文题释义:
多态性:指在一生物群体中,同时和经常存在两种或多种不连续的变异型或基因型或等位基因,亦称遗传多态性或基因多态性。从本质上来讲,多态性的产生在于基因水平上的变异,一般发生在基因序列中不编码蛋白的区域和没有重要调节功能的区域。多态性90%以上为单核苷酸多态性,主要是指在基因组水平上由单个核苷酸的变异所引起的DNA序列多态性。它是人类可遗传的变异中最常见的一种。
胰岛素样生长因子1:属于胰岛素样生长因子家族成员,为一种分子结构类似于胰岛素的多功能细胞增殖调控因子,在细胞的分化、增殖、个体的生长发育中具有重要的促进作用。其生物学功能主要是通过特异性结合靶细胞表面的胰岛素样生长因子1受体而实现。

摘要
背景:
胰岛素样生长因子1在骨细胞功能及骨代谢的调节中发挥重要作用。目前为止,胰岛素样生长因子1受体基因多态性与绝经后骨质疏松的相关性尚未见报道。
目的:探讨胰岛素样生长因子1受体基因rs2229765单核苷酸多态性与绝经后妇女骨质疏松的相关性。
方法:应用PCR-RFLP技术测定甘肃地区218例绝经后骨质疏松患者及270例骨量正常绝经妇女的胰岛素样生长因子1受体基因rs2229765多态性位点基因型。采用双能X射线吸收骨密度仪检测受试者腰椎、股骨颈以及前臂骨密度。应用ELISA测定血清胰岛素样生长因子1。
结果与结论:①rs2229765多态性AA基因型(29% vs.17%,P=0.001)及等位基因A(51% vs.40%,P=0.000)在绝经后骨质疏松组中的分布频率显著高于骨量正常组;②与rs2229765基因型GG相比,基因型AA显著增加骨质疏松患病风险(OR=2.12,95%CI:1.27-3.54,P=0.004);③血清胰岛素样生长因子1分析结果显示,骨质疏松组中rs2229765 AA基因型(P=0.007)及GA 基因型(P=0.016)妇女血清胰岛素样生长因子1水平显著低于GG基因型;④结果表明,胰岛素样生长因子1受体基因rs2229765多态性与绝经后妇女骨质疏松具有相关性,并可能改变血清胰岛素样生长因子1水平。

Abstract:

BACKGROUND: Insulin-like growth factor 1(IGF-1) plays an important role in regulating osteocyte function and bone metabolism. The association of insulin-like growth factor 1 receptor (IGF-1R) gene polymorphisms with osteoporosis in postmenopausal women has not yet been reported.
OBJECTIVE: To investigate the correlation between IGF-1R gene rs2229765 single nucleotide polymorphism and osteoporosis in postmenopausal women.
METHODS: IGF-1R gene rs2229765 SNPs were detected using PCR-RFLP in 218 patients with postmenopausal osteoporosis and 270 postmenopausal women with normal bone mineral density. The bone mineral density of the lumbar spine, femoral neck and forearm was determined by dual-energy X-ray absorptiometry. Serum IGF-1 level was investigated by ELISA.
RESULTS AND CONCLUSION: The AA genotype (29% vs. 17%, P=0.001) and A allele (51% vs. 40%, P=0.000) distributions of the rs2229765 polymorphism in the osteoporosis group were significantly higher than those in the control group. Compared with GG genotype of rs2229765, AA genotype was significantly associated with an increased risk of osteoporosis (OR=2.12, 95%CI=1.27-3.54, P=0.004). The analysis of serum IGF-1 showed that osteoporotic women with rs2229765AA (P=0.007) and GA (P=0.016) genotype were found to have a lower serum IGF-1 level than osteoporotic women with GG genotype. Our results indicate that the IGF-1R gene rs2229765 polymorphism capable of regulating serum IGF-1 level is associated with postmenopausal osteoporosis.
