Sebastian Kalamajski et al.
Matrix biology : journal of the International Society for Matrix Biology, 29(4), 248-253 (2010-01-19)
Small leucine-rich proteoglycans/proteins (SLRPs) are associated with collagen fibril formation, and therefore important for the proper formation of extracellular matrices. SLRPs are differentially expressed in tissues and during pathological conditions, contributing to the development of connective tissue properties. The binding

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)

Journal of the National Cancer Institute, 105(19), 1463-1473 (2013-09-21)
L-type amino acid transporters (LATs) uptake neutral amino acids including L-leucine into cells, stimulating mammalian target of rapamycin complex 1 signaling and protein synthesis. LAT1 and LAT3 are overexpressed at different stages of prostate cancer, and they are responsible for

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

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
