Mushrooms have been used as food or medicine for thousands of years. Due to low-fat content and absence of cholesterol, many mushrooms are excellent sources of protein. There are various mushroom proteins with interesting biological activities, such as lectins, fungal immunomodulatory proteins (FIP), ribosome inactivating proteins (RIP), ribonucleases,(More)
Lentinus edodes has been valued as edible and medical resources. Polysaccharides have been known to be the most potent antitumor and immunomodulating substance in Lentinus edodes. In this review, we summarize the current knowledge of the polysaccharides isolated from Lentinus edodes, including extraction and purification methods, chemical structure and(More)
Lung cancer is still difficult to treat by current chemotherapeutic procedures. We recently found that MVL, an anti-HIV lectin from blue-green algae Microcystis viridis, also has antitumor activity. The objective of this study was to investigate apoptosis-inducing activity of recombinant MVL (R-MVL) and proteomic changes in A549 cells, and to identify the(More)
Isothiocyanates (ITCs) have been shown to possess antitumor activity in colon cancer, however, the detailed mechanism is still unclear. The objective of this study was to investigate apoptosis-inducing activity of ITCs from Broccolini seeds and proteomic changes in SW480 cells, and to identify the molecular pathways responsible for the anticancer action of(More)
Polysaccharide is a major bioactive component of mushrooms. In this study, for the first time, starting from a new Lentinula edodes polysaccharide L2, we prepared a novel L2-calcium complex and the process was optimized. Scanning electron microscopy and Fourier Transform infrared spectrometry were used for characterization. The immunostimulating activities(More)
In this study, a new heteropolysaccharide, here called L2, was separated from the fruit body of Lentinula edodes. Chemical and physical analyses indicated that L2 has a molecular weight of 26 KDa and consists of glucose (87.5%), galactose (9.6%), and arabinose (2.8%), but it does not possess a triple-helical conformation. Stimulation of the production of(More)
