Identification, by RT-PCR, of eight novel I₂-conotoxins from the worm-hunting cone snails Conus brunneus, Conus nux, and Conus princeps from the eastern Pacific (Mexico)
Autor: R, Zamora-Bustillos, R, Rivera-Reyes, M B, Aguilar, E, Michel-Morfín, V, Landa-Jaime, A, Falcón, E P, Heimer
Publikováno v: Peptides. 53
Marine snails of the genus Conus (∼500 species) are tropical predators that produce venoms for capturing prey, defense and competitive interactions. These venoms contain 50-200 different peptides ("conotoxins") that generally comprise 7-40 amino ac

Feedlot performance, carcass characteristics, hormones, and metabolites in steers actively immunized against growth hormone-releasing factor
Autor: Jeffrey D. Armstrong, E. P. Heimer, R. W. Harvey, Robert M. Campbell
Publikováno v: Journal of Animal Science. 71:2853-2859
Large-framed Simmental and Charolais steers were actively immunized against growth hormone-releasing factor (GRF) to evaluate the effect on growth, carcass characteristics (especially intramuscular fat deposition), and concentrations of somatotropin

Effect of feed restriction on serum somatotropin, insulin-like growth factor-I-(IGF-I) and IGF binding proteins in cyclic heifers actively immunized against growth hormone releasing factor
Autor: R. W. Harvey, Jeffrey D. Armstrong, W. S. Cohick, Robert M. Campbell, E. P. Heimer
Publikováno v: Domestic Animal Endocrinology. 10:315-324
Feed restriction often increases serum somatotropin (ST) and decreases insulin-like growth factor-I (IGF-I) in ruminants; however, the mechanisms responsible for this change in ST and IGF-I are not well defined. We investigated the effects of feed re

In Vitro Stability of Growth Hormone Releasing Factor (GRF) Analogs in Porcine Plasma
Autor: Thomas F. Mowles, L. R. Jensen, Y.-C. Pan, A. M. Felix, E. P. Heimer, C.-M. Su
Publikováno v: Hormone and Metabolic Research. 23:15-21
The stability of growth-hormone releasing factor (growth regulating factor; GRF) analogs in porcine plasma was examined. GRF analogs were incubated in porcine plasma at 37 degrees C, extracted and subsequently analyzed using high performance liquid c

Peptide synthesis catalyzed by the Glu/Asp-specific endopeptidase. Influence of the ester leaving group of the acyl donor on yield and catalytic efficiency
Autor: J, Bongers, W, Liu, T, Lambros, K, Breddam, R M, Campbell, A M, Felix, E P, Heimer
Publikováno v: International journal of peptide and protein research. 44(2)
We recently described a two-step enzymatic semisynthesis of the superpotent analog of human growth hormone releasing factor, [desNH2Tyr1,D-Ala2,Ala15]-GRF(1-29)-NH2 (4), from the precursor, [Ala15,29]-GRF(4-29)-OH (1). C-Terminal amidation of 1 to fo

Publikováno v: Journal of animal science. 72(6)
Cyclic females actively immunized against growth hormone-releasing factor (GRF; n = 5) or human serum albumin (HSAi; n = 4) were used to determine the effects of reduced serum somatotropin (ST) and IGF-I on metabolism and production in gestating and

Endocrine events prior to puberty in heifers: role of somatotropin, insulin-like growth factor-I and insulin-like growth factor binding proteins
Autor: J D, Armstrong, R L, Stanko, W S, Cohick, R B, Simpson, R W, Harvey, B G, Huff, D R, Clemmons, M D, Whitacre, R M, Campbell, E P, Heimer
Publikováno v: Journal of physiology and pharmacology : an official journal of the Polish Physiological Society. 43(4 Suppl 1)
We have utilized active immunization against growth hormone releasing factor (GRF) to investigate relationships among somatotropin (ST), insulin-like growth factor-I (IGF-I), IGF binding proteins (IGFBP) and ovarian function in heifers. Active immuni
