Abstract: FOXO transcription factors are important regulators of cell survival in response to a variety of stress stimuli, among which are oxidative stress, DNA damage, and nutrient deprivation. Here we report a role for FOXO3a under conditions of hypoxic stress. In response to hypoxia, FOXO3a transcript levels accumulate in an HIF1-dependent way, resulting in enhanced FOXO3a activity. We show that transcription of CITED2, a transcriptional cofactor that functions in a negative feedback loop to control HIF1 activity, is… Show more
