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.

Summary (written by the submitters)
Background: Adolescence is a critical period of vulnerability to depression, yet most evidence for the antidepressant effects of exercise derives from adult models. This study aims to investigate the effects of aerobic exercise and identify its associated molecular changes in the adolescent depression mouse model. Methods: A chronic social defeat stress (CSDS) model was established in adolescent male C57BL/6J mice to induce depression-like behaviors.

Thirty-six mice were randomly assigned to three groups: control (CG), model (MG), and model plus exercise (ME). MG and ME mice were subjected to CSDS for two weeks (days 7–20), while ME mice additionally received three weeks of aerobic treadmill training covering the whole CSDS period (days 0–20). Behavioral tests were conducted on days 21–26, followed by the collection of serum and hippocampal tissues for molecular, histological, and transcriptomic analyses. Results: CSDS induced significant depression-like behaviors in adolescent male mice, including social avoidance, anhedonia, and behavioral despair, all of which were effectively alleviated by aerobic exercise. Aerobic exercise appeared to mitigate CSDS-induced neural damage and maintain hippocampal tissue integrity. Moreover, aerobic exercise increased serum levels of serotonin. Transcriptomic analysis identified 587 differentially expressed genes (DEGs). Among these genes, 59 overlapping DEGs were regulated by both CSDS and exercise, and were enriched in carbohydrate metabolism and cholinergic signaling pathways. Conclusions: Aerobic exercise alleviates depression-like behaviors in adolescent male mice, possibly by modulating hippocampal gene expression – especially in cholinergic and carbohydrate metabolism pathways – which provides potential clues to how exercise could influence peripheral monoamine levels and hippocampal structural integrity. These putative mechanisms require further investigation.

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.

Supports a between-group comparison across 18 samples.

How we read this: 3 replicated groups read from 18 sample titles; they account for 18 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.
