CD274 and lung carcinoma: Lnc01140 elevated programmed death-ligand 1 (PD-L1) and c-Myc expression by repressing multiple microRNAs including miR-377-3 p and miR-155-5 p. In vivo assay, downregulation of Lnc01140 repressed the growth of subcutaneous lung cancer xenografts by inhibition of PD-L1 expression (40).
