The results showed that the mRNA expressions of NNMT, CAMK1D, CACNB1, GNMT, and ISYNA1 were significantly increased in IUGR piglets, whereas the mRNA expressions of CD38, BST1, CYP2C, FADS2, PTGS1, ELOVL2, ACOT7, GALM, PHGDH, PSAT1, PSPH, BHMT, DMGDH, and DNMT1 were significantly increased in the NBW group (Figure 6a). Here, ACOT7 is linked to fetal growth restriction.
