Summary (written by the submitters)

Full title: Cancer Associated Fibroblasts are activated in incipient neoplasia to orchestrate tumor promoting inflammation in an NF-κB-dependent manner. Cancer Associated Fibroblasts (CAFs) support tumorigenesis by stimulating angiogenesis, cancer cell proliferation, and invasion. We demonstrate that CAFs also mediate tumor-enhancing inflammation.

Using a mouse model of squamous skin cancer, we found a pro-inflammatory gene signature in CAFs isolated from dysplastic skin. This signature was also evident in CAFs from skin as well as mammary and pancreatic tumors in mice, and in human cancer. Surprisingly, the inflammatory signature was already activated in CAFs isolated from the incipient hyperplastic stage in multistep tumorigenesis. CAFs from this pathway functioned to promote macrophage recruitment, neovascularization and tumor growth in vivo, activities abolished when NF-κB signaling was inhibited. Additionally, we show that normal dermal fibroblasts can be “educated” by carcinoma cells to express pro-inflammatory genes.

3 · The original raw files

Whole study · RAW.tar

Everything the authors deposited as one archive (GSE17817_RAW.tar), including the raw array or instrument files. Can be large; the picker in step 2 takes just the samples you need.

What the files usually look like: For arrays the series matrix is normally the normalised expression table you want; the raw array files (CEL and similar) are in the RAW.tar.

Also filed as BioProject PRJNA120031. Searching any of these in the dataset finder brings you back here.
