We observed that both mRNA and protein levels of ASPP2 were significantly reduced after miR-30b-5p overexpression (Figures 7(a) and 7(c)), and conversely, the mRNA and protein levels of ASPP2 were increased by transfection of miR-30b-5p inhibitor in both MDA-MB-231 and HCC 1937 cells (Figures 7(b) and 7(d)). Here, TP53BP2 is linked to hepatocellular carcinoma.
