摘要:: Cyclin D1 is involved in normal regulation of the cell cycle and plays an important role in the transition from G1 to S phase of the cell cycle. The CCND1 gene has a G-->A polymorphism in exon 4 that increases the frequency of alternate splicing. We analyzed the potential role of CCND1 gene polymorphisms in lung cancer patients (n = 151) and in a matched control population (n = 151). DNA was isolated from blood samples, and exon 4 of CCND1 was amplified by polymerase chain reaction. After digestion with MspI, common CCND1 polymorphic alleles were analyzed by means of agarose gel electrophoresis. The data obtained were analyzed using multiple logistic regression. After adjustment for age, sex, and smoking status, the AG genotype was associated with an increased risk for overall lung cancer (odds ratio OR = 1.7, 95% confidence interval CI = 0.92-3.14). No association was found between AA genotype and risk of lung cancer. In smokers, the combined AG+AA genotypes of CCND1 were found to be significant (OR = 1.9, 95% CI = 1.03-3.71, P = 0.03). No positive association was found between CCND1 genotypes in nonsmokers. The results suggest that the CCND1 A870G gene polymorphisms may increase the risk of lung cancer in smokers from north India.
