ArgR regulates motility and virulence through positive control of flagellar genes and inhibition of diguanylate cyclase expression in Aeromonas veronii.

Flagella are essential for biofilm formation, adhesion, virulence, and motility. In this study, the deletion of argR resulted in defects in flagellar synthesis and reduced motility, nevertheless, the underlying mechanism by which ArgR regulated bacterial motility remained unclear. ChIP-Seq and RNA-Seq analysis revealed that ArgR regulated the expression of flagellar genes, concluding two-component system flrBC and multitudinous flagellar structure genes.

Coenzyme Q10 Alleviates Silicosis Fibrosis Inhibiting Ferroptosis in Mice.

Background/aim: Silicosis, the most severe type of occupational pneumoconiosis, leads to diffuse pulmonary fibrosis without specific therapy. Ferroptosis is triggered by reactive oxygen species (ROS) and Fe overload-induced lipid peroxidation, which is involved in the progression of pulmonary fibrosis. As an important coenzyme in the process of aerobic respiration, Coenzyme Q10 (CoQ10) can enhance mitochondrial function and energy supply and reduce malondialdehyde (MDA) to limit the risk of fibrosis.

Alcohol-induced gut microbial reorganization and associated overproduction of phenylacetylglutamine promotes cardiovascular disease.

The mechanism(s) underlying gut microbial metabolite (GMM) contribution towards alcohol-mediated cardiovascular disease (CVD) is unknown. Herein we observe elevation in circulating phenylacetylglutamine (PAGln), a known CVD-associated GMM, in individuals living with alcohol use disorder. In a male murine binge-on-chronic alcohol model, we confirm gut microbial reorganization, elevation in PAGln levels, and the presence of cardiovascular pathophysiology.

An adenosine analog shows high antiviral potency against coronavirus and arenavirus mainly through an unusual base pairing mode.

By targeting the essential viral RNA-dependent RNA polymerase (RdRP), nucleoside analogs (NAs) have exhibited great potential in antiviral therapy for RNA virus-related diseases. However, most ribose-modified NAs do not present broad-spectrum features, likely due to differences in ribose-RdRP interactions across virus families. Here, we show that HNC-1664, an adenosine analog with modifications both in ribose and base, has broad-spectrum antiviral activity against positive-strand coronaviruses and negative-strand arenaviruses.
