There is growing evidence indicating the different roles of natural UHRF1 inhibitory protein STELLA in mouse-derived cells from its human ortholog. Here, the authors report the differences of hSTELLA versus mSTELLA in inhibiting the maintenance or de novo DNA methylation functions of UHRF1 in human cancer cells, and lipid nanoparticle-delivered mSTELLA reversing cancer-specific DNA hypermethylation thereby impairing colorectal cancer tumorigenicity.
