Here we uncover that inducing naive human embryonic stem cells towards the trophectoderm lineage results in considerable metabolic rewiring, characterized by αKG accumulation. Elevated αKG levels potentiate the capacity of naive embryonic stem cells to specify towards the trophectoderm lineage. Moreover, increased αKG levels promote blastoid polarization and trophectoderm maturation. αKG supplementation does not affect global histone methylation levels; rather, it decreases acetyl-CoA availability, reduces histone acetyltransferase activity and weakens the pluripotency network.

Although NADPH is compartmentalized within the cytosol and mitochondria, the specific functions of mitochondrial NADPH remain largely unexplored.

The mitochondrial fatty acid synthesis (mtFAS) pathway utilizes NADPH for generating protein-bound acyl groups, including lipoic acid. By developing a mass-spectrometry-based method to assess mammalian mtFAS, we reveal that NADK2 is crucial for mtFAS activity. NADK2 deficiency impairs mtFAS-associated processes, leading to reduced cellular respiration and mitochondrial translation.
