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.

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)
Scaffold protein IQGAP3 mediates assembly of multiprotein complexes, orchestrating intracellular signaling pathways. Earlier we have found it to be overexpressed in lesional psoriatic skin. IQGAP3 is involved in cell proliferation and chemokine signaling that are key processes in psoriasis, so we decided to investigate the molecular basis of its role in psoriatic phenotype of keratinocytes.

Transcriptome profiling of HaCaT keratinocytes allowed us to identify a wide range of psoriasis-associated pathways to be altered in IQGAP3-knockdown cells. NFkB signaling, EGFR signaling, p38/MAPK and ERK1/ERK2 activation, lipid metabolism and cytokine production as well as the response to the inflammatory cytokine stimulation were altered in the knockdown cells. Real-time analysis of cell growth revealed the alterations of proliferation and wound healing. The balance between proliferation and apoptosis of skin cells was altered, as well as the skin barrier functions and the production of IL-6 and IFNg. However, the diversity of the pathway alterations in the knockdown cells led us to the conclusion that IQGAP3 may not be the best target for the therapeutic inhibition to normalize the phenotype of keratinocytes in psoriasis.

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 GSE248548_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 PRJNA1044763 and SRA study SRP473997. Searching any of these in the dataset finder brings you back here.
