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

20 samples: 5 × RiboTag, Fus+/+, biol vs 5 × RiboTag, Fus d14/d14, biol vs 5 × Total RNA, Fus+/+, biol vs 5 × Total RNA, Fus d14/d14, biolGroups 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)
Mutations in the RNA-binding protein FUS cause aggressive, early-onset forms of amyotrophic lateral sclerosis (ALS), leading to the progressive degeneration of the neuromuscular system. These mutations drive nuclear depletion and cytoplasmic mislocalisation of FUS, resulting in both loss and gain of function. We investigated these mechanisms and their impact on key pathophysiological processes in vivo, using a novel FUS-ALS mouse model.

Adult mice presented widespread transcriptomic alterations consistent with nuclear loss of function, while translatome analysis revealed specific deficits associated with aberrant FUS-dependent cytoplasmic partitioning and gain of function. Mutant FUS expression selectively impaired neuromuscular junction (NMJ) innervation in FUS-ALS females. However, NMJ reinnervation following sciatic nerve crush was equally perturbed in homozygous mutants of both sexes, indicating impaired regeneration and damage responses. Additionally, we observed cargo-specific alterations in axonal transport, a process critical for neuronal function and maintenance; in vivo mitochondrial transport was impaired in homozygous FUS-ALS mice, whereas the retrograde transport of signalling endosomes was again only affected in mutant females, strengthening the link between endosomal transport impairment and NMJ denervation in ALS. Altogether, our findings establish FUS-ALS homozygous mice as a valuable model for investigating early cellular impairments driving ALS pathology, and identify broader and sex-dependent motor neuron dysfunction in FUS-ALS pathogenesis.

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.

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 PRJNA1269487 and SRA study SRP588539. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 20 samples.

How we read this: 4 replicated groups read from 20 sample titles; they account for 20 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.
