M Sakamoto et al.
The Journal of clinical endocrinology and metabolism, 56(1), 202-204 (1983-01-01)
Recent studies on the nucleotide sequence of cloned DNA complementary to mRNA for preproenkephalin from bovine adrenal medulla and human pheochromocytoma have revealed that this precursor molecule contains four copies of methionine-enkephalin (Met-Enk) and one copy each of leucine-enkephalin (Leu-Enk)
T Yoshimasa et al.
The Journal of clinical investigation, 69(3), 643-650 (1982-03-01)
To elucidate the physiological and pathophysiological significance of methionine- and leucine-enkephalin (Met-and Leu-enkephalin, respectively) in human sympathoadrenal system, the contents of these peptides in normal human sympathetic nervous system, adrenal medulla, and pheochromocytomas were determined by specific radioimmunoassays combined with
Marika Leenders et al.
Nutrition reviews, 69(11), 675-689 (2011-10-28)
Amino acids function as precursors for de novo protein synthesis. In addition, however, they play a key role as nutritional signals that regulate multiple cellular processes. There is ample in vitro and in vivo evidence showing that muscle tissue responds
Luc J C van Loon
Current opinion in clinical nutrition and metabolic care, 15(1), 71-77 (2011-11-01)
Amino acids do not merely represent precursors for de-novo protein synthesis, but also function as nutritional signals regulating various metabolic processes. In fact, ample evidence has been generated to show that various tissues respond to changes in amino acid availability
William I A Haynes et al.
The Journal of neuroscience : the official journal of the Society for Neuroscience, 33(11), 4804-4814 (2013-03-15)
The identification of a hyperdirect cortico-subthalamic nucleus connection highlighted the important role of the subthalamic nucleus (STN) in regulating behavior. However, this pathway was shown primarily from motor areas. Hyperdirect pathways associated with cognitive and motivational cortical regions are particularly
