Decoupling enzyme catalysis from thermal denaturation [PDF]

open access: yes, 2010
The equilibrium model (EM) (Daniel et al., 2001) postulates two forms of a folded enzyme, one catalytically active (Eact) and the other inactive (Einact), which interconvert via a fast thermal equilibrium (Keq) (Figure A). This model for enzyme catalysis

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS 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

Design of minibinder proteins as universal antagonists against canine and human TNFα

open access: yesCommunications Biology
In this study, we resolve the complex structure of canine TNFα (cTNFα) trimer bound to nanobody molecules at a resolution of 3.1 Å using cryo-electron microscopy.

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

open access: yesFEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Antimicrobial potential of the combination of fulvic acid and Trichoderma asperellum against rice pathogens

open access: yesBiological Control
In this study, fluvic acid was prepared from sludge waste. The prepared fulvic acid had almost the same chemical structure as the standard compound expect that it contained a slightly more functional groups, which increased stability and biological ...
