Plasmodium vivax is the most widespread parasite causing malaria, being
especially prevalent in the Americas and Southeast Asia. Children are one of the
most affected populations, especially in highly endemic areas. However, there are
few studies evaluating the therapeutic response of infants with vivax malaria.
This study retrospectively evaluated the parasitaemia clearance in children
diagnosed with vivax malaria during the first five days of exclusive treatment
with chloroquine (CQ). Infants aged less than six months old had a significantly
slower parasitaemia clearance time compared to the group of infants and children
between six months and 12 years old (Kaplan-Meier survival analysis; Wilcoxon
test; p = 0.004). The impaired clearance of parasitaemia in younger children with
vivax malaria is shown for the first time in Latin America. It is speculated that
CQ pharmacokinetics in young children with vivax malaria is distinct, but this
specific population may also allow the detection of CQ-resistant parasites during
follow-up, due to the lack of previous immunity. 相似文献

The study of conserved protein interaction networks seeks to better understand the evolution and regulation of protein interactions. Here, we present a quantitative proteomic analysis of 18 orthologous baits from three distinct chromatin‐remodeling complexes in Saccharomyces cerevisiae and Homo sapiens. We demonstrate that abundance levels of orthologous proteins correlate strongly between the two organisms and both networks have highly similar topologies. We therefore used the protein abundances in one species to cross‐predict missing protein abundance levels in the other species. Lastly, we identified a novel conserved low‐abundance subnetwork further demonstrating the value of quantitative analysis of networks. 相似文献

Phosphatase and tensin homolog (PTEN), deleted on chromosome 10, is a potent tumor suppressor. PTEN expression is reduced in advanced bladder cancer and reduction correlates with disease stage. To gain insights into the function of PTEN in human bladder cancer by identifying its binding partners, we developed a novel IPTG inducible PTEN expression system and evaluated this system in the PTEN null UMUC-3 human bladder cancer xenograft model. In this model, induction of PTEN in vivo resulted in reduced tumor growth. We used mass spectrometry to identify PTEN interaction partners in these cells, which identified known interaction partners major vault protein (MVP) and paxillin as well as a novel interaction partner, TRK fused gene (TFG). In conclusion, using a biologically relevant model system to dissect PTEN tumor suppressor function in human bladder cancer, we identified three molecules important for many cellular functions in complex with PTEN. 相似文献
