SMAD3 and glioma: Therefore, we assumed that CEBPB might regulate TGFBR2 and SMAD3 through TGF-β1/SMAD3 signaling pathway in glioma, and CEBPB could also affect metastasis of glioma by regulating TCF12. However, in our study, TGFB1 and SMAD3 were not significantly expressed, which might due to the relatively short time for CEBPB silencing.
