| Popis: | 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 SNU484 gastric cancer cell lines. Oligonucleotide microarray approach were employed to screen the differential expression genes. Methods : CTF-HAS was prepared by boiling and stored at -70℃ until use. Cells were treated with various concentrations of CTF-HAS(0.1, 0.5, 1.5, 10, 20mg/㎖) for 24 h. Cytotoxicity was tested by MTT assay. To screen the differentially expressed genes in cancer cells, cells were treated with 1.5mg/㎖ of CTF-HAS. For oligonucleotide microarray assay, total RNA was used for gene expression analysis using oligonucleotide genechip (Human genome U133 Plus 2.0., Affimatrix Co.). Results : It has no cytotoxic effects on HepG2 cells in all concentrations (0.1, 0.5, 1.5, 10, 20mg/㎖). More than twofold up-regulated genes were 5 genes. The number of more than twofold down-regulated genes was 10. Discussion : This study showed the screening of CTF-HAS mediated differentially regulated genes using combined approaches of oligonucleotide microarray. The screened genes will be used for the better understanding in therapeutic effect of CTF-HAS on cancer field. |
