Chemoprotective Effect of Scutellarin against Gastric Cancer in Rats: An in vitro and in vivo Study

Abstract

This study evaluated the chemoprotective effect of scutellarin (SC) in vitro and in vivo against gastric carcinogenesis in rats and celllines and examined the underlying mechanism. Gastric cancer celllines (AGS) was used for the in vitro study and lactate dehydrogenase (LDH) profile, histone deacetylase (HDAC) assay, cell cycle & apoptosis ratio and antioxidant parameters were measured. N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) was used to induce gastric carcinogenesis in rats and the rats received the different doses of SC (10, 20 and 30 mg/kg). The body weight and tumor incidence were measured at regular time intervals. The antioxidant and pro-inflammatory cytokines were estimated. The finding of data showed that the drug was effective against AGS cell line. Supplementation of scutellarin revealed an upregulation in body weight compared with the MNNG group rats. Moreover, it also reduced the incidence of tumor. It also altered the significant DNA density, LDH content, mucus content and acidity. Scutellarin treated rats showed improved activity in enzymatic and non-enzymatic antioxidant profile and reversed the content of cytokines compared with MNNG induced gastric cancer group rats. This research reveals the chemoprotective property of the scutellarin and highlights the promising role of drug by alteration of inflammatory pathway by minimizing its adverse effect.
