To evaluate the correlation of PDHX with miR-27b using tissue expression data beyond that from our own lab, we devised an approach to compare PDHX and miR-27b expression by utilized TCGA expression data for PDHX and miR-27b and performed a correlation plot in luminal A and ER+ BC types (Fig. 7a, b; Additional file 3: Table S2). Here, PDHX is linked to breast cancer.
