Effects of AhR antagonist, CH223191, on responses to PCB126 or IS A Preadipocytes were treated with vehicle or CH223191 (8 μM) along with vehicle or PCB126 at concentrations of 2 or 10 μM for 4 days after the PCB126 was removed followed by differentiation for 13 days. Differentiated adipocytes were treated with norepinephrine at 10 μM for 6 hours in media without serum after which the cells were collected for RNA and assessed for UCP1 transcript levels as described in the Materials and Methods. Transcript levels were normalized to GAPDH. Shown values are fold-changes over non-stimulated (no NE) controls. B. Preadipocytes were treated with vehicle or CH223191 (8 μM) along with vehicle or IS at concentrations of 10 or 50 μM for 4 days after the PCB126 was removed followed by differentiation for 13 days. Fold changes in NE-induced UCP1 induction were assessed as in A. Statistical analysis was performed using the GraphPad Prism program and 2-way ANOVA with Sidak’s multiple comparison test (* p<0.05; **** p<0.0001; ns=nonsignificant).
