Competing roles of coevolution, selective pressure and recombination are an emerging interest in virus evolution. We report a novel aviadenovirus from captive red-bellied parrots (Poicephalus rufiventris) that uncovers evidence of deep recombination among aviadenoviruses. The sequence identity of the virus was most closely related to Turkey adenovirus D (42% similarity) and other adenoviruses in chickens, turkeys and pigeons. Sequencing and comparative analysis showed that the genome comprised 40,930 nucleotides containing 42 predicted open reading frames (ORFs) 19 of which had strong similarity with genes from other adenovirus species. The new genome unveiled a lineage that likely participated in deep recombination events across the genus Aviadenovirus accounting for an ancient evolutionary relationship. We hypothesize frequent host switch events and recombination among adenovirus progenitors in Galloanserae hosts caused the radiation of extant aviadenoviruses and the newly assembled Poicephalus adenovirus genome points to a potentially broader host range of these viruses among birds.

Sulfation plays a critical role in the biosynthesis of small molecules, regulatory mechanisms such as hormone signaling, and detoxification processes (phase II enzymes). The sulfation reaction is catalyzed by a broad family of enzymes known as sulfotransferases (SULTs), which have been extensively studied in animals due to their medical importance, but also in plant key processes. Despite the identification of some sulfated metabolites in fungi, the mechanisms underlying fungal sulfation remain largely unknown.

This study aims to investigate the clinical characterization and molecular pathogenic basis of hereditary protein C (PC) deficiency in two independent Chinese families, and conduct in vitro expression studies on the newly discovered p.Trp444Arg mutation. The PC activity (PC: A) was tested using the chromogenic substrate, and PC antigen (PC: Ag) was detected via enzyme-linked immunosorbent assay (ELISA).

Uterine leiomyosarcoma (uLMS) is a rare and aggressive cancer representing approximately 25 % of all uterine malignancies. The molecular heterogeneity and pathogenesis of uLMS are not well understood, and translational studies aimed at discovering the vulnerabilities of this tumor type are of high priority. We conducted an innovative comprehensive multi-omics integration study from DNA to protein using freshly frozen tumors.

There is strong interest in accurate methods for predicting changes in protein stability resulting from amino acid mutations to the protein sequence. Recombinant proteins must often be stabilized to be used as therapeutics or reagents, and destabilizing mutations are implicated in a variety of diseases. Due to increased data availability and improved modeling techniques, recent studies have shown advancements in predicting changes in protein stability when a single-point mutation is made.
