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.

Summary (written by the submitters)
Exposure to excessive noise levels can result in hearing impairment. Currently, there are no effective pharmacological interventions available for the prevention of noise-induced hearing loss. This study was designed to investigate the protective effects of brimonidine, an α2-adrenergic receptor agonist, against noise-induced inner ear damage in mice, as well as to explore the underlying mechanisms.
Read the full summary ↓
Eight-week-old male C57BL/6 mice were randomly assigned to one of three experimental groups: a control group, a noise exposure (NE) group (exposed to broadband noise, 8–16 kHz, at 100 dB SPL for 2 hours), and a brimonidine-treated group (which received intraperitoneal injections of 1 mg/kg brimonidine prior to noise exposure). Our findings demonstrate that brimonidine significantly attenuates noise-induced hearing loss in young adult mice. Furthermore, brimonidine markedly reduces glutamate (Glu) accumulation in the inner ear. RNA sequencing analysis suggests that brimonidine exerts its protective effects, in part, through the downregulation of inflammatory cytokines and immunoglobulin-related pathways. These results indicate that brimonidine is a promising pharmacological agent for the prevention of noise-induced hearing loss.

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 GSE307393_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 PRJNA1320646 and SRA study SRP617743. Searching any of these in the dataset finder brings you back here.

Study design
7 × NE vs 7 × Bri vs 3 × controll

Supports a between-group comparison across 17 samples.

How we read this: 3 replicated groups read from 17 sample titles; they account for 17 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.
