Comparative analysis of platelet-derived extracellular vesicles protein extraction methodologies for mass spectrometry 

ABSTRACT: This study presents a comparative study of different methodologies for the extraction of proteins from platelet derived-extracellular vesicles (pEV) prior to subsequent mass spectrometry (MS) analysis. Protein isolation is performed through three different methodologies based on SDS-polyacrylamide gel electrophoresis (SDS-PAGE), organic solvent precipitation (OSP) or magnetic beads (MB), followed by protein digestion and sample acquisition by LC-MS/MS.

The aim of this study is to present a comparative study of different methodologies for the extraction of proteins from platelet-derived extracellular vesicles (pEVs) prior to subsequent mass spectrometry (MS) analysis. pEVs were isolated by size exclusion chromatography (SEC) from human platelet lysates (PL) and characterized by identifying specific markers by Western blot, visualizing morphology by transmission electron microscopy (TEM) and analyzing concentration and size via nanoparticle trac ...[more]

Project description:Hydrogen sulfide (H2S) is a signaling molecule that regulates essential plant processes, such as autophagy and responses to abiotic stresses. Although there is much information about the processes in which H2S is involved, the mechanism of action of H2S is still unclear. However, the posttranslational modification of cysteine residues, named persulfidation, is the main proposed mechanism. In this study, the role of H2S during drought that allows plant stress adaptation has been analyzed, with the focus on the underlying mechanism. H2S pretreatment before imposing drought on plants significantly improved phenotypic traits and decreased the content of biochemical and molecular drought stress markers. In addition, H2S regulated amino acid metabolism and repressed drought-induced degradation pathways, such as bulk autophagy and protein ubiquitination. The label-free quantitative proteomic analysis of plants growing under control and drought stress identified 887 proteins significantly different persulfidated between both conditions. Bioinformatic analyses revealed that the biological processes most enriched containing the proteins more persulfidated in drought corresponded to cellular response to oxidative stress, and hydrogen peroxide catabolism. In addition, protein degradation, abiotic stress responses, anthocyanin-containing compound biosynthetic process, and flavonoid biosynthesis were highlighted. On the contrary, the most enriched biological process containing proteins with lower levels of persulfidation in drought corresponded to the biosynthetic processes of glucosinolates and chlorophyll. Therefore, our findings emphasize the role of H2S as a promoter of enhanced tolerance to drought, enabling plants to respond more rapidly and efficiently after exposure to drought. Furthermore, the proteomic analysis supports the main role of protein persulfidation as the molecular mechanism of H2S to alleviate ROS accumulation and balance redox homeostasis under drought stress.

Project description:The seminal plasma (SP) is the liquid component of semen that facilitates sperm transport through the female genital tract. SP modulates the activity of the ovary, oviductal environment and uterine function during the periovulatory and early pregnancy period. Extracellular vesicles (EVs) secreted in the oviduct (oEVs) and uterus (uEVs) have been shown to influence the expression of endometrial genes that regulate fertilization and early embryo development. In some species, semen is composed of well-separated fractions that vary in concentration of spermatozoa and SP composition and volume. This study aimed to investigate the impact of different accumulative fractions of the porcine ejaculate (F1, composed of the sperm-rich fraction (SRF); F2, composed of F1 plus the intermediate fraction; F3, composed of F2 plus the post-SRF) on oEVs and uEVs protein cargo. Six days after the onset of estrus, we determined the oEVs and uEVs size and protein concentration in pregnant sows by artificial insemination (AI-sows) and in non-inseminated sows as control (C-sows). We also identified the main proteins in oEVs and uEVs, in AI-F1, AI-F2, AI-F3, and C-sows. Our results indicated that although the size of EVs is similar between AI- and C-sows, the protein concentration of both oEVs and uEVs was significantly lower in AI-sows (p < 0.05). Proteomic analysis identified 38 unique proteins in oEVs from AI-sows, mainly involved in protein stabilization, glycolytic and carbohydrate processes. The uEVs from AI-sows showed the presence of 43 unique proteins, including already-known fertility-related proteins (EZR, HSPAA901, PDS). We also demonstrated that the protein composition of oEVs and uEVs differed depending on the seminal fraction(s) inseminated (F1, F2, or F3). In conclusion, we have found a specific protein cargo in uterine and oviductal EVs depending on the type of semen fraction the sow was inseminated with, and these insemination with different seminal fractions results in the oviductal and uterine secretion of specific EVs proteins are closely associated with reproductive processes.
