Changes in plasma lipoproteins and liver lipids in neonatal rats.
Transient increases in triglycerides and cholesterol were found in rat liver immediately after birth. Plasma VLDL and HDL increased after birth and reached a plateau after one week of life. The content of cholesterol ester was low at birth in all lipoproteins and increased in LDL and HDL during the first week of life. After birth, VLDL became enriched in apolipoproteins C and E, whereas HDL was enriched in apolipoprotein C and depressed in apolipoprotein E. The developmental changes in plasma lipoprotein levels and compositions in rats during the first week of life are comparable to those described in humans.
