Raman Analysis of RNA Nucleotide Strands From SARS‐CoV‐2 Variants and Subvariants: A Step Forward in the Definition of “Raman Genome”

Advanced Science, EarlyView.
Main Raman signals in RNA, related to helical backbone, ribofuranose ring, and nitrogenous bases, are affected by secondary structures that cause hyperchromic effects and significantly alter the Raman intensity. ABSTRACT Raman spectra of RNA nucleotide strands extracted from 20 SARS‐CoV‐2 strains, including the original Japanese isolate, Alpha, Beta ...

Coronavirus immunogens

Veterinary Microbiology, 1993
Coronaviruses (CV) infect a variety of livestock, poultry and companion animals. They belong to at least five antigenic groups. CV cause localized infections of the respiratory and/or intestinal tracts, with the exception of feline infectious peritonitis virus (FIPV) and hemagglutinating encephalomyelitis (HEV) which cause systemic infections.

An ATP‐Driven N Protein–DDX21 Molecular Switch Dynamically Controls SARS‐CoV‐2 RNA G‐Quadruplex Heterogeneity

Advanced Science, EarlyView.
An ATP‐driven molecular switch, comprising viral nucleocapsid (N) protein and host helicase DDX21, dynamically modulates SARS‐CoV‐2 RNA G‐quadruplex (G4) heterogeneity. These viral G4s feature non‐canonical ion‐dependence and act as energy‐sensitive structural checkpoints.

A coronavirus detected in the vampire bat Desmodus rotundus

Brazilian Journal of Infectious Diseases
This article reports on the identification of a group 2 coronavirus (BatCoV DR/2007) in a Desmodus rotundus vampire bat in Brazil. Phylogenetic analysis of ORF1b revealed that BatCoV DR/2007 originates from a unique lineage in the archetypical group 2 ...

An Oral Antiviral Combination Against Severe COVID‐19 Enabled by the Synergistic Mechanisms of Action of Auranofin and Remdesivir

Advanced Science, EarlyView.
FDA‐approved anti‐inflammatory drug Auranofin inhibits SARS‐CoV‐2 replication by inhibiting viral Main protease activity and Spike processing required for viral entry. It shows strong synergy with nucleoside analogue Remdesivir, due to non‐overlapping mechanisms.

Gapless Complete Genome and Multi‐Omics Illuminate Immune Adaptation and Host‐Virus Interactions in a Coronavirus Reservoir

Advanced Science, EarlyView.
We present a complete T2T genome assembly for a key bat reservoir. Integrating population genomics, comparative genomics, transcriptomics, single‐cell omics, and functional assays, we resolve previously inaccessible genomic regions and identify evolutionary signatures associated with immune adaptation.

CircFAM65A/CANX Condensates Sequester FAM134B to Inhibit ER‐phagy and Suppress Hepatocellular Carcinoma Progression

Advanced Science, EarlyView.
The novel circRNA circFAM65A suppresses HCC progression. Mechanistically, circFAM65A drives CANX phase separation, which recruits FAM134B into condensates and blocks its interaction with LC3, thereby inhibiting ER‐phagy and HCC progression. Importantly, targeted circFAM65A delivery represents a potential therapeutic strategy for HCC.
