Lentinula edodes, known as ‘‘shiitake’’ is one of the widely used medicinal mushrooms in the Orient. Antitumour activity of extracts of this mushroom has been widely demonstrated in animals and humans. However, this activity was shown to be host mediated and not by direct cytotoxic activity to cancer cells. This study demonstrates cytotoxic and cell growth inhibitory (cytostatic) effect of aqueous extracts of the mushroom on MCF-7 human breast adenocarcinoma cell line using an MTT cytotoxicity assay. Such effect was demonstrated with fruit body and mycelial extracts, the difference being that there was no significant suppression on normal cells with the latter. Furthermore mycelial extracts did. | Available online at ScienceDirect Phytomedicine 15 2008 512-519 Phytomedicine phymed In vitro cytostatic and immunomodulatory properties of the medicinal mushroom Lentinula edodes CTc VQ Ỉ11 Ha c Q cb A rn nn rrlnila A PhlllT WXr Ml Q ci CC f T Pro f ciT1Ỉ cb .

Antitumour activity of extracts of this mushroom has been widely demonstrated in animals and humans. However this activity was shown to be host mediated and not by direct cytotoxic activity to cancer cells. This study demonstrates cytotoxic and cell growth inhibitory cytostatic effect of aqueous extracts of the mushroom on MCF-7 human breast adenocarcinoma cell line using an MTT cytotoxicity assay. Such effect was demonstrated with fruit body and mycelial extracts the difference being that there was no significant suppression on normal cells with the latter. Furthermore mycelial extracts did not induce any cytostatic effect in both cancer and normal cell lines based on a DNA synthesis assay. The significant suppression of the proliferation of cancer cells was reflected by the comparatively low IC50 values .
