Anti-ADIPOQ monoclonal antibody, clone C983N

Background: Coronary Heart Disease (CHD) is one of the leading causes of death in the world with a projected global 82 million DALYs by 2020. Genetic and environmental factors contribute to CHD development. Here, the authors investigate the association between CHD risk and three Single Nucleotide Polymorphisms (SNPs) in the AdipoQ gene (rs3774261, rs1063537 and rs2082940); and the interaction of this association with environmental factors, in Northeast Han Chinese population. Methods: Using a case-control study design, 1514 participants (754 cases and 760 controls) were investigated. Three variants in the AdipoQ gene (rs3774261, rs1063537 and rs2082940) were selected and genotyped. The online SNPstats program and SPSS 21.0 software were used for data analyses. Results: The authors found that the rs3774261G allele is associated with the risk of CHD but that the rs2082940T allele protects against CHD. No significant association was found between rs1063537 and CHD risk. The study also found significant interactions between triglyceride levels and the SNPs studied (P < 0.0001 for rs3774261, P = 0.014 for rs1063537, and P = 0.031 for rs2082940). Conclusions: Variations in AdipoQ gene can protect against CHD (as with rs2082940T) or associated with CHD risk (as with rs3774261G) in Northeast Han Chinese - findings that will help shed light on the reported conflicting roles of AdipoQ in cardiovascular diseases. Serum triglycerides levels also interact in the AdipoQ - CHD association, thus further highlighting the roles environmental factors play in the genetic aspect of diseases.

Aim: To investigate the association between adiponectin (ADIPOQ) genotypes and colorectal cancer (CRC) risk among Taiwanese. Materials and Methods: Polymerase chain reaction-restriction fragment length polymorphism was adopted to identify ADIPOQ rs266729, rs2241766 and rs1501299 genotypes among 362 CRC patients and 362 healthy controls. Results: ADIPOQ rs266729 GG genotype (p= 0.0075) and G allele (p= 0.0061) are associated with a significantly increased CRC risk. There is no differential distribution of rs2241766 and rs1501299 genotypes. As for the gene-lifestyle interaction, there are obvious joint effects of rs266729 genotype on the CRC risk among non-smoker, non-alcohol drinker, while not on smoker or non-drinker subgroups. No significant correlation was observed between rs266729 genotypic distributions and age, gender, tumor size, location or metastasis status. Interestingly, a correlation of rs266729 genotype and larger BMI on CRC risk was found. Conclusion: G allele at ADIPOQ rs266729 may serve as a determiner for CRC risk, especially for those with BMI >= 24.
