Progressing gestation in both CD and GDM dams significantly decreased protein and mRNA markers of hepatic mitochondrial biogenesis (Pgc1-α, Tfam), autophagy (Atg5, Sqstm1), mitophagy (Pink1, Bnip3) and lipid handling (Ampk, pAMPK/AMPK, FAS, ACC, pACC, Mttp) with a main effect for time (P<0.05). Here, PPARGC1A is linked to gestational diabetes.
