Effects of exogenous DOX on TGF-β1 expression on 7-day cultures of EaRASMCs subject to 30 minutes of cytokine injury. TGF-β1 levels were measured using ELISA. RASMC healthy cell controls and DOX-treated cytokine activated EaRASMCs are presented as normalized to the DOX-free, cytokine-activated EaRASMCs (treatment controls) (n = 3 per group; mean ± st. error). * denotes p < 0.05 compared to RASMC healthy cell controls; $ denotes p < 0.05 compared to treatment control; % denotes p < 0.05 compared to 0.1 μg/mL DOX-treated cultures
