Summary (written by the submitters)
Activation of innate inflammatory signaling and tumor-specific antigen presentation in cancer cells provides a foundation for anti-cancer immunotherapies. Here, we show that Insulin-like Growth Factor 2 mRNA-Binding Proteins (IGF2BP1, IGF2BP2, and IGF2BP3), which are upregulated across various human malignancies, including acute myeloid leukemia (AML), suppress the activity of RNA-sensing pattern recognition receptors and downstream ISRE- and NF-κB-driven transcription.
Read the full summary ↓
IGF2BPs exert a strong inhibitory effect on RIG-I signaling. This suppression is most pronounced when all three paralogs are co-expressed, particularly in embryonic-like hematoendothelial and leukemia stem cells and is at least partly mediated through IGF2BP-dependent regulation of negative regulators of immune signaling. Genetic and pharmacological inhibition of IGF2BPs activates innate immune signaling and induces MHC class I gene expression in AML, highlighting a promising strategy for RIG-I- and TLR-based cancer immunotherapies.

This dataset
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 GSE311644_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1370059 and SRA study SRP649272. Searching any of these in the dataset finder brings you back here.

Study design
3 × ATAC-Seq, IGF2BP1 Knockout, vs 2 × ATAC-Seq, CRISPR Control, vs 2 × ATAC-Seq, IGF2BP2 Knockout, vs 2 × ATAC-Seq, IGF2BP3 Knockout,

Supports a case/control comparison: 7 samples read as cases, 2 as controls.

How we read this: 4 replicated groups read from 9 sample titles; they account for 9 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.
