Mushrooms are known to complement chemotherapy and radiation therapy by countering the side-effects of cancer. Recently, a great deal of interest has been developed to isolate novel bioactive compounds from mushrooms because of their numerous health beneficial effects. Chemically water-extractable polysaccharide (MFKF-AP1β) was isolated from fruiting bodies of mushroom Fomes fomentarius. In this research, we investigated the anticancer effects of MFKF-AP1β on human lung carcinoma A549 cell. Results showed that MFKF-AP1β distinctly inhibited A549 cells growth in a dose-dependent manner and induced cell apoptosis evidenced by apoptosis assay. Besides that, MFKF-AP1β induced the LDH release and causes morphological alterations. Furthermore, the MFKF-AP1β (25.100 μg/ml) resulted in a significant single strand DNA breakage, on A549 cells as shown by comet assay. Taken together, our results demonstrate that MFKF-AP1β possesses strong antitumor activities through the induction of apoptosis. All these results suggested that MFKF-AP1β has evident anticancer activity through apoptotic induction.

Acrylamide (AA) is considered as a potential carcinogen by Food and Drug Administration (United States). AA is produced during the heating of starchy foods like potato chips, french fries, and coffee at high temperature and is regarded as a potential genotoxic carcinogen. However, a number of researches going on worldwide in the field of toxicology are concerned about the carcinogenicity of AA. Morin hydrate is a potent flavonoid compound. It is a yellow color substance that can be isolated from Maclura pomifera (Osage orange). So, in this study we have used morin hydrate to abolish the AA-induced toxicity by determining the variety of hematological, biochemical and immunological parameters in the serum, urine, liver and kidney of male mice. Subcutaneous injection of morin hydrate at a concentration of 5mg and 15mg kg-1 per day for 5 days along with 10mg kg-1 AA exposure could significantly reduce the toxicity of AA. As we found a significant reduction in the level of thiobarbituric reactive substances (TBARS) in tissue and serum, also, a significant reduction in antioxidant enzymes like superoxide dismutase (SOD), glutathione S transferase (GST), glutathione (GSH), myeloperoxidase (MPO) was observed. On the other hand, level of aspartate amino transferase (AST), alinine aminotransferase (ALT) in serum was found to decrease in a concentration dependent manner of morin hydrate. On the basis of the present study we conclude that morin hydrate can potentially protect renal and hepatic toxicity induced by AA.
