Project description:Three potential ELAV-like proteins of T. brucei, including Tb927.3.2930, Tb927.7.5380, and Tb927.8.6650, were either inhibited by RNAi or phenotypically activated by over-expression, followed by microarray analysis of the transcriptome. The results indicated that these ELAV-like proteins regulate the abundance of a large number of T. brucei transcripts, potentially through regulation of mRNA stability.
Project description:A tagged ectopic version of the ELAV-like protein Tb927.8.6650 of T. brucei was expressed in stable cell lines and pulled down. Co-purifying transcripts were analyzed by sequencing to identify RNAs associated with Tb927.8.6650.

The results indicated that these ELAV-like proteins regulate the abundance of a large number of T. brucei transcripts, potentially through regulation of mRNA stability. Each of the three ELAV-like proteins were either inhibited by RNAi or over-expressed, in stable transgenic procyclic form cell lines. Total RNA was extracted 48h after tetracycline induction of the constructs (except for total RNA from Tb927.8.6650 RNAi which was extracted 24h after tet-induction), and sent to NimbleGen for cDNA synthesis and hybridization. Non-induced cells were analyzed in parallel.
Project description:A tagged ectopic version of the ELAV-like protein Tb927.8.6650 of T. brucei was expressed in stable cell lines and pulled down. Co-purifying transcripts were analyzed by sequencing to identify RNAs associated with Tb927.8.6650. Stable procyclic form cell lines expressing tetracycline-inducible TAP-tagged Tb927.8.6650 were created. Cells were harvested 48h after tet-induction, followed by tandem affinity purification of Tb927.8.6650, extraction of co-purified RNA, and sequencing.
Project description:Trypanosoma brucei gambiense is the causative agent of the fatal human disease African sleeping sickness. Using Digital Gene Expression we have compared the transcriptome of a group 1 T.b.gambiense (Eliane) and a T.b.brucei (STIB 247).
