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
66 samples: 12 conditions, mostly with about 5 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)
With rising life expectancy, an increasing number of elderly individuals are undergoing surgery, highlighting the need to understand postoperative neurological complications. General anesthesia (GA) has been linked to olfactory dysfunction (OD) and cognitive impairment after surgery, but the underlying mechanisms remain poorly defined.

In this study, 20-month-old male C57BL/6 mice underwent laparotomy followed by 2 hours of isoflurane exposure to examine the molecular effects of GA and surgery up to 5 weeks post-intervention using bulk RNA sequencing (RNAseq). Transcriptomic analysis of the olfactory bulb (OB) at 1 day post-GA/operation revealed upregulation of ubiquitin-related proteins and catabolic pathways in aged mice compared to shams. In contrast, RNAseq of the hippocampus (HI) at 5 weeks post-GA/OP showed broader molecular changes, coinciding with delayed cognitive decline. Compared to young adults, aged GA/OP mice exhibited elevated expression of innate immune genes and reduced neurogenesis in the OB, along with increased gliogenesis and impaired RNA splicing in the HI.

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 GSE297195_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 PRJNA1262968 and SRA study SRP585271. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 66 samples.

How we read this: 12 replicated groups read from 66 sample titles; they account for 66 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.
