Over-expression of miR-92b in HCC cell lines increased their motility, but, more interestingly, transfection of miR-92b in NK92 cells inhibited their cytotoxicity against HCC cells at least in part by downregulating CD69, similarly to what is observed when NK92 cells are treated with HCC-derived exosomes, which are enriched for miR-92b [53]. The gene discussed is CD69; the disease is hepatocellular carcinoma.
