The zebrafish is an animal model in ophthalmic diseases : Fleck corneal dystrophy and Schorderet-Munier syndrome

RAPPORT DE SYNTHÈSE : Pip5k3 : Pip5k3 is a kinase responsible for fleck corneal dystrophy when mutated. It is a well conserved gene that has only been characterized in human and mouse. Characterization of pip5k3 in zebrafish was necessary before using it as a model. The protein is 70 % similar to the human homologue. The full coding sequence encompasses 6303 by and presented four isoforms. They were differentially expressed during development. All the analyzed organs of the adult zebrafish expressed pip5k3. The adult eye expressed pip5k3 in the cornea, lens, ganglion cell layer (GCL), inner nuclear layer (INL) and outer limiting membrane (OLM). During development, pip5k3 was first uniformly expressed before to be restricted to the head region and to the somites. The expression of pip5k3 in the cornea of the larval eye could make possible the study of fleck corneal dystrophy on this animal. NkxS-3 : NKXS-3 is a transcription factor responsible for a new oculo-auricular syndrome in human when mutated. This recessive disorder is characterized by defects in ear lobule and multiple defects in eye, including microphthalmia and cataract. During development, the zebrafish expressed nkx5-3 in the lens, in the anterior retina and in otic vesicles. Knockdown experiments partially phenocopied the human disease. Microphthalmia and cataract were reproduced, but zebrafish showed also defects in the cartilage of the jaw associated with a microcephaly and fins abnormalities. The retinal cell differentiation was delayed, possibly linked with the delayed expression of at`h5 and crx also observed in morphants. Shh, a regulator of ath5, was normally expressed in morphant. Overexpression of nkx5-3 lead to an anophthalmia, suggesting a role at the early organogenesis of the eye. All the phenotypes observed in morphants and embryos overexpressing nkx5-3 suggest a potential involvement of the FGF and hedgehog signaling pathways.

Effect of fructose overfeeding and fish oil administration on hepatic de novo lipogenesis and insulin sensitivity in healthy men.

High-fructose diet stimulates hepatic de novo lipogenesis (DNL) and causes hypertriglyceridemia and insulin resistance in rodents. Fructose-induced insulin resistance may be secondary to alterations of lipid metabolism. In contrast, fish oil supplementation decreases triglycerides and may improve insulin resistance. Therefore, we studied the effect of high-fructose diet and fish oil on DNL and VLDL triglycerides and their impact on insulin resistance. Seven normal men were studied on four occasions: after fish oil (7.2 g/day) for 28 days; a 6-day high-fructose diet (corresponding to an extra 25% of total calories); fish oil plus high-fructose diet; and control conditions. Following each condition, fasting fractional DNL and endogenous glucose production (EGP) were evaluated using [1-13C]sodium acetate and 6,6-2H2 glucose and a two-step hyperinsulinemic-euglycemic clamp was performed to assess insulin sensitivity. High-fructose diet significantly increased fasting glycemia (7 +/- 2%), triglycerides (79 +/- 22%), fractional DNL (sixfold), and EGP (14 +/- 3%, all P < 0.05). It also impaired insulin-induced suppression of adipose tissue lipolysis and EGP (P < 0.05) but had no effect on whole- body insulin-mediated glucose disposal. Fish oil significantly decreased triglycerides (37%, P < 0.05) after high-fructose diet compared with high-fructose diet without fish oil and tended to reduce DNL but had no other significant effect. In conclusion, high-fructose diet induced dyslipidemia and hepatic and adipose tissue insulin resistance. Fish oil reversed dyslipidemia but not insulin resistance.
