Purpose : Growth inhibitory effects of lipid soluble components of the Korean red
ginseng and the antineoplastic mechanism against human melanoma cell lines were
investigated. To examine molecular mechanism of growth inhibitory effects of GX-PE,
we analyzed the effect of GX-PE on cell cycle progression and expression of cell cycle
regulatory factors such as retinoblastoma gene product (Rb), p27Kipl,
p21WAF1, cdk2, cdk4 and cyclic D1 which are known to regulate cell
cycle progression.
Materials and Methods : Petroleum ether extract of the Korean red ginseng (GX-PE)
was added to cultures of three human melanoma cell lines, SK-MEL-1, SK-MEL-2, and
SK-MEL-5. Proliferation was measured by 3H-thymidine incorporation
assay. Cell cycle and expression of cell cycle regulatory factors were analyzed by flow
cytometry and Western blotting, respectively.
Results : Growth of melanoma cells was inhibited by GX-PE in proportion to the
concentration. GX-PE significantly inhibited cell cycle progression at Gl phase. GX-PE
increased expression of negative cell cycle regulators, i.e., p27Kipl in
SK-MEL-2 and p21WAF1 and Rb in SK-MEL-1.
Conclusion : These results suggest that GX-PE inhibits proliferation of melanoma
cells at a G1-S transition point of the cell cycle. The effect of GX-PE is most likely
due to induction of negative cell cycle regulatory factors.
