AI-2 combined with Lactobacillus rhamnosus GG remodels gut microbiota structure to alleviate intestinal oxidative stress injury in a mouse necrotizing enterocolitis model

Journal of Translational Medicine
Background Necrotizing enterocolitis (NEC) is a devastating intestinal disease primarily affecting preterm infants. This study aimed to explore the efficacy of Lactobacillus rhamnosus GG (LGG) combined with quorum-sensing molecule autoinducer-2 (AI-2) in

Recent advances in understanding pathophysiology of non-nutritional stunting in very preterm infants [PDF]

Clinical and Experimental Pediatrics
Very preterm infants (VPIs) often experience extrauterine growth failure. Therefore, aggressive nutritional management of VPIs is recommended with the goal of achieving the postnatal growth of an equivalent fetus.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Alterations in Metabolites Associated With Umbilical Cord Blood in Monozygotic Twins Discordant for Congenital Heart Disease

Pediatric Discovery
The specific mechanisms and screening methods for congenital heart disease (CHD) remain elusive. Evidence indicates that aberrant maternal metabolomic profiles are associated with CHD, but it is uncertain whether such an association exists in umbilical ...

The ubiquitin system in normal and infected germinal center B cells

FEBS Letters, EarlyView.
The ubiquitin system plays a central role in germinal center (GC) B cells, influencing differentiation to long‐lived memory B cells. Oncogenic gammaherpesviruses gain access to memory B cells by establishing latency in GC B cells. Mapping ubiquitin mechanisms in normal and infected GC B cells will define specific molecular circuits in B cells germane ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Lysyl oxidase (LOX)‐mediated remodeling of the extracellular matrix

FEBS Letters, EarlyView.
The lysyl oxidase (LOX) family of enzymes drives extracellular matrix remodeling by oxidizing collagen, elastin, and fibronectin, promoting covalent cross‐link formation. This activity regulates tissue architecture and mechanical properties, while its dysregulation contributes to fibrosis, cardiovascular disease, glaucoma, connective tissue disorders ...

Smaller is better: nanobodies meet NMR

FEBS Letters, EarlyView.
Nanobodies are single‐domain antigen‐binding fragments derived from camelid heavy chain antibodies. Their small size, high stability, and exceptional specificity make nanobodies uniquely useful probes for NMR studies of protein dynamics, transient conformational states, and protein–protein interactions.

Growth trajectories in exclusively breastfed infants with clinically diagnosed food allergy: a prospective longitudinal cohort study

Frontiers in Nutrition
BackgroundFood allergy (FA) in infancy may be accompanied by feeding difficulties and dietary modifications during breastfeeding, which may influence early growth.

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.
