Analysis of GBmap [41], publicly available single-cell RNA sequencing data from 338,564 cells of 110 GBM patients, revealed that THOC1 expression is highest in Radial Glia (RG), while the coexpression of SIN3A and THOC1 is highest in the oligodendrocyte progenitor cell-like population (Figs. 4F-H). Here, SIN3A is linked to glioblastoma.
