View SamplesObservational studies from low-income countries have shown that the vaccination against diphtheria, tetanus and pertussis (DTP) is associated with excess female mortality due to infectious diseases. To investigate possible changes in gene expression after DTP vaccination, we identified a group of nine comparable West African girls, from a biobank of 356 children, who were due to receive DTP booster vaccine at age 18 months. We extracted RNA from blood samples before, and 6 weeks after, vaccination to analyse the coding transcriptome in leukocytes using expression microarrays, and ended up with information from eight girls. The data was further analysed using dedicated array pathway and network software. We aimed to study whether DTP vaccination introduced a systematic alteration in the immune system in girls. We found very few transcripts to alter systematically. Those that did mainly belonged to the interferon (IFN) signalling pathway. We scrutinized this pathway as well as the interleukin pathways. Two out of eight showed a down-regulated IFN pathway and two showed an up-regulated IFN pathway. The two with down-regulated IFN pathway had also down-regulated IL-6 pathway. In the study of networks, two of the girls stood out as not having the inflammatory response as top altered network. In conclusion, the transcriptome changes following DTP booster vaccination were subtle, but it is possible to identify sub groups that deviate from each other, mainly in the IFN response.

View SamplesTransfer RNA (tRNA) modifications enhance the efficiency, specificity and fidelity of translation in all organisms. The anticodon modification mcm5s2U34 is required for normal growth and stress resistance in yeast; mutants lacking this modification have numerous phenotypes. Mutations in the homologous human genes are linked to neurological disease. The yeast phenotypes can be ameliorated by overexpression of specific tRNAs, suggesting that the modifications are necessary for efficient translation of specific codons. We determined the in vivo ribosome distributions at single codon resolution in yeast strains lacking mcm5s2U. We found accumulations at AAA, CAA, and GAA codons, suggesting that translation is slow when these codons are in the ribosomal A site, but these changes appeared too small to affect protein output. Instead, we observed activation of the GCN4-mediated stress response by a non- canonical pathway. Thus, loss of mcm5s2U causes global effects on gene expression due to perturbation of cellular signaling. Overall design: WT yeast and mutants lacking anticodon tRNA modifications were grown in YPD, and subjected to ribosome footprint profiling (ribo-seq) and RNA-seq of poly-A selected RNA. Dataset contains biological replicates for WT, ?ncs6 and ?uba4. Technical replicates were also performed for all RNA-seq datasets (using a different poly-A selection method).

View SamplesBackground: MYC is a transcription factor encoded by the c-MYC gene (thereafter termed MYC). MYC is key transcription factor involved in many central cellular processes including ribosomal biogenesis. MYC is overexpressed in the majority of human tumours including aggressive B-cell lymphoma especially Burkitt's lymphoma. Although Burkitt's lymphoma is a highlight example for MYC overexpression due to a chromosomal translocation, no global analysis of MYC binding sites by chromatin immunoprecipitation (ChIP) followed by global next generation sequencing (ChIP-Seq) has been conducted so far in Burkitt's lymphoma.

View Samples10 adult participants of dose group 3x10^6 pfu, and 10 participants of dose group 20x10^6 pfu. Reads were aligned to the human reference assembly (GRCh38.p7) using STAR software (v2.4.2a; option ''--quantMode GeneCounts''). Gene annotation was obtained from Ensembl (release 79, ensemble.org). VOOM+Limma analysis (R software, version 3.2.2) was used to assess differential gene expression at each post-vaccination day (d1, d3 and d7) against baseline (d0). Next, we intergreted gene expression data and antibody response using an sPLS algorithm, in order to down-select genes correlating with multivariate antibody responses at days 28, 54, 84,180. Overall design: 56 samples from D0, D1, D3 and D7 were analysed. Data from samples with low RIN (RIN <8, 17 samples), low RNA or library concentration (2 samples), missing samples (5 samples) were set to missing.
