HIF1A and hypertensive disorder: Using Western blotting protein expression of HIF-1α was found to be increased under high salt diet (Li et al., 2008; Wang et al., 2010) and in DOCA/salt hypertension (Dallatu et al., 2014) and to be decreased in hypertension induced by nitric oxide synthase inhibition in combination with high salt diet (Dallatu et al., 2013).
