Abstract
Gastric cancer is the most typical oncological illness globally. Though the incidence of gastric cancer has dropped dramatically over the last few years, the survival rate is yet concerning due to poor diagnostic strategy. The etiology of gastric cancer is majorly associated with dietary factors. For this reason, application of nontoxic natural agents with anticancer effects for patients is needed. Diosmin has been commonly utilized to treat various diseases both traditionally and now clinically. However, its effect on gastric carcinogenesis remains unclear. The effects of diosmin were used to evaluate how N-methyl-N-nitrosourea (MNU) induces gastric carcinogenesis in rats. The general and gross assessment of MNU in experimental animals was tabulated. Biological tumor markers (gastrin, ALP, LDH, and γ-GT) were examined. Oxidative markers (LPO) and antioxidative markers (GSH, vitamin E, and vitamin C) were determined. In addition, inflammatory cytokines (thioredoxin, glutaredoxin, NF-κB, TNF-α, IL-6, PGE2) were explored and justified with histopathological studies. Overall, the results showed positive anticancer activity demonstrated by improved body weight, reduced tumor rate, decreased oxidative marker value by increased antioxidative rate, and suppressed tumor biomarkers and inflammatory cytokines. The histopathological analysis was congruent with the data observed. Our conclusion that diosmin exerts its anticancer activity by up-regulation of antioxidants which might be responsible for amelioration of oxidative stress and inflammatory cytokines in carcinogenesis to prevent gastric cancer.
