We performed hierarchical clustering of ROR1 with 24 EMT-related genes including the Hippo signaling pathway genes from the MSigDB database [27] along with WNT5a, BMI1, BCL2, and GLI1 prompted by associations noted in prior studies on breast cancer or CLL [25, 28–30]. This evidence concerns the gene BMI1 and B-cell chronic lymphocytic leukemia.
