Compared with normal healthy rats, HF model rats showed a significant increase in MRGlu, and the expression of the lipid metabolism pathway proteins (PPARα, RXRα, CPT1α, and CD36) and the energy metabolism pathway proteins (AMPKα and sirt1) were significantly inhibited, while the expression of the glycolytic pathway protein (GLUT4) was enhanced. Here, CPT1A is linked to hydrops fetalis.
