ABCG2 and hepatocellular carcinoma: Altered expression of lincRNA‐LVVDL in cells is related to increased expression of ABCG2,47 a member of ATP‐binding cassette (ABC) transporter superfamily involved in drug elimination of cancer cell.65, 66 Furthermore, overexpression of lincRNA‐LVVDL was also found in HCC cell‐derived exosomes, indicating that cancer cells maintain chemoresistance not only by eliminating chemodrug via exosomes but also by inducing molecular transfer.47
