STALLION SPERM PROTEINS AFTER CRYOPRESERVATION

ABSTRACT: Using a split sample design 30 ejaculates from 10 different stallions were analyzed as fresh spermatozoa, and another aliquot from the same ejaculate was analyzed as a frozen thawed sample. The proteome was studied under both conditions using UHPLC/MS/MS and bioinformatic analysis conducted to identify discriminant variables between both conditions.

Journal of proteome research 20210303 5

Although cryopreservation is widely used in animal breeding, the technique is still suboptimal. The population of spermatozoa surviving the procedure experiences changes attributed to alteration in their redox regulation. In order to expand our knowledge regarding this particular aspect, the proteome in fresh and frozen thawed aliquots of equine spermatozoa was studied to identify the proteins most severely affected by the procedure. If alteration of redox regulation is a major factor explaining ...[more]

Multifaceted Mass Spectrometric Investigation of Neuropeptide Changes in Atlantic Blue Crab, Callinectes sapidus, in Response to Low pH Stress

Project description:The decrease of pH level in the water affects animals living in aquatic habitat, such as crustaceans. The molecular mechanisms enabling these animals to survive this environmental stress remain unknown. To understand the modulatory function of neuropeptides in crustaceans when encountering drops in pH level, we developed and implemented a multifaceted mass spectrometric platform to investigate the global neuropeptide changes in response to water acidification in the Atlantic blue crab, Callinectes sapidus. Neural tissues were collected at different incubation periods to monitor dynamic changes of neuropeptides under different stress conditions occurring in the animal. Neuropeptide families were found to exhibit distinct expression patterns in different tissues and even each isoform had its specific response to the stress. Circulating fluid in the crabs (hemolymph) was also analyzed after 2-hour exposure to acidification condition, and together with results from tissue analysis, enabled the discovery of neuropeptides participating in the stress accommodation process as putative hormones. Two novel peptide sequences were detected in the hemolymph that appeared to be involved in the stress-related regulation in the crabs.

Comparative proteomic analysis and bioluminescent reporter gene assays to investigate effects of simulated microgravity on Caco-2 cells

Project description:Microgravity is one of the most important features in spaceflight. Previous evidence has shown that significant changes to the musculoskeletal and immune systems occurred under microgravity. The present study was undertaken to explore the change in protein abundance in human colon colorectal cells that were incubated for 48 or 72 h either in normal conditions and µG simulated conditions. The comparative proteomic method based on the 18O labeling technique was applied to investigate the up-regulated proteins and down-regulated proteins in SH-SY5Y under simulated microgravity.

A Universal 384-Well Proteomic Sample Preparation Platform for High-Throughput Screening and Biomarker Discovery

Project description:Major advances have been made to develop an automated universal 384-well plate sample preparation platform with high reproducibility and adaptability for extraction of proteins from cells within a culture plate. An in-solution digest strategy is employed to generate peptides from the extracted proteins for LC-MS analysis in the 384-well plate. Method evaluation utilized HeLa cells cultured in the 384-well plate ranging from 500 – 10,000 cells. Digestion efficiency was excellent in comparison to the commercial digest peptides standard with minimal sample loss while improving sample preparation throughput by 20 – 40 fold. Analysis of six human cell types, which included two primary cell samples identified and quantified approximately 4,000 proteins for each sample in a single LC-MS/MS injection with as little as 100 – 10,000 cells depending on cell type demonstrating universality of the platform. Implementation of the comprehensive 384-well format protocol for processing cells to clean digested peptides enables large-scale biomarker validation and compound screening through proteomic analysis.

Glucose-dependent insulinotropic polypeptide effects in type 1 diabetes

Project description:Glucose-dependent insulinotropic polypeptide (GIP) has been proposed to exert insulin-independent effects on lipid and bone metabolism. We investigated the effect of a 6-day s.c. GIP infusion on circulating lipids, white adipose tissue (WAT), brown adipose tissue (BAT), hepatic fat content, and inflammatory markers in patients with type 1 diabetes. In a randomized, placebo-controlled, double-blind, crossover study, 20 men with type 1 diabetes underwent a 6-day continuous s.c. infusion with GIP (6 pmol/kg/min) and placebo (saline), with an interposed seven-day washout period. Each intervention period involved three study days: Day 0 (baseline measurements, a baseline abdominal adipose tissue biopsy and blood sampling), Day 1 (fasting blood sample after 24 hours infusion), and Day 6 (fasting blood sample, an abdominal adipose tissue biopsy).

Methyl ketone production by Pseudomonas putida is enhanced by plant-derived amino acids

Project description:Methyl ketone production by P. putida with A. thaliana and switchgrass hydrolysates obtained by dilute acid pretreatment led to the identification of plant-derived amino acids, rather than mono-aromatics, as key stimulative components of these hydrolysates. Shotgun proteomics indicated that the amino acids had a specific inductive effect on proteins involved in fatty acid biosynthesis, leading to a 9-fold increase in methyl ketone titer when amending glucose-containing minimal medium with a defined set of amino acids.

Deciphering Black Extrinsic Tooth Stains composition in Children using metaproteomics

Project description:The present study focuses on the use of a metaproteomic approach to analyse Black Extrinsic Tooth Stains, a specific type of pigmented extrinsic substance, in a cohort of 96 Children. Metaproteomics is a powerful emerging technology that successfully enabled human protein and bacterial identification of this specific dental biofilm using mass spectrometry. 1600 bacterial proteins were identified in black stains (BS) samples and 2058 proteins in dental plaque (DP) samples whereas 607 and 582 human proteins identified in (BS and DP, respectively). 132 genera bacteria in black stains and dental plaque were identified using phylopeptidomic analysis, showing prevalence of Rothia, Kingella, Nesseria and Pseudopropionibatcterium in black stains samples. We additionally confirmed the metaproteomic approach by performing 16S rRNA. In this work, we showed an interesting diversity of the microbiota and proteome including significant difference between Black stain and dental plaque samples.

Mass spectrometry-based analysis of kindlin phosphorylation, ubiquitination and interactome

Project description:Kindlin is an essential activator of integrins and thus indispensable in cell to extracellular matrix (ECM) adhesion. Kindlin abundance and functions are tightly regulated by multiple mechanisms including post-translational modifications (PTMs). Despite the critical roles of kindlin during embryonic development and pathogenesis, the knowledge of kindlin’s PTMs and interactome is far from complete. Here we analyze the phosphorylation, ubiquitination and interacting partners of kindlin in flat, firmly adherent interphase cells and round, weakly attached mitotic cells by immunoprecipitation-based mass spectrometry (IP-MS). The analysis generated potential phosphorylation and ubiquitination sites as well as interactors of kindlin and paved the way to investigate PTMs and binding partners of kindlin.

The global response of Pseudomonas putida to a complex lignolysate

Project description:In this work, we developed processes using ionic liquids to obtain size-defined soluble aromatic-rich streams from sorghum biomass to assess their biocompatibility with P. putida. Growth was unexpectedly higher than that observed on a main aromatic compound. Subsequently, proteomics and metabolomics analysis revealed that BCD liquor contains additional carbon sources except aromatics. Our comparative proteomic analysis first revealed significant up-regulation of a diverse set of proteins in P. putida grown in the complex lignolysate to understand their function and regulation.
