Long-read transcriptome profiling of human lung cancer cell lines

ABSTRACT: 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).

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

Project description: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).

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

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).

Nanopore RNA-seq of polyA+ RNA from HAP1 and HEK293 cell lines

Project description:Sequencing was performed to assess the ability of Nanopore direct cDNA and native RNA sequencing to characterise human transcriptomes. Total RNA was extracted from either HAP1 or HEK293 cells, and the polyA+ fraction isolated using oligodT dynabeads. Libraries were prepared using Oxford Nanopore Technologies (ONT) kits according to manufacturers instructions. Samples were then sequenced on ONT R9.4 flow cells to generate fast5 raw reads in the ONT MinKNOW software. Fast5 reads were then base-called using the ONT Albacore software to generate Fastq reads.
