Abstract
IL-12 is an antitumor cytokine with functions of inhibiting tumor growth, invasion, and metastasis, indicating that IL-12 is a promising candidate for cancer treatment. The aim of this study was to investigate the association of IL-12A rs568408, IL-12A rs2243115, and IL-12B rs3212227 with the susceptibility to colorectal cancer (CRC). Two hundred and fifty-seven histopathologically confirmed CRC patients and 236 age- and gender-matched controls were enrolled. The three polymorphisms were genotyped using a polymerase chain reaction-restriction fragment length polymorphism assay. We found that the IL-12A rs568408 AG/AA genotypes were associated with an increased risk of CRC with an adjusted odds ratio (OR) of 1.66 (95 % confidence interval (CI), 1.11-2.48). Stratified analyses showed that patients carrying the IL-12B rs3212227AC/CC genotypes had a 1.97-fold increased risk of tumor metastasis (OR = 1.97; 95 % CI, 1.04-3.70). Gene-gene interaction analysis showed that subjects carrying the IL-12A rs568408AG/AA and IL-12B rs3212227AA genotypes had a 2.40-fold increased risk of CRC (OR = 2.40; 95 % CI, 1.14-5.07) and individuals carrying the IL-12A rs568408AG/AA and IL-12B rs3212227AC/CC genotypes had a 1.93-fold increased risk of CRC (OR = 1.93; 95 % CI, 1.10-3.41). These findings indicate that IL-12A rs568408 and IL-12B rs3212227 may be related to the development of CRC.Entities:
