A study in human brain cancer demonstrated that the circFBXW7 functions as a tumor suppressor, where its expression inhibits cell progression, migration, and tumor formation [Di Agostino et al. DOI:10.3389/fcell.2020.00389]. Further research confirmed its coding potential, showing the translated peptide FBXW7-185aa reduces the half-life of c-Myc and inhibits cell cycle progression [Sema Misir et al. DOI:10.1038/s41418-022-00948-7]. The peptide FBXW7-185aa, which originates from the circFBXW7, inhibits cell cycle progression [Misir et al. DOI:10.1038/s41418-022-00948-7].
