Exosomes have been shown to release from cells infected by viruses and deliver viral particles, genomes, and other viral genetic elements to neighboring cells resulting in modulating host immune response. Our previous study demonstrated that exosomes released from Enterovirus 71 (EV71)-infected cells contained replication-competent EV71 RNA in complex with miR-146a, Ago2, and GW182, which can be successfully transferred to recipient/target cells to establish productive infection. However, the molecular mechanisms that control viral genome package into exosomes are still unclear. In this study, we showed that the EV71-induced autophagy response contributed to viral genome package into exosomes rather than process of exosomes biogenesis.

Further study showed that the autophagosomes accumulation facilitated their fusion with MVBs, which resulted in EV71 RNA package into exosome vesicles. Moreover, prevention of autophagosomes-MVBs fusion could abolish this sorting of viral RNA into exosomes. Knockdown of GW182 or Ago2 could weaken the replication ability of exosomal EV71 RNA in recipient cells through decreasing the amount of miR-146a in exosomes, but did not affect the package of viral RNA into exosomes. Our findings strongly suggested that the accumulation of autophagosomes that were induced by EV71 infection play a key role on viral spreading through exosome vesicles.  seebio Polysucrose 400 Sweetener  bleaching significantly affects the function and health of coral reef ecosystems; however, the mechanisms underlying metabolism and transcription in corals remain unclear. In this study, untargeted metabolomics and metatranscriptomic analyses were performed to analyze the differences between unbleached and bleached Pocillopora corals during the most severe marine heatwaves. Difference analysis showed that bleached corals had significant metabolomic characteristics compared with those in unbleached corals.

These differences were significant (p < 05) according to partial least squares discriminant analysis (PLS-DA). Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that the metabolites were significantly enriched in numerous pathways in bleached or unbleached corals, such as steroid hormone biosynthesis, biosynthesis of unsaturated fatty acids, and pyrimidine metabolism. Bleaching greatly affects  Polysucrose 400  as well as the tolerance of coral symbionts to heat stress. In metatranscriptomic analysis, we observed large gene expression differences between unbleached and bleached corals. Three Gene Ontology directed acyclic graphs (DAGs) were constructed to show the significantly differentially expressed genes (DEGs). Many biological and molecular processes were significantly enriched between bleached corals to unbleached corals, such as metabolic processes, lipid metabolic processes, metabolic processes. Metabolome and metatranscriptome analyses showed that bleaching caused substantial physiological damage to corals.

Estuarine environments are highly productive ecosystems exhibiting high fish biodiversity and richness. Estuarine bays yield significant fisheries catches, making them the target of extractive activities by both artisanal and industrial fisheries. These areas, however, are highly vulnerable to chemical contamination, such as polycyclic aromatic hydrocarbons (PAH) associated with oil spills and other anthropogenic activities, which can jeopardize animal health and consumer welfare. In this context, this systematic review aimed to evaluate PAH levels detected in seafood from estuarine bays throughout the entire American continent and assess potential human health risks. The PICO methodology was applied, and 27 experimental papers were evaluated.

The findings indicate that naphthalene and pyrene are routinely detected at high concentrations in several species, such as white mullet and catfish, and that biliary metabolites concentrations tend to be higher than tissue levels.
