Nutritional regulators of the hypothalamic–pituitary axis in pigs
Autor: R. R. Kraeling, G. B. Rampacek, C. R. Barb
Publikováno v: Bioscientifica Proceedings.
Nutritional signals are detected by the central nervous system (CNS) and translated by the neuroendocrine system into signals that alter secretion of LH and growth hormone (GH). Furthermore, these signals directly affect the activity of the pituitary

Gene expression in the brain-pituitary adipose tissue axis and luteinising hormone secretion during pubertal development in the gilt
Autor: R. Rekaya, G. J. Hausman, C. R. Barb
Publikováno v: Bioscientifica Proceedings.
The occurrence of puberty in the female is due to the interplay of central and peripheral mechanisms in which the hypothalamic-pituitary-ovarian axis regulates growth and gonadal function, as well as adipocyte hormone secretion. Hypothalamic GnRH mRN

Insulin-like growth factor-I feedback regulation of growth hormone and luteinizing hormone secretion in the pig: evidence for a pituitary site of action
Autor: C. R. Barb, Gary J. Hausman
Publikováno v: Animal, Vol 3, Iss 6, Pp 844-849 (2009)
Three experiments (EXP) were conducted to determine the role of insulin-like growth factor-I (IGF-I) in the control of growth hormone (GH) and LH secretion. In EXP I, prepuberal gilts, 65 ± 6 kg body weight and 140 days of age received intracerebrov

Patterns of gene expression in pig adipose tissue: Insulin-like growth factor system proteins, neuropeptide Y (NPY), NPY receptors, neurotrophic factors and other secreted factors
Autor: Gary J. Hausman, C R Barb, R. G. Dean
Publikováno v: Domestic Animal Endocrinology. 35:24-34
Although cDNA microarray studies have examined gene expression in human and rodent adipose tissue, only one microarray study of adipose tissue from growing pigs has been reported. Total RNA was collected at slaughter from outer subcutaneous adipose t

Failure of short-term feed restriction to affect luteinizing hormone and leptin secretion or subcutaneous adipose tissue expression of leptin in the prepuberal gilt
Autor: C. R. Barb, G. J. Hausman, H. A. Hart, D. E. Reeves, M. J. Azain
Publikováno v: Canadian Journal of Animal Science. 87:191-197
Previously we reported that 24-h fast increased serum non-esterified fatty acids (NEFA) concentrations, and decreased leptin pulse frequency, but not mean serum leptin concentrations in the OVX prepuberal gilt. The present study was conducted to dete

Effects of N-methyl-D,L-aspartate on LH, GH, and testosterone secretion in goat bucks maintained under long or short photoperiods1
Autor: Brou Kouakou, S Gazal, J B Barrett, S. Gelaye, E.A. Amoah, C R Barb
Publikováno v: Journal of Animal Science. 80:1623-1628
Photoperiod modulates reproduction in goats. We tested the hypothesis that the excitatory glutamatergic tone is reduced in the photoinhibited goat. The objectives of this study were to determine the effect of photoperiod and glutamatergic stimulation

Evidence for a Luteinizing Hormone Surge Center in the Hypothalamus of the Pig1
Autor: C R Barb, R R Kraeling, B Johnson, George B. Rampacek
Publikováno v: Biology of Reproduction. 58:1199-1205
Studies were conducted to determine whether there is an LH surge generator in the hypothalamus of the pig. In experiment 1, 157-day-old ovariectomized (OVX) gilts received 1.5 microg estradiol benzoate (EB)/kg BW i.m. every 12 h from 0 through 24, 48

Glucose and free fatty acid modulation of growth hormone and luteinizing hormone secretion by cultured porcine pituitary cells1
Autor: C R Barb, G. B. Rampacek, R R Kraeling
Publikováno v: Journal of Animal Science. 73:1416-1423
The influence of glucose and free fatty acids (FFA) on LH and GH secretion from porcine pituitary cells was examined in culture. Cells were challenged with 10 -9 , 10 -8 , or 10 -7 M GnRH; 10 -9 , 10 -8 , or 10 -7 M [Ala 15 ]-h growth hormone-releasi
