Protein interaction partners of drosophila Unr identified by pull down of wild type and an interdomain mutant protein

ABSTRACT: To identify an RNP interactome of Unr, V5 tagged wildtype protein and a mutant containing several interdomain contacts, that shows reduced protein expression were tansfected in SL2 cells after a siRNA knoch-down of the endogenous protein levels. After pulling down the transfected protein with an antibody against the V5-tag differences interacting proteins were identified using mass spectrometry. One set was done with an RNase treatment and one without, to identify interaction partners that rely on RNA binding. The lower expression level of the mutant protein allowed us to take this as a specific background control.

Independent human mesenchymal stromal cell-derived extracellular vesicle preparations differentially attenuate symptoms in an advanced murine Graft-versus-Host-Disease model

Project description:Extracellular vesicles (EVs) harvested from conditioned media of human mesenchymal stromal cells (MSCs) suppress acute inflammation in various disease models and promote regeneration of damaged tissues. Following successful treatment of an acute steroid-refractory Graft-versus-Host disease (GvHD) patient with EVs prepared from conditioned media of human bone marrow-derived MSCs, we focus on improving the MSC-EV production for the clinical application. Independent MSC-EV preparations all produced according to a standardized procedure, reveal broad immunomodulatory differences. Only a proportion of our MSC-EV products effectively modulate immune responses in a multi-donor mixed lymphocyte reaction (mdMLR) assay. To explore the relevance of such differences, we have established an optimized mouse GvHD model. The functional testing of selected MSC-EV preparations demonstrate that MSC-EV preparations revealing immunomodulatory capabilities in the mdMLR assay also effectively suppress GvHD symptoms in this model. In contrast, MSC-EV preparations, lacking such in vitro activities, also fail to modulate GvHD symptoms in vivo. Searching for differences of the active and inactive MSC-EV preparations, we failed to identify concrete proteins or miRNAs that could serve as surrogate markers. Thus, standardized MSC-EV production strategies may not be sufficient to warrant manufacturing of MSC-EV products with reproducible qualities. Consequently, given this functional heterogeneity, every individual MSC-EV preparation considered for the clinical application should be evaluated for its therapeutic potency prior to administration to patients. Here, we qualified the mdMLR assay for such analyses.

Increased levels of the mitochondrial import factor Mia40 can prevent the aggregation of polyQ proteins in the cytosol

Project description:The formation of protein aggregates is a hallmark of neurodegenerative diseases. Observations on patient material and model systems demonstrated links between aggregate formation and declining mitochondrial functionality, but the causalities remained unclear. We used yeast as model system to analyze the relevance of mitochondrial processes for the behavior of an aggregation-prone polyQ protein derived from human huntingtin. Induction of Q97-GFP rapidly leads to insoluble cytosolic aggregates and cell death. Although these aggregates impaired mitochondrial respiration only slightly, they interfered with efficient import of mitochondrial precursor proteins. Mutants in the import component Mia40 were hypersensitive to Q97-GFP. Even more surprising, Mia40 overexpression strongly suppressed the formation of toxic Q97-GFP aggregates both in yeast and in human cells. Based on our observations, we propose that the posttranslational import into mitochondria competes with aggregation-prone cytosolic proteins for chaperones and proteasome capacity. Owing to its rate-limiting role for mitochondrial protein import, Mia40 acts as regulatory component in this competition with direct relevance for cytosolic proteostatic stability. Thus, targeting Mia40 might offer exciting therapeutic potential in the future. In this dataset we analyzed the soluble proteome of wild type and Mia40 overexpression yeast cells in response to the expression of polyQ proteins.

