January 2025

Atelier de Biologie Chimie Informatique Structurale, Centre de Biologie Structurale, Univ Montpellier, CNRS, INSERM, 29 rue de Navacelles, 34090 Montpellier, France.

Reduced nicotinamide adenine dinucleotide phosphate (NADPH) is a crucial reducing cofactor for reductive biosynthesis and protection from oxidative stress. To fulfill their heightened anabolic and reductive power demands, cancer cells must boost their NADPH production. Progrowth and mitogenic protein kinases promote the activity of cytosolic NAD kinase (NADK), which produces NADP, a limiting NADPH precursor.

The crowded bacterial cytoplasm is composed of biomolecules that span several orders of magnitude in size and electrical charge. This complexity has been proposed as the source of the rich spatial organization and apparent anomalous diffusion of intracellular components, although this has not been tested directly. Here, we use biplane microscopy to track the 3D motion of self-assembled bacterial genetically encoded multimeric nanoparticles (bGEMs) with tunable size (20 to 50 nm) and charge (-3,240 to +2,700 e) in live cells.

Transplanted organs are inevitably exposed to ischemia-reperfusion (IR) injury, which is known to cause graft dysfunction. Functional and structural changes that follow IR tissue injury are mediated by neutrophils through the production of oxygen-derived free radicals, as well as from degranulation which entails the release of proteases and other pro-inflammatory mediators. Neutrophil serine proteases (NSPs) are believed to be the principal triggers of post-ischemic reperfusion damage.

Semiconducting Overoxidized Polypyrrole Nano-Particles for Photocatalytic Water Splitting.

Small

January 2025

UMR 8182, CNRS, Institut de Chimie Moléculaires et des Matériaux d'Orsay, Université Paris-Saclay, Orsay, 91405, France.

Capturing sunlight to fuel the water splitting reaction (WSR) into O and H is the leitmotif of the research around artificial photosynthesis. Organic semiconductors have now joined the quorum of materials currently dominated by inorganic oxides, where for both families of compounds the bandgaps and energies can be adjusted synthetically to perform the Water Splitting Reaction. However, elaborated and tedious synthetic pathways are necessary to optimize the photophysical properties of organic semiconductors.

Recent advances in biocatalytic and chemoenzymatic synthesis of oligonucleotides.

Chembiochem

January 2025

Institut Pasteur, Department of Structural Biology and Chemistry, 28 Rue du Dr. Roux, 75015, Paris, FRANCE.

Access to synthetic oligonucleotides is crucial for applications in diagnostics, therapeutics, synthetic biology, and nanotechnology. Traditional solid phase synthesis is limited by sequence length and complexities, low yields, high costs and poor sustainability. Similarly, polymerase-based approaches such as in vitro transcription and primer extension reactions do not permit any control on the positioning of modifications and display poor substrate tolerance.

Background: Aromatic L-amino acid decarboxylase (AADC) deficiency is a rare life-threatening inborn error of neurotransmitter biosynthesis. It is characterized by deficient biosynthesis of neurotransmitters dopamine and serotonin, leading to catecholamines deficiency and sympathetic deprivation, while the parasympathetic system remains functional. Since 2012, gene therapy has led to clinical improvements in symptoms and motor function with a severe phenotype.

The clinical breakpoint for a drug-pathogen combination reflects the drug susceptibility of the pathogen wild-type population, the location of the infection, the integrity of the host immune response, and the drug-pathogen pharmacokinetic (PK)/pharmacodynamic (PD) relationship. That PK/PD relationship, along with the population variability in drug exposure, is used to determine the probability of target attainment (PTA) of the PK/PD index at a specified minimum inhibitory concentration (MIC) for a selected target value. The PTA is used to identify the pharmacodynamic cutoff value (CO), which is one of the three components used to establish the clinical breakpoint.

Background: There is a need to improve risk stratification of primary cutaneous melanomas to better guide adjuvant therapy. Taking into account that haematoxylin and eosin (HE)-stained tumour tissue contains a huge amount of clinically unexploited morphological informations, we developed a weakly-supervised deep-learning approach, SmartProg-MEL, to predict survival outcomes in stages I to III melanoma patients from HE-stained whole slide image (WSI).

Methods: We designed a deep neural network that extracts morphological features from WSI to predict 5-y overall survival (OS), and assign a survival risk score to each patient.

Previous studies have demonstrated legacy effects of current species distributions to past environmental conditions, but the temporal extent of such time lag dynamics remains unknown. Here, we have developed a non-equilibrium Species Distribution Modelling (SDM) approach quantifying the temporal extent that must be taken into account to capture 95% of the effect that a given time series of past environmental conditions has on the current distribution of a species. We applied this approach on the distribution of 92 European forest birds in response to past trajectories of change in forest cover and climate.

A metal-free dual photo- and organocatalytic decarbonylation of aliphatic aldehydes is described for the first time. On the one hand, a wide range of tertiary aldehydes are smoothly decarbonylated thanks to the combination of thioxanthone as photocatalyst and diphenyl disulfide as organocatalyst. On the other hand, by simply using 4-CzIPN as photocatalyst instead of thioxanthone, various secondary aldehydes readily undergo decarbonylation in an orthogonal manner, via the in situ formation of 1,4-dihydropyridines.

Effects of protection on large-bodied reef fishes in the western Indian Ocean.

Conserv Biol

January 2025

UMR ENTROPIE (IRD, UR, CNRS, IFREMER, UNC), CS 41096, La Reunion, France.

Predatory and large-bodied coral reef fishes have fundamental roles in the functioning and biodiversity of coral reef ecosystems, but their populations are declining, largely due to overexploitation in fisheries. These fishes include sharks, groupers, Humphead wrasse (Cheilinus undulatus), and Green Humphead parrotfish (Bolbometopon muricatum). In the western Indian Ocean, this situation is exacerbated by limited population data on these fishes, including from conventional visual census methods, which limit the surface area surveyed.

Centre de Recherche en Biologie cellulaire de Montpellier (CRBM), Université de Montpellier, Centre National de la Recherche Scientifique, Montpellier, France.

One widespread technique to assess in relative terms the amount of broken DNA present in the genome of individual cells consists of immobilizing the cell's nucleus under an agarose pad (called the nucleoid) and subjecting the whole genome to electrophoresis to force broken DNA molecules out of it. Since the migrating broken DNA molecules create a tail behind the nucleoid, this technique is named the comet assay. While performing comet assays regularly, we systematically observed circular regions devoid of DNA within the nucleoid region.
