Thrilled to share a new study from the lab revealing an H3K18ub-H3K9me3 crosstalk mechanism, roles for UHRF1 and its E3 ligase activity in regulating a hierarchy of repressive histone methylation signaling, and a strategy for targeting SUV39H1/H2 to improve DNMT1 inhibitor efficacy! #epigenetics
Liu et al. report that DNMT1 inhibition causes transient accumulation of hemi-methylated
DNA at CpG islands, which stimulates UHRF1-mediated H3K18ub. This enhances SUV39H1/H2
activity, nucleates new H...
