Functional experiments demonstrated that miR-34c could reverse the oncogenic function of lncRNA DANCR (differentiation antagonizing non-protein coding RNA) in retinoblastoma tumorigenesis (Wang et al., 2018), and that miR-34c acts as tumor suppressor in uveal melanoma cell proliferation and migration through the down regulation of multiple targets (Dong and Lou, 2012). The gene discussed is DANCR; the disease is neoplasm.
