Fig. 5. |Effects of SNS on synaptic-associated protein in the HIP and PFC of stressed rats. Representative immunoblots for PSD-95, GAP-43, Syn, and Tublin in the HIP(A) and PFC(B) regions. (A) Results of relative protein levels of PSD-95, GAP-43, and Syn in the HIP of rats of each group.

Figure 3 Effect of iPSC-NPC-derived exosomes (OGD+iNPC-exo) on expression of the PTEN/AKT signaling pathway and of synaptic plasticity-related proteins in OGD induced neurons. (A–C) mRNA expression (A) and protein expression (B, C) of the PTEN/AKT signaling pathway and of synaptic plasticity-related proteins (NF200, GAP-43, Synapsin, and PSD95) analyzed by polymerase chain reaction and western blot assay. The mRNA expression is described by the optical density ratio relative to the control group. Protein expression was described by the optical density ratio relative to β-actin. Data are presented as mean ± SD. ***P < 0.001, vs. control group; ###P < 0.001 (one-way analysis of variance with post hoc Bonferroni test). All experiments were repeated three times. GAP43: growth associated protein 43; iPSC-NPCs: induced pluripotent stem cells-derived neural progenitor cells; NF200: neurofilament 200; OGD: oxygen-glucose deprivation; p-Akt: phosphor-Akt; PSD95: postsynaptic density protein 95; PTEN: phosphatase and tensin homolog deleted on chromosome ten.

Figure 5 MS reduces the expression of synaptic-plasticity protein. (A) The bands of synaptic-plasticity proteins of SYN, PSD-95, and GAP-43 in the hippocampus by WB. Statistical results indicate the relative protein levels expressed by SYN, GAP-43, and PSD-95. (B) The bands of synaptic-plasticity proteins of SYN, PSD-95, and GAP-43 in cortex by WB. Statistical results indicate the relative protein levels expressed by SYN, GAP-43, and PSD-95. Statistical analyses are performed by two-way ANOVA followed by t-test. Data are presented as mean ± SEM, *p < 0.05, **p < 0.01, n = 3 per group.

Figure 5 Western blot analysis. The expressions of synaptic plasticity proteins were determined by western blot (A), including PSD-95 (B), GAP-43 (C), and SYN (D). The values represent the mean ± SEM, n = 5. *p < 0.05, **p < 0.01 vs. CON, #p < 0.05, ##p < 0.01 vs. MS. CON, control; MS, maternal separation; CUMS, chronic unpredictable mild stress.

Figure 5 Iron related indexes and neural development of offspring rats after iron supplement treatment. Western blot analysis for FTL and Tf in liver (a–c) and spleen (d–f). Morris water maze test for day 1 escape latency (g) and day 2 escape latency (h). Western blot analysis for FTL and Tf in brain (i–k) and hippocampus (l–n), and for SYN1, NMDAR, PSD-95 in hippocampus (o–r). The quantification of western blotting was provided in supplementary material. FTL ferritin light chain, Tf transferrin, SYN1 synapsin 1, NMDAR N-methyl-D-aspartate receptor, PSD-95 postsynaptic density protein 95. Data of Western blot analysis (mean ± SD) are expressed as the ratio of the relative contents between the value from IDA group and NG group and six iron treatment groups (n = 3). The relative contents of target proteins were quantified using the ratio between the optical density (OD) of target protein and the amount of the housekeeping protein GAPDH. **p < 0.01, compared with NG, #p < 0.05, ##p < 0.01, compared with IDAG. One-way ANOVA followed by Tukey multiple comparison test was used for comparison among 8 different groups.

Fig. 4. The expression of PSD-95, SYN, and BDNF. Representative immunoblots of PSD-95, SYN, and BDNF in the cortex (A-D) and hippocampus (E-H) in each group. Protein immunoreactivity was normalized to -actin. Individual data are presented as the mean ± S.E.M. from 4 individual mice in each group.

(A) The expression of p-Tau and Tau in control rats and CUMS rats in the sixth week and tenth week of the CUMS period.(B) The expression of PSD-95 and SYN in control rats and CUMS rats in the sixth week and tenth week of the CUMS period. Bars represent mean ± S.E.M of the different groups (n = 3/group). (compared with control rats, *P < 0.05; **P < 0.01).
