Scientists may have found a bioactive compound isolated from the cruciferous vegetable for the prevention and treatment of prostate cancer with no side effects, according to studies.
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 a medical and chronic condition in which the cells of the prostate have become cancerous due to the alternation of the cell's DNA.
Most prostate cancers are slow-growing and enlarged prostate and prostate cancer may be detected during the Physical (rectum) exams.
Primary prostate cancer normally starts from the cell on the surface of the inner lining of the prostate tissue and gradually spreads to the deeper part of the prostate.
At the early stage, patients may not experience any symptoms, However, at the advanced stage, prostate cancer can induce symptoms of blood in the urine, frequent urination and urinary difficulty.
The cancer cells at this stage can also travel a distance away from the prostate to invade other healthy tissue and organ, leading secondary metastasis tumors.
According to the statistic, the 5-year survival rate for local and regional (stage 0 and 1) stages of prostate cancer is nearly 100%.
Therefore, men who are at higher risk of prostate cancer due to family history and increase in age and inherited gene changes should have their prostate gland checked annually.
Believe it or not, more than 80% of prostate cancers are diagnosed in men who are 65 or older.
Dr. Roberto Fabiani, the lead scientist at the University of Perugia suggested that people who follow the Western diet pattern are at increased risk of prostate cancer onset.
According to the results from the review of 12 observational studies included in the meta-analysis which identified a “Healthy pattern” and a “Western pattern”, he said, "The Healthy pattern was not related to PC risk (OR = 0.96; 95% confidence interval (CI): 0.88–1.04) while the Western pattern significantly increased it (OR = 1.34; 95% CI: 1.08–1.65)".
In other words, by a change of diet from high in saturated and trans fat, red meat and processed foods to diet high in fruits and vegetables and whole-grain, the risk of prostate cancer can be reversed.
In order to reaffirm the epidemiological evidence which suggested that intake of cruciferous vegetable intake is associated with a reduced risk of prostate cancer, researchers at the Oregon State University, Corvallis assessed the bioactive compound indole-3-carbinol against the onset of prostate cancer.
In vitro and in vivo. application of indole-3-carbinol inhibits prostate cancer by both blocking initiation and suppressing prostate cancer progression. these results were associated with the induction of phases I and II detoxification pathways.
Injection of indole-3-carbinol inhibited the cell signaling pathways associated with cancer cell proliferation and survival.
Recently, indole-3-carbinol derivatives induced cancer cytotoxicity through induction of free radical expression.
In the laboratory, I3C can induce G1 cell-cycle arrest and apoptosis in prostate cancer cells.
Furthermore, I3C and its derivative dimeric product 3,3'-diindolylmethane (DIM) inhibited the genes associated with the control of cell cycle, cell proliferation, signal transduction, and other cellular processes in prostate cancer cell lines.
Dr. Sarkar FH, the lead scientist, wrote in the final report of the experiment, "Because there is no effective treatment strategy for hormone-dependent and, most importantly, hormone-independent and metastatic prostate cancer, our strategies to sensitize prostate cancer cells to a chemotherapeutic agent by I3C and DIM is a novel breakthrough that could be used for devising novel therapies for prostate cancer".
More importantly, Wayne State University School of Medicine, in the study to confirm that a diet rich in fruits and vegetables provides phytochemicals, launched an investigation to examine the anticancer effect of indole-3-carbinol (I3C).
According to the study, I3C inhibits the growth of PC-3 prostate cancer cells
* through the Induction of G1 cell cycle arrest.
* Promoted the expression of regulators associated with cell cycle progression at G1 and S phase and proteins associated with cancer cell apoptosis.
* Inhibited proteins associated with the progression of cell cycle division
* Inhibited protein in the promotion of proteins associated with cancer cell cycle division.
Taken altogether, the plant base Indole-3-carbinol isolated from the cruciferous vegetable may be used for the prevention and treatment of prostate cancer with no side effects.
