RNA-seq of a panel of human normal and cancer cell lines

ABSTRACT: We performed poly(A)+ stranded RNA-seq of a panel of human primary or transformed cell lines (BJ, IMR90, MRC5, K562, HCT116, HeLa S3, HepG2, MCF7, HEK-293, HEK-293T, 2102Ep). In parallel, we determined the genomic location and DNA methylation levels of human full-length LINE-1 elements (L1) from the same cell lines using bs-ATLAS-seq (E-MTAB-10895). To link DNA methylation and L1 expression, we used cell pellets from the same cell culture to perform both RNA-seq and bs-ATLAS-seq.

Genome-wide identification and DNA methylation of human full-length LINE-1 (L1) retrotransposons in a panel of normal and cancer cell lines.

Project description:We used bs-ATLAS-seq to comprehensively map the genomic location and assess the DNA methylation status of human full-length LINE-1 elements (L1). The approach is focused on the youngest family (L1HS), but it also catches a significant fraction of L1PA2 to L1PA8 elements. This was performed in a panel of 12 human primary or transformed cell lines (BJ, IMR90, MRC5, H1, K562, HCT116, HeLa S3, HepG2, MCF7, HEK-293, HEK-293T, 2102Ep).

A comprehensive map of L1HS-Ta retrotransposons in a panel of human cells obtained by ATLAS-seq.

Project description:We used ATLAS-seq to comprehensively map the genomic location of LINE-1 elements belonging to the youngest and potentially polymorphic subfamily (L1HS-Ta). This was performed in a panel of 12 human primary or transformed cell lines (BJ, IMR90, MRC5, H1, K562, HCT116, HeLa S3, HepG2, MCF7, HEK-293, HEK-293T, 2102Ep). In brief, ATLAS-seq relies on the random mechanical fragmentation of the genomic DNA to ensure high-coverage, ligation of adapter sequences, suppression PCR-amplification of L1HS-Ta element junctions, and Ion Torrent sequencing using single-end 400 bp read chemistry. A notable aspect of ATLAS-seq is that we can obtain both L1 downstream and upstream junctions (3'- and 5'-ATLAS-seq libraries, respectively), for full-length L1 elements. Note that a 10-nt sample-specific barcode has been removed at the 5' end of the reads in the .fastq files upon demultiplexing. This was achieved using cutadapt v1.9.2.dev0 (with the following parameters: -e 0.1 -q 10 -m 25 -g <barcode_name>=^<barcode_sequence>)

RNA-seq of the human colorectal adenocarcinoma cell line HCT-116 treated with 5-aza-2’-deoxycytidine

Project description:We performed poly(A)+ stranded RNA-seq of a panel of the human colorectal adenocarcinoma cell line HCT-116 treated with 5-aza-2’-deoxycytidine. In parallel, we determined the genomic location and DNA methylation levels of human full-length LINE-1 elements (L1) from the same samples using bs-ATLAS-seq (E-MTAB-12240). To link DNA methylation and L1 expression, we used cell pellets from the same cell culture to perform both RNA-seq and bs-ATLAS-seq.

H3K4me3 and YY1 ChIP-seq of untreated 2102Ep cells

Project description:We used bs-ATLAS-seq to comprehensively map the genomic location and assess the DNA methylation status of human full-length LINE-1 elements (L1) in the genome of 2102Ep cells (E-MTAB-10895). We also achieved targeted nanopore sequencing to assay DNA methylation over a subset of loci (E-MTAB-12247). To further study the link between L1 DNA methylation and expression, we performed, in the same cell line, RNA-seq (E-MTAB-12246), as well as YY1 and H3K4me3 ChIP-seq (this dataset).

Targeted nanopore resequencing and methylation analysis of LINE-1 retrotransposons

Project description:We used the nanopore Cas9 targeted sequencing (nCATS) strategy to specifically sequence 125 L1HS-containing loci in parallel and measure their DNA methylation levels using nanopore long-read sequencing. Each targeted locus is sequenced at high coverage (~45X) with unambiguously mapped reads spanning the entire L1 element, as well as its flanking sequences over several kilobases. The genome-wide profile of L1 methylation was also assessed by bs-ATLAS-seq in the same cell lines (E-MTAB-10895).

Genome-wide identification and DNA methylation of human full-length LINE-1 (L1) retrotransposons in a panel of embryonic stem cells, induced-pluripotent stem cells and their progenitor cells

Project description:We used bs-ATLAS-seq to comprehensively map the genomic location and assess the DNA methylation status of human full-length LINE-1 elements (L1). The approach is focused on the youngest family (L1HS), but it also catches a significant fraction of L1PA2 to L1PA8 elements. This was performed in a panel of embryonic stem cells, induced-pluripotent stem cells and their progenitor cells, at different passages.

The approach is focused on the youngest family (L1HS), but it also catches a significant fraction of L1PA2 to L1PA8 elements.

RNA-seq of MCF-7 (breast adenocarcinoma) and 2102Ep (embryonic carcinoma) cells upon LINE-1 knockdown.

Project description:To measure the levels of expression of retrotransposon individual copies, and particularly of LINE-1 (L1) elements of the L1HS-Ta subfamily, we performed 2x150 bp paired-end and strand-specific RNA-seq on polyA+ RNA of MCF-7 and 2102Ep cells, which express high levels of L1. To confirm the origin of the L1-specific signal, we also performed RNA-seq upon shRNA-mediated L1 knockdown. sh960 relates to a scramble shRNA control. sh1083 and sh1085 relate to two distinct shRNAs directed against the ORF1 region of L1.3 (GenBank L19088) as a prototype L1HS-Ta.

Single-cell identification of L1HS-Ta retrotransposons in preimplantation embryos by ATLAS-seq

Project description:We used ATLAS-seq to comprehensively map the genomic location of LINE-1 elements belonging to the youngest and potentially polymorphic subfamily (L1HS-Ta). This was performed in single-cells of 2 preimplantation embryos (E3 and E6) as well as from the remaining inner cell mass (denoted T). In brief, single cells were isolated from the inner cell mass of preimplantation embryos by laser drilling and micromanipulation. Whole-genome Multiple Displacement Amplification was performed on each isolated single cells, as well as on the remaining cells of the inner cell mass as a population (samples labelled 'T'). Then we applied ATLAS-seq to map L1HS-Ta retrotransposons. This approach relies on the random mechanical fragmentation of the genomic DNA to ensure high-coverage, ligation of adapter sequences, suppression PCR-amplification of L1HS-Ta element junctions, and Ion Torrent sequencing using single-end 400 bp read chemistry. A notable aspect of ATLAS-seq is that we can obtain both L1 downstream and upstream junctions (3'- and 5'-ATLAS-seq libraries, respectively), for full-length L1 elements.
