In the Her2-enriched subtype, fibroblast migration and extracellular matrix disassembly were overrepresented in low-SETD7 tumours, from which the genes MMP7 (q-value = 3.25−02, log2FC = −1.32), KLK5 (q-value = 6.67−03, log2FC = −1.85), and KLK7 (q-value = 8.63−03, log2FC = −2.31) were strongly regulated (|log2FC| > 1). This evidence concerns the gene MMP7 and neoplasm.
