Bottlenose Dolphin Plasma Proteome

ABSTRACT: This study was designed to characterize and evaluate the proteome in plasma samples collected before and after a public swim interaction involving four male (2 to 6 y) aquarium-based bottlenose dolphins (Tursiops truncatus). Blood samples were collected from the tail flukes appoximately 15 min before (n=4 samples) and 15 min after (n=4 samples) the first swim interaction of the day, which was reinforced by a regularly scheduled feeding regimen. Samples were subjected to liquid chromatography-tandem mass spectrometry (LC-MS/MS) as well as conventional clinical biochemistry analysis. Mass spectra data were used to search the NCBI database restricted to Tursiops truncatus which resulted in the identification of 196 unique proteins with a broad range of functional roles based on manual GO analysis. Differential regulation of proteins was based on log2 mean fold change (FC) and statistical probability such that the abundance of lysozyme (FC -1.2036; P<0.058) an immune-related protein and flavin reductase (FC -0.9702; P<0.004) a metabolic-related protein were highest before compared to after the swim interaction. Both proteins decreased by 58 and 52%, respectively.

Analysis of the proteome of individual equine cumulus complexes after maturation in-vitro and in-vivo

Project description:Maturation of oocytes under in-vitro conditions (IVM) results in impaired developmental competence compared to oocytes matured in-vivo. Oocytes are closely coupled to their cumulus complex (COC) with a bidirectional exchange of metabolites. Therefore, elucidation of aberrations in cumulus metabolism in-vitro is crucial for a better mimicking of physiological maturation conditions. The aim of this study was the analysis of the equine cumulus cells proteome of single cumulus complexes of metaphase II oocytes matured either under in-vivo (n=8) or in-vitro (n=7) conditions. For in-vivo COC collection mares were slaughtered 30 hours after injection and cumulus complexes from the dominant follicle were harvested for analysis. For in-vitro maturation COCs were recovered from mares out of oestrous and matured for 30 hours in-vitro. COCs were separated in cumulus complexes and oocytes, and only cumulus of successfully matured oocytes was analyzed for this study. All cumulus samples were washed, snap frozen and stored in liquid nitrogen until preparation for analysis.

The bovine cumulus proteome of cumulus oocyte complexes that successfully matured or failed to mature after maturation in-vitro and in-vivo

Project description:The oocyte forms a complex with their somatic cumulus cells within the follicle throughout the preovulatory maturation steps. Cumulus cells support their oocyte not only through mechanical protection but also with a close bidirectional exchange of metabolites. Analysis of the oocytes cumulus gives the opportunity to explore non-invasively oocytal well-being and quality. In vitro maturation (IVM) is the first rate-limiting step in in vitro embryo production. Analysis of protein expression in cumulus cells around this critical step helps to explore the impact of maturation conditions and to examine an influence on maturational competence of the oocyte. The goal of this study was the comparison of the cumulus proteome of oocytes with and without maturational competence matured under in vivo and in vitro conditions. Therefore twenty cumulus samples corresponding to single oocytes were analysed. Half of the samples were matured in vivo and the other half in vitro. For each maturation group, cumulus from oocytes matured successfully (SM; n=5) and failed to mature (FM; n=5) were analysed.

Distinct lactation-associated macrophages exist in murine mammary tissue and human milk

Project description:Macrophages are involved in immune defense, organogenesis and tissue homeostasis. They also contribute to the different phases of mammary gland remodeling during development, pregnancy and involution post-lactation. Yet, less is known about the dynamics of mammary gland macrophages in the lactation stage. Here, we describe a macrophage population present during lactation in mice. By multi-parameter flow cytometry and single-cell RNA sequencing we reveal this population as distinct from the two resident macrophage subsets present pregestationally. These lactation-induced macrophages (LiMacs) are predominantly monocyte-derived and expand by proliferation in situ concomitant with nursing. LiMacs develop independently of IL-34 but require CSF-1 signaling and are partly microbiota-dependent. Locally, they reside adjacent to the basal cells of the alveoli and extravasate into the milk. Moreover, we also found several macrophage subsets in human milk, resembling LiMacs. Collectively, these findings reveal the emergence of unique macrophages in the mammary gland and milk during lactation.

Signaling network response to alpha-particle targeted therapy with actinium-225 labeled minigastrin analogue 225Ac-PP-F11N

Project description:Alpha-particle emitters have recently been explored as valuable therapeutic radionuclides. Yet, toxicity to healthy organs and cancer radioresistance limit the efficacy of targeted alpha-particle therapy (TAT). Identification of the radiation-activated mechanisms, which drive cancer cell survival, provides opportunities to develop new points for therapeutic interference to improve the efficacy and safety of TAT. Quantitative phosphoproteomics and matching proteomics followed were employed to identify alterations in the signaling networks in response to TAT with actinium-225 labeled minigastrin analogue 225Ac-PP-F11N in A431 cells, which overexpress cholecystokinin B receptor (CCKBR).

