“…These activities were related to YAP activation. Several recent publications showed the role played by specific miRNA in controlling stemness in osteosarcoma, including miR29b and its target Spin1 [ 82 ] , miR34a [ 83 ] and the DNMT1/miR34a/Bcl2 axis [ 84 , 85 ] , TNF-α-miR155 signaling [ 86 ] , miR335 and its target POUF5 [ 87 ] , miR429 and its target Sox2 [ 88 ] , and the TGF-β/miR499a/SHKBP1 89 axis [ 89 , 90 ] . Very recently, leukemia inhibitory factor (LIF) was shown to belong to the IL-6 family of cytokines, similarly activating STAT-3, and was recently revealed as a super-enhancer-controlled regulator of CSC properties, confirming the role of STAT-3 transcription factor in the functional regulation of CSCs in osteosarcoma [ 91 ] .…”
