Trypanosoma brucei brucei
Protein synthesis in Trypanosoma brucei brucei was rapidly inhibited during polyamine depletion by DL-adifluoromethylornithine (DFMO) in vitro and in vivo. [3H]Leucine incorporation was depressed 30-40 % by 24 h and 80-90 % by 48 h of DFMO treatment. Concomitantly there was an apparent decrease in the synthesis of the variant-specific glycoprotein (VSG) in DFMO-treated trypanosomes, as measured...
متن کاملGlobal metabolic responses of mice to Trypanosoma brucei brucei infection.
Human African trypanosomiasis (HAT) is transmitted by tsetse flies and, if untreated, is fatal. Treatment depends on infection stage, and early diagnosis is crucial for effective disease management. The systemic host biochemical changes induced by HAT that enable biomarker discovery or relate to therapeutic outcome are largely unknown. We have characterized the multivariate temporal responses o...
متن کاملProtein isoprenylation in Trypanosoma brucei brucei.
Trypanosoma brucei is a digenetic protozoan parasite presenting a public health hazard in certain areas of Africa; it is transmitted between mammals (bloodstream form (BSF)) by tsetse flies (procyclic form (PCF)). We have an ongoing interest in small GTP proteins in T. brucei, and these are commonly isoprenylated. Many isoprenylated proteins belong to the rab family and include ras; the isopren...
متن کاملIn vitro growth inhibition of bloodstream forms of Trypanosoma brucei and Trypanosoma congolense by iron chelators
African trypanosomes exert significant morbidity and mortality in man and livestock. Only a few drugs are available for the treatment of trypanosome infections and therefore, the development of new anti-trypanosomal agents is required. Previously it has been shown that bloodstream-form trypanosomes are sensitive to the iron chelator deferoxamine. In this study the effect of 13 iron chelators on...
متن کاملSUMOylation in Trypanosoma brucei
Small ubiquitin like modifier (SUMO) proteins are involved in many processes in eukaryotes. We here show that Trypanosoma brucei SUMO (Tb927.5.3210) modifies many proteins. The levels of SUMOylation were unaffected by temperature changes but were increased by severe oxidative stress. We obtained evidence that trypanosome homologues of the SUMO conjugating enzyme Ubc9 (Tb927.2.2460) and the SUMO...
