Hyperosmotic stress‐induced redistribution of pre‐mRNA cleavage factor I subunits is associated with shifts in alternative polyadenylation

FEBS Open Bio, EarlyView.
Hyperosmotic stress triggers the relocation of the CFIm complex from the nucleus to the cytoplasm. This shift creates a nuclear ‘stoichiometric bottleneck’, limiting CFIm availability for mRNA processing. Consequently, specific mRNAs like NUDT21 and DICER1 undergo targeted 3′UTR shortening, demonstrating how spatial protein dynamics drive rapid ...

Uncovering the effects of grazing exclusion duration on plant richness and biomass in alpine grasslands using the price equation

Frontiers in Plant Science
Grazing exclusion is a key strategy for restoring degraded alpine grasslands. However, the mechanisms underlying plant species richness and biomass responses to long-term enclosure, particularly species turnover and biomass redistribution, remain unclear.

Exploring the influence of lactoferrin on wound healing and related signaling pathways: a systematic review

FEBS Open Bio, EarlyView.
Lactoferrin promotes wound healing by activating MAPK, PI3K/Akt, and extracellular matrix pathways, enhancing fibroblast remodeling, proliferation, and re‐epithelialization. These mechanisms highlight its therapeutic potential in inflammation control, tissue repair, and remodeling.

Multiscale patterns of sponge diversity on Western Atlantic coral reefs: insights from the Southern Gulf of Mexico and the Mexican Caribbean

Frontiers in Marine Science
IntroductionSponges are increasingly dominant components of coral reefs in the Tropical Western Atlantic, yet patterns of their diversity across spatial scales remain poorly quantified.MethodsWe applied a hierarchical sampling design across 13 reefs and ...

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

Plant Biodiversity Along a Protection-Coverage Gradient in the Baekdudaegan Protected Area, South Korea

Diversity
Assessing biodiversity within protected areas requires consideration of not only the extent of protection but also multiple dimensions of biodiversity, including species richness, composition, and turnover.

Tama-risk? Avian responses to the invasion of saltcedars (Tamarix ramosissima) in Sonora, Mexico

Revista Mexicana de Biodiversidad, 2013
Although exotic plant invasions are one of the most important components of global change, previous studies have found some of the alien species to provide resources and/or conditions to native biota.

A minimal cellulosome‐like system in Cellulosilyticum lentocellum

FEBS Open Bio, EarlyView.
Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

Altitudinal patterns and seasonal stability in the avifauna of Cerro Chucantí, Panama

Acta Zoológica Lilloana
Darién combines humid lowland and montane forests with high endemism, but these ecosystems are increasingly threatened by deforestation, agriculture, cattle ranching, and logging.
