Analyses included inflammatory cytokines, myeloperoxidase (MPO) activity, and OS markers, such as superoxide dismutase (SOD), catalase (CAT), glutathione <i>S</i>-transferase (GST), gamma-glutamyl transferase (GGT), reduced glutathione (GSH), uric acid (UA), thiobarbituric acid reactive substances (TBARS), and protein carbonyls (PC). Individuals with PASC showed increased IL-6 and IL-8. Both COVID-19 groups exhibited decreased SOD and CAT. GST decreased only in the acute group. Elevated GGT and GSH were found in the PASC group. High UA levels were observed in PASC individuals. There were no changes in TBARS values ⁣⁣in the PASC group. However, PC concentrations were elevated only in this group. Correlations were identified between inflammatory markers and OS parameters. These findings suggest that individuals with PASC pronounced OS, which potentially exacerbates disease complications.

In this study, we examined the genome-wide functions of Prp16 in the short intron-rich genome of the basidiomycete yeast <i>Cryptococcus neoformans</i>. The presence of multiple introns per transcript with intronic features that are more similar to those of higher eukaryotes makes it a promising model for studying spliceosomal splicing. Using a promoter-shutdown conditional Prp16 knockdown strain, we uncovered genome-wide but substrate-specific roles in <i>C. neoformans</i> splicing. The splicing functions of Prp16 are dependent on helicase motifs I and II, which are conserved motifs for helicase activity. A small subset of introns spliced independent of Prp16 activity was investigated to discover that exonic sequences at the 5' splice site (5'SS) and 3' splice site (3'SS) with stronger affinity for U5 loop 1 are a common feature in these introns. Furthermore, short (60-100nts) and ultrashort introns (<60nts) prevalent in the <i>C. neoformans</i> transcriptome were more sensitive to Prp16 knockdown than longer introns, indicating that Prp16 is required for the efficient splicing of short and ultrashort introns. We propose that stronger U5 snRNA-pre-mRNA interactions enable efficient transition of the spliceosome from the first to the second catalytic confirmation in Prp16 knockdown, particularly for short introns and introns with suboptimal features.

IAV PA-X is one of these factors that selectively shuts off the global host genes. However, the specific role of PA-X host shutoff activity in viral fitness of IAV remains poorly understood. Herein, we successfully mapped PA-X 100 V as a novel site important for host shutoff of the H7N9 and H5N1 viruses. By analysing the polymorphism of this residue in various subtype viruses, we found that PA-X 100 was highly variable in H7N9 viruses. Structural analysis revealed that 100 V was generally close to the PA-X endonuclease active site, which may account for its host shutoff activity. By generating the corresponding mutant viruses derived from the parental H7N9 virus and the PA-X-deficient H7N9 virus, we determined that PA-X 100 V significantly enhanced viral fitness in mice while diminishing viral virulence in chickens. Mechanistically, PA-X 100 V significantly increased viral polymerase activity and viral replication in mammalian cells. Furthermore, PA-X 100 V highly blunted the global host response in 293T cells, particularly restraining genes involved in energy metabolism and inflammatory response.
