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
22 samples: 22 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)
SMC3 is a chromatin binding factor that plays central roles in genome organization and in proper neurodevelopment. Mutations in SMC3 gene (SMC3) induce neurodevelopmental and behavioral phenotypes in humans, including changes in anxiety behavior and self-injury. However, it is not clear what are the exact roles of SMC3 in behavior in adulthood or if its effects are only developmental.

Using an adulthood forebrain excitatory neuron specific Smc3 knockout mouse model, the current study determined specific sex-dependent effects of SMC3 ablation during the adulthood. Behavioral tests identified anxiolytic effects of Smc3 knockout in females and anxiogenic effects in males four weeks after initiation of adulthood knockout. The prefrontal cortex, a regulator of anxiety behavior, also displayed sex-dependent effects in dendritic complexity. Transcriptional analysis revealed differential effects of Smc3 knockout in males and females, including changes in anxiety-related genes and relevant transcriptional pathways. While anxiety behavior was sex-specific, both males and females developed self-injury behavior at approximately ten weeks after induction of knockout. The current study demonstrates that neuronal SMC3 regulates anxiety during the adulthood in a sex-specific manner.

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 GSE270835_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 PRJNA1128600 and SRA study SRP516243. Searching any of these in the dataset finder brings you back here.

Study design
22 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 22 sample titles: 22 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.
