Abiotic stress-induced chloroplast proteome remodelling: a mechanistic overview.

The chloroplast houses photosynthesis in all green plants, and is therefore of fundamental importance to the viability and productivity of plants, ecosystems, and agriculture. Chloroplasts are, however, extremely vulnerable to environmental stress, on account of the inherent volatility of oxygenic photosynthesis. To counteract this sensitivity, sophisticated systems of chloroplast stress acclimation have evolved, and many of these involve broad proteome changes. Here, we provide an overview of the interlock...

Thermal proteome profiling in bacteria: probing protein state .

Increasing antibiotic resistance urges for new technologies for studying microbes and antimicrobial mechanism of action. We adapted thermal proteome profiling (TPP) to probe the thermostability of proteins had a more thermostable proteome than human cells, with protein thermostability depending on subcellular location-forming a high-to-low gradient from the cell surface to the cytoplasm. While subunits of protein complexes residing in one compartment melted similarly, protein complexes spanning compartmen...


Application of targeted mass spectrometry in bottom-up proteomics for systems biology research.

The enormous diversity of proteoforms produces tremendous complexity within cellular proteomes, facilitates intricate networks of molecular interactions, and constitutes a formidable analytical challenge for biomedical researchers. Currently, quantitative whole-proteome profiling often relies on non-targeted liquid chromatography-mass spectrometry (LC-MS), which samples proteoforms broadly, but can suffer from lower accuracy, sensitivity, and reproducibility compared with targeted LC-MS. Recent advances in ...

Comparison of the Rat and Human Dorsal Root Ganglion Proteome.

Dorsal root ganglion (DRG) are a key tissue in the nervous system that have a role in neurological disease, particularly pain. Despite the importance of this tissue, the proteome of DRG is poorly understood, and it is unknown whether the proteome varies between organisms or different DRG along the spine. Therefore, we profiled the proteome of human and rat DRG. We identified 5,245 proteins in human DRG and 4959 proteins in rat DRG. Across species the proteome is largely conserved with some notable differenc...

Proteomic comparison of selective breeding and growth hormone transgenesis in fish: Unique pathways to enhanced growth.

In fish used for food production and scientific research, fast growth can be achieved via selective breeding or induced instantaneously via growth hormone (GH) transgenesis (GHT). The proteomic basis for these distinct routes towards a similar higher phenotype remains uncharacterized, as are associated implications for health parameters. We addressed this knowledge gap using skeletal muscle proteomics in coho salmon (Oncorhynchus kisutch), hypothesising that i) selective breeding and GHT are underpinned by ...

An update of the functional mitochondrial human proteome network.

Due to the pivotal role of mitochondrial alterations in several diseases, the Human Proteome Organization (HUPO) has promoted in recent years an initiative to characterize the mitochondrial human proteome, the mitochondrial human proteome project (mt-HPP). Here, we generated an updated version of the functional mitochondrial human proteome network, made by nodes (mitochondrial proteins) and edges (gold binary interactions), using data retrieved from neXtProt, the reference database for HPP metrics. The prin...

A Host Proteome Atlas of Streptococcus pyogenes Infection.

Multiplex quantitative proteomics analysis of mice infected with Group A Streptococcus reveals organ-specific biomarkers of infection.

Analysis of PNGase F-resistant N-glycopeptides using SugarQb for Proteome Discoverer 2.1 reveals cryptic substrate specificities.

SugarQb (www.imba.oeaw.ac.at/sugarqb) is a freely available collection of computational tools for the automated identification of intact glycopeptides from high-resolution HCD MS/MS data-sets in the Proteome Discoverer environment. We report the migration of SugarQb to the latest and free version of Proteome Discoverer 2.1, and apply it to the analysis of PNGase F-resistant N-glycopeptides from mouse embryonic stem cells. The analysis of intact glycopeptides highlights unexpected technical limitations to PN...

Assembling the Community-Scale Discoverable Human Proteome.

The increasing throughput and sharing of proteomics mass spectrometry data have now yielded over one-third of a million public mass spectrometry runs. However, these discoveries are not continuously aggregated in an open and error-controlled manner, which limits their utility. To facilitate the reusability of these data, we built the MassIVE Knowledge Base (MassIVE-KB), a community-wide, continuously updating knowledge base that aggregates proteomics mass spectrometry discoveries into an open reusable forma...

Extending single molecule imaging to proteome analysis by quantitation of fluorescent labeling homogeneity in complex protein samples.

Fluorescence-based electrophoresis has been widely used for proteome analysis, in which every protein species in cells are labeled with a fluorescent dye, separated by electric migration and are quantified using fluorescence detection. The ultimate limit of sensitivity for this approach could be reached by single-molecule fluorescence imaging and counting individual proteins, requiring exhaustive fluorescent labeling of proteins across molecular populations and species. However, it remains unclear how homog...

Proteome-based systems biology in chronic pain.

Chronic pain represents a major medical challenge in the 21 century. Enormous efforts have been invested towards deciphering the complexity of chronic pain from different angles (molecular, physiological, psychosocial, and behavioral) in both preclinical and clinical settings. While progress has been made, our understanding of the underlying mechanisms of chronic pain remains insufficient. Consequently, chronic pain treatment is often inadequate. It lacks efficacy in most patients and is associated with det...

Rapid remodeling of the host epithelial cell proteome by the listeriolysin O pore-forming toxin.

