Regulatory Effects of Ammonium Chloride in an In Vitro Model of Hepatic Encephalopathy: Mechanisms Involving ACTA2‐Mediated Cytoskeletal Remodeling

open access: yesiLABMED, EarlyView.
Hyperammonemic stress suppresses ACTA2 expression and induces F‐actin cytoskeletal remodeling in astrocytes. The resulting inhibition of FAK/c‐Src signaling contributes to apoptosis, G2/M arrest, AQP4‐mediated swelling and junction‐associated proteins dysregulation, revealing a central role for ACTA2‐dependent cytoskeletal dysfunction in hepatic ...
