Long and short-read transcriptome profiling of human lung cancer cell lines

ABSTRACT: Purpose: The aim of this study is to compare different long-read sequencing platforms using reference lung adenocarcinoma cell lines and spike-in controls. Methods - Cell Culture: Lung adenocarcinoma cell lines NCI-H1975 and HCC827 from a range of passages (2-4) were grown on 3 separate occasions in Roswell Park Memorial Institute (RPMI) 1640 medium with 10% fetal calf serum and 1% penicillin-streptomycin. Methods - RNA preparation: mRNA was extracted using a Qiagen RNA miniprep kit and purified using the NEBNext® Poly(A) mRNA Magnetic Isolation Module (E7490). Purified mRNA spiked with sequins was used for Next Generation Sequencing library preparation using the NEBNext Ultra II Directional RNA Library Prep Kit (Illumina) and the cRNA-PCR Barcoding (SQK-PCS109 with SQK-PBK004) kit (ONT). Completed libraries were sequenced on NextSeq 500 (Illumina) and PromethION (ONT). Iso-Seq libraries were prepared and sequenced by Novogene on Sequel II (PacBio). Reads were mapped to known genomic features of the GRCH38 reference genome and RNA sequin decoy chromosome combined sequences at the gene-level and single reads were then summarized into gene-level counts using featureCounts software (Liao et al. 2014).

Long-read transcriptome profiling of human lung cancer cell lines

Project description:Purpose: The aim of this study is to compare the transcriptome profiles using a mixture design that allows the relative changes of the majority of the genes profiled to be estimated. Methods - Cell Culture: Lung adenocarcinoma cell lines NCI-H1975 and HCC827 were grown in Roswell Park Memorial Institute (RPMI) 1640 medium with 10% fetal calf serum and 1% penicillin-streptomycin. Methods - RNA preparation: mRNA was extracted using a Qiagen RNA miniprep kit and purified using the NEBNext® Poly(A) mRNA Magnetic Isolation Module (E7490). Purified mRNA spiked with sequins was used for the cRNA-PCR Barcoding (SQK-PCS109 with SQK-PBK004) kit (ONT). Completed libraries were sequenced on PromethION (ONT). Reads were mapped to known genomic features of the GrCh38 reference transcriptome and RNA sequin transcriptome combined sequences at the transcript-level and single reads were then summarized into transcript-level counts using salmon software (Patro et al. 2017).

Nanopore RNA-seq of human cell lines treated with or without nicotinamide adenine dinucleotide (NAD+)

Project description:Investigation of transcriptome changes in four human cell lines (BJ, BJ-5ta, U2OS and HeLa) after treatment for 24 hours with nicotinamide adenine dinucleotide (NAD+). Cells were untreated as the control condition. Nanopore sequencing of cDNA was performed after library preparation with the ONT SQK-PCB109 kit.

Transcriptome profiling of human lung cancer cell lines with synthetic "sequin" controls

Project description:Purpose: The aim of this study is to build up a transcriptomic data analysis pipeline and test its performance using synthetic "sequins" controls and lung cancer cell lines. Methods - Cell Culture: Lung adenocarcinoma cell lines NCI-H1975 and HCC827 from a range of passages (2-4) were grown on 3 separate occasions in Roswell Park Memorial Institute (RPMI) 1640 medium with 10% fetal calf serum and 1% penicillin-streptomycin. Methods - RNA preparation: Total RNA was extracted using the TRIzol reagent. 6 ng of sequins were added to 1 ug of total RNA (mix A with H1975, mix B with HCC827). Methods - Library prep: the sequin+total RNA mixtures were subjected to polyA selection (NEBNext PolyA E7490) and library prep (NEBNext Ultra II Directional RNA Library Prep Kit for Illumina) following manufacturer's instructions; we performed 9 PCR cycles

Nanopore RNA-seq of human osteosarcoma cell line U2OS treated with siRNA against MDC1, PLRG1, or control siRNA with or without pladienolide B

Project description:The purpose was to investigate transcript and splicing changes in U2OS cells following siRNA-mediated depletion of MDC1 and PLRG1 or treatment with the splicing inhibitor pladienolide B. Cells were treated with control siRNA as control condition. Nanopore sequencing of cDNA was performed after library preparation with ONT kits SQK-PCS109 and SQK-PBK004.

Identifying crossover locations in an Arabidopsis thaliana Col x Ler F2 population using Nanopore-seq and COmapper

Project description:Genomic DNA from 55 wild type Col x Ler F2 individuals was extracted using the CTAB method. Equal amounts of DNA from these 55 plants were pooled into two groups (pool 1 = 4 plants; pool 2 = 51 plants), and nine micrograms of gDNA from each pool was used to generate Nanopore sequencing libraries with the Ligation Sequencing Kit V14 (Nanopore, SQK-LSK114). The libraries were sequenced independently using PromethION (BGI, Hong Kong).

Evaluation of three small RNA library preparation kits on serum-derived RNA

Project description:We evaluated the effect of the small RNA library preparation method on 5' tRNA-halves and miRNA abundance in libraries prepared from serum RNA using three commercially available small RNA library preparation kits (TruSeq small RNA library preparation kit v2 (Illumina), TailorMix miRNA sample preparation kit v2 (Seqmatic) and the NEBNext Multiplex Small RNA library prep kit (New England Biolabs)). RNA isolated from 100 µl of serum collected from healthy mice was used as input for the preparation of a small RNA library in duplicate and libraries were single end sequenced.

U1 RAP-RNA-Seq analysis of A2Lox mouse embryonic stem cells treated with a control or Srrt-specific siRNA

Project description:The experiment was carried out to examine the effect of Srrt knockdown on the U1 snRNP/pre-mRNA interaction pattern. A2Lox mouse embryonic stem cells were transfected with either an Srrt-specific or a non-targeting siRNA. 48 hours post transfection the cells were cross-linked using 2% formaldehyde and lysed. RNA was partially fragmented by sonication, hybridized with U1 snRNA-specific biotinilated probes and pulled down. U1-associated RNA sequences were then purified and RNA-seq libraries were generated using a NEBNext® rRNA Depletion Kit and NEBNext® Ultra8482 II Directional RNA Library Preparation kit. Paired-end sequencing was performed using a HiSeq4000 75bp platform.
