    Description: Cancer cells have been at the centre of cell metabolism research, but the metabolism of stromal and immune cells has received less attention. Nonetheless, these cells influence the progression of malignant, inflammatory and metabolic disorders. Here we discuss the metabolic adaptations of stromal and immune cells in health and disease, and highlight how metabolism determines their differentiation and function.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ghesquiere, Bart -- Wong, Brian W -- Kuchnio, Anna -- Carmeliet, Peter -- England -- Nature. 2014 Jul 10;511(7508):167-76. doi: 10.1038/nature13312.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉1] Laboratory of Angiogenesis and Neurovascular Link, Vesalius Research Center, Department of Oncology, University of Leuven, Leuven B-3000, Belgium [2] Laboratory of Angiogenesis and Neurovascular Link, Vesalius Research Center, VIB, Leuven B-3000, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/25008522" target="_blank"〉PubMed〈/a〉

    Description: The metabolism of endothelial cells during vessel sprouting remains poorly studied. Here we report that endothelial loss of CPT1A, a rate-limiting enzyme of fatty acid oxidation (FAO), causes vascular sprouting defects due to impaired proliferation, not migration, of human and murine endothelial cells. Reduction of FAO in endothelial cells did not cause energy depletion or disturb redox homeostasis, but impaired de novo nucleotide synthesis for DNA replication. Isotope labelling studies in control endothelial cells showed that fatty acid carbons substantially replenished the Krebs cycle, and were incorporated into aspartate (a nucleotide precursor), uridine monophosphate (a precursor of pyrimidine nucleoside triphosphates) and DNA. CPT1A silencing reduced these processes and depleted endothelial cell stores of aspartate and deoxyribonucleoside triphosphates. Acetate (metabolized to acetyl-CoA, thereby substituting for the depleted FAO-derived acetyl-CoA) or a nucleoside mix rescued the phenotype of CPT1A-silenced endothelial cells. Finally, CPT1 blockade inhibited pathological ocular angiogenesis in mice, suggesting a novel strategy for blocking angiogenesis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4413024/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4413024/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schoors, Sandra -- Bruning, Ulrike -- Missiaen, Rindert -- Queiroz, Karla C S -- Borgers, Gitte -- Elia, Ilaria -- Zecchin, Annalisa -- Cantelmo, Anna Rita -- Christen, Stefan -- Goveia, Jermaine -- Heggermont, Ward -- Godde, Lucica -- Vinckier, Stefan -- Van Veldhoven, Paul P -- Eelen, Guy -- Schoonjans, Luc -- Gerhardt, Holger -- Dewerchin, Mieke -- Baes, Myriam -- De Bock, Katrien -- Ghesquiere, Bart -- Lunt, Sophia Y -- Fendt, Sarah-Maria -- Carmeliet, Peter -- 269073/European Research Council/International -- England -- Nature. 2015 Apr 9;520(7546):192-7. doi: 10.1038/nature14362.
