Purpose:
Renal cell carcinoma (RCC) accounts for about 3% of all cancer-related mortalities worldwide and the risk factors for the development of RCC have not yet been fully elucidated. Mounting proteomic evidence suggests that inflammatory process plays a role in RCC etiology, and interleukin-10 (IL-10) is an important immunosuppressive cytokine. However, little is known about the contribution of IL-10 genotypes to RCC. The study aimed at evaluating the contribution of IL-10 promoter A-1082G (rs1800896), T-819C (rs3021097), A-592C (rs1800872) genetic polymorphisms to the risk of RCC in Taiwan.
Materials and Methods:
Associations of the three IL-10 polymorphic genotypes with the risk of RCC were examined among 92 RCC patients and 580 age- and gender-matched cancer-free controls by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) methodology.
Results:
The pilot results showed that the percentages of TT and TC for IL-10 T-819C genotypes were significantly higher in the RCC patient group than those in the healthy control group. The CC genotype carriers were of lower risk for RCC (odds ratio=0.45, 95% confidence interval=0.23-0.72, p=0.0033). There is no difference in the distribution of A-1082G or A-592C genotype between the RCC and control groups.
Conclusions:
In summary, the CC genotype of IL-10 T-819C genotype may have a protective effect on RCC risk in Taiwan. Further investigation with larger sample size in addition to genotype-phenotype correlation and intracellular mechanisms are our future work.
