FASN and hydrops fetalis: To corroborate the histopathological analysis with quantitative data, the protein content of α-SMA and the expression of genes involved in HF, i.e., collagen type I, α 1(ColIa1) and heat shock protein 47 (Hsp47) were evaluated together with genes encoding for enzymes involved in fatty acid metabolism, i.e., fatty acid synthase (FASN) and carnitine palmitoyltransferase 1a (Cpt1a).
