In order to identify which pathways might be associated with the expression of SLCO4A1, eight ovarian cancer cell lines with the highest (median 1,420 read counts) and eight cancer cell lines with the lowest SLCO4A1 expression levels (median 18 read counts) (p = 0.001) were selected to perform the gene set enrichment analysis (GSEA). This evidence concerns the gene SLCO4A1 and ovarian cancer.
