마이크로어레이를 이용한 봉독 처리된 돼지 초대배양 연골세포에서의 유전자 발현 프로파일링

Osteoarthritis is one of the commonest causes associated with age-related damage of articular cartilage. Non-steroidal anti-inflammatory drugs are commonly used in osteoarthritic patient. However, long term administration of these drugs results gastrointestinal disorders. Though, most studies have demonstrated in the past that bee venom has therapeutic effect on diseases related to inflammation and pains, but its anti-inflammatory properties have not been so far studied on inflamed chondrocytes (LPS induced) invitro. For the purpose, the study was carried out to determine the effect of bee venom on porcine articular chondrocyte cell using microarray. In this study, we found that 2,235 significantly associated gene (1,404 up-regulated genes and 831 down-regulated genes) that were expressed on inflamed and non inflamed chondrocytes during proliferation. Among the 1,404 up-regulated genes and 831 down-regulated genes, known genes were 372 and 237, respectively. On the other hand, bee venom significantly reduced expression of fetuin involved in acute inflammatory reaction. Our results suggest that this study could be useful database in gene expression profiling of chondrocyte cell treated with bee venom.
