Effect of Tan IIA on Nrf2 mRNA and its downstream genes expression in DOX-treated mice heart. The mRNA expression of (A) Nrf2, and its downstream genes, including (B) HO-1, (C) NQO1, (D) GCLC, (E) MRP2 and (F) P-gp were determined by reverse transcription-quantitative polymerase chain reaction. Data are presented as the mean ± standard error of the mean (n=6). *P<0.05, **P<0.01 and ***P<0.001 vs. the control; #P<0.05, ##P<0.01 and ###P<0.001 vs. DOX. Tan IIA, tanshinone IIA; Nrf2, nuclear factor (erythroid-derived 2)-like 2; DOX, doxorubicin; HO-1, heme oxygenase-1; NQO1, NAD(P)H dehydrogenase (quinone) 1; GCLC, glutamate-cysteine ligase catalytic subunit; MRP2, multidrug resistance-associated protein 2; P-gp, P-glycoprotein.
