| Outline of Final Research Achievements |
Ghrelin is an important hormone that regulates appetite and eating behavior, and modulates energy metabolism. We performed SNPs analysis of the ghrelin gene (GHRL) and the ghrelin receptor gene (GHSR) and examined its relationship with the childhood obesity in Japan. We recruited and analysed 165 healthy school-aged subjects and 46 obese children from 2010 to 2014. We selected the five SNPs of GHRL: g.-604A>G (rs27647), g.-501C>A (rs26802), g.247C>A(rs696217), g.265A>T (rs4684677), g.62G>T (rs35683), and the three SNPs of GHSR: g.171C>T(rs495225), g.447C>G (rs2232169), g.477G>A (rs572169). The SNPs were genotyped using Taqman SNP Genotyping Assays. The genotype AA of g.-501C>A was associated with the occurrence of pediatric obesity (OR 14.05: 95%Cl 5.76-34.28, p <0.001). We also didn’t identify the relationship between childhood obesity and the 3 SNPs of GHSR. Our study suggested that the GHRL g.-501C>A polymorphism was strongly associated with pediatric obesity in Japan.
