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
Homo sapiens (human)
Samples
22 samples: 11 conditions, mostly in duplicateGroups 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.

Summary (written by the submitters)
Transactive response DNA binding protein 43 kDa (TDP-43) is a protein that regulates splicing, the loss of which underlies the pathophysiology of a variety of neurodegenerative disorders, including amyotrophic lateral sclerosis and frontotemporal dementia (ALS-FTD). In disease states, TDP-43 is cleared from the nucleus of neurons, leading to the loss of its splicing repressor function and the aberrant inclusion of cryptic exons.
Read the full summary ↓
Frequent inclusion of premature termination codons (PTCs) by cryptic exons leads to degradation of cryptic mRNA by nonsense-mediated mRNA decay (NMD). However, detection of cryptic exons relies on inefficient NMD; therefore cryptic exons efficiently targeted and eliminated by NMD remain undetectable through conventional RNA-sequencing. Here we generated a comprehensive set of neuronal targets of TDP-43 in human IPSC-derived i3Neurons (i3N) by combining TDP-43 knockdown with inhibition of several factors regulating NMD, and identified various cryptic exons that were either underestimated or entirely undetected by TDP-43 knockdown alone.

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 GSE307054_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 PRJNA1235234 and SRA study SRP569920. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 22 samples.

How we read this: 11 replicated groups read from 22 sample titles; they account for 22 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.
