title: Gypenoside induces apoptosis in human Hep3B and HA22T tumour cells.
abstract: The effect of gypenoside, an active component of the Chinese herb Gynostemma pentaphyllum (Thumb) Makino, on human hepatoma cell lines (Hep3B and HA22T) was investigated. Results demonstrated that gypenoside inhibited the proliferation or viability of the Hep3B and HA22T cells in a dose-dependent manner. The Hep3B and HA22T cells treated with gypenoside for 2 days were less DNA stainable and formed a sub-G1 peak. The treated cells increased cell numbers in the A0 region as well as shifting the ordinary S phase to the final S phase (D1 region), and induced a ladder pattern of fragmented DNA of about 200 base pairs. These data suggest that the cell death of the hepatoma cell lines Hep3B and HA22T induced by gypenoside was via apoptosis, and this was confirmed by morphological studies.
