Summary (written by the submitters)
Polycystic ovary syndrome (PCOS) is a female endocrine disorder characterized by hyperandrogenism, chronic anovulation, and polycystic ovaries. PCOS is often accompanied by symptoms such as insulin resistance, abdominal obesity, and chronic inflammation. Adipose tissue is a crucial endocrine organ involved in metabolic disorders. Metabolic issues and chronic inflammation in PCOS are linked to dysfunctional adipose tissue.

Mesenchymal progenitor cells (MPCs) are the precursor cells of adipocytes and can regulate the immune system. In this study, we used induced pluripotent stem cells (iPSCs) from patients with PCOS to derive MPCs and compare the transcriptome profiles between PCOS and HC iPSC-derived MPCs. We also challenged iPSC-derived MPCs with testosterone to assess the impact of androgen on MPCs. We found that 1026 genes differed between PCOS and HC iPSC-derived MPCs. Gene set enrichment analysis showed adipogenesis and metabolic function were reduced, but the inflammatory response was raised in PCOS iPSC-derived MPCs. The critical signals for early adipogenesis, including TGFβ, BMP, WNT, and CEBPA, differed between PCOS and HC iPSC-derived MPCs. After adipogenic induction, mature adipocytes were lower in PCOS iPSC-derived MPCs than HC. Lipolysis, the process involved in fat metabolism, was lower in adipocytes derived from PCOS MPCs than in HC. The testosterone treatment results indicated that genes related to oxidative phosphorylation and fatty acid metabolism were upregulated in HC iPSC-derived MPCs but downregulated in PCOS iPSC-derived MPCs. Short-term androgen stimulation may benefit body functions in HC. The impact of testosterone varied among individuals with HC and PCOS, possibly because of a genetic tendency towards PCOS. This study explains important factors that help us understand PCOS.

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 GSE267287_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 PRJNA1110998 and SRA study SRP507283. Searching any of these in the dataset finder brings you back here.

Study design
4 × C vs 4 × P

Supports a between-group comparison across 8 samples.

How we read this: 2 replicated groups read from 14 sample titles; they account for 8 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.
