초록

The effect of water extract of Chungjogupae-tang (CJGPT) was investigated _on the growth of human lung carcinoma A549 cells. Methods: MTT assay and fluorescent microscope peformed to compare and examine the efficacy of CJGPT treatment on the cytostaticity of lung cancer cells in proportion to time and doses, and DAPI staining and Western blot analysis were used to examine their effect on apoptosis. In addition, the quantitative RT-PCR was used to examine to lung cancer cells growth, and Prostaglandin E2 activity were measured. Results: Exposure of A549 cells to CJGPT respited in the growth inhibition and apoptosis in a dose-dependent manner as measured by MTT assay and fluorescent microscope. The antiproliferative effect by CJGPT treatment in A549 cells was associated with morphological changes such as membrane shrinking and cell rounding up. CJGPT treatment resulted in an up-regulation of cyclin-dependent kinase inhibitor p21 (WAFl/CIPl) in a p53-independent fashion. We found that CJGPT treatment decreased the levels of cyclooxygenase (COX)-2 and inducible nitric oxide synthease (iNOS) expression without significant changes in the expression of COX-1 , which was correlated with a decrease in prostaglandin E2 (PGE2) synthesis. Conclusion: These findings suggested that CJGPT-induced inhibition of human lung carcinoma A549 cell growth was connected with the induction of apoptotic cell death and the results provided important new insights into the possible molecular mechanisms of the anti-cancer activity of CJGPT.
