Abstract:
Objective To detect the association between rs4646999 polymorphisms in the promoter region of the c-Jun and the prognosis of sporadic colorectal cancer. Methods rs4646999-673C>T genetypes were deter-mined by Taqman-MGB probes in 436 colorectal cancer cases. The survival curve was analyzed by Kaplan-Meier analysis and Cox regression.Western blot was used to analyze the expression levels of c-Jun protein in different gen-otypes. Results Univariate analysis showed that the cumulative survival rate of patients with rs4646999TT geno-type was significantly higher than that of patients with CT and CC genotype. Multivariate Cox regression analysis showed that the differentiation,lymph node metastasis,distant metastasis,TNM stage and rs4646999 genetypes were prognostic factors.Compared with the carriers of TT genotype,CT/CC complex genotypes were associated with poor prognosis of colorectal cancer(P<0.05).Protein expression analysis showed that the expression of c-Jun pro-tein in CC genotype was increased.In contrast,the TT genotype was decreased.Conclusions This study provided the evidence that rs4646999-673C>T genetic variant in c-Jun promoter regions is associated with the poor survival prognosis of colorectal cancer,possibly by elevating the protein expression levels that appeared to up-regulate activ-ity of c-Jun thus tumorigenesis.
