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)
Our study aims to elucidate the role of lncRNA-mRNA regulatory networks in AF recurrence after catheter ablation. We performed RNA sequencing to profile the transcriptomes of 5 samples from atrial fibrillation recurrence and 5 samples from sinus rhythm maintenance. 96 differentially expressed genes (DEGs) and 203 differentially expressed long non-coding RNAs (DE-lncRNAs) were identified between atrial fibrillation recurrence group and sinus rhythm maintenance group.
Read the full summary ↓
Gene Ontology (GO) analysis showed that DEGs were enriched in “regulation of immune response”, and “regulation of immune system process” for biological processes (BP), enriched in “extracellular matrix”, “cell-cell junction” for cellular components (CC), and enriched in “signaling adaptor activity”, “protein-macromolecule adaptor activity” for molecular functions (MF). For KEGG analysis, DEGs are associated with “PI3K-Akt signaling pathway”, “MAPK signaling pathway”. 9 hub genes (MMP9, IGF2, FGFR1, HSPG2, GZMB, PEG10, GNLY, COL6A1, and KCNE3) were identified through the Protein-Protein Interaction network. LncRNA-TMEM51-AS1-201 was identified as a core regulator and may impact AF recurrence after catheter ablation by regulating “COL6A1, FGFR1, HSPG2, and IGF2.”

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 GSE245886_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 PRJNA1030359 and SRA study SRP467548. Searching any of these in the dataset finder brings you back here.
