Chronic Sulforaphane Application Does Not Induce Resistance in Renal Cell Carcinoma Cells.
Background/aim Since the natural compound sulforaphane (SFN) has been shown to stop tumor growth, renal cell carcinoma (RCC) patients often use this drug in addition to their prescribed oncotherapy. The aim of this study was to examine whether resistance to SFN may develop after long-term application. Materials and methods Several RCC cell lines were incubated with SFN for short periods of time (24-72 h) or long periods of time (8 weeks) and cell growth, proliferation, and cell-cycle proteins were analyzed. Results Both short- and long-term application of SFN distinctly reduced RCC cell growth and proliferation. However, differences in the distribution of cells in each phase of the cell cyc…
Relevance of the natural HDAC inhibitor sulforaphane as a chemopreventive agent in urologic tumors.
Due to an increased understanding of molecular biology and the genomics of cancer, new and potent agents have been approved by the Food and Drug Administration (FDA) to fight this disease. However, all of these drugs cause severe side effects and resistance inevitably develops, re-activating tumor growth and dissemination. For this reason, patients turn to natural compounds as alternative or complementary treatment options, since it has been found that natural plant products may block, inhibit, or reverse cancer development. The present review focusses on the role of the natural compound sulforaphane (SFN) as an anti-tumor agent in urologic cancer. SFN is a natural compound found in crucife…
In vitro pro-apoptotic and anti-migratory effects of Treculia africana Decne. (Moraceae) and Entandrophragma angolense Welw (Meliaceae) extracts on prostate cancer cells
Abstract Prostate cancer is the second leading cause of cancer deaths in men and there is an increasing interest in chemoprevention to fight it. The authors sought a scientific rationale for the traditional use of six Cameroonian medicinal plants for the treatment of prostate inflammation/tumour. The prostate cells viability incubated with each ethanolic plant extract was determined after 24, 48 and 72 h using the MTT assay. The antitumor mechanisms of promising extracts [Treculia africana (TA) and Entandrophragma angolense (EA)] were further assessed by evaluating cell growth, cell proliferation, cell cycle, cell death mechanisms and cell migration. Only TA and EA significantly inhibited L…
