In nonlaying hens or in cockerels, the administration of estrogen dramatically increases the level of plasma triglycerides (1, 2). Luskey et al. (3) have shown that one effect of estrogen was to increase the rate of synthesis of the very low density lipoproteins (VLDIJ’ proteins. The mechanism for this induction is presumably through an increase in mRNA for the yolk proteins (4-6). In a recent ...

The inductions of hepatic fatty acid synthesis, estrogen-specific plasma proteins, plasma lipids, and apolipoproteins by a single subcutaneous injection of diethylstilbestrol (40 mg/kg body weight) have been examined in immature male turkeys. Estrogen induced the appearance of phosvitin, lipovitellin, and apoVLDL-II in the blood plasma. The highest concentrations of these estrogen-specific plas...

The plasma lipoproteins of the Zucker fatty rat were characterized with respect to lipid and apoprotein composition, and results were compared with those obtained from lean controls. Information on apoproteins was obtained from gel filtration experiments and electrophoresis on polyacrylamide gels. Very low density lipoproteins (VLDL) were increased several-fold in fatties, and 78% of their mass...
