To confirm this result, we further examined the gene set of 239 ECM-related genes in publicly available TCGA gene expression data of ovarian cancer, and we observed highly consistent correlation that the expressions of those genes were positively related to a platinum-sensitive phenotype of ovarian cancer (NES = 2.466, FDR q value <0.0001; Figure S3). This evidence concerns the gene MMRN1 and ovarian carcinoma.
