Activités cytotoxiques et pro-oxydantes d'acides gras à très longue chaîne sur des oligodendrocytes murins sauvages et déficients en Abcd1 et Acox1 :…

X-ALD and P-NALD are two rare, peroxisomal metabolic and neurodegenerative diseases. ABCD1 and ACOX1 are known to be responsible for X-ALD and P-NALD, respectively. The actively demyelinating lesions in CNS, exhibited signs of oxidative stress and cell death. The accumulation of VLCFA in plasma and tissue is the biochemical common hallmark to both diseases. First, we characterized a murine oligodendrocytes cell line 158N to use it as a model. This 158N cell line which has characteristics of mature oligodendrocytes (expression of myelin proteins MOG, MBP, PLP), has also functional peroxisomes with Abcd1 and Acox1 proteins. Then, we studied the cytotoxic and pro-oxidative effects of VLCFA (C2…
Molecular basis of the effects of argan oil on mitochondrial and peroxisomal metabolism of the fatty acids and inflammation
2012
The objective of this thesis work was to explore the molecular basis of Argan Oil (AO) effects on the mitochondrial and peroxisomal lipid metabolism and to elucidate its anti-inflammatory potential. We thus showed, initially, that the artisanal method preparation preserved the antioxidant properties of AO preventing the oxidation of the ferulic acid, by contrast to AO of commercial origin. Then, the treatment by the AO or lipopolysaccharides (LPS) of human fibroblasts, the cellular model of pseudo-neonatal adrenoleukodystrophy (P-NALD), revealed for the AO that peroxisomes proliferation is independent from the activation of the nuclear receptor PPARα and the co-activator PGC-1α. On the othe…
