查询词典 gene

The hypermethylation of 5 CpG in promoter region serves as a mechanism of the inactivation of RASSF1A gene. This mechanism has been widely confirmed in multiple tumorgenesis including prostate carcinoma cell line DU145. Object Our study is to disclose the epigenic mechanism of the carcinogenesis of prostate cancer. Including: 1. We use demethylation agents in combination with chemotherapeutic drugs, to disclose whether demethylation agents can enhance the anticancer effect of chemotherapeutic drugs. 2. to study whether demethylation drugs can affect the methylation level of RASSF1A gene in.
