancer Prevention Study II cohort.
Abstract
Vascular endothelial growth factor (VEGF) plays a central role in promoting angiogenesis and is over-expressed in breast cancer. At least four polymorphisms in the VEGF gene have been associated with changes in VEGF expression levels: -2578C/A, -1154G/A and -634G/C are all located in the promoter region; and +936C/T is located in the 3'-untranslated region. We examined the association between these four VEGF polymorphisms and risk for breast cancer among postmenopausal women in CPS-II (Cancer Prevention Study II) Nutrition Cohort. This cohort was established in 1992 and participants were invited to provide a blood sample between 1998 and 2001. Included in this analysis were 501 postmenopausal women who provided a blood sample and were diagnosed with breast cancer between 1992 and 2001 (cases). Control individuals were 504 cancer-free postmenopausal women matched to the cases with respect to age, race/ethnicity, and date of blood collection (controls). We found no association between any of the polymorphisms examined and overall breast cancer risk. However, associations were markedly different in separate analyses of invasive cancer (n = 380) and in situ cancer (n = 107). The -2578C and -1154G alleles, which are both hypothesize...Continue Reading

Angiogenesis Inhibitors to Treat Cancer
Cancer treatments including angiogenesis inhibitors prevent tumor cells from receiving nutrients and oxygen. Here is the latest research on angiogenesis inhibitors for the treatment of cancer.
Cancer Incidence & Mortality
Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.

Breast Cancer: Chemo-Resistance
Some cancers are difficult to treat and aggressive including the "triple-negative" breast cancer. This type of cancer is chemoresistant even before chemotherapy begins. Here are the latest discoveries chemo-resistance in breast cancer.
