Summary |
Epigenetic regulation of chromatin states is thought to control gene expression programs during lineage specification. However, the roles of repressive histone modifications such as trimethylated histone lysine 20 (H4K20me3) in development and genome stability are largely unknown. Here, we show that depletion of SMYD5, a H4K20me3 methyltransferase, leads to decreased H4K20me3 and H3K9me3 ChIP-Seq levels, and de-repression of endogenous LTR/LINE elements during differentiation. SMYD5 depletion results in chromosomal aberrations and the formation of transformed cells that exhibit decreased H4K20me3 and H3K9me3 levels and an expression signature consistent with multiple human cancers. Moreover, dysregulated gene expression in SMYD5 cancer cells is associated with LTR/ERV elements and decreased H4K20me3. These findings implicate an important role for SMYD5 in maintaining chromosome integrity by regulating heterochromatin and repressing endogenous repetitive DNA elements during differentiation.
