We investigated changes in depression-like behaviors, social interaction, and cognition in SUMO1-KO mice compared to wild-type (WT) controls using the open-field test, tail suspension test, three-chamber test and novel object recognition test, respectively. To explore the underlying mechanisms of these behavioral differences, we performed Gene Ontology (GO) analysis of proteomics data and subsequently validated the findings through experimental verification. The results showed that SUMO1-KO mice exhibited increased risk-taking behavior, reduced depressive symptoms, and diminished novelty socialization compared to WT mice. Mass spectrometry-based proteomics analysis revealed 370 upregulated proteins and downregulated 84 proteins. GO annotation analysis identified significant enrichment of amino acid transmembrane transporter activities and ion channel. We further investigated two behavior-associated proteins, Hmox1 and Rpgrip1l, and validated their downregulated expression.

Unilateral common carotid artery occlusion (UCCAo) is a valuable model to simulate chronic cerebral hypoperfusion (CCH). This study explored UCCAo-induced CCH as a preconditioning stimulus to induce ischemic tolerance against transient global cerebral ischemia (tGCI) induced by bilateral common carotid artery occlusion (BCCAo) in both male and female mice. We evaluated the effects of CCH preconditioning on neuroprotection and recovery through behavioral, histopathological, and molecular analyses. Laser Doppler Imaging (LDI) confirmed significant cerebral hypoperfusion post-UCCAo. Preconditioning reduced mortality rates at days 1 and 7 post-surgery as compared to BCCAo, suggesting its neuroprotective potential. Neurodeficit scoring demonstrated significant protection in preconditioned animals with recovery aligning closer to sham controls. Behavioral assays revealed improved motor and cognitive outcomes in preconditioned groups, with sex-specific differences evident in recovery dynamics. Molecular analyses indicated reduced reactive astrocyte (GFAP) and microglial (IBA1) activation in preconditioned animals, reflecting controlled glial responses. Sex-dependent variations in markers of hypoxia (Hif1a), autophagy (Becn1), and neurogenesis (Sox2) highlighted neuroadaptive and cellular influences on ischemic resilience. Preconditioning enhanced synaptic plasticity by upregulating PSD-95, synaptophysin and BDNF levels.

The process of SCI is complex and has a long duration. Studies suggest that urocortin 2 (UCN2) is associated with motor functions regulated by the spinal cord. However, the role of electroacupuncture (EA) in regulating UCN2 at different times after SCI and its underlying molecular mechanisms remain unclear. The SCI animal model was established in SD rats by complete transection of the right spinal cord at the T10 level. EA was applied to the T9 and T11 Jiaji points. Behavioral analyses were performed at 1, 3, 7, 14 and 28 days post-injury (d.p.i.), and cellular morphology was observed in spinal cord tissue obtained from the injury site. RNA sequencing was carried out, and the results were validated. The use of EA significantly improved the behavioral scores and hind-limb locomotion in rats with SCI at 7, 14, and 28 d.p.i. (p < 0.05). At 3 d.p.i, the treatment resulted in a reduction in the number of astrocytes in the periphery of the injury site (p < 0.05), as well as a reduction in the extent of glial scar formation. Additionally, the number of microglia was increased, while neuronal apoptosis was suppressed (p < 0.05). At 14 and 28 d.p.i., the number of astrocytes was increased (p < 0.05), the number of microglia was decreased (p < 0.05), and the positive staining ratio of neurofilaments (NF) and myelin basic protein (MBP) was elevated (p < 0.05). Post-injury RNA sequencing showed that there were significant changes in UCN2 expression. The protein-protein interaction (PPI) network and KEGG enrichment analysis indicated a strong connection between UCN2 and the downstream cAMP-PKA signaling pathway. Subsequent qPCR, Western blotting, and immunohistochemistry experiments confirmed that EA significantly reduced the expression of UCN2, PKA, NF-κB, and NMDAR in rats with SCI at 1 and 3 d.p.i. (p < 0.05) while increasing the expression of UCN2, PKA, and CREB at 7, 14, and 28 d.p.i. (p < 0.05). By modulating UCN2, EA can activate the downstream cAMP-PKA signaling pathway. This process improves the presence of astrocytes and microglia around the injury site, inhibits neuronal apoptosis, and increases the number of myelin sheaths and NF.

Considerable research has focused on developing protein aggregation models to be explored as research tools. In the present work, four in vitro models for studying protein aggregation were studied and compared, namely treatment with: the toxic Aβ1-42 peptide, the isoflavone rotenone, the ATP synthase inhibitor oligomycin, and the proteosome inhibitor MG-132. All treatments result in aggregation-relevant events in the human neural SH-SY5Y cell line, but significant model-dependent differences were observed. In terms of promoting aggregate formation, Aβ and MG-132 provoked the greatest effect, but only MG-132 was associated with an increase in HSP-70 chaperone expression. In fact, the type of aggregates formed appear to be dependent on the treatment employed, and supports the hypothesis that Aβ exposure is a relevant AD model, and rotenone is a valid model for PD. Furthermore, the results revealed that protein phosphorylation is relevant to aggregate formation and as expected, tau co-localized to the deposits formed in the Aβ peptide aggregate induction cell model.
