Figure 5.
Berberine (BBR) can increase the number of autophagosomes in myocardial ischemia-reperfusion injury (MIRI) model rats subjected to ischemia/reperfusion (I/R). Autophagosomes were detected in MIRI model rats pretreated with shBNIP3/shNC and BBR (50 μM) by transmission electron microscopy (TEM). Scale bar = 200.0 nm (insets) and magnification 120,000×. (B). Quantification of the autophagosomes from different groups is presented as bar graphs. The figures are representative images of three different rats. The data are the means ± SD (n=3). *P < 0.05 compared to the sham group; #P < 0.05 compared to the I/R group; &P < 0.05 compared to the BBR+I/R group.
