ABCC1 and hepatocellular carcinoma: To further elucidate the role of miR-142-3p and its target genes in drug resistance, we transiently transfected miR-142-3p, siYES1 #7, or siTWF1 #5 (or relevant controls) into multiple HCC cell lines and analyzed the expression of drug resistance-associated genes MAP4K3 and ABCC1.
