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
Mus musculus (mouse)
Samples
96 samples: 96 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.

Summary (written by the submitters)
Major depressive disorder (MDD) is characterized by symptom heterogeneity and sex differences in prevalence. To gain insight into these sex differences, we utilized the subchronic variable stress paradigm (SCVS) in which female mice are susceptible, while males are behaviorally resilient. We used the Four Core Genotypes mice to differentiate between sex chromosome complement (XX vs.

XY) and gonad type (ovaries vs. testes) in stress susceptibility, uncoupling these factors by removing the testes-determining SRY gene from the Y chromosome. Mice were subjected to SCVS followed by assays to assess anxiety-/depressive-like behaviors. Regardless of gonads, XX mice were stress susceptible, while XY mice were stress resilient, underscoring the importance of sex chromosome effects to sex differences in susceptibility to SCVS, independent of gonad type. We then performed RNA-sequencing of the prefrontal cortex (PFC) and nucleus accumbens (NAc). Consistent with human MDD and previous rodent SCVS findings, there was little overlap in genes altered by SCVS across sex. In stress susceptible XX mice, stress exposure altered pathways related to immune function, while in resilient XY mice, stress exposure altered pathways involved in neuronal function. There was brain region specificity to how sex chromosome complement and gonad type contributed to sex-specific stress effects. In the NAc, sex chromosome complement was the primary contributor to stress-induced gene expression, while in the PFC, both sex chromosome complement and gonad type contributed. These findings underscore a complex relationship between sex chromosome complement and gonadal factors in shaping stress vulnerability, partly through immune-related pathways.

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 GSE330309_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.

Study design
96 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 96 sample titles: 96 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.
