Summary (written by the submitters)
Death domain-associated protein (Daxx) is one of the two main H3.3 chaperones in mammalian cells and acts as key repressor of RTEs of viral origin. In the present study, we found that Daxx is an IFN-stimulated gene mediating repression of RTEs and IFN-stimulated genes (ISGs) upon inflammatory stimuli in microglia. Using both bulk and single-cell genomics, we demonstrated that shortly after Daxx loss microglia displayed co-expression of DNA damage/p53, IFN/developmental and DAM-like signatures, suggesting lowering of the epigenetic barrier and increased plasticity.

With time, Daxx-deficient microglia become restricted to a DAM-like/ApoeHIGH profile, associated with decreased synaptic puncta and altered behavior. Finally, brains from older microglia-specific Daxx KO mice accumulate ApoE protein along with lysosomal markers. Together, our data revealed a role of Daxx in maintenance of the homeostatic state of microglia in the adult brain, with implications for our understanding of the relationship between loss of epigenetic barriers and neuroinflammation and its potential implications for brain function and aging.

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 GSE309782_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 PRJNA1363165 and SRA study SRP644315. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 10 samples.

How we read this: 4 replicated groups read from 10 sample titles; they account for 10 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.
