Total protein of the yeast Issatchenkia orientalis was extracted and separated by two-dimensional electrophoresis (2-DE) before and after the dye Reactive Brilliant Red K-2BP was degraded by this yeast, respectively. Different protein extraction methods, different volumes of sample loaded and different staining techniques were tested and compared for the 2-DE. Among three different protein extraction methods, the final protein concentrations of 3.4 mg/mL, 1.8 mg/mL and 5.6 mg/mL were obtained by single ultrasonication, ultrasonication-TCA/acetone,and ultrasonication-ammonium sulfate precipitation, respectively. The best electrophoresis pattern could be gotten by loading 150 microg protein samples from the method of ultrasonication-ammonium sulfate precipitation, using IPG strips of pH 4-7 for the first dimensional electrophoresis and staining with silver nitrate. This electrophoresis pattern had high resolution and good repetition. It was detected to have 730 +/- 30 protein points by preliminary image analysis. This research results provided a technical support for screening dye-degrading enzymes from the yeast of I. orientalis.

The pathophysiology of arrhythmogenic cardiomyopathy (ACM), previously known as arrhythmogenic right ventricular cardiomyopathy (ARVC), and its specific biological features remain poorly understood. High-throughput plasma proteomic profiling, a powerful tool for gaining insights into disease pathophysiology at the systems biology level, has not been used to study ACM. This study aimed at characterizing plasmatic protein changes in patients with ACM, which were compared with those of healthy controls, and at exploring the potential role of the identified proteins as biomarkers for diagnosis and monitoring.

The primary mode of transmission for Chagas disease is vector-borne transmission, spread by hematophagous insects of the subfamily. In Mexico, the triatomine is particularly significant in the transmission of . This study focused on analyzing protein expression and modifications by glycosylation in different regions of the digestive tract of fifth-instar nymphs of .

Introduction: Recent work identified members of the evolutionarily conserved coronin protein family as key regulators of cell population size. This work originated ~25 years ago through the identification, by two-dimensional gel electrophoresis, of coronin 1 as a host protein involved in the virulence of . We here describe the journey from a spot on a 2D gel to the recent realization that coronin proteins represent key controllers of eukaryotic cell population sizes, using ever more sophisticated proteomic techniques.

A comprehensive strategy, including spectroscopic, molecular simulation, proteomics, and bioinformatics techniques, was employed to investigate a novel triazole, 5-(4-methoxyphenyl)-1-phenyl-1H-1,2,3-triazole, its interactions with high-abundance blood proteins, and identification of low-abundance proteins. The binding constants and thermodynamic parameters of the triazole to two high-abundance blood globular proteins, human serum albumin, and human immunoglobulin G (HIgG), were obtained by spectroscopic techniques and computational chemistry. The two-dimensional gel electrophoresis in combination with matrix-assisted laser desorption/ionization time-of-flight mass spectrometry was employed to isolate and identify differentially expressed low-abundance proteins in human blood serum samples following exposure to the triazole.

Western flower thrips, Frankliniella occidentalis (Thysanoptera: Thripidae) is an invasive agricultural pest with developed resistance to abamectin in some strains due to frequent treatment with the pesticide. In this study, we examined differentially expressed proteins (DEPs) between abamectin-resistant (Aba; under abamectin selective pressure) and susceptible strains (Aba; without abamectin selective pressure) of F. occidentalis.
