What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.

Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.
Summary (written by the submitters)
The parallel disruption of multiple genes coupled with targeted transgene insertion offers a powerful strategy for more effective and precise cell engineering. However, such orthogonal editing involves the induction of multiple DNA breaks, raising safety concerns related to the risks of chromosomal translocations. Here, we present a polyfunctional CRISPR-Cas9-based strategy that enables both transgene insertion and epigenetic silencing at distinct genomic loci in a single treatment without inducing reciprocal chromosomal translocations.

This is accomplished through an optimized all-in-one epigenome editor equipped with a catalytically active Cas9, whose endonuclease activity is selectively disabled at epigenetically silenced loci by the use truncated gRNAs. As a proof of concept, we demonstrated that this platform enables efficient multi-locus editing, including functional replacement of the endogenous TCR with a tumor-selective one, targeted insertion of a prototypic CAR with either a selectable marker or an immunomodulatory receptor into a TCR locus or a ubiquitously expressed gene, and durable, multiplexed epigenetic silencing of clinically relevant genes in primary human T cells. Polyfunctional editing establishes a versatile and safe framework for orthogonal editing, broadening the scope of genome and epigenome engineering in cancer immunotherapy and beyond.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE293141_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1242875 and SRA study SRP573750. Searching any of these in the dataset finder brings you back here.
