Model Organisms in Aging Research: Evolution of Database Annotation and Ortholog Discovery.
Genes (Basel)
December 2024
Institute of Biomedical Chemistry, 119121 Moscow, Russia.
Background: This study aims to analyze the exploration degree of popular model organisms by utilizing annotations from the UniProtKB (Swiss-Prot) knowledge base. The research focuses on understanding the genomic and post-genomic data of various organisms, particularly in relation to aging as an integral model for studying the molecular mechanisms underlying pathological processes and physiological states.
Methods: Having characterized the organisms by selected parameters (numbers of gene splice variants, post-translational modifications, etc.

Bacterial endospores are ubiquitous and are responsible for various human infections. Recently, we reported that an ionic liquid (IL)-based sample preparation method (named pTRUST) facilitated highly efficient shotgun analysis of the Bacillus subtilis spore proteome in trace samples. In this study, we evaluated the efficiency and applicability of the pTRUST technology using three different spore preparations: one purified from the closely related subspecies B.

Techniques that enable precise manipulations of subsets of neurons in the fly central nervous system (CNS) have greatly facilitated our understanding of the neural basis of behavior. Split-GAL4 driver lines allow specific targeting of cell types in and other species. We describe here a collection of 3060 lines targeting a range of cell types in the adult CNS and 1373 lines characterized in third-instar larvae.

Toxins (Basel)
January 2025
Department of Experimental Pathology, Federal University of São João del-Rei, Divinópolis 36301-158, Brazil.
The discovery of novel cytotoxic drugs is of paramount importance in contemporary medical research, particularly in the search for treatments with fewer side effects and higher specificity. Antimicrobial peptides are an interesting class of molecules for this endeavor. In this context, the LyeTx III, a new peptide extracted from the venom of the spider, stands out.

Front Pharmacol
January 2025
Department of Neurology, Dongzhimen Hospital, Beijing University of Chinese Medicine, Beijing, China.
Background: Migraine represents a chronic neurological disorder characterized by high prevalence, substantial disability rates, and significant economic burden. Its pathogenesis is complex, and there is currently no cure. The rapid progress in multi-omics technologies has provided new tools to uncover the intricate pathological mechanisms underlying migraine.
