- Biological mechanisms underlying heterogeneous antipsychotic response in schizophrenia remain incompletely understood. In this exploratory cross-sectional study, we applied deep data-independent acquisition LC-MS/MS plasma proteomics to 56 adults initially enrolled (14 per group), including healthy controls and patients meeting TRRIP criteria for treatment-sensitive (TSS), treatment-resistant (TRS), and ultra-treatment-resistant schizophrenia (UTRS). Following proteomic quality control and exclusion of outliers, 52 individuals comprised the final analytical cohort. Proteomic data were analyzed using a layered strategy integrating covariate adjustment, variance partitioning, mediation analysis, monotonicity filtering, LASSO stability assessment, and redundancy reduction. More than 1400 plasma proteins were quantified; 450 differed across groups before adjustment, and 310 reviewed proteins remained significant after covariate modeling. A sensitivity-associated profile distinguishing TSS from controls (CRP, CCDC62, FBXW7, GULP1, CALD1, COPS6) was consistent with lower inflammatory tone and relative preservation of proteostatic and cytoskeletal regulation. In contrast, a resistance-associated profile separating TRS/UTRS from TSS (SHROOM1, MYH7, ABR, EZR, SERPINF2) converged on cytoskeletal organization, actin-membrane dynamics, and extracellular regulatory processes. Directionally concordant but quantitatively amplified changes were observed in UTRS relative to TRS, although multivariate separation between resistant subgroups was limited after full covariate adjustment. Several proteins enriched in resistant groups corresponded to intracellular or nuclear factors rarely detected in plasma and require cautious interpretation. Overall, these findings are compatible with a progression-like molecular pattern in which treatment sensitivity and resistance may reflect shifts in cellular adaptability and structural regulation. Replication in larger and longitudinal cohorts is required. - Source: PubMed

In this study, we used quantitative 4D proteomics, integrating ion mass-to-charge ratio (m/z), retention time, ion intensity, and ion mobility, to profile renal tissues from a novel rat CI-AKI model based on renal venous congestion and contrast exposure, with sham-operated rats as controls. Differentially expressed proteins were identified and analyzed using pathway enrichment and protein-protein interaction (PPI) network approaches, followed by experimental validation. Using nominal screening criteria (|log2FC| ≥ 1.5 and < 0.05), we identified 180 candidate differentially expressed proteins, including 92 upregulated and 88 downregulated proteins. Pathway-level analyses showed coordinated upregulation of complement-related proteins, including C3/C5 convertase-related components and terminal pathway proteins, such as C9, together with a C4 isoform annotated as C4a in the reference database. Coagulation and fibrinolysis pathways were also markedly altered, including fibrinogen chains (FGA, FGB, FGG), PLAU, SERPINA1, and SERPINF2. In contrast, proteins associated with AMPK and MAPK signaling (including HNF4α, PRKAA2, PRKAB1, and MAP2K3) were reduced. These pathway-level changes were supported by RT-qPCR and immunohistochemical analyses. Collectively, our findings support a multidimensional injury network in rat CI-AKI involving complement activation, coagulation-fibrinolysis dysregulation, and impaired metabolic/stress-response signaling, and provide a proteomic resource for future mechanistic and translational studies. - Source: PubMed

Yang QiangSun LimingZhang ZhijianYan ZhixinZhang JianHu JiachangDing Xiaoqiang - Low-dose aspirin (LDA) reduces preeclampsia (PE) risk by up to 40%, yet its molecular effects on chorion trophoblast cells (CTCs) a fetal membrane lineage at the feto-maternal interface remain obscure. CTCs form a structural and immunoregulatory barrier whose dysfunction drives inflammation-associated membrane pathology in PE. Extracellular vesicles (EVs) released by CTCs may encode cellular stress and adaptation states, offering a molecular window into aspirin's timing-dependent effects on PE risk modification. - Source: PubMed

Beyond biological complexity, this low translational yield reflects the lack of systematic criteria for prioritizing biomarkers during the discovery stage. In particular, tumor-derived signals identified in tissue often fail to persist in clinically accessible biofluids, as cross-compartment signal behavior is rarely evaluated explicitly. - Source: PubMed

Kotawong KanawutRoytrakul SittirukPhaonakrop NarumonNa-Bangchang KesaraChaijaroenkul Wanna - Sex differences, in terms of prevalence, symptoms and disease progression, are established in the etiology of complex neurodegenerative diseases, including amyotrophic lateral sclerosis, Parkinson's disease and Alzheimer's disease, but the underlying biology driving these differences remains poorly understood. There is emerging evidence, through genetic and functional analyses, affirming the role of the immune system in such diseases, but a thorough assessment of sex differences linking the immune system and neurodegenerative diseases is understudied. Here, we applied a robust causal inference approach, two-sample Mendelian randomization, to evaluate the causal effect of immune-related protein levels on three neurodegenerative diseases with large-scale sex-stratified genome-wide association data available: amyotrophic lateral sclerosis (females = 10,895 cases, 57,062 controls; males = 15,547 cases, 50,145 controls), Parkinson's disease (females = 7,947 cases, 90,662 controls; males = 13,020 cases, 89,660 controls) and Alzheimer's disease (females = 18,822 cases, 281,415 controls; males = 17,293 cases, 213,339 controls). As exposures, we focused on 932 immune system-related proteins with significant protein cis-quantitative trait loci (FDR cutoff < 0.01) from a large sex-combined plasma protein dataset (N = 33,477), for which corresponding genes were included in the Immunology Database and Analysis Portal gene list. We tested for a causal relationship between genetically predicted levels of each of these proteins and each neurodegenerative disease in sex-stratified and sex-combined data, followed by colocalization and estimation of sex-differential effects. We additionally performed exploratory analyses using sex-combined CSF protein cis-quantitative trait loci (N = 971) as exposures. We observed evidence for a sex-differential causal relationship between FCGR2A and Parkinson's disease, and between CD2AP, MAMDC2, PCDH17 or CSF3 and Alzheimer's disease. We validated significant results using two independent protein cis-quantitative trait loci datasets for those plasma proteins available. After performing sensitivity analyses, we validated the potential causal relationships of OMG on Parkinson's disease and of GRN, SERPINF2 and TREM2 on Alzheimer's disease. Mendelian randomization with CSF protein cis-quantitative trait loci showed a potential causal effect of ADGRE2, GPNMB and COLEC11 on Parkinson's disease and of CD33 on Alzheimer's disease, without evidence of sex-differential effects. Finally, we substantiated our findings of protein-disease pairs using triangulation, specifically reporting independent supporting evidence from the literature and drug-related databases. Overall, our results point to potential causal effects of genetically predicted levels of immune system-related plasma and CSF proteins in Alzheimer's disease and Parkinson's disease, some of which may be considered as potential candidates for drug development. - Source: PubMed
