Asiatic Acid Ameliorates MNNG‐Induced Chronic Atrophic Gastritis by Inhibiting the Activation of the HRAS/PI3K/AKT/GSK3β Signaling Axis

Phytotherapy Research, EarlyView.
ABSTRACT Chronic atrophic gastritis (CAG), a widespread gastrointestinal condition, is widely acknowledged as a precursor to gastric cancer (GC). The incidence of CAG has been steadily increasing, yet effective pharmacological interventions remain unavailable. Asiatic acid (AA), a bioactive triterpenoid isolated from Centella asiatica, has demonstrated
