David Nutting, PhD
My long-term goal is to contribute to our understanding of endocrine and nutrient
regulation of metabolism, particularly with respect to uptake of nutrients by the
GI tract and their subsequent metabolism, including induction of other physiologic
or pathologic effects. I am presently trying to identify the putative "chylomicron
remnant receptor" in the proximal intestine, then study its regulation and role in
triglyceride, cholesterol, and phospholipid metabolism by the small intestine. I have
also been collaborating on studies of the long-acting somatostatin analog, octreotide,
on calcium and nitrogen metabolism in humans. Unexpectedly, we found that octreotide
enhanced calcium retention, first in boys with Duchenne muscular dystrophy, then in
normal and cirrhotic adults. And in a patient with Paget's disease, acute treatment
with octreotide simultaneously enhanced bone formation and inhibited bone breakdown.
Finally, I have also done collaborative studies in cattle, examining the interaction
between genotype (Brahman vs. Angus) and the environment (two different forages, bermuda
vs. fescue). We found marked effects of genotype on serum cholesterol and that the
effect of forage on cholesterol levels depends on the genotype of the calf. We also
found that serum cholesterol in heifer calves at weaning predicts future milk production
during first lactation 2 1/2 years later. This finding appears to have potential practical
use for selecting which young heifers to keep to be future brood-cows, since the amount
of milk a beef cow can produce heavily influences the growth rate of her calves. Techniques
we employ include standard lipid and lipoprotein separation and analyses, mesenteric
lymph duct cannulation (to collect and analyze intestinal lymph), Western ligand blotting,
and rocket immunoassay for apolipoproteins.
