Figure 3.

Expressions of p‐GSK‐3β in PC12 cells. Expression levels of p‐GSK‐3β were measured using double immunofluorescence staining. Mean fluorescence intensity was measured using ImageJ software. Quantitative results were expressed as mean ± standard deviation. Differences in these markers among the five groups were compared using one‐way ANOVA with LSD t test. ‘*’ indicates P < .05. Scale bar in Figure 3 is 5 μm
