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
24 samples: 12 × BATdKO WT vs 12 × BATdKO KOGroups 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)
Brown adipose tissue (BAT) is a key thermogenic organ, whose activation in response to cold environmental temperatures and β-adrenergic stimulation requires the proper function of the NCOR/HDAC3 corepressor complex in brown adipocytes. The NCOR/HDAC3 complex is large, and multi-component, including the transducin beta-like 1 (TBL1) and TBL1-related 1 (TBLR1) proteins.

Loss of TBL1 in the hepatocytes and TBLR1 in the white adipocytes has been shown to impair fasting- and β-adrenergic-induced lipolysis. However, their roles in BAT thermogenesis remain unknown. Here, we report that deletion of TBLR1 alone in brown adipocytes does not impair the adaptive thermogenic response to prolonged cold exposure. In contrast, simultaneous deletion of TBL1 and TBLR1 dampens β-adrenergic-induced lipolysis and mitochondrial respiration in cultured mouse brown adipocytes. Transgenic mice with UCP1-Cre mediated double deletion of TBLR1 and TBL1 exhibit reduced whole-body energy expenditure during prolonged cold exposure, lower core body temperature, increased appearance of unilocular adipocytes in BAT, and suppressed expression of metabolic and myogenic PRDM16 target genes. Also, we found that TBLR1 and TBL1 interact with HDAC3 and PRDM16 in brown adipocytes, suggesting a direct involvement in PRDM16-controlled transcriptional program. These findings identify TBLR1/TBL1 complex as a critical regulator of BAT adaptation to prolonged cold and systemic energy homeostasis, shedding light on the context-dependent functions of corepressor complexes.

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 GSE298802_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 PRJNA1271324 and SRA study SRP589509. Searching any of these in the dataset finder brings you back here.

Study design
12 × BATdKO WT vs 12 × BATdKO KO

Supports a between-group comparison across 24 samples.

How we read this: 2 replicated groups read from 24 sample titles; they account for 24 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.
