This study evaluated the anti-glioma potential of selected mushrooms on glioblastoma cells, and found that ethanol extracts showed stronger activity compared to aqueous extracts. The mechanisms of action included inhibition of cell proliferation, induction of apoptosis, and suppression of metalloproteinase activity, with L. deliciosus and C. comatus demonstrating the greatest anti-glioma potential among the investigated mushrooms.
Cancer incidence rates are on the increase worldwide. The most common brain cancer in adults is glioblastoma. Currently available treatment modalities are limited and natural products such as mushrooms could enhance them. Apart from nutritional value, mushrooms are an excellent source of bioactive compounds and therefore could be used to treat various disorders. The aim of the study was to assess the anti-glioma potential of selected mushrooms on U87MG, LN-18 glioblastoma and SVGp12 normal human astroglial cell lines. The materials were Cantharellus cibarius, Coprinus comatus, Lycoperdon perlatum and Lactarius delicious. Aqueous, 70 % ethanol or 95 % ethanol extracts from mushrooms were used for analysis including assessment of antioxidant activity by DPPH assay, cell viability by MTT assay, DNA biosynthesis by thymidine incorporation assay, activity of metalloproteinase by gelatin zymography and cell cycle assay by flow cytometry. Mushroom extracts influenced the viability and DNA biosynthesis of cancer cells. Activity of ethanol mushroom extracts was stronger than that of aqueous extracts. Anti-glioma mechanism consisted in inhibition of cancer cell proliferation and induction of apoptosis associated with arrest of cells in subG1 or G2/M phase of cell cycle, and inhibition of metal-loproteinases activity. Among investigated mushrooms, L. deliciosus and C. comatus showed the greatest anti-glioma potential.
