iNOS and PLA2 staining of MoCR cells cultured for 24 hours with CGP42112A at 0.1 or 1 μM in a background of either 0.1% FBS or 2% FBS. Representative images are shown below. Both iNOS and PLA2 staining was increased by CGP42112A treatment. Significant P values are shown with an * and solid line, while those of interest with P values between 0.1 and 0.05 are indicated with a dotted line and no *. Data are presented as mean ± S.E.M.
