Palliative Role of Aqueous Ginger Extract on N-Nitroso- N-Methylurea-Induced Gastric Cancer

Ginger (Zingiber officinale) is a spice and also an herbal medicine used worldwide for managing GI tract disturbances. However, its role in gastric Cancer is sparingly known. This study ensures the standardization of gastric Cancer by the induction of N-nitroso N-methyl Urea (MNU) and to determine the role of the aqueous extract of ginger (AGE) in MNU-induced gastric Cancer in albino Wistar rats. Accordingly, the Anticancer potential of AGE and its possible mode of action were assessed on rats exposed to MNU, by various biochemical and molecular assays. As evidenced by the extent of lipid peroxidation, Gastrin levels and histopathological sections in MNU-induced cancerous lesions at 8 wk which was stabilized at 16 wk confirming the induction of gastric carcinoma by the chemical carcinogen. Further, results revealed that AGE alleviated the oxidative stress as evidenced by the stomach antioxidant enzymes (SOD, catalase, GPx, and GR), markers of oxidative stress (TRx, GRx) and Gastrin, a specific marker for gastric Cancer and a decreased level of pro-inflammatory markers (NF-kB, TNF-α, IL-6, PGE₂) which was further confirmed by histopathological analysis. AGE is responsible to mitigate oxidative stress and inflammation related to gastric Cancer and could be used as a potential dietary intervention in gastric Cancer therapy.
