Abstract:

(ZO) and(TC) are plants used for the treatment of diverse illnesses in traditional medicine. The present study investigates the preventive effect of-extract (ZOTC) against DMBA-induced breast cancer in a rat model. Bioactive compounds from ZO (6-gingerol, 6-shogaol) and TC (gallic acid, ellagic acid, corilagin, chebulinic acid, and chebulagic acid) were detected using high-performance liquid chromatography. Mammary carcinogenesis was induced in rats with a single subcutaneous injection of 7,12-Dimethylbenz[a]anthracene (DMBA). Oral administration of ZOTC ameliorated the antioxidant status in mammary tissues, serum lipid levels, and serum cytokines. Histological analysis of the mammary tissue (normal and tumor) was carried out to obtain pathological alterations due to ZOTC treatment. The effect of ZOTC on the mechanistic target of rapamycin (mTOR) gene and accumulation of corresponding gene product was also investigated. mTOR plays a central role in cell metabolism and proliferation in normal and cancer cells. Transcriptional and immunohistochemical analysis showed the downregulation of mTOR expression in the mammary tissues of ZOTC-treated rats. In conclusion, the results obtained suggest that ZOTC can suppress tumor progression in DMBA-induced breast cancer ratsinhibition of the mTOR pathway.
