αEnsa protein is upregulated and nuclear translocated in ischemic rat neurons.
Immunoperoxidase preparations reveal αEnsa protein upregulation in ischemic cortical
neurons, relative to control (A, upper row). Double label
immunofluorescent images demonstrate colocalization with NeuN in ischemic neurons with
nuclear translocation seen in zones 1 and 2 (A, rows 2–4, with yellow
merged images in lower row). Nuclear translocation of αEnsa is further demonstrated by
DAPI colabeling in zones 1 and 2 (B). Quantitative ROI analysis of
nuclear labeling is illustrated (C); scale bars,
10 µm (A) or 20 µm
(B); αEnsa, red/CY3; NeuN, green/FITC; nuclei, blue/DAPI.
