13C NMR study of hepatic pyruvate carboxylase activity in tumor rats

Autor: Lloyd M. Nyhus, Katherine J.M. Liu, Robert A. Kleps, Thomas O. Henderson

Publikováno v: Biochemical and Biophysical Research Communications. 179:366-371

Alanine and lactate, as major gluconeogenic substrates, must be converted into oxaloacetate by way of pyruvate carboxylase before their entry into gluconeogenesis. Although it is well known that hepatic gluconeogenesis from these substrates is increa

A sex-specific metabolite identified in a marine invertebrate utilizing phosphorus-31 nuclear magnetic resonance

Autor: Romuald N. Lipcius, Thomas O. Henderson, Robert A. Kleps, Terrell C. Myers

Publikováno v: PLoS ONE
PLoS ONE, Vol 2, Iss 8, p e780 (2007)

Hormone level differences are generally accepted as the primary cause for sexual dimorphism in animal and human development. Levels of low molecular weight metabolites also differ between men and women in circulating amino acids, lipids and carbohydr

Gluconeogenesis in the liver of tumor rats

Autor: Thomas O. Henderson, Maria C. Reyes, Robert A. Kleps, Lloyd M. Nyhus, Katherine J.M. Liu

Publikováno v: The Journal of surgical research. 49(2)

Altered gluconeogenesis is frequently observed in cancerous hosts. To define its derangements in the liver, we studied glucose and glycogen production in the perfused livers of tumor-bearing rats using 13 C NMR spectroscopy. Nine Fischer 344 rats wer
