BackgroundSchizophrenia is a complex, chronic and severe mental disorder, and the pathogenesis of which has not been fully elucidated. The abnormalities in lipid metabolism and circulating metabolomes have already been implicated in the pathophysiology of schizophrenia. However, available studies have mainly focused on a few liposomes and circulating metabolites, failing to systematically reveal the mediating role of circulating metabolomes in the causal relationship between liposomes and schizophrenia. ObjectiveTo uncover mediating role of circulating metabolomes in the causal relationship between liposomes and schizophrenia, thereby providing biomarkers and potential therapeutic targets for the prevention and treatment of schizophrenia. MethodsData from Genome-Wide Association Studies (GWAS) were analyzed, taking data on 179 liposomes as exposure variables, data on 123 circulating metabolites as intermediate variables, and data on schizophrenia as outcome variable. A two-step, two-sample Mendelian randomization analysis was conducted using the inverse-variance weighted (IVW), MR- Egger, Weighted median, and Weighted mode methods to study the causal relationship of liposomes with schizophrenia and the mediating role of circulating metabolomes in the relationship. ResultsIVW model identified 8 lipids associated with schizophrenia without reverse causality. There were 5 circulating metabolomes strongly associated with schizophrenia. Acetate played a significant mediating role in the causal relationship between phosphatidylinositol (18:0_18:2) and schizophrenia (P=0.023, 95% CI: 0.036~0.532), accounting for 28.4% of the causal relationship. ConclusionThis study demonstrates a causal relationship between liposomes and schizophrenia, with phosphatidylinositol being a risk factor in the progression of schizophrenia, and acetate playing a mediating role in this process.

Objective To investigate the therapeutic effect of Euryale ferox seed shell extract on oral ulcer in rats and its underlying mechanism. Methods The contents of polyphenols and flavonoids in Euryale ferox seed shells were determined by Folin-phenol assay and aluminum nitrate colorimetry, respectively. DPPH · , ABTS+· , · OH and · O2- scavenging experiments were performed to evaluate the antioxidant activities of Euryale ferox seed shell extract in vitro. In a rat model of oral ulcer induced by burning with glacial acetic acid, the therapeutic effect of Euryale ferox seed shell extract was assessed by detecting changes in serum levels of oxidative factors by enzyme-linked immunosorbent assay (ELISA) and observing pathological changes of the ulcerous mucosa using HE staining; the therapeutic mechanism of the extract was explored by detecting the expression levels of Keap1, Nrf2, Nes-Nrf2 and HO-1 proteins in ulcerous mucosa using Western blotting. Results The ethyl acetate extract of Euryale ferox seed shells contained 306.74±1.04 mg/g polyphenols and 23.43±0.61 mg/g flavonoids and had IC50 values for scavenging DPPH · and ABTS+· free radicals of 3.42 ± 0.97 μg/mL and 3.32 ± 0.90 μg/mL, respectively. In the rat models, the ethyl acetate extract significantly ameliorated oral mucosal ulcer, increased serum CAT level, and decreased serum MDA level. The protein expression levels of Nes-Nrf2 and HO-1 were increased and Keap1 protein expression was lowered significantly in the ulcerous mucosa of the rats after treatment with the extract (P<0.05 or 0.01). Conclusion The therapeutic effect of Euryale ferox seed shell extract on oral ulcers in rats is mediated probably by activation of the Keap1/Nrf2/HO-1 signaling pathway.
10.Conbercept reverses TGF-β2-induced epithelial-mesenchymal transition in human lens epithelial cells by regulating the TGF-β/Smad signaling pathway
Journal of Southern Medical University 2024;44(8):1459-1466
Objective To investigate the mechanism by which conbercept reverses transforming growth factor-β2(TGF-β2)-induced epithelial-mesenchymal transition(EMT)in human lens epithelial cells(HLECs).Methods Cultured HLEC SRA01/04 cells were treated with TGF-β2,conbercept,or both,and the changes in cell proliferation,apoptosis,and migration were observed using MTT assay,flow cytometry,scratch assay,and Transwell assay.Western blotting and qRT-PCR were used to detect the changes in the expression of EMT-related epithelial cell markers(E-Cadherin,α-SMA,and Snail),extracellular matrix components,and genes related to the TGF-β/Smad signaling pathway.Results Conbercept significantly reduced TGF-β2-induced EMT of SRA01/04 cells,decreased the expression levels of mesenchymal and extracellular matrix markers α-SMA,Snail,collagen I,collagen IV,and FN1,and upregulated the protein and mRNA expressions of E-cadherin(P<0.05).Transwell assay showed significantly lower cell migration ability in TGF-β2+conbercept group than in TGF-β2 group(P<0.05).Conbercept also inhibited the increase in Smad2/3 phosphorylation levels in HLEC-SRA01/04 cells with TGF-β2-induced EMT(P<0.01).Conclusion Conbercept inhibits TGF-β2 induced EMT by downregulating the expression of pSmad2/3 in TGF-β/Smad signaling pathway,indicating a potential therapeutic strategy against visual loss induced by posterior capsule opacification.
