How Growth Cones Sense Extracellular Cues and Drive Neuronal Migration
Migrating neurons and growing axons utilize structurally and functionally similar growth cones to detect guidance cues. Shared receptors and signaling pathways mediate cytoskeletal reorganization to direct movement. This conserved mechanism underlies both neuronal migration and axon extension, providing insights into neuronal development and potential ...

Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...

Ubiquitination in cancer: mechanisms and therapeutic opportunities
Abstract Ubiquitination, a key post‐translational modification, plays an essential role in tumor biology by regulating fundamental cellular processes, such as metabolism and cell death. Additionally, it interacts with other post‐translational modifications, which are closely linked to tumorigenesis, tumor progression, the tumor microenvironment, and ...

Abstract Post‐translational modifications (PTMs) play a pivotal role in epigenetic regulation and are key pathways for modulating protein functionality. PTMs involve the covalent attachment of distinct chemical groups, such as succinyl, crotonyl, and lactyl, at specific protein sites, which alter protein structure, function, stability, and activity ...

Promising Prodiginins Biological Activities
ABSTRACT Prodiginins are a large family of at least 34 pyrrolic compounds, including the well‐studied red pigment prodigiosin. Prodiginins are produced by several microorganisms displaying broad biological activities, including antimicrobial, antiviral, antiparasitic, antiproliferative, and immunosuppressive activities.

Internal Ubiquitin Electrophiles for Covalent Trapping and Inhibition of Deubiquitinases
GA: Genetically encoded internal electrophiles in ubiquitin (Ub) enable the profiling of multivalent interaction interfaces, addressing a key limitation of current Ub‐based activity‐based probes. In this study, these probes capture a Ub–deubiquitinase interaction with minimal structural perturbation and serve as selective diUb probes that covalently ...

LZTS2 Negatively Regulates Centrosomal CEP135 Levels and Microtubule Nucleation
ABSTRACT The microtubule cytoskeleton is a fundamental functional component of the cell. In vertebrate proliferating cells, centrosomes are the primary microtubule organizing center (MTOC), and their dysregulation has been linked to genomic instability and cancer.

Ubiquitin‐specific protease 7 (USP‐7) is a novel target for anticancer therapy. To further extend the structure–activity relationships of the previously USP‐7 inhibitor STIRUR‐41, a library of 5‐aminopyrazoles is reported. 1d shows a potency comparable to lead compound STIRUR‐41 and promising in silico and in vitro pharmacokinetic properties ...

NSAIDS AS MODULATORS OF CATION CHANNELS: FENAMATES REPURPOSING IN CHANNELOPATHIES
Cationic ion channels are transmembrane proteins that regulate the flux of cations (potassium, sodium, and calcium) across cell membrane, playing a pivotal role in many cellular functions. Disruptions of their activity can lead to the so‐called genetic or acquired channelopathies, a heterogeneous group of diseases that affect multiple human systems ...
