SNHG12 and osteosarcoma: SNHG12 is higher in Dox-resistant osteosarcoma cells than in sensitive cells and correlates with lower patients’ survival: specifically, SNHG12 induces resistance by up-regulating the mir320a/myeloid cell leukemia 1 (MCL1) axis that protects from the apoptosis induced by Dox [13].
