Abstract:
Objective To investigate the relationship between single nucleotide polymorphism of SET8 gene and the risk of clear cell renal cell carcinoma (CCRCC). Methods We selected 140 CCRCC patients and 130 healthy controls in this case?control study. Genotype of single nucleotide polymorphism ( rs16917496) at the miR?502 binding site in the 3′UTR of SET8 mRNA in the CCRCC patients and healthy controls was tested and the association between genotype and risk of cancer was assessed. The expression of SET8 was determined by immunohistochemistry and the relationship between expression of SET8 and genotype of rs16917496 was analyzed. Results In the control group, CC, CT and TT genotypes were found in 30, 32 and 68 persons, respectively, while in the CCRCC patients, CC, CT and TT genotypes were found in 14 , 47 and 79 cases, respectively. The frequencies of rs16917496 CT and TT genotypes in the CCRCC group were significantly higher than those in the control group ( P<0.05) . Compared with the CC genotype, patients with CT and TT genotypes were more susceptible to develop CCRCC ( P<0. 05 ) . CT and TT genotypes of rs16917496 at the miR?502 binding site of the SET8 gene were associated with expression of SET8. Conclusions Genotype of the SNP rs16917496 at the miR?502 binding site in the 3′ untranslated region of the SET8 gene is associated with the expression of SET8 protein. Analysis of genetic polymorphisms in miRNA binding sites may help to identify the subgroups of population susceptible to CCRCC.
