EET MN1-BEND2 express high mRNA levels of the ependymoma-associated genes FOXJ1, IGF2, CELSR1, RFX3, KCNJ5, TFF3 and YAP1 and relatively low levels of messages of canonical astrocyte marker genes such as OLIG2, GFAP, ALDH1L1, and S100 β [10, 31]. The gene discussed is YAP1; the disease is ependymoma.
