- One of the biggest challenges in plasma proteomics is to reduce the dynamic range of plasma proteins to capture the expression of low-abundance proteins. Although abundant protein depletion and proximity extension assay are widely used for human samples, the application to animal species in non-clinical assessment remains limited. Here, we evaluated the Mag-Net and ENRICH-iST methods using 20 μL of plasma from both healthy and type 2 diabetes model rats. By combining with the optimized LC-MS method, Mag-Net identified more proteins than ENRICH-iST with high precision, although both methods identified over 5,000 proteins. Using integrative proteomics and analytical approaches, including extracellular vesicle (EV) database comparison, Gene Ontology (GO) analysis, Simple Western, nanoparticle tracking analysis (NTA), and contamination assessments, we demonstrated in rat plasma that Mag-Net preferentially enriches EV proteins, whereas ENRICH-iST more evenly captures low-abundance proteins, including EV proteins. Regardless of the protein enrichment method employed, more than half of the tissue-specific proteins were classified as being specific to either the liver or the brain tissues. Whereas, several liver-specific proteins involved in protein-protein interactions (PPI), including Proz/Serpina10 and Ambp/Itih1/Itih2, were identified as exhibiting over a ten-fold increase in mean quantification values in the Mag-Net method compared to ENRICH-iST, suggesting enhanced enrichment of PPI network. Ingenuity Pathway Analysis (IPA) identified 219 downregulated and 80 upregulated proteins in the Mag-Net method dataset (fold change ≥ 1.5, p ≤ 0.05), and 68 downregulated and 43 upregulated proteins in the ENRICH-iST method dataset (fold change ≥ 1.5, p ≤ 0.2). Some significantly downregulated pathways, such as elastic fiber formation, were uniquely identified by the Mag-Net method. This approach was shown to be a powerful tool for investigating deregulated proteins and pathways. Potential applications include biomarker discovery and the assessment of drug efficacy and safety during development. - Source: PubMed

Takahashi RyoProdinger FlorianMatsui Akiko - Children with complicated severe malnutrition (CSM) face high mortality after hospital discharge, yet the underlying mechanisms remain poorly understood. While early post-discharge mortality (< 2 months) has been linked to a sepsis-like inflammatory profile measured at discharge, it is unclear whether this relationship persists (later mortality; 2-6 months post-discharge). This study investigated whether immune, inflammatory, and endothelial dysfunction at 2 months post-discharge are associated with later mortality in children recovering from CSM. - Source: PubMed

Kamau BrendaMudibo Evans OWechessa CecilliaOmer ElishaGichuki Bonface MMburu David MMwalekwa LauraTimbwa MollineThitiri JohnstoneNgari Moses MBerkley James ANjunge James M - : Fabry disease (FD) is an X-linked lysosomal storage disorder caused by mutations, leading to deficient α-galactosidase A (α-Gal A) activity and progressive glycosphingolipid accumulation. While α-Gal A activity is the diagnostic gold standard, its sensitivity is reduced in late-onset or heterozygous patients. Conventional biomarkers such as lyso-Gb3 provide only limited insight into disease progression and therapeutic response. Exosomes, as stable carriers of disease-specific proteins, may offer complementary biomarkers for early detection and longitudinal monitoring. : Twenty-one pediatric FD patients with confirmed GLA mutations were enrolled. Clinical, enzymatic, renal, and cardiac parameters were assessed. Plasma-derived exosomes were characterized by transmission electron microscopy and proteomic profiling. Differentially expressed proteins were identified using mass spectrometry, analyzed using GO/KEGG enrichment, and validated using RT-PCR, ELISA, and immunofluorescence in patient samples and mice. : Male patients showed markedly reduced α-Gal A activity and elevated lyso-Gb3 compared with females. Although overt renal and cardiac dysfunction was uncommon, several patients exhibited early abnormalities such as proteinuria, an elevated LVMI, or increased cTnI levels. Proteomic analysis identified 2553 proteins, of which 188 were differentially expressed. Fibrosis- and inflammation-related proteins, including THBS1 and CFHR5, were upregulated, while protective factors such as APM1, SERPINA10, and CAB39 were downregulated. IGFBP3 was also elevated and closely linked to tissue remodeling. Enriched pathways were involved in PPAR/AMPK signaling, lipid metabolism, and complement activation. : Exosomal proteomic profiling revealed early molecular signatures of cardiorenal involvement in pediatric FD. Key proteins such as THBS1, CFHR5, IGFBP3, APM1, and CAB39 show strong potential as biomarkers for risk stratification, disease monitoring, and therapeutic evaluation. - Source: PubMed

De Moner BlancaMartinez-Sanchez JuliaEscribano-Serrat SilviaRamos AlexMoreno-Castaño Ana BelénArellano-Rodrigo EduardoEscolar GinésCarreras EnricÁlvarez-Larrán AlbertoDiaz-Ricart Maribel - Serpins, characterized by a conserved structural fold, serve diverse biological roles. Protein Z-dependent protease inhibitor (ZPI), a serpin superfamily member, acts as an endogenous anticoagulant by inhibiting clotting factors Xa (fXa) and XIa (fXIa). Beyond anticoagulation, ZPI has roles in inflammation, cancer, and immune regulation. However, its exact pathophysiological role is yet to be fully characterized. To elucidate ZPI's evolutionary trajectory and non-haemostatic roles, we conducted a comprehensive phylogenetic analysis integrating sequence, gene structure, and synteny data. We identified a lamprey-specific serpin, ZPIL_AGTL_PMA, containing both an inhibitory reactive center loop (RCL) and an angiotensin II (Ang II) motif. This finding suggests that ZPIL_AGTL_PMA represents an ancestral bifunctional serpin from which ZPI and angiotensinogen (AGT), a non-inhibitory serpin involved in blood pressure regulation, evolved by sub-functionalization in jawed vertebrates. This bifunctionality within a single gene in lamprey likely reflects an ancestral vertebrate trait. Gene cluster analyses showed serpinA10 (ZPI) as possibly the earliest member, with other Clade A serpins arising via subsequent duplication. The chromosomal location of this gene cluster is conserved in most vertebrates, except Carnivores and Suidea. Sequence analysis indicated potential non-inhibitory ZPI variants in certain species with atypical non-serine residues at the P1' position within its RCL, a critical determinant of inhibitory serpin activity. The close evolutionary relationship between ZPI and AGT further suggests mechanistic interplay between coagulation and blood pressure regulation, highlighting shared regulatory pathways involving these serpins. Together, these findings expand the functional landscape of ZPI and underscore the dynamic evolution of serpin-mediated physiological processes. - Source: PubMed
