Rabbit meniscus cells were administrated with different concentrations of levofloxacin. After treatment with levofloxacin for 48 h, cells viability was decreased and apoptotic cells increased. Meanwhile, active caspase-3 protein expression level was also increased and mRNA expression level of Bcl-2 decreased. Both mRNA and protein expression levels of MMP-3 and MMP-13 increased. Besides, the mRNA expression levels of TIMP-3 and col1a1 were decreased, while that of iNOS increased. Thus, levofloxacin induced apoptosis and unbalanced MMPs/TIMPs expression in meniscus cells.
