Figure 1.Reduced protein levels of DNMT1 correlate with decreased global DNA methylation(A) DNMT1 and MAT2A protein levels normalized to protein levels in PD 38 cells. Averages of three biological replicates ± standard deviation. (B) Western blot images. (C) Cytosine extension assay showing average incorporation of radioactively labeled dCTP from three samples per PD level; error bars indicate standard.
