Dietary non-phytate phosphorus and phytase interaction affects growth performance, mineral transportation and metabolism in broiler chickens

Poultry Science
The interaction effects of dietary non-phytate phosphorus (NPP) and phytase on growth performance, mineral metabolism, and gene expressions of mineral transporters in broilers duodenum and kidney (0-3 weeks) were studied. The levels of NPP (0.45 %, 0.35 %

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

MAPK signaling pathway participates in the regulation of intestinal phosphorus and calcium absorption in broiler chickens via 1,25-dihydroxyvitamin D3

Poultry Science
: Four experiments were performed to investigate the role of the mitogen-activated protein kinase (MAPK) signaling pathway in intestinal absorption of phosphorus (P) and calcium (Ca) in broiler chickens.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Electrical interface design for additively manufactured polymer anodes for biophotovoltaic systems

Frontiers in Microbiology
IntroductionReliable electrical interfacing between additively manufactured conductive polymer anodes and external circuits remains a key challenge in biophotovoltaic (BPV) systems, particularly due to debonding failures during operation. This study aims

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase

FEBS Letters, EarlyView.
Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Estimating Food Additive Intake: A Systematic Review of Intake and Nonlaboratory Methodologies

Food Frontiers
Despite increasing interest in the physiological and health effects of select additives (e.g., artificial food colors, emulsifiers, flavor enhancers, and preservatives), it is unclear whether there is a preferred nonlaboratory methodology for measuring ...
