ADIPOR1 x PDHK1 x PP2A

The purpose of this research study is to determine if consuming arctigenin, a natural compound from a Chinese herb called Arctium lappa (commonly called greater burdock), is safe, and to measure the intake level of arctigenin in blood. Arctigenin is being studied by researchers for potential health benefits such as helping to lower the risk of inflammation and cancer. A human study has been done measuring the uptake of arctigenin into blood after consumption of the herb extract containing arctigenin, and found no toxicity. Studies in mice demonstrated that consumption of arctigenin in pure form at a safe level is highly effective in inhibition of prostate cancer growth. Therefore, this study is designed to evaluate the safety and uptake rate of pure arctigenin in humans, which may be potentially used in the future for prostate cancer prevention.
