STAT1 and neoplasm: We also observed that Mettl3 or Mettl14 overexpression significantly attenuated DLL-enhanced Stat1 and Irf1 in 3LL tumor cells (Figures 6(a) and 6(b)), and MeRIP-qPCR results showed that Mettl3 or Mettl14 overexpression significantly enhanced the m6A methylation levels of Stat1 and Irf1 that were reduced by DLL treatment (Figure 6(c)).
