Plasma levels of apolipoprotein M in normal and complicated pregnancy.

Apolipoprotein M (apoM) is mainly associated with high-density lipoprotein in human plasma. Despite several studies suggesting apoM as an anti-atherogenic, its function is not yet fully understood. Plasma apoM was measured in normal pregnancies at four different gestational ages and in the postpartum period to investigate whether the concentration of apoM changes during pregnancy.
