Bottom-up mass spectrometry-based proteomics utilizes proteolytic enzymes with well characterized specificities to generate peptides amenable for identification by high-throughput tandem mass spectrometry. Trypsin, which cuts specifically after the basic residues lysine and arginine, is the predominant enzyme used for proteome digestion, although proteases with alternative specificities are required to detect sequences that are not accessible after tryptic digest. Here, we show that the human cy ...[more]

On-tissue spatially-resolved glycoproteomics guided by N-glycan imaging reveal global dysregulation of canine glioma glycoproteomic landscape

Project description:Here we present an approach to identify N-linked glycoproteins and deduce their spatial localization using a combination of MALDI N-glycan MSI and spatially-resolved glycoproteomics. We subjected glioma biopsies to on-tissue PNGaseF digestion and MALDI-MSI and found that the glycan HexNAc4-Hex5-NeuAc2 was predominantly expressed in necrotic regions of high-grade canine gliomas. To determine the underlying sialo-glycoprotein, various regions in adjacent tissue sections were subjected to microdigestion and manual glycoproteomic analysis. Results identified haptoglobin as the protein associated with HexNAc4-Hex5-NeuAc2, making our study the first report that directly links glycan imaging with intact glycopeptide identification. In total, our spatially-resolved glycoproteomics technique identified over 400 N-, O-, and S- glycopeptides from over 30 proteins, demonstrating the diverse array of glycosylation present on the tissue slides and the sensitivity of our technique. Ultimately, this proof-of-principle work demonstrates that spatially-resolved glycoproteomics greatly complement MALDI-MSI in understanding dysregulated glycosylation.

Salvage pathway maintains functional respiratory complex I

Project description:Regulation of the turnover of complex I (CI), the largest mitochondrial respiratory chain complex remains enigmatic, despite huge advancement in understanding its structure and the assembly steps in recent years. Although some studies indicated that CI might be remodelled in response to various stimuli, the mechanism mediating these putative changes is unknown. Here, we report that the NADH-oxidising N-module which sits on the tip of the CI peripheral arm is turned over at a higher rate and largely independently of the rest of the complex. The N-module turnover is mediated by mitochondrial matrix protease ClpXP, which selectively removes and degrades damaged core subunits. The observed mechanism seems to be a safeguard against accumulation of dysfunctional CI arising from inactivation of the N-module subunits due to attrition caused by extensive redox activity. This CI salvage pathway maintains highly functional CI and healthy mitochondria through an energetically favourable mechanism that demands much lower energetic cost than de novo synthesis and reassembly of the entire CI.

RA heat-shock

Project description:Within a GRO experiment, samples for mRNA amount (RA) were taken at 0, 4, 11, 16, 26 and 40 minutes after heat stress (from 25ºC to 37ºC). Analysis was done in filters also used for Transcription rate (TR) analysis of aliquots from the same cultures. The analysis includes 3 repeats of stress treatment of the W3030-1a strain. The same times were used for sampling in each repeat of the experiment. A single genomic DNA hybridization on every one of the filters is used for normalization between gene probes.
