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.

12 samples: 6 × eWAT, saline injected, biol vs 6 × eWAT, epinephrine injected, biolGroups 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)
Psychological stress activates the autonomic nervous system to protect organisms through an integrated response involving changes to both behavior and metabolism. Epinephrine is an important driver of this response, activating adipose tissue lipolysis3and inducing anxiety-like behavior. Interestingly, anxiety correlates with circulating free fatty acid levels and can be alleviated by a b-blocker that does not cross the blood brain barrier suggesting a peripheral signal linking metabolism with behavior, however, to date this has not been defined.

Herein, we identify that the most upregulated secreted gene product induced by epinephrine within white adipose tissue of mice is growth differentiating factor 15 (GDF15). This increase in GDF15 occurs within one hour and is not observed in liver, brown adipose, kidney, or skeletal muscle, and is also observed with the more specific b2/3-agonist, CL316,243. Genetic inhibition of adipose triglyceride lipase (ATGL), the rate limiting enzyme for the release of free fatty acids in white adipose tissue, or genetic deletion of b-adrenergic receptors, blocks b-adrenergic induced increases in GDF15. Increases in circulating GDF15 are not derived from adipocytes but instead require free fatty acid-induced stimulation of macrophages within white adipose tissue. Remarkably, anxiety-like behavior elicited by epinephrine or restraint stress are eliminated in mice lacking the GDF15 receptor, GFRAL. Importantly in patients with severe burns, increases in catecholamines are associated with GDF15 and this relationship is eliminated with the b-blocker propranolol. These data provide important insight into the mechanisms linking metabolism and behavior and suggest that inhibition of GDF15-GFRAL signaling may be important for reducing acute anxiety.

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.

Supports a between-group comparison across 12 samples.

How we read this: 2 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.
