STAT1 is a Central Node of Tumor Stimulated Stromal Signature. A,
Bright field (left) and fluorescent (right) images of ZsGreen PNA.Met1 xenograft
tumor and tumor associated gland (TAG). Dashed line indicates tumor-adjacent
tissue extracted for RNA-sequencing. B, Clustering analysis showing
the top DE genes in control and TAG groups. C, Cleveland plot of
gene set enrichment analysis (GSEA) from all DEGs (p < 0.05, q < 0.25)
with curated gene sets (C2) from the Molecular Signature Database (MSigDB).
D, Heat map of top 42 DEGs (FDR p < 0.05) from meta-analysis
of Zhang_RNA-seq with GSE14548 and GSE26910. E, Chord diagram of 15
meta-genes (red line) shared among all three datasets (Zhang_RNAseq, GSE14548,
and GSE26910). F, Nodal network generated from the 15 meta-gene
signature showing the top three ranked nodes. G, Representative
images of IHC staining for STAT1 in control (left) and TAG (right).
