CXCR2 and hepatocellular carcinoma: To investigate the role of miR-940 in the malignant behavior of HCC, our data indicated that lower expression of miR-940 was evaluated to have an effect on the migration and invasion of HCC in vitro; we also showed that miR-940 overexpression suppressed cell migration and invasion and transcription of CXCR2 and thereby inhibit invasion and migration of HCC.
