Another such example is FECR1, a circRNA consisting of FLI1 4-2-3 exons, which is able to recruit TET1 DNA demethylase on the FLI1 promoter inducing DNA demethylation, thus promoting greater expression of FLI1 gene and consequently favoring the invasion of breast cancer cells [35]. Here, FLI1 is linked to breast carcinoma.
