Smooth muscle cell calcineurin is required for angiotensin-II-induced abdominal aortic aneurysm formation. Representative images of hematoxylin–eosin (top row), Masson trichrome (middle row), and Van Gieson (bottom row) staining on abdominal aorta sections from calcineurin control mice (left), mice conditionally lacking calcineurin in endothelial cells (middle), and mice conditionally lacking calcineurin in smooth muscle cells (right), with and without angiotensin-II treatment.
Calcineurin is a phosphatase implicated in AngII-induced abdominal aortic #aneurysm (AAA). This study reveals a novel, phosphatase-independent mechanism by which #Calcineurin contributes to AAA, dependent on transcriptional reprogramming of #SmoothMuscleCells @plosbiology.org 🧪 plos.io/4kfnT3L
