Post-transcriptional regulation of ornithine decarboxylase in Xenopus laevis oocytes.

, 1990
International audienceThe level at which ornithine decarboxylase expression is regulated in growing oocytes has been investigated. Immunoprecipitation of the in vivo labelled proteins showed that ornithine decarboxylase accumulated less rapidly in stage ...

Brain viral reservoir seeding and neurological metabolic dysregulation in early‐life immunodeficiency virus infection

Brain Pathology, EarlyView.
Brain viral reservoirs were undetectable in neonatal SIV during the first 3 days post infection; antiretroviral therapy (ART) at 3 dpi prevented brain reservoir seeding and normalized metabolic function, highlighting the necessity of very early treatment to protect the developing CNS.

Are we hallucinating or can psychedelic drugs modulate the immune system to control inflammation?

British Journal of Pharmacology, EarlyView.
Psychedelic drugs that activate 5‐HT2A receptors have been long used for cultural, medicinal and recreational purposes. Interest in psychedelics for treating psychiatric disorders has resurged recently and is well documented; less well recognised are their anti‐inflammatory properties. Growing evidence now demonstrates that psychedelics modulate immune

Diaphragm‐specific effects of L‐citrulline in mdx mice highlight its potential as adjuvant of standard therapy in Duchenne muscular dystrophy

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose The absence of the protein dystrophin in Duchenne muscular dystrophy (DMD) leads to progressive muscle weakness, failing regeneration and deregulation of nitric oxide (NO) signalling. We focused on L‐citrulline, a precursor of L‐arginine, required for NO production in muscle, which is reduced in dystrophic mdx muscle ...

Inhibition of Ornithine Decarboxylase 1 Mitigates Denervation‐Induced Muscle Atrophy by Suppressing Proteolysis and Preserving Muscle Stem Cell Homeostasis

Cell Proliferation, EarlyView.
Polyamine metabolism is innervation responsive and involved in denervation‐induced muscle atrophy. Inhibition of polyamine metabolism attenuates muscle atrophy by restraining proteolysis and preserving MuSCs homeostasis. Denervation‐induced activation of FAP‐derived FGF7 drives premature MuSCs activation, while DFMO suppresses this paracrine cue to ...

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

The FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Short‐Term Clinical Effects After Switching From Zinc Acetate Hydrate to Zinc Histidine Hydrate in Patients With Chronic Liver Disease

Hepatology Research, EarlyView.
Zinc deficiency is frequently seen in patients with chronic liver disease and is linked to poor appetite and nutritional status. We found that switching to zinc histidine hydrate increased zinc levels within a short period and was associated with improved appetite.

Physicochemical Quality and Chemical Safety of Commercial Wet Cat Food: Composition, Oxidation, Biogenic Amines, and Trace Elements

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study investigated the physicochemical characteristics and chemical safety of commercial wet cat foods marketed in Brazil. Twenty products labeled as beef, chicken and fish flavors were analyzed for proximate composition, pH, lipid and protein oxidation, biogenic amines, and essential and potentially toxic trace elements.

Epigenetic Regulation in the Pathogenesis of Periodontitis

Journal 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.

The Oral‐Gut Axis: Bidirectional Interactions Between Microbiome and Diseases

Journal of Periodontal Research, EarlyView.
This study aims to summarize the mechanisms underlying ectopic colonization of the gut by oral pathobionts and the microbial and host factors that regulate this process. ABSTRACT Increased colonization of typically oral microorganisms is frequently observed in the gut mucosa or lumen of individuals with gastrointestinal disorders, including patients ...
