COX-2 expression was inhibited by LV-COX-2siRNAi-1 in SaOS2 cells. (A) SaOS2 cells infected with LV-Control and LV-COX-2siRNAi-1. GFP expressed 48 h after the infection (magnification 40 ×). COX-2 (B), but not COX-1 (C) mRNA level was significantly inhibited by LV-COX-2siRNAi-1. Data are presented as mean ± s.e.m. # P < 0.001, compared with LV-Control and parental SaOS2 cell group.
