Paper
Dual mechanism of autophagy gene repression by PHF23 and therapeutic potential of its inhibition in protein aggregation disordersNucleic acids research · 2025
Summary (written by the submitters)
Autophagy is a conserved self-digestion pathway essential for maintaining cellular homeostasis and catabolism. Under normal conditions, autophagic activity remains minimal but is rapidly upregulated in response to stresses such as nutrient deprivation. While the transcriptional and epigenetic activation of autophagy under nutrient deprived condition has been widely studied, less is known about the repression mechanisms of autophagy under normal conditions.
Read the full summary ↓
Here, we identify PHF23 as an epigenetic repressor of autophagy through a CRISPR interference (CRISPRi) screening. PHF23 inhibits the expression of autophagy genes by recruiting the NuRD complex and reducing chromatin accessibility, particularly at enhancer regions. This repressive function of PHF23 requires an intact PHD domain and is attenuated under amino acid starvation or mTOR inhibition conditions. Notably, inhibiting PHF23 enhances the autophagic clearance of pathological protein aggregates including Tau and a1 antitrypsin Z variant (ATZ), underscoring its potential as a therapeutic target in diseases characterized by proteotoxic stress.

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 GSE300094_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 PRJNA1279020 and SRA study SRP593048. Searching any of these in the dataset finder brings you back here.
