PTK2 and hepatocellular carcinoma: In hepatocellular carcinoma 35, DARS-AS1 up-regulates CKAP2 by binding to miR-3200-5p, thereby activating the FAK-ERK pathway and promoting HCC proliferation and metastasis, and DARS-AS1 is also reported to promote HCC cell proliferation and inhibits apoptosis through inhibiting the function of PACT 46.
