DNA sequencing of human nontransformed retinal pigment epithelia RPE-PPM1D-T2 cells carrying a truncating mutation in exon 6 of the PPM1D

ABSTRACT: Human nontransformed retinal pigment epithelia RPE-PPM1D-T2 cells carrying a truncating mutation in exon 6 of the PPM1D were exposed to ionising radiation (3 Gy) and subsequently were grown in semisolid media for 8 weeks. Six spheroid clones (RPE-PPM1D-T2-SA clones 1-6) were recovered and then were cultivated in adherent conditions. DNA was isolated from asynchronically growing parental RPE-PPM1D-T2 and transformed RPE-PPM1D-T2-SA-1 to 6 cells and was subjected to whole exome sequencing. DNA sequencing libraries were prepared using KAPA EvoPlus Kit (Roche) and were sequenced on the NovaSeq 6000 system using NovaSeq S1 Reagent Kit v1.5, 200 cycles (Illumina) with mean coverage >35 DNA samples, respectively. DNA fastq files were mapped to the hg19 reference using Novoalign (novoalign_2.08.03). PCR duplicates were removed from the BAM files using Picard Tools (picard-tools 1.129), and variant calling was performed using GATK HaplotypeCaller (3.8). Copy number variations (CNV) were analyzed using CNVkit version 0.7.4. Areas with median coverage >20 were included in the analysis. RNA fastq files were mapped to the hg19 reference using STAR (STAR-2.5.2b). The PCR duplicates were removed using Picard Tools (picard-tools 1.129).

RNA sequencing of human nontransformed retinal pigment epithelia RPE-PPM1D-T2 cells carrying a truncating mutation in exon 6 of the PPM1D – CLONE 0 AND CLONE 1

Project description:Human nontransformed retinal pigment epithelia RPE-PPM1D-T2 cells carrying a truncating mutation in exon 6 of the PPM1D were exposed to ionising radiation (3 Gy) and subsequently were grown in semisolid media for 8 weeks. Six spheroid clones (RPE-PPM1D-T2-SA clones 1-6) were recovered and then were cultivated in adherent conditions. RNA was isolated from asynchronically growing parental RPE-PPM1D-T2 and transformed RPE-PPM1D-T2-SA-1 to 6 cells and was subjected to whole exome sequencing. RNA sequencing libraries were prepared using KAPA RNA HyperPrep Kit (Roche) and were sequenced on the NovaSeq 6000 system using NovaSeq S1 Reagent Kit v1.5, 200 cycles (Illumina) with mean coverage >120 for RNA samples, respectively. RNA fastq files were mapped to the hg19 reference using Novoalign (novoalign_2.08.03). PCR duplicates were removed from the BAM files using Picard Tools (picard-tools 1.129), and variant calling was performed using GATK HaplotypeCaller (3.8). RNA fastq files were mapped to the hg19 reference using STAR (STAR-2.5.2b). The PCR duplicates were removed using Picard Tools (picard-tools 1.129). All parts of RNAseq data analysis were conducted in R, version 4.3.2. and RNAseq read counts were normalized using R package DESeq2. Fold change (FC) and log2FC were calculated from normalized reads, nontransformed RPE-PPM1D-T1 cells were considered a reference. Significance of differential expression for each gene was evaluated by Fisher's t-test with simulated p-values and Holm's p-value correction for multiple comparisons.

Exome sequencing in classic Hairy cell leukaemia reveals widespread variation in acquired somatic mutations between individual tumours apart from the signature BRAF V(600)E lesion

Project description:Whole exome sequencing of 5 HCLc tumor-germline pairs. Genomic DNA from HCLc tumor cells and T-cells for germline was used. Whole exome enrichment was performed with either Agilent SureSelect (50Mb, samples S3G/T, S5G/T, S9G/T) or Roche Nimblegen (44.1Mb, samples S4G/T and S6G/T). The resulting exome libraries were sequenced on the Illumina HiSeq platform with paired-end 100bp reads to an average depth of 120-134x. Bam files were generated using NovoalignMPI (v3.0) to align the raw fastq files to the reference genome sequence (hg19) and picard tools (v1.34) to flag duplicate reads (optical or pcr), unmapped reads, reads mapping to more than one location, and reads failing vendor QC.

Transcriptional profiling of activated CD4+ memory T cells exposed to anti-TNF and recombinant human TNF-alpha in vitro

Project description:We performed an RNA-seq analysis on FACS-sorted CD4+ memory T cells (Tmem, CD4+CD25-CD45RA-) stimulated in vitro with anti-CD3/CD28 coated beads (1:5), IL-2 (100 U/mL) in the presence of a TNF-alpha inhibitor (Etanercept, ETN, 5 Î¼g/mL) or recombinant human TNF-alpha (rhTNF-alpha, 50 ng/mL) treatment. The cells were cultured for three days at 37Â°C and 5% CO2. On day three Tmem were lysed (Buffer RLT supplemented with DTT, QIAGEN) and RNA extraction was performed (RNeasy Plus Micro kit), followed by sample preparation with TruSeq (polyA) mRNA kits (Illumina), RNA sequencing (carried out by an Illumina HiSeq2500), and the alignment of trimmed fastQ files to GRCh38 human reference genome. We also performed a Quality control (QC). This was done using the tool FastQC FastQC/0.11.3-Java-1.7.0_80. QC metrics were calculated for the aligned reads using Picard-tools picard/1.130-Java-1.7.0_80, CollectRnaSeqMetrics, MarkDuplicates, CollectInsertSize-Metrics and SAMtools/1.2-foss-2015b flagstat. Finally, we carried out a Differential expression gene (DEG) analysis using DESeq2, in order to evaluate the impact of ETN and rhTNF-alpha on Transcriptome profiling of stimulated CD4+ Tmem. Principal Component Analysis (PCA) was carried out to visualise the samples given their entire transcriptome and any remaining batch effects.

CpG island mediated linear and spatial gene partitioning (RNA-seq)

Project description:We reanalyzed published RNA-seq data to study 1) the genomic landscapes near surrounding regions of transcriptional start sites with regard to the gene expression activities and 2) the gene expression change upon transcription factor (MYBL1, ATF4) depletion. Raw data were downloaded from Sequence Read Archive (SRA) in National Center for Biotechnology Information (NCBI) database. FASTQ files were extracted with the SRA Toolkit version 2.5.5 and aligned using STAR 2.4.2 onto the mouse and human genome (mm9 and hg19, respectively). Gene expression was calculated as RPKM values using rpkmforgenes.py (Ramsköld et al., 2009).
