Title	Increased lipid transport and de novo synthesis lead to dynamic lipidome remodeling and regulation of lipid-dependent kinases during megakaryopoiesis and proplatelet formation
Description	During megakaryopoiesis and consecutive platelet production, megakaryocytes undergo robust cellular morphological changes which are associated with the reprogramming of signaling pathways. Moreover, it can be assumed that lipid membrane composition and signaling are strongly modified. However, the knowledge of lipid alteration during megakaryopoiesis and which pathways are involved is still lacking. Here, we use a lipid-centric multiomics approach to create a quantitative map of the megakaryocyte lipidome during maturation and proplatelet formation. Our data reveal that megakaryocyte differentiation is driven by an increased fatty acyl import and de novo lipid synthesis, resulting in the modulation towards an anionic membrane phenotype. This phenotype and the upregulation of diacylglycerols highly correlate with the activation of lipid-dependent kinases such as PKC and BTK. Using inhibitors of fatty acid import and phospholipid synthesis proved to block membrane remodeling and kinase activation and directly reduced proplatelet formation. Altogether, this study provides a framework for understanding how membrane lipid remodeling during megakaryocyte differentiation impacts kinase signaling and proplatelet formation while providing a knowledge base to exploit megakaryopoiesis.
