Objective:This study aims to investigate sex-specific abnormalities?? in gray matter volume (GMV) in Children with autism spectrum disorder (ASD) and their associations with gene expression.Methods:T 1-weighted brain MRI data were collected at the MRI Center of the University of Electronic Science and Technology of China between 2022 and 2023 from 100 children with ASD and 90 typically developing (TD) children. Voxel-based morphometry (VBM) was used to explore GMV differences between ASD boys and TD boys, and between ASD girls and TD girls. Partial least squares regression (PLSR) was performed based on the Allen Human Brain Atlas to identify genes associated with GMV alterations, followed by enrichment analyses. Cell-type-specific expression analyses were used to examine associations across developmental stages and brain structures. Protein-protein interaction (PPI) networks were constructed to identify hub proteins. Results:Compared to TD boys, ASD boys showed increased GMV in the right superior temporal gyrus, middle temporal gyrus, inferior temporal gyrus, temporal pole, parahippocampal gyrus, fusiform gyrus, cuneus, and precuneus, as well as in the bilateral orbital part of the superior frontal gyrus and the gyrus rectus. Decreased GMV was observed in the cerebellar vermis and bilateral cerebellar hemispheres. A total of 635 genes were associated with these GMV alterations, enriched in pathways related to DNA-templated transcription, RNA metabolism and biogenesis, and ion binding. Developmental analysis indicated strong associations with the cerebellum during early, middle-to-late childhood, and adolescence, and with the cerebral cortex in early adulthood. Protein-protein interaction (PPI) network analysis highlighted NOB1, GNL3L, ESF1, TFB2M, and WDR75 as specific hub proteins. Compared to TD girls, ASD girls exhibited increased GMV in the right middle and inferior temporal gyri, temporal pole, and fusiform gyrus, and decreased GMV in the cerebellar vermis and bilateral cerebellar hemispheres. A total of 765 genes were associated, enriched in pathways related to ion channel activity, signal transduction, and regulation of membrane potential. These genes showed strong associations with the amygdala during mid-to-late fetal development, middle-to-late childhood, adolescence, and early adulthood; with the cerebellum during late infancy, early childhood, and early adulthood; with the cerebral cortex during the mid-to-late fetal development, early neonatal period, and adolescence; with the hippocampus during middle-to-late childhood and adolescence; with the striatum during adolescence and early adulthood; and with the thalamus during early-to-mid fetal development, early neonatal period, and early adulthood. PPI network analysis identified ANK3, ANK1, SCN4B, NFKB1, and PXN as specific hub proteins. Conclusion:Both ASD boys and ASD girls exhibit GMV abnormalities compared with TD controls. The specific genes associated with GMV alterations are enriched in distinct biological pathways in boys and girls. Cell-type-specific expression analyses further revealed sex-dependent differences in developmental timing and brain structural correlations, and distinct PPI networks were constructed for each group.

OBJECTIVE To explore the mechanism of action of active components of Nostoc commune in anti-triple-negative breast cancer(TNBC) by the network pharmacology method and molecular biology experiment. METHODS The active components of Nostoc commune were collected by consulting the literature and combined with the preliminary research in the laboratory, the Swiss Target Prediction database was used for target prediction, and the disease targets were obtained in the TTD, Genecards and OMIM databases. The STRING online platform was used for protein-protein interaction, and the KEGG signaling pathway and GO gene function enrichment analysis were performed using the Metascape database. Molecular docking of N-acetyltryptamine, a component of Nostoc commune, and target AKT1 by AutoDock software. Annexin V-FITC/PI double staining method was performed to analyze the apoptotic rate of cells. RT-qPCR and Western blotting were used to detect the mechanism of action of the active components of Nostoc commune on anti-TNBC. RESULTS The results of network pharmacology showed that there were 8 effective components, such as N-acetyltryptamine, Scytonemin and Nostocionone, involved 75 key targets such as signal transduction and AKT1, STAT3 and CCND1. The KEGG signaling pathway and GO gene function enrichment analysis results involved cancer-related signaling pathways, PI3K-Akt signaling pathways and MAPK signaling pathways. Molecular docking showed that N-acetyltryptamine had better affinity with AKT1. N-acetyltryptamine could not significantly promote apoptosis of breast cancer cells. Western blotting showed that N-acetyltryptamine could down-regulate the protein expressions of AKT1. The results of RT-qPCR showed that N-acetyltryptamine could effectively reduce the mRNA expression of AKT1 in cells. CONCLUSION N-acetyltryptamine may inhibit the proliferation of TNBC cells by inhibiting the AKT1 signaling pathway, thereby exerting anti-TNBC effects.

OBJECTIVE To investigate the therapeutic effect of natural phenolic compound p-hydroxybenzoic acid(HA) on adjuvant arthritis(AA) induced by the complete Freund's adjuvant(CFA), and to clarify the mechanism of HA preliminary. METHODS Apart from the normal group, all rats received 0.1 mL CFA by plantar subcutaneous injection to induce AA rats model. And rats with AA were randomized to the model group, the low-, medium-, and high-dose HA group(2.5, 5, and 10 mg·kg-1, respectively), the positive control group(indomethacine, 5 mg·kg-1). The rats in each group were orally treated with the corresponding drugs for therapeutic intervention. The volume and leg thickness of the rats in each group were recorded and an inflated articular score was obtained. Inflammation cytokine expression(TNF-α, IL-1β and IL-6) was determined by ELISA and qPCR. Radiographs and HE staining were used to observe histopathological and pathological changes in the foot. The expressions of caspase-1 and NF-κB were examined in Western blotting. RESULTS HA could significantly alleviate joint swelling in AA rat(P<0.05), inhibited the production of inflammatory factors(TNF-α, IL-1β and IL-6) from protein and mRNA levels(P<0.05), and decreased the expression levels of caspase-1 and NF-κB at protein level(P<0.05). HA alleviated ankle injury in rats by X-ray examination, and HE staining showed that HA could significantly inhibit the infiltration of inflammatory cells and the destruction of cartilage surface(P<0.05), and these results were dose-dependent. CONCLUSION HA may relieve rheumatoid arthritis by inhibiting the NF-κB/casepase-1 signaling pathway.
