英文摘要 | Histone methyltransferases play a critical role in early human development, whereas their roles and precise mechanisms are less understood. SET and MYND domain-containing protein 2 (SMYD2) is a histone lysine methyltransferase induced during early differentiation of human embryonic stem cells (hESCs), but little is known about its function in undifferentiated hESCs and in their early lineage fate decision as well as underlying mechanisms. Here, we explored the role of SMYD2 in the self-renewal and mesendodermal lineage commitment of hESCs. We demonstrated that the expression of SMYD2 was significantly enhanced during mesendodermal but not neuroectodermal differentiation of hESCs. SMYD2 knockout (SMYD2(-/-)) did not affect self-renewal and early neuroectodermal differentiation of hESCs, whereas it blocked the mesendodermal lineage commitment. This phenotype was rescued by reintroduction of SMYD2 into the SMYD2(-/-) hESCs. Mechanistically, the bindings of SMYD2 at the promoter regions of critical mesendodermal transcription factor genes, namely, brachyury (T), eomesodermin (EOMES), mix paired-like homeobox (MIXL1), and goosecoid homeobox (GSC) were significantly enhanced during mesendodermal differentiation of SMYD2(+/+) hESCs but totally suppressed in SMYD2(-/-) ones. Concomitantly, such a suppression was associated with the remarkable reduction of methylation at histone 3 lysine 4 and lysine 36 but not at histone 4 lysine 20 globally and specifically on the promoter regions of mesendodermal genes, namely, T, EOMES, MIXL1, and GSC. These results reveal that the histone methyltransferase SMYD2 is dispensable in the undifferentiated hESCs and the early neuroectodermal differentiation, but it promotes the mesendodermal differentiation of hESCs through the epigenetic control of critical genes to mesendodermal lineage commitment.
