Abstract
. Circ_0061395 and SPOCK1 were significantly expressed in liver cancer tissues and cells. Silencing circ_0061395 reduced the proliferation, migration, invasion, tube formation and tumor spheroid formation rate of Huh-7 and SNU-387 cells. MiR-1182 was a target of circ_0061395. Silencing circ_0061395 inhibited the malignant behavior of HCC cells by releasing miR-1182. In addition, SPOCK1 was the target of miR-1182. Overexpression of SPOCK1 partially restored the inhibitory effect of miR-1182 on cell proliferation. Animal experiments confirmed the anti-tumor effect of silence circ_0061395. Circ_0061395 induced the changes of the expression of SPOCK1 by regulating miR-1182, thereby mediating the process of HCC, and at least partially promoting the development of HCC cells, providing a novel targeted therapy for HCC.
