MTTP and hydrops fetalis: Genes related to other pathways of lipid metabolism, including Ppara and Acox1 which mediate β-oxidation of fatty acid catabolism, Fatp1 which helps fatty acid transport, Dgat1 which mediates the esterification reaction of triglyceride synthesis, or Mttp which assists with lipoprotein assembly were not differentially expressed due to HF feeding or maternal choline supplementation (p > 0.05) (Figure 4a).
