Phytochemical Indole-3-carbinol and Prostate cancer

 By Kyle J. Norton
Indole-3-carbinol is a phytochemical in the class of Indoles, by the breaking down of the glucosinolate glucobrassicin, found abundantly in cabbage, kale, Brussels sprouts, rutabaga, mustard greens, broccoli, etc.
Prostate cancer is defined as a condition in which the cells of prostate has become cancerous, causing abnormal cell growth which spread to the distant parts of the body. Most prostate cancers are slow growing and enlarged prostate and prostate cancer may be detected during the Physical (rectum) exams.
Indole-3-carbinol, has showed a strong evidence in supporting the use of  phytochemicals as epigenetic modulators for prostate cancer chemoprevention(1). Indole-3-carbinol (I3C), a common phytochemical in cruciferous vegetables, inhibited prostate cancer through induced G1 cell-cycle arrest and apoptosis in prostate cancer cells(2). In human PC-3 prostate cancer cell lines, the phytochemical also induced G1 cell cycle arrest of that leading to apoptosis, and regulates the expression of apoptosis-related genes(3). According to the Division of Cancer Prevention, National Cancer Institute, broccoli-derived compounds indole-3-carbinol (I3C) and 3,3'-diindolylmethane (DIM), showed to inhibit prostate cancer through modulation of the effect of androgen on CCL2-mediated pathways(4).
