Concentrations of membrane-bound β2AR in human airway smooth muscle (HASM) cells treated with the indicated concentrations of PAHs for 24 hours. The expression of protein was quantified according to the immunoblot band density, which was then normalized to same-sample actin band density. Control cells were treated with the indicated concentrations of DMSO in complete medium for 24 hours (n = 6 dishes/condition). *P = 0.04, versus control HASM cells treated with 10% DMSO vehicle.
