Summary: In this paper, the authors investigate the physiological role of an antioxidant enzyme, Hemeoxygenase-1(HO-1), and its relevance in the cardiovascular complications of systemic sclerosis (SSc). Authors use HoloMonitor to study endothelial cells' morphological and functional features in the presence of an HO-1 activator and selective inhibitors. The results demonstrate that inhibition of HO-1 significantly reduces cell proliferation and cell motility (migration) of cultured endothelial cells. In summary, results indicate a clear link between 1) downregulation of HO-1/CO signaling; and 2) pathophysiological processes occurring in the early phases of SSc, such as calcium homeostasis dysregulation, impaired angiogenesis and cardiac arrhythmias.
