Proteostasis of organelles in aging and disease
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

The eukaryote‐specific N‐terminal domain (NTD) of eS31 uses two distinct strategies to maintain translation fidelity. During elongation, a positively charged “hotspot” fine‐tunes the selection of incoming aa‐tRNA. During termination, the entire NTD acts as a structural scaffold to ensure the correct positioning of the release factor eRF1.

Fragile X messenger ribonucleoprotein 1 (FMRP) is a multidomain RNA‐binding protein associated with Fragile X Syndrome (FXS). We found that its N‐terminal structured region has an intrinsic propensity to undergo liquid–liquid phase separation and fibril formation. FXS‐associated mutations perturb protein stability and aggregation propensity, suggesting

Serum miR‐224‐5p levels are progressively elevated in diabetic nephropathy (DN) and serve as an independent predictor of a decline in eGFR of ≥30% over 2 years. Mechanistically, miR‐224‐5p directly targets PTEN 3’‐UTR, suppressing PTEN and the activation of the AKT pathway in high‐glucose‐stimulated mesangial cells.

Abstract Background Although systemic lupus erythematosus (SLE) pregnancy frequently results in small for gestational age (SGA) infants, the understanding of underlying mechanisms is limited. We aimed to identify specific histological patterns of placental injury in SGA in SLE and to explore whether an altered balance of angiogenesis‐related proteins ...

Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.

Abstract Prolonged bed rest and immobilization have deleterious effects on skeletal muscle mass and function, especially in older adults. These can lead to reduced physical capacity and quality of life. Previous experiments in younger individuals show that exercise can mitigate these effects, but evidence remains scarce and inconclusive in older adults.

Circular RNAs: Unlocking new avenues in cardiometabolic disease management
Abstract figure legend In the heart circular RNAs (circRNAs) function as microRNA sponges, interact with proteins and can even undergo translation. Advances in bioinformatics now enable their identification through high‐throughput RNA sequencing, whereas computational analyses reveal differential expression in cardiac disease settings.

Impaired Motor Function in a Zebrafish Stathmin‐2 Knockout Model
ABSTRACT Stathmin‐2 (STMN2) is a microtubule‐associated protein that plays a role in the stability of microtubules in axons of the nervous system of animals. In this study, we generated a novel zebrafish STMN2 knockout (KO) model. STMN2 is represented by two genes in the zebrafish genome: stmn2a and stmn2b.
