Article Abstract

Mass spectrometry-based proteomics allows for the measurement of hundreds to thousands of proteins in a biological system. Additionally, mass spectrometry can also be used to quantify proteins and peptides. However, observing quantitative differences between biological systems using mass spectrometry-based proteomics can be challenging because it is critical to have a method that is fast, reproducible, and accurate. Therefore, to study differential protein expression in biological samples labeling or label-free quantitative methods can be used. Labeling methods have been widely used in quantitative proteomics, however label-free methods have become equally as popular and more preferred because they produce faster, cleaner, and simpler results. Here, we describe the methods by which proteins are isolated and identified from cochlear sensory epithelia tissues at different ages and quantitatively differentiated using label-free mass spectrometry.

Proteo-SAFARI is a shiny application for fragment assignment by relative isotopes, an R-based software application designed for identification of protein fragment ions directly in the / domain. This program provides an open-source, user-friendly application for identification of fragment ions from a candidate protein sequence with support for custom covalent modifications and various visualizations of identified fragments. Additionally, Proteo-SAFARI includes a nonnegative least-squares fitting approach to determine the contributions of various hydrogen shifted fragment ions ( + 1, + 1, - 1, - 2) observed in UVPD mass spectra which exhibit overlapping isotopic distributions.

Chronic hepatitis B virus (HBV) infection can significantly increase the incidence of cirrhosis and liver cancer, and there is no curative treatment. The persistence of HBV covalently closed circular DNA (cccDNA) is the major obstacle of antiviral treatments. cccDNA is formed through repairing viral partially double-stranded relaxed circular DNA (rcDNA) by varies host factors.

The death and clearance of nurse cells is a consequential milestone in Drosophila melanogaster oogenesis. In preparation for oviposition, the germline-derived nurse cells bequeath to the developing oocyte all their cytoplasmic contents and undergo programmed cell death. The death of the nurse cells is controlled non-autonomously and is precipitated by epithelial follicle cells of somatic origin acquiring a squamous morphology and acidifying the nurse cells externally.

The supramolecular binding exclusively by H-bonds of SeO, MoO and WO ions to form nanojars of the formula [EO⊂{-Cu(μ-OH)(μ-pz)}] (; E = Se, Mo, W; = 28-34; pz = pyrazolate) was studied in solution by electrospray ionization mass spectrometry, variable temperature, paramagnetic H NMR and UV-vis spectroscopy, and in the solid state by single-crystal X-ray crystallography. These large anions allow for the observation of a record nanojar size, (E = Mo, W). Six crystal structures are described of nanojars of varying sizes with either SeO, MoO or WO entrapped ions, including the first example of a cocrystal of two different nanojars in crystallographically unique positions, and .

Addressing the global challenge of ensuring access to safe drinking water, especially in developing countries, demands cost-effective, eco-friendly, and readily available technologies. The persistence, toxicity, and bioaccumulation potential of organic pollutants arising from various human activities pose substantial hurdles. While high-performance liquid chromatography coupled with high-resolution mass spectrometry (HPLC-HRMS) is a widely utilized technique for identifying pollutants in water, the multitude of structures for a single elemental composition complicates structural identification.
