Gender-dependent association of type 2 diabetes with the vasoactive intestinal peptide receptor 1
چکیده انگلیسی

Type 2 diabetes is characterized by an inadequate pancreatic beta-cell response to the progressive insulin resistance. Its pathogenesis is complex and has been connected with a state of preclinical chronic inflammation. Vasoactive intestinal peptide (VIP) and its receptors play a relevant role in the homeostasis of insulin secretion as well as in the control of inflammation. In particular, VIP receptor 1 (VPAC1) has been found to be down-modulated during inflammation, and to be associated with several diseases. The objective of this study was to compare the distribution of SNPs mapping in the VIP receptor 1 gene in cases with type 2 diabetes and matched controls. Seven hundred cases with type 2 diabetes (423 males and 277 females) and 830 random controls (419 males and 411 females) were analyzed for the distribution of three common SNPs mapping in the VPAC1 gene. The results show a significantly different genotype distribution of the SNP rs9677 in the 3’-UTR of VPAC1 in female cases with type 2 diabetes compared to gender-matched controls (ptrend = 6 × 10− 4). The rs9677 CC genotype confers the highest risk (OR: 2.1) and correlates with worse clinical parameters such as higher level of total cholesterol, higher LDL/HDL ratio and a higher HbA1c concentration. The genetic association reported here indicates that VIP/VPAC1 signaling can be a relevant pathway in the pathogenesis of type 2 diabetes in females suggesting that at least some aspects of the genetic predisposition to this disease can be gender-specific.


► Three SNPs mapping in the VPAC1 gene are analyzed in T2D patients vs controls.
► Haplotype frequencies of two 3′-UTR SNPs are different in females with T2D.
► Rs9677 CC risk genotype correlates with worse clinical parameters in T2D females.
