Chem Biol Interact

January 2025

Applied and Functional Genomics Lab, Centre of Excellence in Molecular Biology, University of the Punjab, Lahore Pakistan. Electronic address:

The death rate due to liver cancer approaches 2 million annually, the majority is attributed to fibrosis. Currently, there is no efficient, safe, non-toxic, and anti-fibrotic drug available, suggesting room for better drug discovery. The current study aims to evaluate the anti-fibrotic role of reserpine, an alkaloid plant compound against CCl-induced liver fibrosis.

January 2025

Autonomous University of Barcelona, Systematics and Evolution of Vascular Plants (UAB) - Associated Unit to CSIC by IBB - Cerdanyola del Vallès, Spain.

Widely distributed plant genera offer insights into biogeographic processes and biodiversity. The Carduus-Cirsium group, with over 600 species in eight genera, is diverse across the Holarctic regions, especially in the Mediterranean Basin, Southwest Asia, Japan, and North America. Despite this diversity, evolutionary and biogeographic processes within the group, particularly for the genus Cirsium, remain underexplored.

Background: Brugada syndrome (BrS) is a genetic heart disease that predisposes individuals to ventricular arrhythmias and sudden cardiac death. Although implantable cardioverter-defibrillators (ICDs) and quinidine are primary treatments, recurrent BrS-triggered ventricular arrhythmias can persist. In this setting, epicardial substrate ablation has emerged as a promising alternative for symptomatic patients.

Gastric cancer is a prevalent gastrointestinal tumor. In the classical cascade of gastric cancer development, the gradual progression from non-atrophic gastritis, atrophic gastritis, intestinal metaplasia, to intraepithelial neoplasia eventually leads to early gastric cancer. We investigated the proteomic characteristics of chronic gastritis (CG), low-grade intraepithelial neoplasia (low-grade LGIN), and early gastric cancer (EGC).

Department of Experimental Biology, Division of Genetics and Molecular Biology, Faculty of Science, Masaryk University, 611 37 Brno, Czech Republic. Electronic address:

The preparation of a solid dosage form containing bacteriophages, which meets pharmaceutical requirements and ensures long-term stability of the phage effect, is significant for implementing phage therapy in practice. A commonly used method for processing phages into a solid form is freeze-drying into a (so-called) freeze-dried cake; however, to date there have been no studies examining the pharmacopeial parameters of freeze-dried tablets with bacteriophages. In this study, we describe the preparation and properties of freeze-dried tablets containing a cocktail of purified pseudomonal bacteriophage DSM 33593 from the genus Pbunavirus and staphylococcal bacteriophage DSM 33473 from the genus Kayvirus (10 PFU/tablet) as the active ingredient.

Electronic address:

Cell microencapsulation technologies allow non-autologous implantation of therapeutic cells for sustained drug delivery purposes. The perm-selective membrane of these systems provides resistance to rupture, stablishes the upper molecular weight limit in bidirectional diffusion of molecules, and affects biocompatibility. Thus, despite being a decisive factor to succeed in terms of biosafety and therapeutic efficacy, little progress has been made in its optimization so far.

N-degrons are amino-terminal degradation signals. Non-acetylated first residues with bulky side chains were the first discovered N-degrons. In yeast, their ability to destabilize a protein depends on ubiquitin ligase Ubr1, which has a binding site for basic first residues, the UBR box, and one for hydrophobic first residues, the N domain.

Increasing evidence from fluid biopsies suggests activation and injury of glial cells in epilepsy. The prevalence of clinical and subclinical seizures in neurodegenerative conditions such as Alzheimer's disease, frontotemporal dementia, and others merits review and comparison of the effects of seizures on glial markers in epilepsy and neurodegenerative diseases with concomitant seizures. Herein, we revisit preclinical and clinical reports of alterations in glial proteins in cerebrospinal fluid and blood associated with various types of epilepsy.
