Modulation of peroxisomes abundance by argan oil and lipopolysaccharides in acyl-CoA oxidase 1-deficient fibroblasts

Pseudo-neonatal adrenoleukodystrophy (P-NALD) is a neurodegenerative disorder caused by acyl-CoA oxidase 1 (ACOX1) deficiency with subsequent impairment of peroxisomal fatty acid β-oxidation, accumulation of very long chain fatty acids (VLCFAs) and strong reduction in peroxisome abundance. Increase in peroxisome number has been previously suggested to improve peroxisomal disorders, and in this perspective, the present work was aimed at exploring whether modulation of peroxisomes abundance could be achieved in P-NALD fibroblasts. Here we showed that treatment with the natural Argan oil induced peroxisome proliferation in P-NALD fibroblasts. This induction was independent on activations of bo…
