ZC3H13 and cutaneous melanoma: From this, three important m6A RNA methylation regulators were selected, which included ELF3, ZC3H13, WTAP, multivariate Cox regression (Figure 4C) indicated that “ELF3” and “ZC3H13” served as risk factors that were closely related to poor survival, while “WTAP” was a protective factor among cutaneous melanoma patients.
