인간 전립선암 PC-3 세포에서 Compound K에 의한 세포주기 조절 및 세포사멸 유전자 발현 변화

초록

Objectives : Previously, we reported that compound K isolated from fermented ginseng by Aspillus oryzae has a wide biochemical and pharmacological effect, including anti-cancer activity in prostate cancer PC-3 cells. Despite these findings, its signaling pathway and gene expression pattern are not clearly understood. Methods : To confirm the gene expression study of treated with compound K in PC-3 cells, a cDNA microarray chip composed of 44K human cDNA probes was used. MTT assay, western blot analysis, propidium iodide staining, and annexin V/propidium iodide staining were analyzed. Results : We confirmed the differences of gene expression profiles. Then, we analyzed with the cell cycle arrest, cell death and cell proliferation related genes using DAVID database. Conclusions : Our finding should be useful for understanding genome-wide expression patterns of compound K-mediated cell cycle arrest toward induction of cell death and be helpful for finding future cancer therapeutic targets for prostate cancer cells.
