RNA-Directed DNA Methylation Systems in Plants and Animals Reveal Ancestral and Convergent Features

Scientists in the United States have identified a clade of catalytically mutated DRM2 paralogs in flowering plant genomes, which they term DOMAINS REARRANGED METHYLTRANSFERASE3 (DRM3). Despite being catalytically mutated, DRM3 is required for normal maintenance of non-CG DNA methylation, establishment of RNA-directed DNA methylation triggered by repeat sequences, and accumulation

Potential Application of Mesenchymal Stem Cells in Acute Lung Injury

Scientists have been struggling to develop effective treatment options for acute lung injury, a condition with a mortality rate of approximately 40%. Despite extensive research into the pathogenesis of acute lung injury and the acute respiratory distress syndrome, current treatment is primarily supportive. Innovative therapies are needed, and recent studies

Differential Cellular Responses to Protein Adducts of Naphthoquinone and Monocrotaline Pyrrole

A recent study in the United States has explored the effects of protein-xenobiotic adducts on human pulmonary artery endothelial cells. Investigators treated cells with naphthoquinone and monocrotaline pyrrole, two pneumotoxic electrophiles that form covalent adducts with proteins rich in reactive thiols. The results suggest that electrophile adduction to a specific

Recrudescence of Latent Equine Herpesvirus 1 (EHV-1) in Horses after Corticosteroid Administration

Scientists in the United States have investigated the reactivation of latent EHV-1 in horses after administration of corticosteroids. This study aimed to describe the viral kinetics of reactivated EHV-1 in blood and nasal secretions from latently infected horses and to study the infectious nature of reactivated EHV-1 to sentinel horses.
