Transcription profiling of T. brucei trypanosomes during differentiation reveals the existence of multiple post-transcriptional regulons.

ABSTRACT: We analysed differentiation of the EATRO1125 strain of Trypanosoma brucei brucei, which was first isolated in 1966 from a bushbuck (Tragelaphus scriptus) in Uganda (origin stated (Bouteillea, 1995) without an original reference.
To analyse gene expression, we isolated at least 3 x 10e8 trypanosomes at different differentiation states, using two independent biological replicates. Bloodstream forms were harvested at a density of 2 x 10e5/ml (low density, logarithmic growth), and 2 x 10e6/ml (high density, logarithmic growth). Cells were also taken immediately upon attaining the density of 2 x 106/ml, treated with 3 mM cis-aconitate and moved to a room at 27M-0C. Samples were taken 30 min, 60 min, 12h and 24h after this. At 24 h the cells were centrifuged, resuspended (at 27M-0C) in MEM-Pros medium, which contains proline as the major energy source. Samples were taken again at 48h and 72h. A culture that had been maintained for several weeks after transformation was used as a source of established procyclic trypanosomes.
