ATAC-seq data in MEF and mESC sequenced by BGI DNBSEQ-G400 platform and Illumina HiseqX10 instruments

ABSTRACT: We benchmark Illumina’s HiseqX10 instrument against Beijing Genomics Institute’s (BGI) DNBSEQ-G400 platform, a considerably cheaper sequencing alternative. For comparisons, the same bulk ATAC-seq libraries generated from pluripotent stem cells (PSCs) and fibroblasts were sequenced on both platforms. Both instruments generate sequencing reads with comparable mapping rates and genomic context. However DNBSEQ-G400 data contained a significantly higher number of small, sub-nucleosomal reads (>30% increase) and a reduced number of bi-nucleosomal reads (>75% decrease), which resulted in narrower peak-bases and improved peak calling, enabling the identification of 4% more differentially accessible regions between PSCs and fibroblasts. Ability to identify master TFs that underpin the PSC state relative to fibroblasts, including aggregate and de novo foot-printing capacity, were highly similar between data generated on both platforms.

Allele-resolved scRNA-seq of primary mouse fibroblasts using Smart-seq3

Project description:Allele-sensitive RNA sequencing of single-cells can be used to infer the kinetics of transcriptional bursts in eukaryotic cells. Here, we used the Smart-seq3 protocol to prepare libraries from two 384-well plates of primary mouse fibroblasts. The fibroblasts were derived from tail explants of a male adult mouse (F1 offspring of C57 x CAST cross). The samples were sequenced to high depth using MGI's DNBSEQ G400RS platform using paired-end 100 bp reads.

Gene expression of Dcir-/- dendritic cells (DCs) after antigen stimuulation

Project description:Purpose: DCIR is an inhibitory type of C-type lectin receptor that regulates DC functions. This study aimed to find the genes that could be regulated through DCIR. Method: Splenic DCs from WT and Dcir-/- mice were colutured with T cells that express specific TCR for MOG35-55 for 3 days in the presence of MOG peptide. CD11c+ cells were collected by an auto MACS. RNA profiles were generated by deep sequencing, in triplicate, using DNBSEQ-G400. Results: We detected xxx gense that were higher expression in Dcir-/- DCs, compared with WT DCs, with a fold change ≥1.5 and p value <0.05. Conclusion: Our data showed that Dcir deficiency in DCs changed the gene expression pattern, compared to WT DCs, in the coculture system of T cells. DCIR regulates the expression of DC genes that are associated with the functions of DCs.

Assessing the Accuracy of Seismofit as an Estimate of VO2 Peak in Patients With Hepato-pancreato-biliary, Colorectal, and Gastro-oesophageal Cancer

Project description:Our study aims to assess the relationship between the Seismofit derived VO2 peak estimate and CPET-measured VO2 peak in patients who are having CPET as part of their preoperative workup. Our aim is to establish whether Seismofit can be considered a cheaper, less resource intensive and better tolerated alternative to the CPET, or whether it might be useful as a screening tool to efficiently identify patients with exercise intolerance who may benefit from further characterisation by CPET.

Gene expression profiling of human whole-blood samples before and after the administration of recombinant human erythropoietin

Project description:As part of cross-platform comparisons of microarray and RNA-seq, this current experiment using the Affymetrix Human Transcriptome Array 2.0 aimed to quantify gene-level expression in subjects administered recombinant human erythropoietin over a 10-week protocol for the identification of gene signatures of blood doping. These results were compared to results obtained from other gene expression quantification platforms using the same experimental cohort, including the Illumina HumanHT-12v4 Expression BeadChips (archived in ArrayExpression; E-MTAB-2874), Illumina NextSeq 500 and MGI DNBSEQ-G400RS.

Transcriptional changes caused by ablation of neuropeptide FF receptor-1 (NPFFR1)

Project description:We compared inguinal fat depots of wild-type (WT) and NPFFR1 deficient (NPFFR1-KO) mice at postnatal day 6. In this project, we sequence 6 samples used DNBseq platform, averagely generating about 32.03 M reads per sample. The average mapping ratio with reference genome is 95.49%, the average mapping ratio with gene is 73.18%; A total of 19,886 genes were detected.

Gene expression profile at single cell level of mesenchymal cells and cancer-associated fibroblasts from mouse pancreas

Project description:Pancreatic stellate cells (PSCs) are components of normal pancreatic mesenchyme, and give rise to cancer-associated fibroblasts during pancreatic tumorigenesis. We used single cell RNA sequencing (scRNA-seq) to analyze PSCs and PSC-derived CAFs from normal pancreas and pancreatic cancer tissues, respectively.
