Selective ATP-Binding Cassette Subfamily C Gene Expression and Proinflammatory Mediators Released by BEAS-2B after PM2.5, Budesonide, and Cotreated Exposures

BEAS-2B respond to PM2.5 organic extracts. Local particle pollution has the capacity to generate ROS triggering the activation of Nrf2 and inducing the synthesis of antioxidant mRNAs: HMOX1 (heme oxygenase 1) and GSTP1 (glutathione-S-transferase). The antioxidant capacity is reduced provoking oxidative stress and the synthesis of ABCC1 and 4 and IL-6 and IL-8 mRNAs and their respective proteins.
