Ciona intestinalis NADH dehydrogenase NDX confers stress-resistance and extended lifespan on Drosophila.


PMID 25124484

Abstract

An assembled cDNA coding for the putative single-subunit NADH dehydrogenase (NDX) of Ciona intestinalis was introduced into Drosophila melanogaster. The encoded protein was found to localize to mitochondria and to confer rotenone-insensitive substrate oxidation in organello. Transgenic flies exhibited increased resistance to menadione, starvation and temperature stress, and manifested a sex and diet-dependent increase in mean lifespan of 20-50%. However, NDX was able only weakly to complement the phenotypes produced by the knockdown of complex I subunits.
