Association analysis of genetic variants of adiponectin gene and risk of pancreatic cancer.

ABSTRACT: Adiponectin is a cytokine exclusively secreted from adipocyte, and could perform direct or indirect effects on anti-inflammation and anti-tumor. Previous researches have studied the correlation between plasma adiponectin levels and the risk of pancreatic cancer. So we aimed at investigating the association of genetic variants of adiponectin gene and the risk of pancreatic cancer. In this study, we genotyped 6 SNPs of adiponectin gene in a case-control study of recruited 172 patients of pancreatic cancer and 181 healthy people in Chinese Han population. The results indicated that two of the SNPs had significant associations with pancreatic cancer. Of which, the SNP rs1501299C>A decreased the risk of PC (P=0.016, OR=0.662 95% CI 0.472-0.928), while rs1065358T>C increased the risk of PC (P=0.027, OR=1.421 95% CI 1.040-1.941). Furthermore, in the clinical correlation analysis, we found rs1501299 was correlated with tumor size (P=0.026), cigarette smoking (P=0.022) and alcohol consumption (P=0.001) and rs1063538 was correlated with alcohol consumption (P=0.026). In conclusion, we provided evidences that the variants in adiponectin gene might influence the development and progression of pancreatic cancer.

Project description:BACKGROUND: Metabolic syndrome traits play an important role in the development of colorectal cancer. Adipokines, key metabolic syndrome cellular mediators, when abnormal, may induce carcinogenesis. METHODOLOGY/PRINCIPAL FINDINGS: To investigate whether polymorphisms of important adipokines, adiponectin (ADIPOQ) and its receptors, either alone or in combination with environmental factors, are implicated in colorectal cancer, a two-stage case-control study was conducted. In the first stage, we evaluated 24 tag single nucleotide polymorphisms (tag SNPs) across ADIPOQ ligand and two ADIPOQ receptors (ADIPOR1 and ADIPOR2) among 470 cases and 458 controls. One SNP with promising association was then analyzed in stage 2 among 314 cases and 355 controls. In our study, ADIPOQ rs1063538 was consistently associated with increased colorectal cancer risk, with an odds ratio (OR) of 1.94 (95%CI: 1.48-2.54) for CC genotype compared with TT genotype. In two-factor gene-environment interaction analyses, rs1063538 presented significant interactions with smoking status, family history of cancer and alcohol use, with ORs of 4.52 (95%CI: 2.78-7.34), 3.18 (95%CI: 1.73-5.82) and 1.97 (95%CI: 1.27-3.04) for smokers, individuals with family history of cancer or drinkers with CC genotype compared with non-smokers, individuals without family history of cancer or non-drinkers with TT genotype, respectively. Multifactor gene-environment interactions analysis revealed significant interactions between ADIPOQ rs1063538, ADIPOR1 rs1539355, smoking status and BMI. Individuals carrying one, two and at least three risk factors presented 1.18-fold (95%CI:0.89-fold to 1.58-fold), 1.87-fold (95%CI: 1.38-fold to 2.54-fold) and 4.39-fold (95%CI: 2.75-fold to 7.01-fold) increased colorectal cancer risk compared with those who without risk factor, respectively (P(trend) <0.0001). CONCLUSIONS/SIGNIFICANCE: Our results suggest that variants in ADIPOQ may contribute to increased colorectal cancer risk in Chinese and this contribution may be modified by environmental factors, such as smoking status, family history of cancer and BMI.
