Luteolin Exerts Cardioprotective Effects through Improving Sarcoplasmic Reticulum Ca²⁺-ATPase Activity in Rats during Ischemia/Reperfusion In Vivo

Figure 4

Luteolin alleviates I/R-induced decrease of SERCA2a activity. SERCA2a activities of all sham groups were expressed as 100%, and the other groups were normalized to the corresponding sham groups. This figure was split by different reperfusion duration of 12 h and 1 d. The first half consists of 0 min, 30 min, 60 min, 120 min, 6 h, and 12 h of reperfusion time points. The last half contains 12 h, 1 d, 3 d, 5 d, and 7 d of reperfusion time points. The results are expressed as mean ± SD, . , versus 30 min/0 min groups; versus 30 min/60 min groups; , versus 30 min/12 h groups; versus 30 min/1 d group.
