Mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene cause (CF), a multiorgan disease that is characterized by diverse metabolic defects. However, other than specific CFTR mutations, factors influence progression and severity remain poorly understood. Aberrant metabolite levels have been reported, but whether loss itself or secondary abnormalities (infection, inflammation, malnutrition, various treatments) drive defects uncertain. Here, we implemented comprehensive arteriovenous metabolomics newborn CF pigs, results revealed as bona fide of metabolism. impaired exchange across organs, including disruption lung uptake fatty acids, yet enhancement arachidonic acid, precursor proinflammatory cytokines. also kidney reabsorption amino acids lactate abolished renal glucose homeostasis. These additional unexpected prior to manifestations reveal fundamental role for controlling Such discovery informs basic understanding CF, provides foundation future investigation, has implications developing therapies targeting only single tissue.

Key Points Integrated analysis of proteome and metabolome identifies modules associated with CKD progression kidney failure. Ephrin transmembrane proteins podocyte-expressed CRIM1 NPNT emerged as central components warrant experimental clinical investigation. Background Proteins metabolites play crucial roles in various biological functions are frequently interconnected through enzymatic or transport processes. Methods We present an integrated 4091 630 the Chronic Renal Insufficiency Cohort study ( N =1708; average follow-up for failure, 9.5 years, 537 events). were using unsupervised clustering method, we assessed associations between clusters failure Cox proportional hazards models. Analyses adjusted demographics risk factors, including eGFR urine protein–creatinine ratio. Associations identified a discovery sample (random two thirds, n =1139) then evaluated replication (one third, =569). Results 139 correlated metabolites, which represented by their principal components. Modules component loadings projected onto sample, demonstrated consistent network structure. Two modules, representing total 236 82 robustly both validation samples. Using gene set enrichment, several transmembrane-related terms overrepresented these modules. Transmembrane–ephrin receptor activity displayed largest odds (odds ratio=13.2, P value = 5.5×10 −5 ). A module containing expressed podocytes particularly strong 2.6×10 Conclusions This demonstrates that integration can identify pathophysiologic importance disease.

Protein carbamylation, a post-translational protein modification primarily driven by urea, independently associates with adverse clinical outcomes in patients CKD. Biomarkers used to quantify carbamylation burden have mainly included carbamylated albumin (C-Alb) and homocitrulline (HCit, lysine). In this study, we aimed compare the prognostic utility of these two markers order facilitate comparisons existing studies employing either marker alone, inform future studies.

Abstract Purpose Homoarginine (hArg) is an arginine metabolite that has been known for years, but its physiological role in the body remains poorly understood. For instance, it well high hArg concentrations blood are protective against several disease states, yet mechanisms behind these health benefits unclear. This review compiles what about hArg, namely synthetic pathways, different diseases and conditions, proposed of action humans experimental animals. Findings Previous work identified multiple pathways control synthesis degradation body. Furthermore, endogenous can modulate cardiovascular system, with decreased being associated complications increased mortality. Studies also suggest could serve as a diagnostic biomarker variety immune, pancreatic, renal, hepatic dysfunctions. Finally, women, rapidly increase throughout pregnancy there suggestions alterations indicate like pre‐eclampsia. Summary under‐appreciated amino acid potential wide‐ranging roles systemic health, pregnancy, pathophysiology. Although recent research focused on or associations, need more investigations into understanding mechanistic by which may operate. be aided using metabolomics, provides comprehensive approach to correlating metabolites metabolic effects. Increasing our knowledge hArg's pave way routine use both therapeutic molecule.
