Project description:Whole genome sequencing (WGS) of tongue cancer samples and cell line was performed to identify the fusion gene translocation breakpoint. WGS raw data was aligned to human reference genome (GRCh38.p12) using BWA-MEM (v0.7.17). The BAM files generated were further analysed using SvABA (v1.1.3) tool to identify translocation breakpoints. The translocation breakpoints were annotated using custom scripts, using the reference GENCODE GTF (v30). The fusion breakpoints identified in the SvABA analysis were additionally confirmed using MANTA tool (v1.6.0).

Project description:Transposon insertion site sequencing (TIS) is a powerful method for associating genotype to phenotype. However, all TIS methods described to date use short nucleotide sequence reads which cannot uniquely determine the locations of transposon insertions within repeating genomic sequences where the repeat units are longer than the sequence read length. To overcome this limitation, we have developed a TIS method using Oxford Nanopore sequencing technology that generates and uses long nucleotide sequence reads; we have called this method LoRTIS (Long Read Transposon Insertion-site Sequencing). This experiment data contains sequence files generated using Nanopore and Illumina platforms. Biotin1308.fastq.gz and Biotin2508.fastq.gz are fastq files generated from nanopore technology. Rep1-Tn.fastq.gz and Rep1-Tn.fastq.gz are fastq files generated using Illumina platform. In this study, we have compared the efficiency of two methods in identification of transposon insertion sites.

Project description:We evaluated linked-read whole genome sequencing (WGS) for detection of structural chromosomal rearrangements in primary samples of varying DNA quality from 12 patients diagnosed with ALL. Linked-read WGS enabled precise, allele-specific, digital karyotyping at a base-pair resolution for a wide range of structural variants including complex rearrangements, aneuploidy assessment and gene deletions. Additional RNA-sequencing and copy number aberrations (CNA) data from Illumina Infinium arrays were also generated and assessed against the linked-read WGS data. RNA-sequencing data was used to support structural chromosomal rearrangements detected in the linked-read WGS data by detecting expressed fusion genes as a consequence of the rearrangements. Illumina Infinium arrays (450k array and/or SNP array) were used to assess CNA status to further support the findings in the linked-read WGS data. The processed CNA data from the primary ALL patient samples has been deposited to GEO. RNA-sequencing, linked-read WGS data, and raw SNP array data from the primary ALL patient samples will not be deposited because the patient/parent consent does not cover depositing data that may be used for large-scale determination of germline variants in a repository. The ALL samples were collected 10-20 years ago from pediatric patients aged 2-15 years, some whom have deceased. The linked-read WGS data and the RNA-sequencing data sets generated in the study are available upon reasonable request from the corresponding author Jessica.Nordlund@medsci.uu.se.

Project description:We sequenced DNA from a bulk of Col x Ler F2 hybrid plants (WT and recq4) using Nanopore long-read sequencing and identified crossover sites with COmapper. For nanopore sequencing of gDNA from 1,000 pooled seedlings, 10-day-old seedlings were ground in liquid nitrogen using a mortar and pestle. The ground tissue was resuspended in four volumes of CTAB buffer (1% [w/v] CTAB, 50 mM Tris-HCl pH 8.0, 0.7 M NaCl, 10 mM EDTA) and incubated at 65°C for 30 min. Following chloroform extraction, isopropanol precipitation and removal of RNAs as above, the gDNA pellet was resuspended in 150 μl TE (10 mM Tris-HCl pH 8.0, 0.1 mM EDTA) buffer and gDNA was quantified using a Qubit dsDNA Broad Range assay kit (Thermo Fisher, Q32853). Nine micrograms of gDNA from pollen or seedlings was used to construct a nanopore long-read sequencing library using a Ligation Sequencing Kit V14 (Nanopore, SQK-LSK114). The libraries were sequenced using a PromethION platform (BGI, Hong Kong).

Project description:We performed shallow whole genome sequencing (WGS) on circulating free (cf)DNA extracted from plasma or cerebrospinal fluid (CSF), and shallow WGS on the tissue DNA extracted from the biopsy in order to evaluate the correlation between the two biomaterials. After library construction and sequencing (Hiseq3000 or Ion Proton), copy number variations were called with WisecondorX.

Project description:We sequenced DNA from the leaves of ten Col x Ler F1 hybrid plants (WT and recq4) using Nanopore long-read sequencing and identified crossover sites with COmapper. These data were used as a negative control for COmapper, as no crossover sites were expected to be detected. For nanopore sequencing of gDNA from leaves, leaves from 10 5-week-old plants were ground in liquid nitrogen using a mortar and pestle. The ground tissue was resuspended in four volumes of CTAB buffer (1% [w/v] CTAB, 50 mM Tris-HCl pH 8.0, 0.7 M NaCl, 10 mM EDTA) and incubated at 65°C for 30 min.

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).
