DARS2 Promotes Tumorigenesis and Metastasis by Activating PI3K/Akt/GSK‐3β/β‐Catenin Signaling Pathway in Breast Cancer

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Aspartyl‐tRNA synthetase 2 (DARS2), the mitochondrial enzyme responsible for aminoacylation of aspartyl‐tRNA, is traditionally known for its effect on protein synthesis. Recently, DARS2 is reported to be implicated in tumorigenesis. However, its specific effect on breast cancer (BC) is poorly understood.

Ion Activation Methods for Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

open access: yesMedicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential

Repurposing antimicrobial agents for neuroprotection: Mechanisms, clinical potential, and challenges

open access: yesNeuroprotection, EarlyView.
Antimicrobial agents exert neuroprotective effects through modulation of interconnected pathways. Tetracyclines, macrolides, antimalarial agents, sulfones, and antiparasitic agents suppress neuroinflammation, oxidative stress, and apoptosis while preserving mitochondrial function and neurotransmission.
