- Abstract
The 2-oxoglutarate and iron dependent dioxygenase family are crucial for cellular adaptation to changes in oxygen concentration. We found that cells with OGFOD1 gene silencing in this family showed resistance to cell death under ischemia, and cDNA microarray analysis of OGFOD1 knockout human cells revealed downregulation of ATPAF1. Although reintroduction of the OGFOD1 wild-type gene to OGFOD1 KO cells restored ATPAF1 mRNA levels, the catalytically inactive OGFOD1 mutants did not. Furthermore, introduction of ATPAF1 gene to OGFOD1 KO cells induced ischemic cell death. Thus, OGFOD1 plays an important role in ischemic cell survival and an OGFOD1 iron binding residue is required for ATPAF1 gene expression.
