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
Mus musculus (mouse)
Samples
10 samples: 5 × Ctx 5XFAD; Idol; Camk2a-cre WT vs 5 × Ctx 5XFAD; Idol; Camk2a-cre cKOGroups 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.

Deletion of neuronal Idol ameliorates Alzheimer's disease-related pathologies via APOE receptorsAlzheimer's & dementia : the journal of the Alzheimer's Association · 2025
Summary (written by the submitters)
Earlier studies demonstrated that overexpression of the low-density lipoprotein receptor (LDLR) decreases apolipoprotein E (APOE) levels in the brain and alleviates amyloid-beta (Aβ) pathology. We hypothesized that inhibiting the Inducible Degrader of LDLR (IDOL)- an E3 ubiquitin ligase that ubiquitinates LDLR for degradation- would increase endogenous LDLR levels and decrease amyloid pathology.

Previously, we demonstrated that the deletion of Idol increased LDLR levels and reduced amyloid deposition in a transgenic mouse model of Aβ-amyloidosis. However, the cellular mechanisms underlying these beneficial effects were unknown. Here, we investigate the cell-type-specific contribution of Idol deletion to amyloid pathology by generating Idol conditional knock-out mouse models. We demonstrate that deletion of neuronal, but not microglial, Idol reduces amyloid accumulation in the 5XFAD transgenic mouse model. Furthermore, only neuronal Idol deletion alters brain LDLR and APOE levels, pointing to the critical role of the neuronal LDLR-APOE axis in modulating Aβ accumulation.

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 GSE301451_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: 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 PRJNA1285258 and SRA study SRP597920. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 10 samples.

How we read this: 2 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.
