lncRNA TUG1 promoted the proliferation, migration, and invasion of hepatoma cells by activating the JAK2/STAT3 pathway, upregulating the expression of AURKA, interacting with miR-216B-5p and inhibiting apoptosis by activating DLX2, or by down-regulating miR-142-3p to regulate the miR-29c-3p/COL1A1 axis. This evidence concerns the gene COL1A1 and hepatocellular carcinoma.
