Caspase 9 Promoter Polymorphisms in Gastric Cancer, Mazandaran Province

Background and Gastric cancer is one of the most prevalent cancers with a low-five year survival rate. Some factors such as molecular pathway are associated with the development of disease and metastasis is the most important factor for death. Caspase 9 is initiator CASP of internal apoptosis pathway and have important role in cancer development. Polymorphism of CASP 9 gene promoter could influence the gene activity and cause sensitivity to cancer. In this case-control study, 100 patients with gastric cancer and 100 normal subjects were considered for caspase 9 promoter gene polymorphism. DNA extraction was performed from white blood cells according to manufacturer protocol. PCR-RFLP was carried out to detect -712 C>T gene polymorphism. Data was analyzed using SPSS V.18 and P<0.05 was considered significant. In the present study 200 subjects including 143 men and 57 women were studied. All subject were well matched for geographic area and race. The results showed a relationship between increase in allele T and gastric cancer (P= 0.095 r=0.0224). Screening of -712C>T caspase 9 polymorphism could be a marker in personal sensitivity to gastric cancer and useful in cancer treatment and prevention process.
