【Abstract】 AIM: To study the anti cancer activity of high grade unsaturated fatty acids from Isatis tinctoria L on BEL 7402 human hepatocellular carcinoma cell in vitro . METHODS: Cytotoxicity assay was tested by MTT method. The proliferation of BEL 7402 cells was observed by colony forming units assay. Telomerase activity in cell was determined by PCR ELISA method. RESULTS: IC 50 of unsaturated fatty acids from Isatis tinctoria L on BEL 7402 cell line was 0 6 mg·mL -1 . Telomerase activity was dramatically declined during the cell incubation with unsaturated fatty acids. Unsaturated fatty acids can induce the BEL 7402 cells to reverse normal cells. CONCLUSION: Unsaturated fatty acids from Insatis tinctoria L possesses anti tumor activity in vitro .更多还原
