Summary (written by the submitters)
ARID1A functions as a vital tumor suppressor whose activity usually depends on the SWI/SNF chromatin remodeling complex. ARID1A is highly mutated across human cancers, and its deficiency has been found to promote immunogenicity through impaired mismatch repair and elevated tumor mutation burden. However, little is known about the SWI/SNF-independent function of ARID1A and the subsequent consequences.

Here, we report a novel mechanism of action that ARID1A maintains heterochromatin integrity and silences endogenous satellite/retroelements, independent of SWI/SNF and microsatellite instability. Mechanistically, ARID1A recruits TRIM28 to keep the rigidity of heterochromatin. Loss of ARID1A displaces SETDB1 from TRIM28-contraining heterochromatin complex to induce the derepression of H3K9me3 at endogenous satellite/retroelement regions. The unleashed satellites and retroelements resulting from impaired ARID1A-TRIM28 interaction trigger type-I interferon immune responses, promoting tumor progression and sensitivity to PD1 blockade through both RNA- and DNA-sensing pathways. Our results shed light on the SWI/SNF-independent function of ARID1A to necessarily maintain heterochromatin integrity and safeguard the immunogenicity, potentiating the disruption of ARID1A-TRIM28 interaction as a strategy to convert ARID1A-wildtype tumors into hot to strengthen the therapeutic efficacies.

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 GSE239728_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 PRJNA1000630 and SRA study SRP452388. Searching any of these in the dataset finder brings you back here.

Study design
16 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 16 sample titles: 16 distinct titles with little repetition. 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.