Bacterial pathogens use various strategies to interfere with host cell functions. Among these strategies, bacteria modulate host gene transcription, thereby modifying the set of proteins synthetized by the infected cell. Bacteria can also target pre-existing host proteins and modulate their post-translational modifications or trigger their degradation. Analysis of protein levels variations in host cells during infection allows to integrate both transcriptional and post-transcriptional regulations induced by...

Myeloperoxidase mediated HDL oxidation and HDL proteome changes do not contribute to dysfunctional HDL in Chinese subjects with coronary artery disease.

High density lipoprotein (HDL) cholesterol levels and cholesterol efflux capacity (CEC) are inversely correlated with coronary artery disease (CAD) risk. Myeloperoxidase (MPO) derived oxidants and HDL proteome changes are implicated in HDL dysfunction in subjects with CAD in the United States; however, the effect of MPO on HDL function and HDL proteome in ethnic Chinese population is unknown. We recruited four matched ethnic Chinese groups (20 patients each): subjects with 1) low HDL levels (HDL levels in m...

Orthologous proteins of experimental de- and remyelination are differentially regulated in the CSF proteome of multiple sclerosis subtypes.

Here, we applied a multi-omics approach (i) to examine molecular pathways related to de- and remyelination in multiple sclerosis (MS) lesions; and (ii) to translate these findings to the CSF proteome in order to identify molecules that are differentially expressed among MS subtypes.

Flexible and fast mapping of peptides to a proteome with ProteoMapper.

Bottom-up proteomics relies on the proteolytic or chemical cleavage of proteins into peptides, the identification of those peptides via mass spectrometry, and the mapping of the identified peptides back to the reference proteome to infer which possible proteins are identified. Reliable mapping of peptides to proteins still poses substantial challenges when considering similar proteins, protein families, splice isoforms, sequence variation, and possible residue mass modifications, combined with an imperfect ...

Curcumin exerts its antitumor effects in a context dependent fashion.

Proteome profiling profoundly contributes to the understanding of cell response mechanisms to drug actions. Such knowledge may become a key to improve personalized medicine. In the present study, the effects of the natural remedy curcumin on breast cancer model systems were investigated. MCF-7, ZR-75-1 and TGF-β1 pretreated fibroblasts, mimicking cancer-associated fibroblasts (CAFs), were treated independently as well as in tumor cell/CAF co-cultures. Remarkably, co-culturing with CAF-like cells (CLCs) ind...

Inventory of proteoforms as a current challenge of proteomics: Some technical aspects.

The main intricacy in the human proteome is that it is tremendously complex and composed from diverse and heterogeneous gene products. These products are called protein species or proteoforms and are the smallest units of the proteome. In pursuit of the comprehensive profiling of the human proteome, significant advances in the technology of so called "Top-Down" mass spectrometry based proteomics, have been made. However, the scale of performance of this approach is still far behind the "Bottom-Up", peptide-...

Identification of viral domains integrated into Arabidopsis proteome.

Horizontal gene transfer (HGT) contributes to the genome evolution of living organisms. In particular, several recent studies provide convincing data on the integration of viral sequences into diverse organisms. Here, we identified 101 viral domains integrated into the model plant Arabidopsis proteome. Functional analysis based on gene ontology (GO) terms indicates that viral domains in the Arabidopsis proteome were involved in various stress responses with binding functions. Protein interaction networks su...

To evaluate changes in the high-density lipoprotein (HDL) proteome and HDL function in active rheumatoid arthritis (RA) patients initiating therapy with abatacept or adalimumab in the Abatacept Versus Adalimumab Comparison in Biologic-Naïve RA Subjects with Background Methotrexate (AMPLE) study.

Proteome Profiling of Sertoli Cells Using a GeLC-MS/MS Strategy.

Proteomics is a technology that allows to decipher the molecular networks involved in the regulation of biological processes such as spermatogenesis. Sertoli cells (SCs) are key players in the paracrine control of this process. Envisioning to increase the knowledge on the molecular networks harbored in SCs, we propose a methodology based on GeLC-MS/MS for the characterization of these cells' proteome. Proteins are separated by SDS-PAGE hyphenated to HPLC and identified by mass spectrometry. The integration ...

Proteome Imbalance of Mitochondrial Electron Transport Chain in Brown Adipocytes Leads to Metabolic Benefits.

Brown adipose tissue (BAT) thermogenesis is critical for thermoregulation and contributes to total energy expenditure. However, whether BAT has non-thermogenic functions is largely unknown. Here, we describe that BAT-specific liver kinase b1 knockout (Lkb1) mice exhibited impaired BAT mitochondrial respiration and thermogenesis but reduced adiposity and liver triglyceride accumulation under high-fat-diet feeding at room temperature. Importantly, these metabolic benefits were also present in Lkb1mice at ther...

Fasting and refeeding induces changes in the mouse hepatic lipid droplet proteome.

During fasting, the liver increases lipid storage as a mean to reserve and provide energy for vital cellular functions. After re-feeding, hepatocytes rapidly decrease the amount of triacylglycerol that is stored in lipid droplets (LDs), visible as the size of hepatic LDs significantly decreases after re-feeding. Little is known about the changes in the liver LD proteome that occur during the fasting/re-feeding transition. This study aimed to investigate the hepatic LD proteome in fasted and re-fed condition...
