Polyozellus multiplex, a Korean wild mushroom, was extracted using methanol, and the extract was further fractionated with water and ethylacetate. Assay of each fraction with MTT revealed significant tumoristatic effects of the water fraction of Polyozellus multiplex against human gastric and other cancer cells but not normal human lymphocytes. Modifying effects of the water fraction on glandular stomach mucosa were investigated in male Wistar rats treated with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG). The dietary 0.5% or 1% water fraction of Polyozellus multiplex significantly increased glutathione S-transferase (GST) and superoxide dismutase (SOD) activities, and showed a tendency for increase in glutathione (GSH) levels, compared to the MNNG alone group. It also caused a significant reduction in proliferating cell nuclear antigen (PCNA)-labeling index of the glandular stomach epithelium, along with increase in p53 tumor suppressor gene expression. These results suggest that Polyozellus multiplex is a candidate for chemoprevention against gastric cancer.
