ACOX2 and isolated hemihyperplasia: Firstly, we evaluated genes related to FAO in the livers from control and IH mice (Figure 4A) in an attempt to characterize this process in IH conditions, finding that hepatic levels of genes involved in both mitochondrial (Ppargc1a, Pparg, Cpt1b, and Cpt2) and peroxisomal β-oxidation (Acox2, Ehhadh), as well as cytochrome ω-oxidation (Cyp4a10), were significantly reduced in IH mice compared to control animals (Figure 4B).
