CEBPB and non-small cell lung carcinoma: Additionally, transfection of C/EBPβ in cells overexpressing MIR503HG attenuated the suppressive impact of MIR503HG on NSCLC cell activity (Figures 2F,G and S2F,G), indicating that C/EBPβ might participate in the regulatory processes that are mediated by MIR503HG.
