초록

홍삼추출액의 신경성체줄기세포 성장과 생존에 미치는 영향을 분석하고자 human neuronal stem cell line인 F3 cell을 배양한 후 홍삼추출액을 여러 농도로 희석하여 MTT assay로 cell viability를 측정하였고 FACS analysis로 cell Cycle변화를 측정하였다. 특정한 농도에서는 세포가 증식되는 경향을 보였으며 농도가 증가되면서 viability가 감소되는 현상을 확인할 수 있었다. Cell cycle 분석상 세포증식시에는 5 phase 및 G2/M phase가 증가되는 경향을 보였고, viability가 감소되면서 S phase가 감소되고 G0/G1 phase 가 증가 되었다. 한편 DNA fragmentation이 cell viability감소에 따라 증가되었으나, Caspase 3 activation 또는 Bax expression과는 관련성이 적었다.

The present study is to determine whether the Red-ginseng extract has a proliferative or cytotoxic effect on the human neuronal stem cells(hNSCs). The hNSCs were grown and incubated with different doses of Red-ginseng extract. We tested the proliferative or cytotoxic effects by MTT and FACS analysis. Cell viability cell cycle analysis, DNA fragmentation, and bax or PARP expressions were evaluated. The hNSCs showed a proliferafe trend with its peak concentration at 0.3 $\mu\textrm{g}$/$m\ell$. Beyond this point, higher doses decreased viabilities and showed a cytotoxic effect at 10 $\mu\textrm{g}$/$m\ell$. There was a tendency of increased S and G2/M phases during cell proliferation. In a cytotoxic condition, decreased S phase and increased G0/G1 phases were noted, suggesting cell cycle arrest. The cytotoxic effect was associated with increase DNA fragmentation in a dose-dependent manner, However PARP cleavage or bax expression was not detected. Our results suggest that Red-ginseng extract has dual effects, the cell proliferative or cytotoxic effect, on hNSCs in vitro with dose-dependent manner.
