Figure 4. Sal promotes the growth of synaptic-associated proteins after OGD/R. (A–D) Protein expression and quantification analysis of PSD95, synapsin I and synaptotagmin in each group. (E) QPCR data for PSD95. Values are expressed as the mean ± SD. #p < 0.05, ##p < 0.01 vs. control; *p < 0.05, **p < 0.01 vs. OGD/R.
