RUNX2 and osteosarcoma: For instance, lncRNA DLX6-AS1 enhances osteosarcoma stemness via the regulation of miR-129-5p/DLK1 [56], promotes breast cancer progression via the regulation of the miR-505-3p/RUNX2 axis [57], cervical cancer progression by targeting the miR-16-5p/ARPP19 axis [58], and squamous cell carcinoma growth and invasion through the regulation of miR-376c [59].
