A Novel Protein NAB1‐356 Encoded by circRNA circNAB1 Mitigates Atrial Fibrillation by Reducing Inflammation and Fibrosis

open access: yesAdvanced Science, EarlyView.
The circRNA circNAB1 is downregulated in AF patient. Silencing circNAB1 promotes collagen deposition and inflammation, whereas overexpression reduces AF susceptibility. circNAB1 encodes the protein NAB1 356 that interacts with EGR1 to mitigate fibrosis and inflammation.

GLS1‐Mediated Redundancy in Glutamate Accelerates Arterial Calcification via Activating NMDAR/Ca2+/β‐Catenin Pathway

open access: yesAdvanced Science, EarlyView.
GLS1 is a novel contributor to arterial calcification. GLS1‐catalyzed glutamate exerts the promoting effects on osteogenic reprogramming in arteries. NMDAR, a glutamate receptor, is also activated and overexpressed during arterial calcification.

Exercise without Weight Loss Prevents Seasonal Decline in Vitamin D Metabolites: The VitaDEx Randomized Controlled Trial

open access: yesAdvanced Science, EarlyView.
In people with overweight or obesity, regular exercise even without weight loss or vitamin D supplementation completely prevents the usual winter decline in the vitamin D metabolite that maintains health at a cellular level, 1,25(OH)2D3, and ameliorates the decline in the vitamin D status marker 25(OH)D.
