Project description:Chromatin immunoprecipitation of genomic loci in Trypanosoma brucei where histone variant H4.V is deposited. A previously generated cell line (Siegel et al., 2009) in which both endogenous H4.V alleles are knockout out and ectopic overexpression of a Ty1-tagged version of H4.V can be induced was used. During the ChIP experiment, the DNA was digested with MNase to obtain mononucleosomes. Nucleosomes containing H4.V were pulled down by using a BB2 anti-Ty1 antibody. Cross links are reversed and mononucleosomal DNA is purified and prepared for Illumina sequencing.

Project description:Mitochondrial metabolic remodeling is a hallmark of the Trypanosoma brucei digenetic life cycle since the insect stage utilizes the cost-effective oxidative phosphorylation to generate ATP, while bloodstream cells switch to less energetically efficient aerobic glycolysis. Due to difficulties in acquiring enough parasites from the tsetse fly vector for biochemical analysis, the dynamics of the parasite´s mitochondrial metabolic rewiring in the vector have remained obscure. Here, we took advantage of in vitro-induced differentiation to follow changes at the RNA levels.

Project description:<p>Mitochondrial metabolic remodeling is a hallmark of the Trypanosoma brucei digenetic life cycle since the insect stage utilizes the cost-effective oxidative phosphorylation to generate ATP, while bloodstream cells switch to less energetically efficient aerobic glycolysis. Due to difficulties in acquiring enough parasites from the tsetse fly vector for biochemical analysis, the dynamics of the parasite´s mitochondrial metabolic rewiring in the vector have remained obscure. Here, we took advantage of in vitro-induced differentiation to follow changes at the RNA, protein and metabolite levels. This multi-omics and cell-based profiling showed an immediate redirection of electron flow from the cytochrome mediated pathway to a mitochondrial alternative oxidase, an increase in proline consumption and its oxidation, elevated activity of complex II and certain TCA cycle enzymes, which led to mitochondrial inner membrane hyperpolarization and increased ROS levels in both mitochondrion and cytosol. Interestingly, these ROS molecules acted as signaling molecules driving developmental progression since exogenous expression of catalase, a ROS scavenger, halted the in vitro-induced cell differentiation. Our results provide insights into the mechanisms of the parasite´s mitochondrial rewiring and reinforce the emerging concept that mitochondria act as signaling organelles through release of ROS to drive cellular differentiation.</p><p><br></p><p><strong>Data availability:</strong></p><p><a href='https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?&acc=GSE140796' rel='noopener noreferrer' target='_blank'>RNA-Seq</a></p><p>Proteomic data associated with this study are available in the PRIDE repository: accession number <a href='https://www.ebi.ac.uk/pride/archive/projects/PXD016370' rel='noopener noreferrer' target='_blank'>PXD016370</a>.</p>

Project description:Trypanosomes were sorted (0 cells, 1 cell, 50 cells) using a FACSaria III (BD Biosciences; precision: single-cell; nozzle: 100 µm). Forward-scatter area (FCS-A) versus side-scatter area (SSC-A) was used to gate the cells. Trypanosomes were sorted in 48-wells plate (Brand) filled with 2.6 µL of lysis buffer (0.01 µL of RNAse inhibitor (Takara) and 1x Lysis buffer (Takara) in RNAse-free water). Immediately after sorting cells were placed on ice for 5 minutes and stored at -80 °C. 50 and single trypanosomes were prepared using SMART-Seq v4 Ultra Low Input RNA Kit (Takara) using one fourth of reagents volumes compared to the supplier instructions. PCR amplification was performed using 26 cycles using supplier recommendations. cDNA was purified using XP beads (Beckman Coulter) and recovered in 15 µL of elution buffer (Takara). Libraries were quantified using the Qubit Hs Assay (Life Technologies) and the qualities of the libraries were further monitored using a Bioanalyzer (Agilent). Similar to what has been published previously 19, 1 ng of cDNA was subjected to a tagmentation-based protocol (Nextera XT, Illumina) using one-quarter of the recommended volumes, 10 minuntes for tagmentation at 55 °C and 1 minute extension time during PCR amplification. Libraries were pooled (96 libraries for NextSeq) and sequencing was performed in paired-end mode for 2 × 75 cycles using Illumina's NextSeq 500.
