SLC2A4 and hydrops fetalis: After 4 weeks of drug treatment in HF model rats, EMPG showed the same lipid metabolism pathway proteins (PPARα, RXRα, and CPT1α) and energy metabolism pathway proteins (AMPKα and sirt1) as FF, but only EMPG showed a significant decrease in MRGlu, inhibition of glycolytic pathway protein (GLUT 4) expression, and decreased cardiac fibrosis in HF rats.
