Core Tip
Core tip: We found that (1) HULC expression was higher in serum exosomes of patients with HCC than in those of healthy controls, and higher in liver cancer tissues than in tumor adjacent tissues; (2) HULC expression in serum exosomes and liver cancer tissues were correlated with the TNM classification, and HULC expression in tissues was correlated with that in serum exosomes; (3) Increased HULC expression was associated with increased proliferation and invasion and reduced apoptosis of HCC cells; and (4) HULC repressed miR-372-3p expression, and miR-372-3p could directly bind both HULC and Rab11a. Furthermore, the HULC/ miR-372-3p /Rab11a axis promoted the secretion of exosomes from HCC cells.
