Core Tip
Core Tip: This study identified four exercise-responsive skeletal muscle-expressed genes (LAMA4, PECAM1, PXDN and THBS4), which were mechanistically linked to metabolic dysfunction-associated steatotic liver disease (MASLD). These genes may serve as myokine-like candidates, shedding light on the molecular pathways by which exercise mediates metabolic adaptation in MASLD. The findings provided novel insights into the pathophysiology of MASLD and suggested these biomarkers as promising candidates for precision diagnostics and therapeutic interventions.
