In addition, the mRNA levels of PPARα target genes such as cluster of differentiation 36 (CD36), cytochrome P450 4a10 (CYP4a10), cytochrome P450 4a14 (CYP4a14), acyl-CoA oxidase (ACO) and stearoyl-CoA desaturase-1 (SCD1) were also significantly increased in HF+FME group compared to those in HF group. Here, KLK15 is linked to hydrops fetalis.
