  Optic atrophy 1 (OPA1), a GTPase at the inner mitochondrial membrane involved in regulating mitochondrial fusion, stability, and energy output, is known to be crucial for neural development: Opa1 heterozygous mice show abnormal brain development, and inactivating mutations in OPA1 are linked to human neurological disorders. Here, we used genetically modified human embryonic and patient-derived induced pluripotent stem cells and reveal that OPA1 haploinsufficiency leads to aberrant nuclear DNA methylation and significantly alters the transcriptional circuitry in neural progenitor cells (NPCs). For instance, expression of the forkhead box G1 transcription factor, which is needed for GABAergic neuronal development, is repressed in OPA1+/− NPCs. Supporting this finding, OPA1+/− NPCs cannot give rise to GABAergic interneurons, whereas formation of glutamatergic neurons is not affected. Taken together, our data reveal that OPA1 controls nuclear DNA methylation and expression of key transcription factors needed for proper neural cell specification.

DNMT3B deficiency alters mitochondrial biogenesis and α‐ketoglutarate levels in human embryonic stem cells. Stem Cells. ISSN 1066-5099. 38(11), p. 1409–1422. doi: 10.1002/stem.3256.

  Embryonic stem cell renewal and differentiation is regulated by metabolites that serve as cofactors for epigenetic enzymes. An increase of α‐ketoglutarate (α‐KG), a cofactor for histone and DNA demethylases, triggers multilineage differentiation in human embryonic stem cells (hESCs). To gain further insight into how the metabolic fluxes in pluripotent stem cells can be influenced by inactivating mutations in epigenetic enzymes, we generated hESCs deficient for de novo DNA methyltransferases (DNMTs) 3A and 3B. Our data reveal a bidirectional dependence between DNMT3B and α‐KG levels: a‐KG is significantly upregulated in cells deficient for DNMT3B, while DNMT3B expression is downregulated in hESCs treated with α‐KG. In addition, DNMT3B null hESCs exhibit a disturbed mitochondrial fission and fusion balance and a switch from glycolysis to oxidative phosphorylation. Taken together, our data reveal a novel link between DNMT3B and the metabolic flux of hESCs.
