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.
Organism
Homo sapiens (human)
Topic
Acute myeloid leukemiaThis series is part of our curated briefing on it.
Samples
24 samples: 8 conditions, mostly in triplicateGroups are read from the sample names, not from the paper. Check the list below.
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)
Chimeric antigen receptor (CAR) T cells specific for myeloid-associated antigens expressed on the cell surface of acute myeloid leukemia (AML) cause depletion of normal myeloid progenitor cells. We developed a CAR specific for a human Leucocyte Histocompatibility Antigen (HLA)-A*02:01-restricted peptide of the cathepsin G protein, which is a myeloid-restricted protein expressed in the cytoplasm of myeloid leukemic blasts.

Cathepsin G-specific CAR (CG1.CAR) T cells were further engineered to increase their functional avidity. Specifically, we developed CG1.CAR-T cells co-expressing the lymphocyte-specific protein tyrosine kinase (LCK) and duplicated CD3ζ chain, which allows the functional recognition of the CG1 peptide as low as 0.025 µM. Optimized CG1.CAR T cells displayed antileukemia effects in vitro and in vivo in AML patientderived-xenotransplant (PDX) mouse models and did not cause hematopoietic toxicity in colony assays and humanized mice. Mechanistically, LCK overexpression in CG1.CAR-T cells caused transcriptional modifications characterized by the overexpression of mitochondrial-encoded electron transport chain components that were correlated with increased mitochondrial mass and improved respiratory capacity. Based on these data, CG1.CAR-T cells hold clinical potential for the treatment of AML.

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 GSE300381_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.

Raw reads on ENA ↗

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 PRJNA1280174. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 24 samples.

How we read this: 8 replicated groups read from 24 sample titles; they account for 24 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
