Objective: To investigate the anti-gastric precancerous lesions effect and mechanism of Traditional Chinese Medicine Jinlongshe (JLS) granules in ethanol extractive of (EEA)-induced gastric precancerous lesions rats.
Methods: A rat model with the part typical proliferation of the gastric epithelium mucosa was established by EEA. These rats received different doses of JLS granules treatment for four weeks. Bodyweight, histological and ultrastructural changes of gastric precancerous lesions were evaluated. The expression of Apelin and CD34 mRNA and proteins of the gastric tissue were analyzed by quantitative Realtime PCR, western blot and immunohistochemical staining.
Results: We found that the treatment of JLS granules prevented the bodyweight loss and improved behavioral abnormalities of rats that received EEA. The histological and ultrastructural analysis also showed that JLS granules ameliorated EEA induced gastric precancerous lesions in a dose-dependent manner. The expression levels of two critical proteins involved in the angiogenesis of gastric carcinoma, Apelin, and CD34, were significantly reduced by the treatment of JLS granules.
Conclusion: Our results indicated that JLS could inhibit the expression of the Apelin and CD34 genes in rat gastric mucosa, which reversed gastric precancerous lesions.
