Metabolite profiling on T. brucei exposed to oxidative stress

SysMO is a European transnational funding and research initiative on "Systems Biology of Microorganisms".

The goal pursued by SysMO was to record and describe the dynamic molecular processes going on in unicellular microorganisms in a comprehensive way and to present these processes in the form of computerized mathematical models.

Systems biology will raise biomedical and biotechnological research to a new quality level and contribute markedly to progress in understanding. Pooling European research ...

The SilicoTryp project aims at the creation of a “Silicon Trypanosome”, a comprehensive, experiment-based, multi-scale mathematical model of trypanosome physiology. Trypanosomes are blood-stream parasites transmitted by tsetse flies; they cause African sleeping sickness in humans and livestock. Currently available drugs have severe side effects, and the parasites are rapidly developing resistance. In this project, we collect a wide range of new experimental data on the parasite in its various ...

The aims of this investigation is to quantify metabolites associated with pathways involved in stress responses for parameterising models of oxidative stress metabolism; the measurement of metabolic fluxes of metabolites of interest with intracellular concentrations

In addition to the highly targeted quantification of metabolites already known to play major roles in oxidative stress, to provide data directly compatible with current models, we will also take an untargeted metabolomics approach. This will enable us to identify other areas of the metabolome influenced by, or influencing, oxidative stress and will allow us to compare changes in each of the stress-inducing stimuli. We have recently pioneered untargeted metabolite profiling of T. brucei using ...

Untargeted and targeted metabolic analysis on T. b. brucei 427 grown under oxidative stress with methylene blue has been carried out. This work has been completed with 11 bio-reps and found significant metabolic changes as you can see in the IDEOM file attached. 'Comparison' tab in the data spread sheet shows heat maps and fold change analysis regarding different metabolite levels (T: T brucei, TMB: T. brucei exposed to methylene blue, numbers: time points, 0, 5, 60 & 120min). If you double ...
