Abstract:
Objective: The antitumor mechanism of Pleurotes sapidus on 4 kinds of tumor cell lines was studied. The active components of its ethanol extracts were studied. Methods:Using techniques of cell culture in vitro, phytochemical methods, FACS and RT-PCR, expressions of p53 and fas gene of four tumor cell lines treated with Pleurotas sapidu were analysed. Results:The apoptosis rates were remarkably increased after treated by ethanol extracts (0.1g/ml) and water extracts (0.1g/ml) for 12 h and 24 h respectively. The expression of P53 protein in the groups of ethanol and water extracts were significantly increased, and the gene expressions of p53 and fas were aslo highly up-regulated. Conclusion:The antitumor effect of Pleurotas sapidus on tumor cell lines in vitro is evident, and its mechanisms are probably associated with the regulation of apoptosis by inducing the gene expressions related to apoptosis.
