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
107 samples: 5 conditions, mostly with about 29 replicates eachGroups 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)
Loss of MOS in female mice disrupts metaphase II arrest, potentially causing infertility and germ cell tumors. Single-egg RNA sequencing revealed widespread gene expression changes in mos -/- eggs, including upregulation of cell cycle regulators like Aurka, Bub3, and Cdk7. Pathways related to RNA metabolism, transcription, and neddylation were also enriched in mos -/- eggs.
Read the full summary ↓
Notably, the transcriptome of mos -/- eggs differed from that of chemically activated eggs. These results highlight MOS as a key regulator of the meiotic cell cycle and transcriptome integrity essential for oocyte developmental competence.

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.

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE297431_RAW.tar (it can run to tens of gigabytes).

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 PRJNA1263829 and SRA study SRP586022. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 107 samples.

How we read this: 5 replicated groups read from 107 sample titles; they account for 107 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.
