It has proved that SNHG7 was able to regulate osteosarcoma (OS) cell vitality, migration, and invasion by activating sponging miR-34a, which targeted and suppressed the epithelial-mesenchymal transition (EMT) through the TGF-β/SMAD4 signaling pathway [35]. The gene discussed is TGFB1; the disease is osteosarcoma.
