| abstractText | Maternal diabetes is known to adversely influence brain development in offspring. Here, we provide evidence that this involves the circulating metabolite methylglyoxal, which is increased in diabetes, and its detoxifying enzyme, glyoxalase 1 (Glo1), which when mutated is associated with neurodevelopmental disorders. Specifically, when Glo1 levels were decreased in embryonic mouse cortical neural precursor cells (NPCs), this led to premature neurogenesis and NPC depletion embryonically and long-term alterations in cortical neurons postnatally. Increased circulating maternal methylglyoxal caused similar changes in embryonic cortical precursors and neurons and long-lasting changes in cortical neurons and NPCs in adult offspring. Depletion of embryonic and adult NPCs was also observed in murine offspring exposed to a maternal diabetic environment. Thus, the Glo1-methylglyoxal pathway integrates maternal and NPC metabolism to regulate neural development, and perturbations in this pathway lead to long-lasting alterations in adult neurons and NPC pools. |
