Coenzyme A mitigates cystine‐deprivation‐induced ferroptosis by suppressing the iron‐starvation response

open access: yesThe FEBS Journal, EarlyView.
Cystine (Cys2) deprivation in pancreatic cancer cells induces oxidative stress that destabilizes cytosolic iron–sulfur cluster (ISC) proteins, triggering an iron‐regulatory protein (IRP)‐mediated iron‐starvation response (ISR). This leads to increased iron uptake (via TFRC), an expanded labile iron pool, and ferroptosis.

Phosphorylation Inactivates Escherichia coli Isocitrate Dehydrogenase by Preventing Isocitrate Binding

open access: yesJournal of Biological Chemistry, 1989
Equilibrium binding studies demonstrate that purified Escherichia coli isocitrate dehydrogenase binds isocitrate, alpha-ketoglutarate, NADP, and NADPH at 1:1 ratios of substrate to enzyme monomer. The phosphorylated enzyme, which is completely inactive, is unable to bind isocitrate but retains the ability to bind NADP and NADPH.

Ontogeny of escape response and body shape in threespine stickleback (Gasterosteus aculeatus L.)

open access: yesJournal of Fish Biology, EarlyView.
Abstract Escape responses in fishes provide insight into accelerative motions and behavioural response times of these animals, linking numerous fitness‐related traits. We sought to connect escape response performance to genotype and phenotype across ontogenetic stages within a single population of threespine stickleback (Gasterosteus aculeatus L.) to ...

Epigenetic Regulation in the Pathogenesis of Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
The aim of this narrative literature review was to identify epigenetic marks associated with periodontitis and to place them in a biological context. The literature was reviewed based on pre‐defined criteria. Cell type specific chromatin and mRNA modifications were included.

Multi‐Omics Combined With Mitochondrial Feeding Assays Reveal a Novel Energy Metabolism Strategy for Floral Thermogenesis in Magnolia Driven by Synergistic Supply of Multiple Substrates

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT The high demand for energy during floral thermogenesis drives the synergistic operation of multiple energy substrates for the rapid temperature rise and successful reproduction of flowers. However, how thermogenic plants precisely regulate substrate supply and metabolic pathways within a short time to support large‐scale energy and heat ...

Comparative proteomics analysis of root and nodule mitochondria of soybean

open access: yesPlant, Cell &Environment, EarlyView.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Contextualized Metabolic Modelling Revealed Factors Affecting Isoflavone Accumulation in Soybean Seeds

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Isoflavones, secondary metabolites with numerous health benefits, are predominantly found in legume seeds, especially soybean; however, their contents in domesticated soybean seeds are highly variable. Wild soybeans are known for higher seed isoflavone contents than cultivars. Here we used experimental and modelling approaches on wild soybean (

Polo‐like kinases and UV‐induced skin carcinogenesis: What we know and what's next

open access: yesPhotochemistry and Photobiology, EarlyView.
The polo‐like kinase (PLK) family plays distinct and critical roles in the regulation of cell cycle progression, and its dysregulation has been implicated in various cancers. Ultraviolet (UV) radiation is a well‐established environmental factor in the development of skin cancer.

Neuronal loss of the pentose phosphate pathway in the living nervous system is causally linked to [NADPH] reduction and elevated oxidative stress

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Using genetically encoded sensors for NADPH and H2O2 in the living Drosophila nervous system, neuron‐specific PPP knockdown is shown to result in reduced neuronal NADPH levels and elevated neuronal H2O2 levels and oxidative stress.
