Wogonin Inhibits Cardiac Hypertrophy by Activating Nrf-2-Mediated Antioxidant Responses

Figure 5

The cardioprotective effects of Wog involved in the modulation the Nrf-2-mediated antioxidant responses in vivo. (a–c) mRNA levels of Nrf-2 target genes Ho-1 and Nqo-1 as determined by qRT-PCR (); (d, e) immunohistochemical staining of heart tissues for Keap-1, the positive region with the red arrow; (f, g) heart lysates were probed for Keap-1 levels with Western blotting. GAPDH was used as the loading control (); (h) schematic diagram summarizes the molecular mechanisms by which Wog ameliorates cardiac hypertrophy by inhibiting oxidative stress. Wog as a promising natural agent, which protects against cardiac hypertrophy by activating the Nrf-2-mediated antioxidant responses. , , and compared to sham; , , and compared to TAC.
