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.

Summary (written by the submitters)
Although circRNA abnormalities are found in Alzheimer’s disease (AD) postmortem brains, whether and how altered circRNA landscape lead to pathological gene network changes during AD progression remain undefined. Employing our recently published experimental and computational approaches, we found genome-wide dysregulated circRNA expression and disrupted functional cooperation of circRNAs in sponging microRNAs (miRNAs) and RNA-binding proteins (RBPs) during early pathogenic progression in a mouse AD model.

In addition, we identified AD progression-associated mouse circRNAs that are conserved and affected in AD patients, which underlie malfunction of downstream microRNAs and RBPs in AD brains. An exemplar circRNA is circGigyf2, which progressively declines along with AD pathogenic severity. Furthermore, we identified AD pathological pathways centered on circGigyf2, including upstream RBPs that control circGigyf2 biogenesis and downstream miRNA-mRNA and RBP-mRNA axis regulated by circGigyf2, all affected in AD patients. Our discoveries provide strong evidence suggesting the contribution of circRNA abnormality in early AD pathogenesis.

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 GSE236683_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 PRJNA992028 and SRA study SRP447810. Searching any of these in the dataset finder brings you back here.
