MEG3 and hepatocellular carcinoma: CNC@CB[8]@PGEA condensed pc3.0-miR-101 and pc3.0-MEG3 into nanocomplexes with a diameter of about 200 nm (Fig. 9b-II) and implemented the co-transport of short and long ncRNAs in vivo to suppress the growth of hepatocellular carcinoma (HCC) tumor (Fig. 9b-III) without inducing obvious toxicity.
