Název v původním jazyce

Expression of Ndi1p, an alternative NADH:ubiquinone oxidoreductase, increases mitochondrial membrane potential in a C. elegans model of mitochondrial disease

Popis výsledku v původním jazyce

The NADH:ubiquinone oxidoreductase or complex I of the mitochondrial respiratory chain is an intricate enzyme with a vital role in energy metabolism. We have previously developed a nematode model of complex I-associated mitochondrial dysfunction that features hallmark characteristics of mitochondrial disease, such as lactic acidosis and decreased respiration. We have expressed the Saccharomyces cerevisiae NDI1 gene in a strain of Caenorhabditis elegans with an impaired complex I. Expression of Ndi1p produces marked improvements in animal fitness and reproduction, increases respiration rates and restores mitochondrial membrane potential to wild type levels. Ndi1p functionally integrates into the nematode respiratory chain and mitigates the deleterious effects of a complex I deficit. However, we have also shown that Ndi1p cannot substitute for the absence of complex I. Nevertheless, the yeast Ndi1p should be considered as a candidate for gene therapy in human diseases involving complex I
