| Outline of Final Research Achievements |
Detection of miRNAs control cytokine induced aggrecanase We detected several miRNA s using miRNA array technique.Long term hyaluronan (HA) treatment reduced cartilage destruction, significantly, but its protection was limited.We revealed mechanical stress did not change HA receptor genes CD44 and ICAM1 mRNA expression level in chondrosarcoma cell line OUMS-27.Weak mechanical stress induced cartilage matrix proteins, both aggerecan and type 2 collagen in OUMS-27.