An automated and fast sample preparation workflow for laser microdissection guided ultrasensitive proteomics

Project description:Spatial tissue proteomics integrating whole-slide imaging, laser microdissection and ultrasensitive mass spectrometry is a powerful approach to link cellular phenotypes to functional proteome states in (patho)physiology. To be applicable to large patient cohorts and low sample input amounts, including single-cell applications, loss-minimized and streamlined end-to-end workflows are key. We here introduce an automated sample preparation protocol for laser microdissected samples utilizing the cellenONEÃ‚Â® robotic system, which has the capacity to process 192 samples in three hours. Following laser microdissection collection directly into the proteoCHIP LF 48 or EVO 96 chip, our optimized protocol facilitates lysis, formalin de-crosslinking and tryptic digest of low-input archival tissue samples. The seamless integration with the Evosep ONE LC system by centrifugation allows Ã¢â‚¬Ëœon-the-flyÃ¢â‚¬â„¢ sample clean-up, particularly pertinent for laser microdissected workflows. We validate our method in human tonsil archival tissue, where we profile proteomes of spatially-defined B-cell, T-cell and epithelial microregions of 4,000 Ã‚Âµm2 to a depth of ~2,000 proteins and with high cell type specificity. We finally provide detailed equipment templates and experimental guidelines for broad accessibility.

Proteomic anlaysis of Fabry iPSC derived cardiomyocytes treated with GLA modRNA

Project description:Recent studies in non-human model systems have shown therapeutic potential of modified mRNA (modRNA) treatments for lysosomal storage diseases. Here, we assessed the efficacy of a modRNA treatment to restore the expression of the ÃŽÂ±-galactosidase (GLA) gene in a human cardiac model generated from induced-pluripotent stem cell-derived from two patients with Fabry disease. In line with the clinical phenotype, cardiomyocytes from Fabry patientÃ¢â‚¬â„¢s induced pluripotent stem cells show accumulation of the glycosphinolipid Globotriaosylceramide (GB3), which is an ÃŽÂ±-galactosidase substrate. Further, the patient-specific cardiomyocytes have significant upregulation of lysosomal associated proteins. Upon modRNA treatment, a subset of lysosomal proteins were partially restored to wildtype levels, implying the rescue of the molecular phenotype associated with the Fabry genotype. Importantly, a significant reduction of GB3 levels was observed in GLA modRNA treated cardiomyocytes demonstrating that ÃŽÂ±-galactosidase enzymatic activity was restored. Together, our results validate the utility of patient IPSC-derived cardiomyocytes as a model to study disease processes in Fabry disease and the therapeutic potential of GLA modRNA treatment to reduce GB3 accumulation in the heart.

Plasma Glycomic Markers of Accelerated Biological Aging During Chronic HIV Infection

Project description:People with HIV (PWH) experience an increased vulnerability to premature aging and inflammation-associated comorbidities, even when HIV replication is suppressed by antiretroviral therapy (ART). However, the factors that contribute to or are associated with this vulnerability remain uncertain. In the general population, alterations in the glycomes of circulating IgGs trigger inflammation and precede the onset of aging-associated diseases. Here, we investigate the IgG glycomes of cross-sectional and longitudinal samples from 1,216 women and men, both living with virally suppressed HIV and those without HIV. Our glycan-based machine learning models indicate that living with chronic HIV significantly accelerates the accumulation of pro-aging associated glycomic alterations. Consistently, PWH exhibit heightened expression of senescence associated glycan-degrading enzymes compared to their controls. These glycomic alterations correlate with elevated markers of inflammatory aging and the severity of comorbidities, potentially preceding the development of such comorbidities. Mechanistically, HIV-specific antibodies glycoengineered with these alterations exhibit reduced anti-HIV IgG-mediated innate immune functions. These findings hold significant potential for the development of glycomic based biomarkers and tools to identify and prevent premature aging and comorbidities in people living with chronic viral infections.

Neonatal rat cardiomyocyte RBPome

Project description:Mutations or decreased expression of RNA-binding proteins (mRBPs) can lead to cardiomyopathies in humans. Here we defined RBPs in healthy and diseased primary cardiomyocytes at a system-wide level by RNA Interactome Capture. This identified 67 novel cardiomyocyte specific RBPs including several contractile proteins. Furthermore, we evaluated dynamic binding capacities of RBPs during pathologyical cardiac hypertrophy and identified Cytoplasmic polyadenylation element binding protein 4 (Cpeb4) as a dynamic RBP, regulating cardiac growth both in vitro and in vivo.
