ZKSCAN1 and medulloblastoma: The seven circRNAs, FKBP8, SMARCA5, GLIS1, BACH1, ZKSCAN1, CDYL, and OGDH, with a reduced expression in medulloblastoma versus cerebellum, while their corresponding linear mRNAs do not follow this change of expression pattern (Figure 3C,D), were selected for further analysis.
