Project description:We sought to determine the effect of TbPARN-1 overexpression on global mRNA steady-state levels in T. brucei. The mRNA expression profile of tet-induced TbPARN-1 OvEx procyclic cells was compared to the mRNA profile of control cells (expressing tet-induced TAP tag alone) by microarray analysis. Since overexpression of TbPARN-1 showed increased deadenylation activity in cytoplasmic extracts, overexpressing PARN-1 in vivo should result in more rapid deadenylation and decay of mRNAs targeted by PARN-1. Thus, mRNAs with lower steady state levels in PARN-1 OvEx cells can be considered likely targets for PARN-1-dependent deadenylation.
Project description:A procyclic form Trypansome brucei RNAi line (PTT parental line, transfected with pALC14 incorporating a TbNMD3 gene fragment) capable of inducing depletion of TbNMD3 was analysed for mRNA expression by RNAseq
Project description:Cy3 and Cy5 direct labelled RNA from Bloodstream MiTat1.1 trypanosomes and Procyclic 427 Lister were hybridized onto JCVI Trypanosoma brucei oligoarrays (version2). Procyclic RNA were used as control for data analysis.
Project description:Trypanosoma brucei gambiense is the causative agent of the fatal human disease African sleeping sickness. Here we have compared the transcriptome of two different life cycle stages, the potentially human-infective bloodstream form and the non-human-infective procyclic stage, using digital gene expression (DGE) analysis.
Project description:Surface-exposed proteins of the bloodstream and procyclic forms of T. brucei were biotinylated, affinity purified using streptavidin, and analyzed by LC-MS/MS
