New therapeutic strategies against leishmaniasis are desirable, since the treatment against disease presents problems, such as the toxicity, high cost and/or parasite resistance. As consequence, new antileishmanial compounds are necessary to be identified, as presenting high activity against Leishmania, but low toxicity in mammalian hosts. In the present study, a Leishmania proteome mining strategy was developed, in order to select new drug targets with low homology to human proteins, but that are considered relevant for the parasite' survival.

Major depressive disorders impact approximately 17% of the population worldwide, whose high morbidity and considerable adversity have resulted in enormous social and economic burden. In addition, clinically depressed patients often show reduced volume of olfactory bulb (OB) and decreased olfactory sensitivity. Although mounting evidence conveyed that the gut microbiota may implicate the pathophysiology of major depressive disorder (MDD) via the microbe-gut-brain axis, knowledge about its distinctive molecular mechanism is rudimentary.

Metabolite-protein interactions define the output of metabolic pathways and regulate many cellular processes. Although diseases are often characterized by distortions in metabolic processes, efficient means to discover and study such interactions directly in cells have been lacking. A stringent implementation of proteome-wide Cellular Thermal Shift Assay (CETSA) was developed and applied to key cellular nucleotides, where previously experimentally confirmed protein-nucleotide interactions were well recaptured.

The mechanisms that underpin the formation, growth and composition of otoliths, the biomineralized stones in the inner ear of fish, are largely unknown, as only a few fish inner ear proteins have been reported. Using a partial transcriptome for the inner ear of black bream (Acanthopagrus butcheri), in conjunction with proteomic data, we discovered hundreds of previously unknown proteins in the otolith. This allowed us to develop hypotheses to explain the mechanisms of inorganic material supply and daily formation of growth bands. Read More

Background: Large-scale computational prediction of protein structures represents a cost-effective alternative to empirical structure determination with particular promise for non-model organisms and neglected pathogens. Conventional sequence-based tools are insufficient to annotate the genomes of such divergent biological systems. Conversely, protein structure tolerates substantial variation in primary amino acid sequence, and is thus a robust indicator of biochemical function. Read More

The success of clinical proteomics, per definition, is ultimately defined by the clinical implementation of proteomics findings. Extensive research activity in the field, targeting especially biomarker discovery, has been conducted the past decades, with several studies suggesting a benefit from proteome based application in patient management. This viewpoint article discusses the current status in clinical proteomics with respect to implementation, (as evidenced by use of protein findings in drug labeling and patient stratification), and proposes specific action points for accelerating the biomarker validation process, placing special emphasis on the importance of data and resource sharing.

A novel type of lipid droplet/lipoprotein (LD/LP) particle from Thermoplasma acidophilum has been identified recently, and based on biochemical evidences it was named Thermoplasma Quinone Droplet (TaQD). The major components of TaQDs are menaquinones, and to some extent polar lipids, and the 153 amino acid long Ta0547 vitellogenin-N domain protein. In this paper we aimed to identify TaQD proteome components with 1D-SDS-PAGE/Lc-MS/MS and cross reference them with Edman degradation. Read More

Our aim was to define seminal plasma proteome signatures of infertile patients categorized according to their seminal parameters using TMT-LC-MS/MS. To that extent, quantitative proteomic data was analyzed following two complementary strategies: (i) the conventional approach based on standard statistical analyses of relative protein quantification values; and (ii) a novel strategy focused on establishing stable-protein pairs. By conventional analyses, the abundance of some seminal plasma proteins was found to be positively correlated with sperm concentration. Read More

Despite recent clinical successes for irreversible drugs, potential toxicities mediated by unpredictable modification of off-target cysteines represents a major hurdle for expansion of covalent drug programs. Understanding the proteome-wide binding profile of covalent inhibitors can significantly accelerate their development; however, current mass spectrometry strategies typically do not provide a direct, amino acid level readout of covalent activity for complex, selective inhibitors. Here we report the development of CITe-Id, a novel chemoproteomic approach that employs covalent pharmacologic inhibitors as enrichment reagents in combination with an optimized proteomic platform to directly quantify dose-dependent binding at cysteine-thiols across the proteome.

Methylglyoxal (MG) is quantitatively the most important precursor to advanced glycation end-products (AGEs), and evidence is accumulating that it is also a causally linked to diabetes and aging related diseases. Living systems primarily reside on the glyoxalase system to detoxify MG into benign d-lactate. The flux to either glycation or detoxification, accordingly, is a key parameter for how well a system handles the ubiquitous glyoxal burden. Read More

Cystic fibrosis (CF) is a complex multi-organ disorder that is among the most common fatal genetic diseases benefiting from therapeutic interventions early in life. Newborn screening (NBS) for pre-symptomatic detection of CF currently relies on a two-stage immunoreactive trypsinogen (IRT) and cystic fibrosis transmembrane conductance regulator (CFTR) mutation panel algorithm that is sensitive, but not specific for identifying affected neonates with a low positive predictive value. For the first time, we report the discovery of a panel of CF-specific metabolites from a single 3. Read More

Bacteria of the phylum are regarded as highly efficient carbohydrate metabolizers, but most species are limited to (semi)soluble glycans. The soil species Cytophaga hutchinsonii and Sporocytophaga myxococcoides have long been known as efficient cellulose metabolizers, but neither species conforms to known cellulolytic mechanisms. Both species require contact with their substrate but do not encode cellulosomal systems of cell surface-attached enzyme complexes or the polysaccharide utilization loci found in many other species.

With protein synthesis being energetically expensive, the ribosome must balance the costs of efficiently making a protein with those of properly folding it. Emerging as a primary means of regulating this trade-off are the non-uniform rates of translation elongation that define translation kinetics. Read More
