To investigate whether PD-L1-mediated tumor cell growth is accompanied by dysregulated miRNAs, we selected nine miRNAs (miR-29a-3p, miR-29b-3p, miR-21-5p, miR-125b-5p, miR-19a-3p, miR-155-5p, miR-199a-5p, miR-200b-3p, and miR-9-3p) that participate in tumor invasion and metastasis. Here, CD274 is linked to neoplasm.
