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
20 samples: 5 × Sham_control_A vs 5 × Sham_mimic_B vs 5 × OV_control_C vs 5 × OV_mimic_DGroups 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.
Paper
miRNA-1 regulation is necessary for mechanical overload-induced muscle hypertrophy in male micePhysiological reports · 2025
Summary (written by the submitters)
MicroRNAs (miRNAs) are small, non-coding RNAs that play a critical role in regulating gene expression post-transcriptionally. Skeletal muscle-specific miRNAs, including miR-1, are important for skeletal muscle development and maintenance. In response to mechanical loading, skeletal muscle levels of miR-1 decrease by approximately 50%, suggesting a potential involvement in muscle hypertrophy.
Read the full summary ↓
In the current investigation, we hypothesized that a reduction of miR-1 levels in response to mechanical loading would be necessary for skeletal muscle growth to occur. By significantly elevating miR-1 levels during the hypertrophic process via lentiviral delivery, we observed a blunted growth response in the plantaris muscle subjected to synergist ablation. A deeper RNA-based integrative analysis (transcriptomics and RNA eCLIP) indicates that miR-1 inhibits the expression of Itm2a and Melusin, two membrane-related proteins. While their exact mechanism in muscle hypertrophy is yet to be identified, our results suggest that miR-1-regulated membrane proteins are important for skeletal muscle hypertrophy.

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 GSE265982_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 PRJNA1105087 and SRA study SRP504287. Searching any of these in the dataset finder brings you back here.

Study design
5 × Sham_control_A vs 5 × Sham_mimic_B vs 5 × OV_control_C vs 5 × OV_mimic_D

Supports a between-group comparison across 20 samples.

How we read this: 4 replicated groups read from 20 sample titles; they account for 20 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.
