Abstract

Background: Verbascoside (VB) inhibits endoplasmic reticulum stress (ERS), but its therapeutic potential in hypertension (HTN) is unclear.

Aim: To investigate whether VB inhibits ERS by modulating the Nur77/GFPT2/CHOP axis, thereby ameliorating angiotensin II (Ang II)-induced HTN.

Methods: The cell biological behaviour of HUVECs was determined by CCK-8, LDH kit, scratch assay, and adhesion assay. Oxidative stress factor levels were detected by flow cytometry and kits. The levels of ERS and the Nur77/GFPT2/CHOP pathway-related proteins were examined through Western blot.

Results: VB increased the viability of Ang II-treated HUVECs, inhibited LDH release, and reduced cell migration and adhesion. VB also reduced ERS marker protein levels, while inhibiting oxidative stress and modulating the Nur77/GFPT2/CHOP pathway. VB lowered blood pressure and increased elastic fibre deposition in HTN mice, and Nur77 agonists enhanced the protective impact of VB.

Conclusion: VB hindered Ang II-induced endothelial dysfunction and ERS through modulating the Nur77/GFPT2/CHOP pathway.
