单基因突变,破坏线粒体呼吸链功能的C。线虫改变蛋白质表达和代谢物的模式。我们的目标是开发有用的分子指纹,采用适应性强的技术来识别电子传递链中的线粒体缺陷。我们分析了影响复合物I、复合物II或泛醌合成的突变,并发现了C. elegans对线粒体功能障碍的影响。这些模式是在KEGG途径保守的C。elegans到哺乳动物,验证线虫可以作为哺乳动物疾病的模型。此外,突变体之间存在特定差异,可能有助于诊断患者的特定线粒体疾病。
Single-gene mutations that disrupt mitochondrial respiratory chain function in C. elegans change patterns of protein expression and metabolites. Our goal was to develop useful molecular fingerprints employing adaptable techniques to recognize mitochondrial defects in the electron transport chain. We analyzed mutations affecting complex I, complex II, or ubiquinone synthesis and discovered overarching patterns in the response of C. elegans to mitochondrial dysfunction across all of the mutations studied. These patterns are in KEGG pathways conserved from C. elegans to mammals, verifying that the nematode can serve as a model for mammalian disease. In addition, specific differences exist between mutants that may be useful in diagnosing specific mitochondrial diseases in patients.
