To characterize the effects of Gilgyung-Tang(GGT) on cellular proliferation and viability of normal lung fibroblast cells, we examined the cell cycle progression and cell cycle-related gene expression in T3891 using a flow cytometry and a quantitative RT-PCR analysis. 1. The significant surpression effect of cellular proliferations of GGT was observed in proportion to a certain concentration and time. 2. GGT was identified to induce apoptotic death of damaged cells by treatment with a DNA-damage agent and etoposide, while it stimulated the recovery of cellular viability of normal cells. 3 The significant reductions of mRNA expression of PCAN, c-Fos treated by GGT were observed. 4. The significant inductions of mRNA expression of p53, CDKN1. Gadd45 treated by GGT were observed. 5. The apoptosis caused by the reduction of Bcl-2 genes was significant and the Bax genes were increased. but the amount of Fas genes were not changed. These results strongly suggest that GGT triggers arrest of the cell cycle at G1 phase, and thus causes an inhibition of cellular proliferation of human normal lung cells through the transcriptional up-regulation of cell cycle inhibitory genes and down-regulation of induction of cell cycle stimulating genes respectably.

Objectives: Gilgyung-tang (GGT) has been used as one of the main multi-herb formulas to treat “Peo-ong” (lung abscess). In this study, we investigated the inhibitory effects of water extracts of GGT on cell migration and invasion, two critical cellular processes that are often deregulated during metastasis, in human bladder cancer 5637 cells.Methods: Effects on cell viability were quantified using an MTT assay. To analyze the anti-metastatic effects, we conducted a wound healing migration assay, an in vitro invasiveness assay, and a measurement of the transepithelial electrical resistance (TER). The expression of protein and mRNA were measured by Western blotting and real-time polymerase chain reaction (RT-PCR), respectively.Results: GGT markedly inhibited the cell motility and invasiveness of 5637 cells within the concentration range that was not cytotoxic. The inhibitory effects of GGT on cell invasiveness were associated with tightening of the tight junctions (TJs), which was demonstrated by an increase in the TER. The RT-PCR and Western blotting results indicated that GGT decreased the levels of claudin proteins. GGT also inhibited the activity and expression of matrix metalloproteinase (MMP)-2 and -9 and simultaneously increased the levels of tissue inhibitor of metalloproteinase-1 and -2.Conclusions: Our findings suggest that GGT reduces both the migration and the invasion of 5637 cells by modulating the activity of TJs and MMPs.

Objective : In this study, we compared the antioxidant and anticancer properties of four multi-herbal formulas which were recorded in 'Dongeuibogam': Gilgyung-tang (GGT), Mokdanpi-tang (MDPT), Samso-eum (SSE), Samchulbobi-tang (SCBBT). Methods : We checked antioxidant properties of four multi-herbal formula through total phenolic content, radical scavenging activities, protective effects on genomic DNA oxidation. To investigate anticancer effects, we conducted MTT assay and analyzed morphologic change in A549 non-small lung cancer cells. Results : Total phenolic contents of four multi-herbal formulas were in a rich order of MDPT > SSE > GGT > SCBBT. Especially, MDPT revealed the highest activity than others in all antioxidant experiments. Our results indicated that treatment of those multi-herbal formulas induced growth retardation in A549 cells and MDPT also showed the highest anticancer effect ($IC_{50}=1.374mg/ml$) among them. Conclusions : Our data suggested that MDPT would be a powerful ingredient for lung cancer treatment.

In this study, we investigated the antioxidant activities and compared other physiological properties including anti-cancer and antimicrobial effects of several traditional Korean herb-combined remedies such as Gilgyung-tang (GGT), Daihwangmokdan-tang (DHMDT), Sagan-tang (SGT), Socheonryongtang (SCRT), Sihocheonggan-tang (SHCGT), Sipyukmiyuki-eum (SYMYKE) and Hwangheuk-san (HHS), which were recorded in “Dong-eui-bo-gam” for “Ongjeo”. Total phenolic contents of the herb medicines were in a rich order of GGT ＜ SYMYKE ＜ SCRT ＜ SHCGT ＜ DHMDT ＜ SGT ＜ HHS. Among them, HHS appeared highest in superoxide dismutase-like activity, ferric reducing antioxidant power, scavenging of 2,2’-diphenyl-1-picrylhydrazyl, and 2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonate) cationic radical activity. Interestingly, there was a positive relationship between their total phenolic contents and their antioxidant activities. Although all of them showed anti-proliferative activities in human colon cancer HCT-116 cells, HHS was seven times higher than GGT. Antimicrobial activities against Escherichia coli and Helicobacter pylori were revealed only on SGT, SCRT, SYMYKE and HHS. Taken together, these findings reveal the potential use of traditional Korean herbal formulas as functional ingredients in antioxidant and physiological materials.
