Therapeutic ANGPTL2 suppression could antagonize development of heart failure

The research group led by Professor Yuichi Oike at Kumamoto University reported that expression of angiopoietin-like protein 2 (ANGPTL2) increases in pathologically-remodeled hearts of mice and humans, while decreased cardiac ANGPTL2 expression occurs in physiological cardiac remodelling induced by endurance training in mice. Mice overexpressing ANGPTL2 in heart show cardiac dysfunction caused by both inactivation of AKT and sarco(endo)plasmic reticulum Ca2+-ATPase (SERCA)2a signalling and decreased myocardial energy metabolism. Conversely, Angptl2 knockout mice exhibit increased left ventricular contractility and upregulated AKT-SERCA2a signalling and energy metabolism. Finally, ANGPTL2-knockdown in mice subjected to pressure overload ameliorates cardiac dysfunction. Overall, these studies suggest that therapeutic ANGPTL2 suppression could antagonize development of heart failure.

A trans-regional research led by Prof. Yu HUANG of CUHK has revealed that YAP/TAZ, a transcriptional regulator in vascular endothelial cells, has close links to vascular inflammation and the formation of atherosclerosis. Based on the studies made on induced atherosclerotic mice, the research team has elucidated new therapeutic targets against atherosclerosis.
