Abstract |
(Dihydro) ceramide synthase 2 (cers2, formerly called lass2) is the most abundantly expressed member of the ceramide synthase gene family, which includes six isoforms in mice. CERS2 activity has been reported to be specific toward very long fatty acid residues (C22–C24). In order to study the biological role of CERS2, we have inactivated its coding region in transgenic mice using gene-trapped embryonic stem cells that express lacZ reporter DNA under control of the cers2 promoter. The resulting mice lack ceramide synthase activity toward C24: 1 in the brain as well as the liver and show only very low activity toward C18: 0–C22: 0 in liver and reduced activity toward C22: 0 residues in the brain. In addition, these mice exhibit strongly reduced levels of ceramide species with very long fatty acid residues (≥ C22) in the liver, kidney, and brain. From early adulthood on, myelin stainability is progressively lost … |
