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.
Paper
Retained introns in phototransduction genes of 5xFAD mouse retina suggest vision impairment as an early diagnostic marker for Alzheimer's diseaseScientific reports · 2025
Summary (written by the submitters)
Alzheimer’s disease (AD) is an age-related neurodegenerative disorder in which neuronal and synaptic loss of the brain leads to cognitive impairment and dementia. Therefore, the early diagnosis of AD with various biomarkers is important for the prevention and treatment. Although retina pathology is emerging biomarker that associated with AD, detailed molecular mechanisms of retinal impairments remain unclear.

Here, we identify the genome-wide dysfunction of alternative splicing in the early stage of 5xFAD transgenic mouse retina by the RNA-seq analysis. Especially, retained intron (RI) highly enriched in phototransduction and retinal genes of 1.5-month-old 5xFAD mouse retina that significantly associated with retinal physiological impairment of rod photoreceptors by electroretinogram (ERG) analysis. These results indicate that the abnormal scotopic ERG associated with global splicing impairment may be useful early detection biomarker for AD.

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 GSE274214_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 PRJNA1145411 and SRA study SRP524774. Searching any of these in the dataset finder brings you back here.
