The Anti-Inflammatory Effect of IH-901 in HT-29 Cells

다국어 초록 (Multilingual Abstract)

20-O-($\beta$-D-Glucopyranosyl)-20 (S)-protopanaxadiol (IH-901) is one of the major metabolites of ginsenosides from Panax ginseng, and is suggested that IH-901 has been associated with various pharmacological and physiological activities. In this study, we demonstrate that IH-901 induced anti-inflammation in HT-29 human colon adenocarcinoma cells. Our results showed that IH-901 inhibited cell proliferation of HT-29 in a time- and dose-dependent manner. We also found that IH-901 was significantly decreased expression of iNOS compared with non-treated. We observed effect of IH-901 related with inflammatory genes using by cDNA microarray. We were known that the 34 inflammatory genes such as E2F, CDK6, TNF-$\alpha$, and PKC were down-regulated. Thus, these results suggest that IH-901 may have a potential preventive factor to improving cancer induced by chronic inflammation.
