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
14 samples: 14 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.
Paper
Resistance exercise in early-stage ALS patients, ALSFRS-R, Sickness Impact Profile ALS-19, and muscle transcriptome: a pilot studyScientific reports · 2024
Summary (written by the submitters)
Amyotrophic lateral sclerosis (ALS) patients lose motor and neuromuscular function but lack effective treatments. The objective of this study was to evaluate the effect of moderate-level exercise on ALS scores, neuromuscular function, and transcriptome in ALS patients. Methods: A pilot open-label, non-randomized clinical trial was conducted in seven individuals with early-stage ALS.

Participants were given three months of moderate-level home-based resistance exercise focusing on the quadriceps muscles. Before and after the exercise program, participants were evaluated by quantifiable outcome measures using bilateral quadriceps strength with manual muscle testing and handheld dynamometers and functional outcome measures using five times sit-to-stand and Timed-Up-and-Go. In addition, changes in the transcriptome and mitochondrial respiration of exercised muscles were compared before and after the exercise. Results: The exercise program significantly improved the Sickness Impact Profile ALS-19 (SIP/ALS-19) and did not cause serious adverse events to the patients. ALSFRS-R, quantifiable outcome measures, functional outcome measures, and muscle respiration values did not change by the exercise program. Transcriptome analysis revealed that exercise reverted the expression level of genes decreased in ALS, including PVALB. Conclusions: Three months of moderate-level resistance exercise is not detrimental for the patients and may have a positive effect on patients’ QOL.

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 GSE250455_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 PRJNA1054094 and SRA study SRP478620. Searching any of these in the dataset finder brings you back here.

Study design
14 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 14 sample titles: 14 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.
