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)
Major depressive disorder (MDD) disproportionately affects women, yet the molecular mechanisms underlying female vulnerability remain poorly understood. The nucleus accumbens (NAc), a reward circuitry hub, is central to stress- and depression-related pathology. While NAc medium spiny neuron (MSN) transcriptional adaptations have been characterized in stressed male rodents, much less is known about female adaptations.

To address this, we exposed female D1-Cre-RiboTag and A2A-Cre-RiboTag mice to chronic witness defeat stress (CWDS) and classified them as high- or low-social interactors. Ribosome-associated mRNA was isolated from MSN subtypes and analyzed by RNA sequencing, differential gene expression analysis (DEG), and weighted gene co-expression network analysis (WGCNA). Cross-species consensus WGCNA with male mouse and human transcriptomic datasets was performed to identify conserved, sex-specific signatures. We detected 9 differentially expressed genes (DEGs) in D1-MSNs and 630 in A2A-MSNs (FDR < 0.05). In D1-MSNs, DEGs were primarily upregulated in low interactors and enriched for energy homeostasis and cell adhesion. A2A-MSN DEGs included upregulated structural genes and downregulated neurotransmission-related genes. WGCNA identified 9 significant D1- and 5 significant A2A-MSN modules, with the most impacted enriched for PI3K-Akt-mTOR signaling and regulated by Nf1. Consensus analysis revealed a stress-associated, sex- and subtype-specific module enriched for PI3K-Akt-mTOR signaling conserved across mice and humans. These findings reveal female-specific MSN transcriptional adaptations to chronic social stress and implicate PI3K-Akt-mTOR signaling as a convergent molecular pathway. By highlighting MSN subtype-specific vulnerabilities, this work suggests potential therapeutic targets for alleviating stress-induced pathology in women with MDD.

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 GSE315159_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.

Raw reads on ENA ↗

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 PRJNA1395072 and SRA study SRP658644. Searching any of these in the dataset finder brings you back here.
