Title	FASN-dependent de novo lipogenesis is required for brain development
Description	Fate and behaviour of neural progenitor cells is tightly regulated during mammalian brain development. Metabolic pathways, such as glycolysis and oxidative phosphorylation, that are required for supplying energy and providing molecular building blocks to generate cells, govern progenitor function. However, the role of de novo lipogenesis, which is the conversion of glucose into fatty acids through the multi-enzyme protein fatty acid synthase (FASN), for brain development remains unknown. Using Emx1Cre-mediated, tissue-specific deletion of Fasn in the mouse embryonic telencephalon, we show that loss of FASN causes severe microcephaly, largely due to altered polarity of apical, radial glia progenitors (APs) and reduced progenitor proliferation. Further, genetic deletion and pharmacological inhibition of FASN in human embryonic stem cell (ESC)-derived forebrain organoids identifies a conserved role of FASN-dependent lipogenesis for radial glia cell polarity and progenitor expansion in the developing human forebrain. Thus, our data establish a role of de novo lipogenesis for mouse and human brain development and identify a link between progenitor cell polarity and lipid metabolism.
