Aim To explore the possible association between insulin like growth factor Ⅱ receptor( IGF2R)rs9456497 polymorphism and cardiovascular risks in a long-lived population residing Guangxi Hongshui River basin.Methods IGF2 R rs9456497 polymorphism was genotyped by i MLDR technique for 496 Zhuang long-lived individuals( long-living group) and their offspring( offspring group,n= 723) and matched healthy controls( control group,n = 611)living in Hongshui River basin. Association analysis were then conducted among ...
胰岛素样生长因子2受体(insulin like growthfactorⅡreceptor,IGF2R)基因全长约136 kb,位于6q26,含48个外显子[1],主要负责转运新合成的酸性水解酶至溶酶体,参与负性转化生长因子TGF-β1的激活及其配体IGF2的解离和内化[2]。IGF2R基因突变影响IGF2R与IGF2的结合能力,在成人期?
