When it comes to cancer, everyday there are millions of researches being done world-wide and treatment strategies being investigated for a hope of free-cancer in the future.
In a recent study done by the department of Science in Korean Medicine, Kyung Hee Universityand Departments of food Technology and biotechnology, Korea National University of Transportation, published on 3rd of May 2017 they suggested that Barley grass extract (Hordeum vulgare L.; Bex) has an anti-tumor activity particularly for both breast and prostate cancer. Unlike anti-cancer drugs that remain till today with their unwanted side-effects herbal medicine are always better in this area.
Barley grass was shown in the study to induce apoptosis in cancer cell-lines of breast and prostate cancer by increasing the reactive oxygen species (ROS) levels. They performed all experiments in triplicates; they treated the cancer cells with different concentrations of Barely grass at different time intervals. Barely was able to show a reduction in cancer-cell viability in a dose dependent manner.
The study also showed that, Barely induced caspase activation (which are needed for cell-death) and poly ADP ribose polymerase(PARP) cleavage (which are involved in several cellular processes such as DNA repair, genomic stability, and apoptosis) in the breast cancer cells. Thus, proving again that barely causes cancer-cell apoptosis.
For measuring barley’s ability to decrease the ROS, they treated the cancer cells with 100 μg/ml barley for 1 h, then detected it fluorometrically using flow cytometry, the data indicated that Barley ‑induced ROS accumulation is essential for apoptosis. Furthermore, Meta analyses indicated before that cereal can decrease cancer risk, so with this study it serves as a proof for the benefits of dietary components such as barley in cancer prevention and treatment.
Although chemical components to produce ROS and induce apoptotic cell death in those breast and prostate cancer cells still require further investigation, but this remains the first study, to show the role of Barely in cancer cell death.
