Altered expression of NRF2-regulated genes in transformed HBEC lines exposed to Jamestown e-liquid. RT-qPCR for expression of SCARB1, SQSTM1, TXNRD1, ABCC4, HSPB8, PRKCE, DNAJC15, ENC1, JUN, SOD2, FTH1, and FTL in Jamestown transformed clones from HBEC2 and HBEC26 compared to air and normalized to β-actin. *p< 0.05, **p<0.01 compared to vehicle (n = 3).
