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
12 samples: 3 × wild type C2C12 vs 3 × wild type C2C12 with T3 treatment vs 3 × Thrap3 KO C2C12 vs 3 × Thrap3 KO C2C12 with T3 treatmentGroups 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)
Thyroid hormone (TH) secreted by the thyroid gland plays essential roles in regulating metabolism, development, and nervous system function. Thyroid hormone receptor-associated protein 3 (THRAP3) is a nuclear coactivator that interacts with the thyroid hormone receptor (TR) and facilitates target gene regulation through the mediator complex.

Although this mechanism has been well studied in other tissues, the specific role of THRAP3 in skeletal muscle remains unclear. Here we investigated the function of THRAP3 in skeletal muscle using Thrap3 knockout (KO) C2C12 cells. Loss of THRAP3 significantly suppressed the expression of key myogenic regulatory factors, including Myod1, Mef2c, and myosin heavy chain genes, resulting in impaired myogenic differentiation and muscle diameter. Furthermore, we found that THRAP3 influences triiodothyronine (T3)-induced gene expression, suggesting that it cooperatively modulates thyroid hormone signaling in muscle cells. Taken together, our findings identify THRAP3 as a novel regulator of myogenesis and indicate that it supports T3 activity by coordinating thyroid hormone–responsive gene expression in skeletal muscle.

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 GSE306461_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 PRJNA1310944 and SRA study SRP612716. Searching any of these in the dataset finder brings you back here.

Study design
3 × wild type C2C12 vs 3 × wild type C2C12 with T3 treatment vs 3 × Thrap3 KO C2C12 vs 3 × Thrap3 KO C2C12 with T3 treatment

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 sample titles; they account for 12 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.
