Functions of specific circular RNAs (circRNAs) in melanoma pathogenesis. Schematic diagram of circRNAs involved in melanoma progression. Red and blue color indicated the oncogenic and suppressive functions of circRNAs in different biological processes involved in melanoma progression, respectively. Up and down arrows indicated the activation and inhibition of physiological processes in melanoma pathogenesis, respectively (Bian et al., 2018; Ju et al., 2018; Luan et al., 2018; Wang Q. et al., 2018; Lin et al., 2019; Shang et al., 2019; Zou et al., 2019; Chen J. et al., 2020; Chen Z. et al., 2020; Hanniford et al., 2020; Jin et al., 2020; Lu and Li, 2020; Lu et al., 2020; Qian et al., 2020; Tian et al., 2020; Wei et al., 2020; Liu et al., 2021; Yin et al., 2021).
