Abstract: ) while reducing pathogenic taxa. LC-MS analysis further demonstrated restoration of bile acid homeostasis, characterized by elevated primary bile acids (GCA, CDCA) and decreased secondary bile acids (DCA, LCA). Mechanistically, the intervention significantly inhibited PI3K/AKT signaling, as confirmed by Western blot and immunohistochemistry. Bioinformatic analysis further identified PI3K/AKT as a central regulatory pathway. These findings indicate that probiotic-assisted CUR therapy reverses GEM resistance by remodeling the gut microbiota and its metabolic outputs, thereby suppressing oncogenic signaling pathways. This strategy provides a promising microbiota-based approach for improving therapeutic outcomes in GBC.
