LINC00942 and glioblastoma: In addition, we confirmed a markedly activated STAT3/P300 axis in Linc00942‐overexpressing GBM cells, TMZ‐resistant GBM cells, and MUT‐2 GBM cells (but not in MUT‐1 cells), suggesting that the interaction between Linc00942 and PKM2 plays a key role in activating the STAT3 pathway (Figure 4F; Figure S10E, Supporting Information).
