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

iLABMED, 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 ...

Different demographic drivers of recovery in two adjacent populations of a long‐lived bird of prey

Oikos, EarlyView.
Understanding the demographic mechanisms underlying population decline or recovery is critical for conservation and management, yet similar population trends may arise from very different underlying processes. Comparing populations of vulnerable species groups like long‐lived raptors in different environments can reveal how species respond to change ...
