Summary (written by the submitters)
Obesity has been known to be associated with psoriasis, negatively affecting its prevalence, severity, and treatment response. However, a detailed systemic inflammatory microenvironment in obesity-associated psoriasis has not been extensively investigated. To explore this further, we used a mouse model of psoriasis induced by topical application of imiquimod or injection of IL-23.
Read the full summary ↓
We found that obese mice exhibited systemic inflammatory responses when exposed to imiquimod, with increased expression of inflammatory cytokines in the skin and elevated serum levels of mediators implicated in psoriasis pathogenesis. Notably, imiquimod also caused a significant decrease in body weight and fat, which was more pronounced in obese mice, resulting a thinner subcutaneous fat layer. Further analysis revealed higher macrophage infiltration, upregulated genes relating to the inflammatory response, and increased expression of necrosis-associated molecules in the perigonadal fat of imiquimod-treated obese mice than in lean mice. IL-23 injection induced comparable pathogenic features of psoriatic inflammation in obese and lean mice without causing adipose tissue destruction or systemic increase of inflammatory mediators.

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 GSE246074_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 PRJNA1031230 and SRA study SRP468010. Searching any of these in the dataset finder brings you back here.
