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

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)
Hypoxic-ischemic (HI) brain injury in premature infants causes major cognitive deficits and cerebral palsy (CP). Premature infants are devoid of a placental supply of Allopregnanolone (ALLO). ALLO is essential for brain growth and neuronal and glial cell survival. Goals and objectives: To assess whether ALLO supplementation mitigates hypoxic-ischemic (HI) brain injury.

To conduct a comparative analysis of RNA sequencing between ALLO-treated HI mice and untreated HI mice. To elucidate the mechanism of action of ALLO in the context of HI brain injury.Methods: A neonate mouse model of HI was treated with 3 doses of ALLO (10mg/kg/dose IP) on P5, P8, and P11 or saline. Molecular, biochemical, histopathological, and transcriptome studies were done on P12-P14. Others were examined at P60 for neurobehavioral analysis. Results: ALLO-treated HI mice showed significant improvement in neuro-regeneration, myelination, motor function, coordination, learning, and memory, along with significant attenuation of neuro-inflammation. RNA sequencing analysis showed that the ALLO-treated HI group had a significant downregulation of inflammatory responsive genes, reduced glutamate excitotoxicity, improved neurogenesis, and improved neural repair, restoring neural integrity and cognitive function. Using electron microscopy, mitochondrial ultrastructure in hippocampal neurons showed small, fragmented mitochondria, with loss of mitochondrial membrane and cristae in HI group, while ALLO protected mitochondrial ultrastructure after HI exposure. Conclusion: ALLO is a unique natural neurotherapeutic steroid in HI injury through promoting neurogenesis, neurodegeneration, and oligodendrogenesis, reducing neuroinflammation and glutamate excitotoxicity, and preserving mitochondrial structure and function.

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 GSE302721_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.

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 PRJNA1290410 and SRA study SRP600260. Searching any of these in the dataset finder brings you back here.

Study design
10 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 10 sample titles: 10 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.
