Article name: Dietary Potassium Downregulates Angiotensin-I Converting Enzyme, Renin, and Angiotensin Converting Enzyme 2
This article was published in the Journal of Clinical Investigation in 2023. It is a study that compares the renin in renal tissue by immunohistochemistry of rat kidneys of rats that had a supplemented amount of potassium in the diet versus controls.
The kidneys in the rats with a diet with supplemented potassium had less number of juxtaglomerular cells positive for renin in the wall of afferent arterioles, and a significant reduction in renin mRNA abundance, compared to non potassium supplemented.
