Growth hormone is a peptide hormone released by the anterior pituitary in response to stress. It raises circulating glucose levels by increasing rates of gluconeogenesis, glycogenolysis, and proteolysis. Patients with excessive growth hormone production (e.g., pituitary tumors) exhibit insulin resistance...
hormone - the secretion of an endocrine gland that is transmitted by the blood to the tissue on which it has a specific effect endocrine, internal secretion secretion - a functionally specialized substance (especially one that is not a waste) released from a gland or cell ACTH, adrenocorticotro...
Growth hormone (GH) release is regulated by neurohormones released from secretory neurones terminating in the median eminence (ME) of the hypothalamus, which are transported by the hypophysial portal system to the adenohypophysis (Fig. 1). Other pathways of the central nervous system (CNS) act...
The meaning of GROWTH HORMONE-RELEASING HORMONE is a neuropeptide released by the hypothalamus that stimulates the release of growth hormone —abbreviation GHRH—called also growth hormone-releasing factor.
Growth hormone release is not continuous; it is released in a number of ‘bursts’ or pulses every three to five hours[13]. The pulsatile release of GH into circulation is regulated by the concerted actions of the hypothalamic hormones GH-releasing hormone (GHRH), which stimulates the pituitary...
The release of prolactin (PRL) and growth hormone (GH) of pituitary grafts and in situ glands was investigated using perifusion techniques. Whole pituitary or anterior lobe grafts were used. The grafts or the in situ glands were incubated alone in a chamber. The hypophysis of dioestrous-1 gl...
Pulsatile growth hormone (GH) release is under the control of two cyclically released hypothalamic peptides—growth hormone releasing hormone (GHRH) and somatostatin. Areas of the hypothalamus responsible for the control of GH release are the somatostatin neuron-containing periventricular nucleus (PeV) ...
Control of growth hormone release Growth hormone release is not continuous; it is released in a number of ‘bursts’ or pulses every three to five hours[13]. The pulsatile release of GH into circulation is regulated by the concerted actions of the hypothalamic hormones GH-releasing hormone (GHR...
Growth hormone (GH), also known as somatotropin, is a member of a family of growth factors that includes prolactin, placental lactogens, proliferins and somatolactin (1, 2). It is synthesized primarily by somatotropes in the anterior pituitary and is released as an endocrine hormone. Other ...
We administered growth-hormone releasing hormone (GHRH), clonidine or thyrotropin-releasing hormone (TRH) as intravenous boli each in three different randomized mornings to nine well-controlled Type 1 diabetic men and to six age-matched healthy men who served as controls. GHRH and clonidine evoked ...
