GPX4 and Aortic dissection: lncRNA NORAD is downregulated in the aorta of patients with aortic dissection, and overexpression of NORAD promotes the growth of vascular smooth muscle cells (VSMCs) and inhibits ferroptosis induced by AngII.519 The mechanism may be related to the interaction between NORAD and HUR, which promotes the stability of GPX4 mRNA and increase GPX4 levels.
