Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

SIRT1/PGC-1α-regulated mitochondrial biogenesis is involved in T-2 toxin-induced chondrocyte injury

Ecotoxicology and Environmental Safety
T-2 toxin, a type A trichothecene mycotoxin, has been implicated as an environmental risk factor for Kashin-Beck disease (KBD), an endemic osteoarthropathy characterized by cartilage damage.

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Autophagy and mitophagy in pancreatic β‐cell homeostasis and their involvement in diabetes pathophysiology

FEBS Letters, EarlyView.
This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.

T-2 toxin-induced spatial learning and memory impairment in mice via the gut-brain axis and the intervening effects of resveratrol

Ecotoxicology and Environmental Safety
T-2 toxin, classified as a mycotoxin, harms immune and cognitive systems. Recently, an increasing number of studies have focused on the neurotoxic effects of T-2 toxin. However, there is still a need for a better understanding of the molecular mechanisms

Emerging experimental and computational methods for studying redox‐regulated structural transitions

FEBS Letters, EarlyView.
Redox reactions can reshape proteins and alter how they behave in cells, with important consequences for health and disease. This review explores emerging experimental and computational approaches for discovering these redox‐sensitive protein switches, revealing their structural effects, and predicting their behavior, opening new opportunities to ...

Betulinic Acid Ameliorates T-2 Toxin-Induced Neuroinflammation by Suppressing Oxidative Stress via Regulating Nrf2/NLRP3 Axis

Veterinary Sciences
T-2 toxin is widely present in agricultural products and poses a significant neurotoxicity threat. Betulinic acid (BA), a natural triterpenoid, exhibits strong antioxidant and anti-inflammatory properties.

Effect of T-2 Toxin in Combination with Vitamin E, Selenium and Mycotoxin Binder on Lipid Peroxide Status and on the Glutathione Redox System in Broiler Chicken

The Journal of Poultry Science, 2006
The effect of T-2 toxin (2.35mg/kg of feed) on lipid peroxidation and on the antioxidant defence system was studied in blood plasma, red blood cells (RBC), liver and spleen of broiler chickens. The influences of antioxidant vitamin E (10.5mg/animal/day)+

Synergistic perspectives—How single‐molecule biophysics complement biochemical understanding

FEBS Letters, EarlyView.
In this review, we discuss how ensemble biochemistry and single‐molecule approaches are complementary, outline commonly used single‐molecule techniques, and illustrate their relevance through two representative case studies: chromatin organization by SMC complexes and pathway choice during DNA double‐strand break repair.
