BACKGROUND SIRT1 expression and Notch1 signaling have been implicated in tumorigenesis in many cancers, but their association with survival in breast cancer has not been determined. The purpose of this study was to assess the possible prognostic value of SIRT1, N1IC, and Snail expression in breast cancer patients. METHODS Immunohistochemistry was(More)
The purpose of this study is to summarize the currently available evidence regarding the concerned issue by performing a comprehensive meta-analysis. Relevant publications reporting the association of metformin use with survival of lung cancer patients with diabetes were electronically searched to identify eligible studies. The meta-analysis was performed(More)
PURPOSE Catechol-O-methyltransferase (COMT) enzyme plays a central role in estrogen-induced carcinogenesis. Emerging evidence from association studies has revealed that the functional Val158Met polymorphism (rs4680 G>A) of the Catechol-O-methyltransferase gene (COMT) has been implicated in susceptibility to breast cancer in the Chinese population, while(More)
BACKGROUND Previous studies have investigated the associations between the common polymorphisms in FAS/FASL genes and lung cancer risk; however, the results remain inconsistent and inconclusive. Hence, we performed a meta-analysis to reassess the relationships between FAS rs2234767 and FASL rs763110 polymorphisms and the risk of lung cancer. METHODS(More)
