Abstract: Methanol extracts of five commercially available mushroom species (Phellinus linteus (Berk. et Curt) Teng, Cordyceps sinensis (Berk.) Sacc., Lentinus edodes (Berk.) Pegler, Coprinus comatus (O. F. Müll.) Pers. and Ganoderma lucidum (Curtis) P. Karst), traditionally used as anticancer agents, were evaluated in vitro for their total phenol and flavonoid contents, cytotoxic and antimigratory activities and antioxidant/prooxidant effects on colon cancer cell lines (HCT-116 and SW-480). Spectrophotometric methods were used for the determination of total phenol content, flavonoid concentrations and DPPH activity of the extracts. Cytotoxic activity was measured by the MTT assay. The antimigratory activity of extracts was determined using the Transwell assay and immunofluorescence staining of ß-catenin. The prooxidant/antioxidant status was followed by measuring the superoxide anion radical (O2•-), nitrite and reduced glutathione (GSH) concentrations. Our results show that the highest phenolic and flavonoid content was found in P. linteus, and its DPPH-scavenging capacity was significantly higher than in other samples. The P. linteus extract significantly decreased cell viability of both tested cancer cell lines. All other extracts selectively inhibited SW-480 cell viability, but did not show significant cytotoxic activity. The mushroom extracts caused changes in the prooxidant/antioxidant status of cells, inducing oxidative stress. All extracts tested on HCT-116 cells demonstrated significant antimigratory effects, which correlated with increased production of O2•- and a reduced level of ß-catenin protein expression, while only P. linteus showed the same effect on SW-480 cells. The results of the present research indicate that the mushroom extracts causes oxidative stress which has a pronounced impact on the migratory status of colon cancer cell lines.
