摘要：

Since oxygen free radicals are believed to play an important role in cartilage degradation, we studied the effects of these radicals generated by the hypoxanthine-xanthine oxidase system on rabbit articular chondrocytes in culture. Among the damages induced by these radicals, cell proliferation inhibition and G2 arrest were observed. To elucidate the mechanisms involved in this phenomenon, the expression of c-myc and c-Ha-ras genes whose products are associated with cell growth control was studied. Results showed that in chondrocytes, c-myc and c-Ha-ras expression was particularly important during the G1 phase of the cell cycle and that oxygen reactive species, especially H2O2, induced an important decrease of c-myc and c-Ha-ras mRNA levels. Chondrocytes cell cycle analysis revealed an accumulation of cells in G2 phase. It led us to suggest that the chondrocyte cell cycle perturbations observed after oxygen free radicals treatment could be associated with the decrease of c-myc and c-Ha-ras expression. © 1991.
