TTN-AS1 promotes proliferation, migration, invasion, and epithelial-mesenchymal transformation (EMT) of hepatocellular carcinoma cells by regulating the miR-139-5p/ sparc/osteonectin, cwcv, and kazal-like domains proteoglycan 1 (SPOCK1) axis [39]. The gene discussed is SPOCK1; the disease is hepatocellular carcinoma.
