CYP and antioxidant enzyme expression level with CSC and LPV treatments. U937 cells were treated with either IFNγ + LPS or IL4+IL13+LPS to polarize to M1 or M2, respectively, for 48 h. Cells were then treated with CSC, LPV or CSC+LPV for 24 h. Each western blot data set shows a representative blot from three replicates. Blot density was normalized to the housekeeping protein and to the unstimulated control. (A) Western blot and densitometry for CYP 1B1expression. (B) Western blot and densitometry for CYP 2A6 expression. Blot density was normalized to the housekeeping protein and to the unstimulated control. (C) Western blot and densitometry for catalase expression. Blot density was normalized to the housekeeping protein and to the unstimulated control. (D) Western blot and densitometry for SOD2 expression. Blot density was normalized to the housekeeping protein and to the unstimulated control.
