CD274 and diffuse large B-cell lymphoma: Other studies also reported that lncRNA LINC00473 sponged miR-195-5p to enhance the expression of PD-L1 in prostate cancer (77), while lncRNA MALAT1 regulated tumor migration and immune evasion by modulating the miR-195/PD-L1 axis in diffuse large B-cell lymphoma (51) and the miR-200a-3p/PD-L1 axis in lung cancer (69), respectively.
