Abstract

骨质疏松症是一种典型的多基因复杂疾病,遗传力高达85%,其发病率已跃居常见疾病的第5位。尽管已经鉴定出大量骨质疏松易感SNP,但大多数SNP位点位于基因组非编码区,且功能机制未知。本研究旨在通过生物信息学分析和功能实验探究骨质疏松非编码功能性易感SNP rs4325274的分子调控机制。首先,通过表观注释发现该SNP所在区域处在增强子上,eQTL和Hi-C分析结果发现SNP调控的潜在靶基因是SOX6;然后,利用多种数据库进行Motif预测,并结合GEO数据库中的ChIP-seq数据分析进行了验证,结果发现转录因子HNF1A更倾向于结合SNP rs4325274-G碱基;进一步通过双荧光素酶报告基因实验验证了该SNP对SOX6基因表达的增强作用;最后,利用shRNA敲低转录因子HNF1A实验,检测靶基因SOX6的表达变化。以上研究结果初步解析了非编码区功能性SNPrs4325274作为增强子远程调控SOX6基因表达的分子机制,为复杂疾病非编码易感SNP的遗传调控研究提供新思路。.
