Clinical Pharmacodynamic Effects of the Growth Hormone Receptor Antagonist Pegvisomant:... - 0 views

  •  
    Pegvisomant shown to provide more GH, IGF-1 suppression compared to octreotide. The doses used were 40, 60, and 80 mg SQ. The higher dose resulted in the greatest suppression.

Does growth hormone cause cancer? [Clin Endocrinol (Oxf). 2006] - PubMed - NCBI - 0 views

  •  
    epidemiological studies are the only thing that has linked GH to cancer risk; review of human studies of children and adults finds no increase risk of cancer associated with HGH therapy.

Growth hormone treatment and risk of recurr... [Childs Nerv Syst. 2009] - PubMed - NCBI - 0 views

  •  
    Growth hormone did not show to increase brain tumor progression or recurrence; this dispels the myth that GH causes/progresses cancer.

A potential role of endogenous progesterone in mod... [Clin Endocrinol (Oxf). 2009] - P... - 0 views

  • These data also suggest that endogenous progesterone could play a modulation role on pituitary hormone secretion, stimulating GH and PRL release and enhancing the inhibitory action of sleep on TSH secretion.
  • normally cycling young women, daytime GH and PRL secretions are increased in luteal phase
  •  
    normal luteal progesterone production stimulate HGH release

Thieme E-Journals - International Journal of Sports Medicine / Abstract - 0 views

  •  
    Only abstract available here: compound resistance treaining in highly trained young men found to increase GH and Testosterone over isolation exercises. Those that trained > 2 years had significnt increase in Testosterone pre/post exercise compared to no statistical change in those traing < 2 years.

Testosterone and Estradiol Regulate Free Insulin-Like Growth Factor I (IGF-I), IGF Bind... - 0 views

  •  
    testosterone and Estradiol effect IGF-1 levels.  This small study looked at 8 men and 8 postmenopausal women.  Findings:  low testosterone and high estradiol decrease IGF-1 availability.   Estradiol in postmenopausal women will result in a decrease in IGF-1 through an elevation of IGFBP-1.  In men, testosterone replacement stimulates increased HGH secretion and resultant IGF-1 secretion

Ghrelin-Induced Food Intake Is Mediated via the Orexin Pathway - 0 views

  • Ghrelin, a peptide produced in the stomach and hypothalamus, stimulates feeding and GH secretion
  • Centrally administered ghrelin exerts an orexigenic activity through the neuropeptide Y (NPY)
  • though ghrelin is predominantly produced in endocrine cells of the stomach (17, 18), it is also synthesized in the hypothalamic arcuate nucleus (1, 19), a critical region for feeding
  •  
    ghrelin stimulates feeding through orexin signaling.

Administration route-dependent effects of estrogens on IGF-I levels during fixed GH rep... - 0 views

  •  
    oral estrogen therapy decreased IGF-1 concentrations in those women taking growth hormone, requiring high dosing of HGH versus that in women using estrogen through a transdermal approach.
