Trypanosome Prereplication Machinery: A Potential New Target for an Old Problem
Approximately ten million people suffer from Chagas disease worldwide, caused by Trypanosoma cruzi, with the disease burden predominately focused in Latin America. Sleeping sickness is another serious health problem, caused by Trypanosoma brucei, especially in sub-Saharan countries. Unfortunately, the drugs currently available to treat these diseases have toxic effects and are not effective aga...
متن کاملFunctional interplay between a virus and the ESCRT machinery in archaea.
Recently it has been discovered that a number of eukaryotic viruses, including HIV, coopt the cellular Endosomal Sorting Complex Required for Transport (ESCRT) machinery to affect egress from infected cells. Strikingly, the ESCRT apparatus is conserved in a subset of Archaea, including members of the genus Sulfolobus where it plays a role in cytokinesis. In the current work, we reveal that the ...
متن کاملA pre-tRNA carrying intron features typical of Archaea is spliced in yeast.
Archaeal pre-tRNAs are characterized by the presence of the bulge-helix-bulge (BHB) structure in the intron stem-and-loop region. A chimeric pre-tRNA was constructed bearing an intron of the archaeal type and the mature domain of the Saccharomyces cerevisiae suppressor SUP4 tRNA(Tyr). This pre-tRNA(ArchEuka) is correctly cleaved in several cell-free extracts and by purified splicing endonucleas...
متن کاملP-83: Which Novel Sperm Selection Method Is Functional? MACS-DGC or DGC-Zeta
Background: Selection of human spermatozoa prior to assisted reproduction is currently based on motility and morphology. Recently, Zeta method has been introduced for normal sperm selection based on sperm surface charges. In addition, one of the features of apoptosis is the externalization of phosphatidylserine (PS), which are normally present on the inner leaflet of the sperm plasma membrane. ...
متن کاملA unique cell division machinery in the Archaea.
In contrast to the cell division machineries of bacteria, euryarchaea, and eukaryotes, no division components have been identified in the second main archaeal phylum, Crenarchaeota. Here, we demonstrate that a three-gene operon, cdv, in the crenarchaeon Sulfolobus acidocaldarius, forms part of a unique cell division machinery. The operon is induced at the onset of genome segregation and divisio...
