2019 AUG 08 (NewsRx) -- By a News Reporter-Staff News Editor at Japan Daily Report -- Investigators publish new report on Oncology - Prostate Cancer. According to news reporting out of Gunma, Japan, by NewsRx editors, research stated, “The reoccurrence of androgen-dependent prostate cancer after anti-androgen therapy mainly depends on prostate cancer stem-like cells. To reduce the risk, it is important to delete the cancer stem-like cells.”
Financial support for this research came from (Inoue Enryo Memorial Foundation of Toyo University).
Our news journalists obtained a quote from the research from Toyo University, “Furthermore, to induce differentiation of cancer stem-like cells is critical to abrogate stemness of the cells. Therefore, we tried to investigate a possibility on the establishment of a new effective therapy to eradicate the cancer stem-like cells via the induction of differentiation in this study. Prostate cancer stem-like cells from an androgen-dependent prostate cancer cell line (LNCaP cell) had severe resistance against an anti-androgen therapeutic agent. We selected Bowman-Birk inhibitor (BBI) from soybeans reported as a chemopreventive agent in prostate cancer to differentiate the caner stem-like cells and a-tocopheryl succinate (TOS) known as a mitocan to induce effectively cytotoxic effect against the cancer stem-like cells. In fact, only TOS treatment had cytotoxic effect against the cancer stem-like cells, but the addition of BBI treatment to the cells treated with TOS reinforced TOS-mediated cytotoxicity in the cancer stem-like cells. This reinforcement coincided with the combination-enhanced apoptosis in the stem-like cells. Also, we confirmed caspase9-caspase3 cascade mainly contributed to the enhancement of the cytotoxicity in the stem-like cells caused by the combination, indicating that the reinforcement of BBI on TOS-mediated apoptosis via mitochondria related to the enhancing cytotoxic effect of the combination on the prostate cancer stem-like cells.”
According to the news editors, the research concluded: “Overall, it seems that the combination is an effective new approach to reduce the reoccurrence of prostate cancer targeting prostate cancer stem cells.”
