Abstract

• HIF-1α is activated following myocardial infarction, and is a critical transcription factor promoting survival in hypoxia.

• Type 2 diabetes blunts HIF-1α activation in ischemia and downstream adaptation to hypoxia.

• This effect is mediated by increased long-chain fatty acids, which prevent HIF-1α activation in hypoxia.

• Succinate promotes HIF-1α activation by inhibiting the regulatory HIF hydroxylases. Fatty acids decrease succinate concentrations in hypoxia, by blocking increased glycolysis and malate-aspartate shuttle activity.

• Pharmacologically activating HIF-1α or increasing succinate concentrations restores the hypoxic response and improves functional recovery post-ischemia in diabetes.
