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:The first 4 samples belong to the RNA-IP using in situ TAP tagged ZC3H30 in procyclic (insect) form of the parasite T. brucei Lister 427, 2 samples are Elu or eluate, and 2 are FL or flowthrough (unbound) sample. The other 8 samples are also from procyclic cells. 4 samples belong to DKO(ZC3H30 gene double knockout), 2 are non-stressed and 2 are heat shocked samples; the rest 4 samples are DKO-ectopic (ZC3H30 double knockouts, expressing, ectopic copy of ZC3H30) 2 are non-stressed and 2 are heat shocked samples. Heat Shock experiment was done at 39 degree Celsius.
Project description:These are the ribosomal subunit fractions from the polysome gradients. investigating effect of heat shock on procyclic-form trypanosomes.
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
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 Cells were grown for 72 hours in culture; RNAi was induced in cells by the addition of 1 microgram/ml of tetracycline
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:Procyclic trypanosomes (strain 427 lister) were grown in culture under standard conditions at 27ºC in SDM79 medium with 10% foetal bovine serume (Brun and Schnenberger, 1979), in a gazed incubator (5% CO2). Logarithmically growing procyclic cells (at about 5*10^6 cells/ml, at 27°C) were added to one volume medium that had been heated to 53°C and incubated at 41ºC for 60 minutes in a waterbath in a closed tube (41ºC sample). The control cells were added to one volume medium at 27ºC and also incubated for 60 minutes in a closed tube at 27°C. Cells were harvested and washed once in PBS. The harvesting was done within 8 minutes.
