There is strong evidence suggesting that endoplasmic reticulum stress contributes to neurogenic and vascular hypertension in various animal models, however this has never been explored in humans. Therefore, this project will fill this gap by performing a single-blind, placebo-controlled trial in humans with hypertension.
The endoplasmic reticulum is a multipurpose organelle found in most human cells, including those in the brain and the endothelium of blood vessels. One of the primary functions of the endoplasmic reticulum is the posttranslational folding of new proteins and the reprocessing of misfolded or damaged proteins. Physiological and pathophysiological conditions can lead to the accumulation of unfolded/misfolded proteins, thus triggering the unfolded protein response which is a quality control system that maintains endoplasmic reticulum homeostasis. However, with prolonged or severe exposure to endop…

Endoplasmic reticulum stress will be inhibited by chronic (8 weeks) oral ingestion of the dietary supplement tauroursodeoxycholic acid (TUDCA; 1,750 mg/day)
Placebo pills containing microcrystalline cellulose will be ingested over the course of the 8 week intervention.
