Study IDST002346
Study TitleLipidomics study of the cells defective in peroxisome division
Study SummaryProliferation of peroxisomes is accompanied by the growth and division of pre-existing peroxisomes. Pex11β induces the elongation of peroxisome membrane and then dynamin-like GTPase, DLP1, elicits the peroxisomal division. Nucleoside diphosphate kinase 3 (NME3) generates GTP for the DLP1 activity. Deficiencies of either of the factors induce abnormal morphology of peroxisomes. In this study, we assessed the phospholipid compositions in cells lacking each of the different division factors. In the fibroblasts from the patients deficient in DLP1, NME3, or Pex11β, docosahexaenoic acid (DHA, C22:6)-containing phospholipids were found to be decreased. Conversely, the levels of several fatty acids such as arachidonic acid (AA, C20:4) and oleic acid (C18:1) were elevated. Mouse embryonic fibroblasts from Drp1- and Pex11β-knockout mice also showed a decrease in the levels of phospholipids containing DHA and AA.
