Summary (written by the submitters)
Vascular smooth muscle cells (SMCs) normally exist in a contractile state but can undergo fate switching to produce a variety of cell phenotypes in response to pathologic stimuli. In atherosclerosis, these phenotypically modulated SMCs play a critical role in determining plaque composition and the risk of major adverse cardiovascular events.

We found that PRDM16, a transcription factor that has been genetically implicated in cardiovascular disease, is highly expressed in arterial SMCs, and downregulated during SMC fate switching in human and mouse atherosclerosis. Deletion of Prdm16 in SMCs of mice activates the synthetic modulation program in arteries under homeostatic conditions. Upon exposure to atherogenic conditions, these mice form strikingly dense, SMC-rich, fibroproliferative plaques that contain few foam cells. Acute deletion of Prdm16 in SMCs triggers a similar fibrotic response, resulting in the formation of collagen-rich lesions with thick fibrous caps – a hallmark of enhanced lesion stability. Reciprocally, ectopic expression of PRDM16 in cultured cells is sufficient to block SMC synthetic processes, including migration, proliferation, and fibrosis. Mechanistically, PRDM16 binds to chromatin and decreases activating histone marks at synthetic genes. Altogether, our results define PRDM16 as a specific gatekeeper of the synthetic SMC switch and reveal that PRDM16 levels in SMCs predetermine atherogenic lesion composition.

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 GSE305272_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1304970 and SRA study SRP608477. Searching any of these in the dataset finder brings you back here.
