CLPTM1L polymorphism and lung cancer risk.

ABSTRACT: The association of Cleft Lip and Palate Transmembrane Protein 1 (CLPTM1L) rs31489 polymorphism with risk of lung cancer has been evaluated in many studies; however, the results from these studies are controversial. Thus, further analysis on association between CLPTM1L rs31489 polymorphism and risk of lung cancer is needed among a larger study population. A literature search in PubMed, Embase, Web of Science, Science Direct, SpringerLink, EBSCO, Wanfang, and Chinese National Knowledge Infrastructure (CNKI) databases was carried out to identify studies investigating the association between lung cancer risk and CLPTM1L rs31489 polymorphism. The strength of the association between CLPTM1L rs31489 polymorphism and lung cancer risk was estimated by calculating odds ratios (ORs) and corresponding 95% confidence intervals (CIs). In the overall analysis, there was significant association between CLPTM1L rs31489 polymorphism and lung cancer risk under an allele model (OR = 1.12; 95% CI, 1.06-1.18; P < 0.00001; I(2) = 57%). Subgroup analysis by ethnicity was performed. Stratified analysis by ethnicity showed that a statistically increased cancer risk was found in the Caucasian population (OR = 1.15; 95% CI, 1.10-1.21; P < 0.00001; I(2) = 22%), but there was no significant association between lung cancer risk and CLPTM1L rs31489 polymorphism in the Asian population (OR = 1.03; 95% CI, 0.97-1.08; P = 0.37; I(2) = 15%). In conclusion, this meta-analysis demonstrates that CLPTM1L rs31489 polymorphism significantly modified the risk of lung cancer.

Project description:The objective of the present study was to analyze the relationship between genetic polymorphisms of the rs2736098 locus of the telomerase reverse transcriptase (TERT) gene and the rs401681 locus of the cleft lip and palate transmembrane protein 1 (CLPTM1L) gene and the risk of developing lung cancer in males in Jinzhou. A total of 214 lung cancer patients who were admitted in Jinzhou Medical University were analyzed, and 216 healthy males were selected as controls. Venous blood from all subjects and data on relevant risk factors were collected. DNA was extracted from peripheral blood by the phenol-chloroform method. Real-time fluorescent quantitative PCR (TaqMan real-time PCR) was used for DNA amplification. The genotyping results of the genetic polymorphisms of the TERT rs2736098 and CLPTM1L rs401681 loci were detected. The risk of developing lung cancer in the population with the TERT rs2736098 locus carrying the T allele was 1.614 times that with the TERT rs2736098 locus carrying the C allele after adjustment of the age factor. The risk of developing lung cancer in the population carrying the TT mutant genotype and the CT genotype increased significantly compared with that carrying the CC wild genotype [odds ratio (OR)=1.815, 95% CI=1.132-2.957; OR=2.417, 95% CI=1.158-4.943]. Based on a comparison between the combination of the two mutant genotypes (CT+TT) and the wild homozygous genotype (CC), the mutant genotype increased the risk of developing lung cancer (OR=1.955, 95% CI=1.213-3.157). The risk of developing lung cancer in the population with the CLPTM1L rs401681 locus carrying the T allele was 1.399 times that carrying the C allele (OR=1.343, 95% CI=1.035-1.978). The population with the TERT rs2736098 locus carrying the mutant genotype (CT+TT) was associated with the number of tumors (OR=0.553, 95% CI=0.236-0.928). In conclusion, in males, the TERT rs2736098 and CLPTM1L rs401681 T alleles are the susceptibility factors for developing lung cancer. Individuals, including the smoking population, who carry both the TERT rs2736098 and CLPTM1L rs401681 T alleles are more likely to develop lung cancer.
