D L3MBTL3, but neither L3MBTL3-Δ(1-64) nor L3MBTL3-Δ(SAM), leads to decreasing H3K4me2 at the proximal Notch-responsive element of HES1. ChIP analysis of H3K4me2 at the proximal Notch-responsive element of HES1 upon overexpression of LacZ control (Control), L3MBTL3, L3MBTL3-Δ(1-64) or L3MBTL3-Δ(SAM) in L3MBTL3 KO U87-MG cells. Shown are means ±s.d. of duplicate experiments measured twice each. P values were estimated via a one-way ANOVA on log-transformed data.Panels B, C and D: distance in bp relative to the TSS is indicated below the gene names. Chrom8 was used as negative control (NEG).
