Podocyte YAP ablation decreases podocyte adhesion and exacerbates FSGS progression through α3β1 integrin.

Severe proteinuria in focal segmental glomerulosclerosis (FSGS) is closely associated with decreased adhesion, and subsequent loss, of podocytes. Yes-associated protein (YAP) is a key transcriptional coactivator that plays a significant role in maintaining cellular homeostasis. However, its role in podocyte adhesion and its specific mechanism in FSGS progression remain unclear.
