From Model to Practice: Testing Near‐Infrared Spectroscopy as a Bone Collagen Prescreening Tool

Archaeometry, EarlyView.
ABSTRACT Collagen is a vital archaeological material, preserving biochemical signatures that provide insights into past environments, diets, and human–animal interactions. However, diagenetic processes can lead to rapid and often inconspicuous degradation of collagen. Given the variability in collagen preservation and its significance for analyses such

Inhibition of the NR4A1‐mediated cell cycle checkpoint enhances hyperplastic adipogenesis and glucose homeostasis in obesity

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose The nuclear receptor NR4A1 is a critical node in transcriptional circuits for metabolic adaptation, yet its role in adipocyte progenitor (AP) fate and proliferation is unclear. We sought to define how NR4A1 governs early adipogenesis and adipose tissue plasticity.

DNA Stable Isotope Probing Mehod to Examine Carbon Assimilation in Stream Biofilms

, 2017
DNA stable isotope probing (DNA-SIP) identifies microbial populations that assimilate a substrate of interest by tracking the movement of an isotopic label from a substrate into DNA. Although the technique has not been widely used in streams, DNA-SIP can

An inhibitor of the mitochondrial respiratory chain exerts synergistic anti‐tumour effects when combined with alkylating agents

British Journal of Pharmacology, EarlyView.
Background and Purpose Cancer cells exhibit the Warburg effect, but oxidative phosphorylation (OXPHOS) is also important for cancer cell proliferation. Metabolic reprogramming from glycolysis to OXPHOS is one mechanism of resistance to anti‐tumour drugs.

Directional information flow in human frataxin defines allosteric pathways connecting the hydrophobic core to the iron‐binding ridge

The FEBS Journal, EarlyView.
Human frataxin deficiency causes Friedreich's ataxia, yet how iron‐binding events are communicated across the protein is unclear. Using transfer entropy analysis of molecular dynamics simulations, we identify buried hydrophobic core leucines (LEU136, LEU140) as the source of directional signaling toward the iron‐binding acidic ridge.

The molecular basis of GshT substrate binding reveals how Streptococcus pneumoniae acquires the antioxidant glutathione

The FEBS Journal, EarlyView.
Streptococcus pneumoniae imports glutathione (GSH) from its obligate human host to defend against oxidative stress. GSH import is facilitated through the substrate binding protein (SBP) GshT, relying on charge complementarity between the protein and ligand.

Combining eDNA metabarcoding and stable isotope analysis advances diet studies in a colonial, non‐regurgitating seabird

Ibis, EarlyView.
Understanding seabird diet is fundamental to assessing trophic interactions and predicting responses to environmental change. However, seabird diet studies are often constrained by low taxonomic resolution, invasive sampling methods or reliance on opportunistically collected samples, leaving the diet of important populations such as Common Guillemots ...
