In GSE40595, we performed gene set enrichment analysis (GSEA) in 31 microdissected ovarian tumor stromal samples and identified that the “ECM-RECEPTOR-INTEREACTION” as a significantly enriched signature among the gene sets positively correlated with MARCKS expression (NES=1.69, FDR q=0.019) (Figure 4A). Here, MARCKS is linked to ovarian neoplasm.
