TASL and oligodendroglioma: The expression levels of TASL were higher in isocitrate dehydrogenase (IDH)-wildtype (IDH-WT) than that in IDH-mutant (IDH-Mut) patients, in 1p/19q non-co-deletion than that in 1p/19q co-deletion patients, and in astrocytomas (A) than that in oligoastrocytomas (OA) and oligodendrogliomas (OD; Fig. 5C).
