No. of bitstreams: 0 Previous issue date: 2021-01-01; Athenaea velutina is a promising Brazilian shrub with cytotoxic and antimigratory properties against cancer cells. However, the mechanism of induction of cancer cell death and the compounds involved remain unknown. To ascertain these bioactive compounds, bioassay-guided fractionation was performed, alon...

Porcine circovirus-2 (PCV2) is the etiologic agent of several diseases in pigs, including multi-systemic wasting syndrome (PMWS). In this work, a new mutant PCV2b was isolated from PMWS-affected pigs on a Brazilian farm. Its genome showed high sequence similarity (>99 % identity) to those from a group of emerging mutants isolated from cases of PMWS outbreaks in vaccinated pigs in China, the USA and South Korea....
Ki-1/57 (HABP4) and CGI-55 (SERBP1) are regulatory proteins and paralogs with 40.7% amino acid sequence identity and 67.4% similarity. Functionally, they have been implicated in the regulation of gene expression on both the transcriptional and mRNA metabolism levels. A link with tumorigenesis is suggested, since both paralogs show altered expression levels in tumor cells and the Ki-1/57 gene is found in a regio...
Three porcine circovirus-2 strains were isolated from pigs on a Brazilian farm during an outbreak, indicating a vaccine failure. They present identical genomic sequences, with high identities to other isolates that were also related to vaccination failures, supporting the recent theory about an antigen drift being associated with vaccine failures throughout the world.
