Figure Lengend Snippet: ErbB4 small molecule agonist can improve mitochondrial damage in hippocampal neurons of APP/PS1 mice. (A) The ultrastructure of hippocampal neuron mitochondria was examined using transmission electron microscopy. (B) Statistical analysis was conducted on data related to hippocampal neuron mitochondria. (C) Protein levels of the mitochondria-related proteins SIRT3 in hippocampal neurons were assessed using Western blot analysis. (D) Statistical analysis was conducted on the data obtained from these protein levels. (E) Levels of SIRT3 and β3-tubulin detected by immunofluorescence. SIRT3: red; β3-tubulin: green; scale bar = 20 ​μm. Tukey multiple comparative analyses were utilized. Magnification, 2000 ​× ​for mitochondrial structure; scale bar = 5 ​μm. The results were presented as means ​±SEM. Significance levels were denoted as ∗ p ​< ​0.05, ∗∗ p ​< ​0.01, and ∗∗∗ p ​< ​0.001, with a sample size of n ​= ​4–5 per group.

Article Snippet: Specifically, the sections were treated with a mouse anti-β3-tubulin antibody (1:100, sc80016, Santa Cruz Biotechnology, USA) in combination with the following antibodies: rabbit anti- p -ErbB4 antibody (1:200, bs-3220R, Bioss, Beijing, China), rabbit anti-SYP antibody (1:200, AF8091, Bioss, Beijing, China), rabbit anti-SIRT3 antibody (1:200, bs6105R, Bioss, Beijing, China), and rabbit anti-DOCK3 antibody (1:200, 20683-1-AP, Proteintech, Wuhan, China).

Figure Lengend Snippet: ErbB4 small molecule agonist improves hippocampal neuronal injury in AD pathologic state in vitro through ErbB4 pathway. (A–F) After treatment with Aβ1-42 at 10 ​μM for 12 ​h, hippocampal neurons were treated with C11H7BrO3 at a concentration of 10 ​nM for an additional 24 ​h. (A) Protein levels of the ErbB4 pathway-related proteins in hippocampal neurons were assessed using Western blot analysis. (B) A statistical representation of these protein levels was generated in a chart. (C) Protein levels of SIRT3, CREB and GAP43 in hippocampal neurons were assessed using Western blot analysis. (D) Statistical representation of these protein levels was generated in a chart. (E) Protein levels of PSD95, SYP, SYT1, and DOCK3 in hippocampal neurons were assessed using Western blot analysis. (F) Statistical representation of these protein levels was generated in a chart. Tukey multiple comparative analyses were conducted, with data reported as means ​± ​SEM. Significance levels were denoted as ∗ p ​< ​0.05, ∗∗ p ​< ​0.01, ∗∗∗ p ​< ​0.001. A minimum sample size of n ​= ​5–6 per group was utilized.

Figure Lengend Snippet: The ErbB4 small molecule agonist modulates DOCK3 to ameliorate hippocampal neuronal injury under AD pathological conditions in vitro. (A–H) After a 12 ​h exposure to 10 ​μM ​Aβ, the cells were transfected with either 50 ​nM si-NC or si-DOCK3 for 24 ​h. This was followed by a combined treatment with C11H7BrO3 at a concentration of 10 ​nM for an additional 24 ​h. (A) Protein levels of the ErbB4 pathway-related proteins in hippocampal neurons were assessed using Western blot analysis. (B) Statistical representation of these protein levels was generated in a chart. (C) Protein levels of DOCK3, CREB, SIRT3 in hippocampal neurons were assessed using Western blot analysis. (D) Statistical representation of these protein levels was generated in a chart. (E) Protein levels of the synapse proteins SYT1, GAP43, SYP, and PSD95 in hippocampal neurons were assessed using Western blot analysis.
