    Abstract:
    Naturally occurring phytochemicals especially polyphenolic compounds have received increasing attention as chemopreventive agents. The chemopreventive potential of the ethanolic extract of Salvadora persica L. fruits SP, (the arak tree or miswak) on 7,12-dimethylbenz (a) anthracene (DMBA)-induced mammary carcinogenesis in female albino rats was investigated in this work. Ethanolic extract of SP fruits was supplemented to the experimental groups at a concentration of 500 mg/kg body weight for 22 weeks. Administration of SP extract suppressed DMBA-induced mammary carcinogenesis as revealed by incidence of tumors in histological investigation. There was a significant reduction in cell proliferation and an increase in apoptosis with downregulation of estrogen receptor expression in the mammary tissue of SP-treated animals. Additionally, SP extract prevented the oxidative damage induced in breast tissues of DMBA-treated rats. SP treatment also decreased the viability of MCF-7 breast cancer cells and induced early and late apoptosis and induced S cell cycle arrest. The chemo-preventive properties and anticancer effects of SP could be attributed to its anti-oxidative and a high percentage of phenolic compounds and esters which were detected here in the SP fruit extract.
