Project description:Rapidly increased studies by third-generation sequencing [Pacific Biosciences (Pacbio) and Oxford Nanopore Technologies (ONT)] have been used in all kinds of research areas. Among them, the plant full-length single-molecule transcriptome studies were most used by Pacbio while ONT was rarely used. Therefore, in this study, we developed ONT RNA-sequencing methods in plants. We performed a detailed evaluation of reads from Pacbio and Nanopore PCR cDNA (ONT Pc) sequencing in plants (Arabidopsis), including the characteristics of raw data and identification of transcripts. We aimed to provide a valuable reference for applications of ONT in plant transcriptome analysis.
Project description:This study is a comparison of sequencing technologies and library preparations protocols performed on RNA extracted from Huh-7 cells, a human hepatocellular carcinoma (HCC) cell line, for which a few characteristic fusion transcripts have previously been reported. The sequencing platforms and library types include Oxford Nanopore Technologies (ONT) MinION direct-cDNA, ONT MinION direct-RNA and ONT MinION PCR-cDNA, PacBio Revio Kinnex sequencing. Additionally, this study includes matched short-read sequencing data from the Illumina NovaSeq platform.
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.
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.
