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
18 samples: 18 samples, each with a distinct title — no replicated groupsGroups 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.

SIRT1-based therapy targets a gene program involved in mitochondrial turnover in a model of retinal neurodegenerationScientific reports · 2025
Summary (written by the submitters)
The aim of this study was to examine retinal transcriptomic changes associated with optic neuritis and identify those that are reversed upon targeted expression of SIRT1 in RGCs. Conceptually, identification of transcriptional differences between SIRT1-treated and non-treated retinas will help identify genes correlating with resilience and resistance to neurodegeneration and/or the molecular pathways affected by SIRT1 overexpression.

To achieve this, we used a mouse model of experimental autoimmune encephalomyelitis (EAE)-induced optic neuritis, a commonly used model of multiple sclerosis, in which myelin oligodendrocyte-specific immune responses are induced by injecting myelin oligodendrocyte glycoprotein peptide (MOG35-55) . EAE mice develop an autoimmune demyelinating reaction characteristic of multiple sclerosis and optic neuritis which include optic nerve inflammation, axon demyelination, and loss of RGCs and visual acuity.Using this disease model and bulk RNA sequencing, we identified genes whose expression is affected by constitutive ubiquitous SIRT1 expression in SIRT1 knock-in mice, and in wild-type mice upon either targeted adeno-associated virus (AAV)-mediated SIRT1 expression in RGCs or oral gavage with resverotrol (RSV), a SIRT1 activator.

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 GSE275359_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 PRJNA1150535 and SRA study SRP527774. Searching any of these in the dataset finder brings you back here.

Study design
18 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 18 sample titles: 18 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.
