Abnormalities have been reported previously in 4\u2010hydroxynonenal (HNE) levels in English setters with CCL. The purpose of this study was to examine the sources of HNE in neutrophil membranes and plasma of CCL dogs. The fatty acid composition of neutrophil phospholipids, i.e., phosphatidyl ethanolamine and phosphatidyl serine, was determined by gasliquid\u2010chromatography (GLC) since some polyunsaturated fatty acids (PUFA) are precursors of HNE. The copper catalyzed peroxidation of low density lipoprotein (LDL) was examined to determine the susceptibility of LDL from CCL dogs to peroxidation. The results indicated that a number of PUFA precursors of HNE decreased in affected and carrier neutrophil phospholipids, indicating that this source of HNE may be disease specific. The Cu<jats:sup>++<\/jats:sup> catalyzed formation of HNE from LDL demonstrated that carrier and normal LDL produced large amounts of HNE, while LDL from affected dogs required much higher concentrations of Cu<jats:sup>++<\/jats:sup> for maximal HNE production. These results provide additional support for the role of HNE in the pathogenetic events in NCL and support the view that lipid peroxidation may be an important contributor to the complex pathogenesis of the NCL. \u00a9 1995 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.1320570235","type":"journal-article","created":{"date-parts":[[2005,6,11]],"date-time":"2005-06-11T18:01:48Z","timestamp":1118512908000},"page":"290-293","source":"Crossref","is-referenced-by-count":7,"title":["Biosynthesis and metabolism of 4\u2010hydroxynonenal in canine ceroid\u2010lipofuscinosis"],"prefix":"10.1002","volume":"57","author":[{"given":"Aristotle N.","family":"Siakotos","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kathryn","family":"Schnippel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renee C.","family":"Lin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frederick J.
