CBL and leukemia: Additional miR-150 networks in immune cells include miR-150 repression of E3 ubiquitin-protein ligase CBL (CBL) and E3 SUMO-protein ligase EGR2 (EGR2) mRNAs-induced apoptosis in mixed-lineage leukemia cells [74] and repression of C-C chemokine receptor type 6 (CCR6) to limit cutaneous T-cell lymphoma invasion/metastasis [75].
