A systematic review on current approaches in bat virus discovered between 2018 and 2022.

Zoonotic viruses are widely seen as the primary threat for future pandemics. Bats are the most diverse group of mammals, with more than 1400 species distributed across most habitats on Earth. So far, 31 known virus families were associated with bats, although the understanding of most viruses were insufficient.

Phosphorylation of interferon regulatory factor 9 (IRF9).

Background: IRF9 is a transcription factor that mediates the expression of interferon-stimulated genes (ISGs) through the Janus kinase-Signal transducer and activator of transcription (JAK-STAT) pathway. The JAK-STAT pathway is regulated through phosphorylation reactions, in which all components of the pathway are known to be phosphorylated except IRF9. The enigma surrounding IRF9 regulation by a phosphorylation event is intriguing.

The Role of the Z-DNA Binding Domain in Innate Immunity and Stress Granules.

Both DNA and RNA can maintain left-handed double helical Z-conformation under physiological condition, but only when stabilized by Z-DNA binding domain (ZDBD). After initial discovery in RNA editing enzyme ADAR1, ZDBD has also been described in pathogen-sensing proteins ZBP1 and PKZ in host, as well as virulence proteins E3L and ORF112 in viruses. The host-virus antagonism immediately highlights the importance of ZDBD in antiviral innate immunity.

Rapid detection of porcine DNA in processed food samples using a streamlined DNA extraction method combined with the SYBR Green real-time PCR assay.

A specialized DNA extraction method and a SYBR Green quantitative polymerase chain reaction (SyG-qPCR) assay were combined to generate a ready-to-use kit for rapid detection of porcine admixtures in processed meat products. Our qPCR assay utilized repetitive LINE-1 elements specific to the genome of Sus scrofa domesticus (pig) as a target and incorporated internal controls. We improved the genomic DNA extraction method, and reduced extraction times to the minimum.

Acute ingestion of hydrogen-rich water does not improve incremental treadmill running performance in endurance-trained athletes.

There is emerging evidence that hydrogen-rich water (H-water) has beneficial effects on the physiological responses to exercise. However, few studies investigate its ergogenic potential. This randomized controlled trial examined the effects of H-water ingestion on physiological responses and exercise performance during incremental treadmill running.

Interferon Regulatory Factor 9 Structure and Regulation.

Interferon regulatory factor 9 (IRF9) is an integral transcription factor in mediating the type I interferon antiviral response, as part of the interferon-stimulated gene factor 3. However, the role of IRF9 in many important non-communicable diseases has just begun to emerge. The duality of IRF9's role in conferring protection but at the same time exacerbates diseases is certainly puzzling.

Proteins that contain a functional Z-DNA-binding domain localize to cytoplasmic stress granules.

Long double-stranded RNA may undergo hyper-editing by adenosine deaminases that act on RNA (ADARs), where up to 50% of adenosine residues may be converted to inosine. However, although numerous RNAs may undergo hyper-editing, the role for inosine-containing hyper-edited double-stranded RNA in cells is poorly understood. Nevertheless, editing plays a critical role in mammalian cells, as highlighted by the analysis of ADAR-null mutants.
