CD274 and neoplasm: RP11-424C20.2 may act as a ceRNA in thymomas (a tumor originating from the epithelial cells of the thymus), increasing the expression of its parental gene ubiquitin-like protein containing PHD and RING finger domains 1 (UHRF1) via sponging miR-378a-3p, and modulating IFN-γ-mediated CLTA-4 and PD-L1 activity [151].
