| methanolic extracts of plocamium telfairiae induce cytotoxicity and caspase-dependent apoptosis in ht-29 human colon carcinoma cells. | natural marine products have recently become the focus of increased research interest, due to their potential pharmacological activities. therefore, we have screened 50 varieties of marine seaweed and determined that the methanolic extracts from plocamium telfairiae (pte) exhibited a cytotoxic effect against ht-29 human colon carcinoma cells. in this study, we report on the cytotoxic activity and mechanism of pte-induced apoptosis in ht-29 cells. the treatment of ht-29 cells with various pte con ... | 2007 | 18158827 |
