This study investigated the level of plasma hypoxia-inducible factor (HIF)-1α and cytochrome c (CytoC) in correlation with C-reactive protein, dyslipidaemia, insulin resistance, and prognostic factors in Type 2 diabetic patients in Saudi Arabia. Reduced level of HIF-1α and non-significant increased level of CytoC correlated negatively with these prognostic factors. These results pointed to a possible pathogenetic implication for HIF-1α.
