Abstract
• Cyp2j4 deletion in rats offers a simplified genetic landscape as opposed to the mice locus, which is under significant allelic expansion.
• Under different metabolic stresses (aging, cafeteria diet), Cyp2j4−/− rats show an accelerated adipogenesis, which progress towards adipocyte dysfunction.
• Adipocyte dysfunction in Cyp2j4−/− rats under cafeteria diet (CAF) is characterised by down-regulation of white adipose tissue (WAT) PPARγ and C/EBPα, adipocyte hypertrophy and extracellular matrix remodeling.
• Cyp2j4−/− rats treated with CAF display exacerbated weight gain, insulin resistance, hepatic lipid accumulation and dysregulated gluconeogenesis.
• Cyp2j4−/− rats display alternative arachidonic acid pathway usage in their adipose tissue upon CAF and aging.
