Effect of Jiawei Huangqi Guizhi decoction on the expression of gastrin content and phosphatidylinositol 3-kinase/ protein kinase B/mechanistic target of rapamycin complex 2 signalling pathways in rats with chronic atrophic gastritis.

OBJECTIVE

To investigate the effects of Jiawei Huangqi Guizhi decoction on chronic atrophic gastritis (CAG) in rats and its modulation of the phosphatidylinositol 3-kinase/protein kinase B/ mechanistic target of rapamycin complex 2 (PI3K/Akt/ mTORC2) signaling pathway.

METHODS

CAG was induced in rats and treated with high-, medium-, or low-dose Jiawei Huangqi Guizhi decoction. Gastric histopathology was observed by hematoxylin and eosin staining. Serum levels of gastrin, PI3K, Akt, and mTORC2 were detected by enzyme-linked immunosorbent assay. Gene and protein expression levels were analyzed by reverse transcription polymerase chain reaction and western blot.

RESULTS

The decoction alleviated gastric mucosal injury, reduced inflammation, and restored epithelial structure. It regulated PI3K, Akt, and mTORC2 expression at both mRNA and protein levels.

CONCLUSION

Jiawei Huangqi Guizhi decoction may prevent CAG progression by improving gastric tissue and modulating the PI3K/Akt/mTORC2 signaling pathway.
