A278C mutation of dihydropteridine reductase decreases autophagy via mTOR signaling.

Abstract excerpt

Dihydropteridine reductase (QDPR) plays an important role in the recycling of BH4 and is closely related to oxidative stress. We have previously reported that the overexpression of QDPR in human kidney HEK293T cells significantly protected against oxidative stress, and these beneficial effects were abolished by A278C mutation. To evaluate the effect of wild-type and mutant QDPR on autophagy and its mechanism in...
