The miniature poodle with progressive rod-cone degeneration (prcd) is a model for human retinitis pigmentosa (RP). Since previous studies from several laboratories have shown abnormalities in plasma lipids in human RP, we examined the plasma lipids of prcd-affected animals. Fasting blood was drawn on three separate occasions from affected and control miniature poodles and on one occasion from normal Irish setters and those affected with a different inherited retinal degeneration (rod-cone dysplasia). Plasma phospholipids from prcd-affected animals had significantly lower levels of docosahexaenoic acid (22:6 omega 3) and cholesterol, compared to control miniature poodles. No differences were observed in plasma levels of phospholipids, vitamin E, or vitamin A, and no lipid differences were found between control and affected Irish setters. The ratios of 22:5 omega 3 to 22:6 omega 3 and of 22:4 omega 6 to 22:5 omega 6 were significantly elevated in prcd-affected poodles compared to controls. Since the conversion of 22:5 omega 3 to 22:6 omega 3 and of 22:4 omega 6 to 22:5 omega 6 is catalysed by a delta 4-desaturase, these results are consistent with a defect in desaturase activity in the prcd-affected poodle.
