Trypanosoma brucei undergoes major biochemical and morphological changes during its development from the bloodstream form in the mammalian host to the procyclic form in the midgut of its insect host. The underlying regulation of gene expression, however, is poorly understood. More than 60% of the predicted genes remain annotated as hypothetical, and the 5' and 3' untranslated regions important for regulation of gene expression are unknown for >90% of the genes. In this review, we compare the data from four recently published high-throughput RNA sequencing studies in light of the different experimental setups and discuss how these data can enhance genome annotation and give insights into the regulation of gene expression in T. brucei.

UI MeSH Term Description Entries
D005786 Gene Expression Regulation Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control (induction or repression) of gene action at the level of transcription or translation. Gene Action Regulation,Regulation of Gene Expression,Expression Regulation, Gene,Regulation, Gene Action,Regulation, Gene Expression
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D012326 RNA Splicing The ultimate exclusion of nonsense sequences or intervening sequences (introns) before the final RNA transcript is sent to the cytoplasm. RNA, Messenger, Splicing,Splicing, RNA,RNA Splicings,Splicings, RNA
D014158 Transcription, Genetic The biosynthesis of RNA carried out on a template of DNA. The biosynthesis of DNA from an RNA template is called REVERSE TRANSCRIPTION. Genetic Transcription
D014346 Trypanosoma brucei brucei A hemoflagellate subspecies of parasitic protozoa that causes nagana in domestic and game animals in Africa. It apparently does not infect humans. It is transmitted by bites of tsetse flies (Glossina).
