ABCB9 and hepatocellular carcinoma: Furthermore, a previously published paper on non-small-cell lung cancer (NSCLC) confirms an association between miR-31-5p and the lysosomally bound transporter ABCB9 [22], which prompted an investigation as to whether miR-31-5p may modulate ABCB9 expression in HCC cells and consequently regulate OXA transport across the lysosomal membrane.
