Depleted folate pool and dysfunctional mitochondria associated with defective mitochondrial folate proteins sensitize Chinese ovary cell mutants to tert-butylhydroperoxide-induced oxidative stress and apoptosis.

Abstract excerpt

The functional role of mitochondrial (mt) folate-associated proteins in mammalian cells is not clearly understood. We investigated the respiratory function and apoptosis phenotype of Chinese hamster ovary (CHO) mutant cells with defective mt serine hydroxymethyltransferase (SHMT) activities (glyA...
