CASP3 and hepatocellular carcinoma: Finally, the expression of miR-24-3p, miR-221-3p, caspase-8, and caspase-3 was determined in tissue samples; Figures 9A–D showed that miR-24-3p and miR-221-3p were significantly upregulated, whereas caspase-8 and caspase-3 were downregulated in HCC tissues compared with non-cancerous tissues.