Identification of the UT-A1 Urea Channel Interactome

Project description:The urea channel Slc14a2 (or UT-A1) mediates vasopressin-regulated urea transport across the inner medullary collecting duct (IMCD). Previously, UT-A1 was found to present in a high molecular weight complex, suggesting UT-A1 is involved in certain protein-protein interactions. The present study sought to identify the proteins that interact with UT-A1 in this complex for a better understanding of how UT-A1 is regulated. Rat IMCD suspensions were treated with or without V2 receptor agonist, dDAVP, followed by in-cell crosslinking using BSOCOES and detergent solubilization. Immunoprecipitation using Dynabeads coated with UT-A1 specific antibody successfully pulled down the UT-A1 proteins. In-gel digestion protocol was carried out to prepare samples for liquid chromatographic mass spectrometry analysis of tryptic peptides using a Velos-Orbitrap mass spectrometer. The peptides passing stringent spectral quality thresholds were quantified (label-free) to identify those with (UTA-1 antibody/preimmune IgG) >4. A total of 128 UT-A1 interacting proteins were identified. Gene Ontology analysis maps the distribution of these proteins throughout major cell compartments: endoplasmic reticulum, Golgi, endosomes, cytosol and plasma membrane. Among them are four protein kinases (Cdc42bpb, Phkb, Camk2d, Mtor) that play roles in vasopressin-regulated phosphorylation of UT-A1. Non-label quantification was also performed to determine the stoichiometry of UT-A3 with UT-A1, the result does not support an oligomeric complex formation of UT-A1/A3. In conclusion, we have provided a refined list of UT-A1 binding proteins which can be useful for further analysis of the vasopressin signaling pathway in regulation of UT-A1 in IMCD.

Tear proteome revealed association of S100A family proteins and mesothelin with thrombosis in elderly patients with retinal vein occlusion

Project description:Tear samples collected from patients with central retinal vein occlusion (n=58) and group of healthy volunteers (n=30) were analyzed using a proteomic label-free absolute quantitative ap-proach. We found a large proportion (458 proteins with a frequency > 0.6) of tear proteome shared between healthy donors and subjects with the central retinal vein occlusion (CRVO). Comparative proteomic analysis revealed 29 proteins (p<0.05) significantly differed in their quantitative property between CRVO patients and the control group. Among them S100A6 (log (2)FC = 1.11, p<0.001), S100A8 (log(2)FC = 2.45, p<0.001), and S100A9 (log2(FC) = 2.08, p<0.001) are the most abundantly represented upregulated proteins, and β2-microglobulin was the most downregulated protein (log2(FC) = -2.13, p<0.001). Mesothelin (MSLN) was found as a protein with a significant increase (log2(FC) = 0.82, p<0.001) in the CRVO group. The selected up- and downregulated pro-teins were assembled to customize map of the CRVO-related critical protein interactions with quantitative properties. The customized map (FDR<0.01) emerged inflammation, impairment of retinal hemostasis, and immune response as the main set of processes associated with CRVO is-chemic condition. The semantic analysis encouraged the prevalence of core biological processes encompassing dysregulation of mitochondrial organization and regulation of improperly or utilization of topologically incorrect folded proteins as a consequence of oxidative stress and in-flammation escalating the ischemic condition caused by the local retinal hemostasis dysregulation. The most significantly different proteins (S100A6, S100A8, S100A9, MSLN, and β2-microglobulin) were applied for the ROC plotting and their AUC varied from 0.772 to 0.952 suggesting association with the CRVO.

Metaproteomic assessment of gut microbial and host functional perturbations in Helicobacter pylori-infected patients subjected to an antimicrobial protocol

Project description:The impact of therapeutic interventions on the human gut microbiota (GM) is a clinical issue of paramount interest given the strong interconnection between microbial dynamics and human health. Orally administered antibiotics are known to reduce GM biomass and modify GM taxonomic profile. However, the impact of antimicrobial therapies on GM functions and biochemical pathways has scarcely been studied. Here, we characterized the fecal metaproteome of 10 Helicobacter pylori-infected patients before (T0) and after 10 days (T1) of a successful quadruple therapy (bismuth, tetracycline, metronidazole, and rabeprazole) and 30 days after therapy cessation (T2), to investigate how GM and host functions change during the eradication and healing processes. At T1, the abundance ratio between microbial and host proteins was reversed compared with that at T0 and T2. Several pathobionts (including Klebsiella, Proteus, Enterococcus, Muribaculum, and Enterocloster) were increased at T1. Therapy reshaped the relative contributions of the functions required to produce acetate, propionate, and butyrate. Proteins related to the uptake and processing of complex glycans were increased. Microbial cross-feeding with sialic acid, fucose, and rhamnose was enhanced, whereas hydrogen sulfide production was reduced. Finally, microbial proteins involved in antibiotic resistance and inflammation were more abundant after therapy. Moreover, a reduction in host proteins with known roles in inflammation and H. pylori-mediated carcinogenesis was observed. In conclusion, our results support the use of metaproteomics to monitor drug-induced remodeling of GM and host functions, opening the way for investigating new antimicrobial therapies aimed at preserving gut environmental homeostasis.
