本研究通过系统地鉴定受 T2D 相关基因位点调控的基因中的核编码线粒体基因 (NEMG)，研究了 2 型糖尿病 (T2D) 脂肪组织线粒体功能障碍的潜在遗传机制。这些“疾病位点”的目标基因是通过使用高分辨率遗传图谱绘制与疾病和基因表达水平相关的遗传位点（表达数量性状位点，eQTL）来识别的，并且独立估计值共同定位在较小的遗传距离内。这些共定位信号被定义为 T2D-eQTL，目标基因被定义为 T2D 顺式基因。总共有 763 个顺式基因与 T2D-eQTL 相关，其中 50 个是 NEMG。 T2D 和胰岛素抵抗病例和对照的独立基因表达数据集证实，顺式基因和顺式 NEMG 在病例中的差异表达得到富集，为遗传图谱可以识别信息丰富的功能基因提供了独立验证。另外两个结果与 T2D-eQTL 在 T2D 风险背景下调节 50 个已识别的顺式 NEMG 中的潜在作用一致：（1）与其他 NEMG 相比，50 个顺式 NEMG 表现出更大的差异表达；（2）如果其他 NEMG 的表达水平与 50 个顺式 NEMG 的子集相关性更高，则它们表现出表达显着降低的趋势。这 50 个顺式 NEMG 具有差异表达并与绘制的 T2D 疾病位点相关，编码在关键线粒体途径中起作用的蛋白质，包括一些当前的治疗兴趣，例如支链氨基酸、GABA 和生物素的代谢。
This study investigated the potential genetic mechanisms which underlie adipose tissue mitochondrial dysfunction in Type 2 diabetes (T2D), by systematically identifying nuclear-encoded mitochondrial genes (NEMGs) among the genes regulated by T2D-associated genetic loci. The target genes of these ‘disease loci’ were identified by mapping genetic loci associated with both disease and gene expression levels (expression quantitative trait loci, eQTL) using high resolution genetic maps, with independent estimates co-locating to within a small genetic distance. These co-locating signals were defined as T2D-eQTL and the target genes as T2D cis-genes. In total, 763 cis-genes were associated with T2D-eQTL, of which 50 were NEMGs. Independent gene expression datasets for T2D and insulin resistant cases and controls confirmed that the cis-genes and cis-NEMGs were enriched for differential expression in cases, providing independent validation that genetic maps can identify informative functional genes. Two additional results were consistent with a potential role of T2D-eQTL in regulating the 50 identified cis-NEMGs in the context of T2D risk: (1) the 50 cis-NEMGs showed greater differential expression compared to other NEMGs and (2) other NEMGs showed a trend towards significantly decreased expression if their expression levels correlated more highly with the subset of 50 cis-NEMGs. These 50 cis-NEMGs, which are differentially expressed and associated with mapped T2D disease loci, encode proteins acting within key mitochondrial pathways, including some of current therapeutic interest such as the metabolism of branched-chain amino acids, GABA and biotin.
