“…The only effect that persisted through 13 days of injections was reduced hepatic lipoprotein lipase expression (LPL), a capillary enzyme that hydrolyzes TAGs of circulating lipoproteins (Li et al, 2010). Increased expression of LPL is also seen in the white adipose tissue of fasted mammals (Botion, 2001). Further, there is indirect evidence that leptin contributes to NEFA release into circulation.…”

All organisms face tradeoffs with regard to how limited energy resources should be invested. When is it most favorable to grow, to reproduce, how much lipid should be allocated to storage in preparation for a period of limited resources (e.g., winter), instead of being used for growth or maturation? These are a few of the high consequence fitness “decisions” that represent the balance between energy acquisition and allocation. Indeed, for animals to make favorable decisions about when to grow, eat, or reproduce, they must integrate signals among the systems responsible for energy acquisition, storage, and demand. We make the argument that leptin signaling is a likely candidate for an integrating system. Great progress has been made understanding the leptin system in mammals, however our understanding in fishes has been hampered by difficulty in cloning fish orthologs of mammalian proteins and (we assert), underutilization of the comparative approach.

“…Studies showed that during fasting, LPL activity is down regulated in adipocytes but it does not change in myocytes. In addition, during the refeeding period, LPL activity increases in adipocytes in order to store energy (Botion, 2001;Albalat et al, 2007). The relationship of LPL with insulin resistance has not always been consistent (Corcoran et al, 2007).…”

This study was conducted to determine if glycated albumin is associated with marbling in beef cattle. Crossbred steers (n=113) were assigned randomly to different treatments to determine the effects of feeding strategies (with anabolic growth implants, CONV; without growth implants, NAT) on blood proteins, glucose, and insulin. Total serum protein and albumin were not different between marbling scores and feeding strategies. Glycated albumin was not correlated with marbling scores. Plasma glucose concentration was greater in steers with a marbling score of slight compared to all other marbling scores, and NAT feeding strategy had greater concentration than CONV (P = 0.02). Plasma insulin in steers with marbling scores of modest and moderate were greater than small (P = 0.01). However, they were all similar to marbling scores of slight and slightly abundant. More research is necessary to determine whether glycated albumin is associated with marbling in beef cattle. I would like to thank all of the faculty and staff in the NDSU Animal Sciences Department, and the staff of Dr. Vetter's lab. I also would like to thank all the animal sciences graduate students for their help and support. Lastly, I would like to thank my family for their support because without this support, I would never have finished my master degree. Thank you very much. v

The lipemic response to a high-fat meal is greater in men than in women. However, sex-related differences in the metabolic fate of ingested fat are not well understood. The purpose of this study was to measure the recovery of ingested fat in plasma fractions of chylomicrons (CHYLO), VLDL, and plasma fatty acids, as well as in expired breath (i.e., oxidation) in men and women. Nonobese subjects (n = 10; 5 men, 5 women) consumed 0.7 g fat/kg body weight containing 7 mg/kg of [1,1,1-13C]-trioleate the morning after an overnight fast. Plasma total triglyceride (TG) concentration and 13C recovery in the CHYLO, VLDL, and plasma fatty acid fractions, as well as expired breath samples, were measured over the 11-h period after the meal. Plasma total TG excursion was greater (P < 0.05) in men than in women during the 11-h period after the meal. Similarly, the recovery of the ingested tracer-labeled fat in the CHYLO fraction was greater in men than in women (main effect for sex; P < 0.05). Recovery of ingested tracer-labeled fat in VLDL, the plasma fatty acid fraction, and expired breath did not differ in men and women. Therefore, the elevated postprandial lipemia found in men compared with women was due to a prolonged availability of the lipid in chylomicrons, but was not related to differences in oxidation rates or incorporation of the ingested lipid into VLDL by the liver.
