YiQiFuMai Powder Injection Protects against Ischemic Stroke via Inhibiting Neuronal Apoptosis and PKC<i>δ</i>/Drp1-Mediated Excessive Mitochondrial Fission

<div>YQFM suppresses translocation, expression and phosphorylation of Drp1 in I/R-injured rats. (a) Immunofluorescent staining of mitochondria and Drp1 in the cerebral cortex of ischemic hemisphere. Mitochondria were marked with ATP5A1 antibodies and nuclei were stained with DAPI. Bar = 5 <i>μ</i>m. (b) The colocalization of ATP5A1 with Drp1 was assessed on the basis of Manders’ overlap coefficients. Expression of Drp1 in the mitochondrial (c) and cytosolic (d) fractions. (e) Total levels of Drp1 and p-Drp1 (Ser616) in rat cerebral cortex of ischemic hemisphere. Results were expressed as mean ± SD from three independent experiments. <svg height="12.1645pt" id="M10" style="vertical-align:-0.6370001pt" version="1.1" viewbox="-0.0498162 -11.5275 54.2341 12.1645"
