For instance, circRNA nucleolar and coiled-body phosphoprotein 1, circRNA formin 1, circ-0016068, circ_0088233 and circ0005276 are all upregulated in prostate cancer and promote the development of prostate cancer (Feng et al., 2019; Chen et al., 2020; Deng et al., 2020; Li et al., 2020; Shan et al., 2020).
