Comparative analysis of metabolic and functional cardiac alterations in diet‐ and genetically induced mouse models of cardiac dysfunction

The FEBS Journal, EarlyView.
Dietary and genetic stress trigger different routes to heart failure. In mice, a carbohydrate‐free high‐fat diet caused mitochondrial dysfunction and impaired energy production with preserved pumping function, while genetic obesity led to heart enlargement, fibrosis, and reduced function.

Shikimate pathway disruption in yeast induces metabolite self‐assembly into toxic aggregates

The FEBS Journal, EarlyView.
In Saccharomyces cerevisiae, shikimate pathway disruption induces toxic metabolite assemblies. Deleting ARO4 plus phenylalanine (Phe) feeding causes Phenylalanine accumulation, lowers ARO3 activity, and triggers amyloid‐like fibril formation. Deleting ARO3 plus tyrosine (Tyr) feeding leads to Tyrosine buildup and similar fibril assembly.

Intrinsic specificity of a ‘core’ TIP60 acetyltransferase complex in Drosophila

The FEBS Journal, EarlyView.
The intrinsic substrate selectivity of the Drosophila TIP60‐core acetyltransferase was determined using synthetic nucleosome arrays. Targeted mass spectrometry revealed site‐specific acetylation of histones H2A, H2A.V, and H4, uncovering distinct acetylation rates and patterns across individual lysines.

Lock, relax, load, and shoot: a molecular perspective on Nedd4 regulation

The FEBS Journal, EarlyView.
Structural basis of inactive and active states of the Nedd4 HECT E3 ligase subfamily, following a ‘lock, relax, load, and shoot’ mechanism. In the locked, autoinhibited state, intramolecular domain interactions restrain the HECT domain. Relaxation releases these restraints, allowing loading of ubiquitin onto the catalytic cysteine, followed by the ...

Energetic stress in combination with impaired fatty acid oxidation induces sequestration of CoA and adaptation of CoA metabolism

The FEBS Journal, EarlyView.
Computational modelling and in vitro liver cell experiments indicate that medium‐chain acyl‐CoA dehydrogenase (MCAD) deficiency causes an accumulation of (especially medium‐chain) acyl‐CoAs at the cost of free CoA (CoASH). A substantial decrease in CoASH impairs flux through many pathways essential for energy homeostasis.
