Objective : It has long been known about the osteogenic effect of CTF-HAS on bone tissues. However, it has not been determined the effect of CTF-HAS on cancer cells. The purpose of this study is to screen the CTF-HAS mediated differentially expressed genes in cancer cells such as HepG2 hepatoma cells lines. Methods : CTF-HAS was prepared by boiling and stored at $-70^{circ}C$ until use. For proteomic analysis, total protein was analyzed by 2D gel electrophoresis and Q-TOF mass spectrometer. Results : In proteomic analysis, three spots were identified by 2D-gel electrophoresis and Q-TOF analysis. One down-regulated protein was heat shock 70kDa protein 5 and up-regulated proteins were chaperonin and 2-phospho -pyruvate-hydratase ${alpha}-enolase$ by 1.5mg/ml of CTF-HAS. Discussion : Proteomic analysis approach were performed to screen the differential expression genes. The screened genes will be used for the better understanding in therapeutic effect of CTF-HAS on cancer field.
