Young Barley Indicates Antitumor Effects in Experimental Breast Cancer In Vivo and In Vitro

Area of Science:

• Phytochemistry
• Oncology
• Nutritional Science

Background:

• Dietary phytochemicals are investigated for cancer prevention.
• Young barley contains a mixture of bioactive compounds.
• Mammary carcinogenesis is a significant health concern.

Purpose of the Study:

• To evaluate the chemopreventive effect of young barley against N-methyl-N-nitrosourea-induced mammary carcinogenesis in female rats.
• To investigate the underlying mechanisms of action in vitro using MCF-7 breast cancer cells.

Main Methods:

• Female rats were administered N-methyl-N-nitrosourea and varying doses of young barley.
• Tumor tissues underwent histopathological and immunohistochemical analysis.
• In vitro studies utilized MCF-7 cells to assess cell survival, proliferation, and apoptosis.

Main Results:

• A mild antitumor effect was observed with 0.3% barley, but not with 3% barley.
• Barley increased caspase-3 expression and decreased Ki67 expression in rat tumor cells.
• In vitro, barley reduced MCF-7 cell survival, inhibited cell cycle progression, and induced apoptosis.

Conclusions:

• Young barley exhibits a chemopreventive effect against mammary carcinogenesis, likely due to its phytochemical mixture.
• Barley demonstrates potential as a dietary intervention for breast cancer prevention.
• Further research is warranted to elucidate the specific phytochemicals and mechanisms involved.
