5-Fluorouracil (5-FU) is a cornerstone of chemotherapy for colorectal cancer (CRC), and the major targets of 5-FU are thymidylate synthase (TS), methylenetetrahydrofolate reductase (MTHFR), and reduced folate carrier 1 (RFC1). We hypothesized that polymorphisms in the genes encoding these proteins would be associated with CRC patient survival.We genotyped the following polymorphisms in 372 CRC patients:...
Numerous studies have focused on the association between miR-34 family members, which are direct p53 targets, and carcinogenesis of many cancers, including hepatocellular carcinoma (HCC). This study aimed to assess whether polymorphisms in the single-nucleotide polymorphism miR-34b/c T>C (rs4938723) and TP53 Arg72Pro (rs1042522) increase the risk of HCC and influence outcome in patients with HCC...
Polymorphisms of endothelial nitric oxide synthases (eNOS) have been shown to be associated with cancer susceptibility. However, the results of such studies are conflicting to date. We investigated whether polymorphisms of the eNOS gene correlated with patients with colorectal cancer (CRC), relative to healthy individuals.In the present study, we analyzed three polymorphisms of eNOS (-786T>C, 4a4b,...
Recent studies have suggested that common genetic polymorphisms alter the processing of microRNA (miRNA) and may be associated with the development and progression of cancer.The association of miRNA polymorphisms with HCC survival was analyzed in 159 HCC patients and 201 controls by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method.The risk of HCC was significantly...
The aim of this study was to investigate the association of microRNA polymorphisms (miR-146aC>G, miR-149T>C, miR-196a2T>C, and miR-499A>G) in Korean patients with recurrent spontaneous abortion (RSA).We conducted a case–control study of 564 Korean women: 330 patients with at least two unexplained consecutive pregnancy losses and 234 healthy controls with at least one live birth and no...
