No footnotes date February 2011 The gastrointestinal hormones or gut hormones constitute a group of hormone s secreted by enteroendocrine cell s in the stomach , pancreas , and small intestine that control various functions of the digestive organs. Later studies showed that most of the gut peptides, such as secretin , cholecystokinin or substance P , were found to play a role of neurotransmitter s and neuromodulator s in the central and peripheral nervous systems. Enteroendocrine cells do not form endocrine glands but are spread throughout the digestive tract. They exert their autocrine and paracrine actions that integrate all of gastrointestinal function. Types of Gastrointestinal hormones The gastrointestinal hormones can be divided into three main groups based upon their chemical structure . Gastrin family Gastrin cholecystokinin family gastrin and cholecystokinin Secretin family secretin , glucagon , vasoactive intestinal peptide and gastric inhibitory peptide Somatostatin family Motilin family Substance P . Ghrelin is a peptide hormone released from the stomach and is often referred to as the hunger hormone since high levels of it are found in individuals that are fasting. Ghrelin antagonistic treatments can be used to treat illnesses such as anorexia and loss of appetites in cancer patients. Ghrelin treatments for obesity are still under intense scrutiny and no conclusive evidence has been reached. This hormone stimulates growth hormone release. Cholecystokinin is responsible for gall bladder secretions, gastrointestinal motility as well as pancreatic exocrine secretions. Peptide YY is involved mostly in satiation modulation. Pancreatic polypeptide function is most apparent in control of gastrointestinal motility and satiation Amylin controls glucose homeostasis and gastric motility Glucose dependent insulinotropic polypeptide possesses an acute influence on food ...

Adipokinetic hormone AKH is a short peptide hormone that has been studied in insect s. It is a lipid mobilising hormone and is responsible for regulating fuel transport in the haemolymph , for redirecting energy to other processes as required by the insect.

A counterregulatory hormone is a hormone that opposes the action of another. The action of insulin is counterregulated by glucagon , adrenaline epinephrine , noradrenaline norepinephrine , cortisol , and growth hormone . These counterregulatory hormones the term is usually used in the plural raise the level of glucose in the blood by promoting glycogenolysis , gluconeogenesis , ketosis , and other catabolic processes. In healthy people, counterregulatory hormones constitute a principal defense against hypoglycemia , and levels are expected to rise as the glucose falls. Persistent elevation of a counterregulatory hormone can reduce a person s insulin sensitivity sensitivity to insulin . Similarly, the natriuretic peptide s counterregulate against renin , angiotensin , and aldosterone which elevate blood pressure. ref cite journal title Natriuretic peptides Physiology, therapeutic potential, and risk stratification in ischemic heart disease author Stein BC, Levin RI journal Am Heart J volume 135 issue 5 pages 914 23 date May 1998 pmid 9588425 Verify source date June 2011 ref In the reproductive system, inhibins and follistatin counterregulate activins , to control follicle stimulating hormone and so the release of gonads . ref cite journal journal Semin Reprod Med. date 2004 Aug volume 22 issue 3 pages 209 17 title Inhibins, activins, and follistatin in the aging female and male author Hurwitz JM, Santoro N pmid 15319823 Verify source date June 2011 ref Inhibins and activins also regulate bone mass. ref cite journal journal Mol Cell Endocrinol. date 2009 10 30 volume 310 issue 1 2 pages 11 20 title Regulation of osteoblastogenesis and osteoclastogenesis by the other reproductive hormones, Activin and Inhibin author Nicks KM, Perrien DS, Akel NS, Suva LJ, Gaddy D pmid 19615428 pmc 2951729 ref References reflist Further reading cite journal title Sweet talk in the brain glucosensing ... 305 pmid 20375118 pmc 2886811 DEFAULTSORT Counterregulatory Hormone Category Hormones of glucose metabolism ... more details

Multiple issues unreferenced December 2009 unreferenced August 2010 expert August 2010 Stress hormones such as cortisol and norepinephrine are released by the body in situations that are interpreted as being potentially dangerous. The hormone regulating system is known as the endocrine system . Cortisol is believed to affect the metabolism metabolic system and norepinephrine is believed By whom date June 2011 to play a role in ADHD as well as Depression mood depression and hypertension . Stress hormones act by mobilizing energy from storage to muscles, increasing heart rate, blood pressure and breathing rate and shutting down metabolic processes such as digestion, reproduction, growth and immunity. Constant stress causes continual release of various stress hormones which can cause A depletion of energy storage High blood pressure Stress induced hypertension Effects on metabolic processes Ulcers digestion Hampered growth Decrease in testosterone levels in males and irregular menstrual cycles in females. Increased likelihood of infectious diseases. Stress hormones rise in the body during any neuroendocrine reaction such as surgery and they remain high as long as 72 hours, after which all these hormones return to their normal level, the last being cortisol. Currently there are medications available which block the release of stress hormones.

Prolactin releasing hormone , also known as PRLH, is a hypothetical human hormone or hormone releasing factor. Existence of this factor has been hypothesized as prolactin is the only currently known hormone for which almost exclusively negative regulating factors are known such as dopamine , Leukemia inhibitory factor LIF , some prostaglandins but few stimulating factors. While many PRL stimulating and enhancing factors are well known such as TRH , oxytocin , steroid hormones those have primary functions other than stimulating prolactin release and the search for hypothetical releasing factor or factors continues. The PRLH prolacting releasing peptide identified in 1998 was a candidate for this function, however as of 2008 it appears its function is not yet completely elucidated. ref name Lin 2008 cite pmid 18204826 ref Reflist Category Human hormones Molecular cell biology stub ... more details
A gonadotropin releasing hormone analogue GnRH analogue or analog , also known as a luteinizing hormone releasing hormone agonist LHRH agonist or LHRH analogue is a synthetic peptide medication drug modeled after the human hypothalamus hypothalamic gonadotropin releasing hormone GnRH . A GnRH analogue is designed to interact with the GnRH Receptor biochemistry receptor and modify the release of pituitary gonadotropin s Follicle stimulating hormone FSH and LH for therapeutic purposes. Shortly after the discovery of GnRH by Nobel laureates Roger Guillemin Guillemin and Andrew V. Schally Schally researchers tried to modify the GnRH decapeptide with the intent to synthesize stimulating and blocking variants. Two types of analogues have to be distinguished Agonists main Gonadotropin releasing hormone agonist A gonadotropin releasing hormone agonist GnRH agonist is an analogue that activates the GnRH receptor resulting in increased secretion of FSH and LH. Initially it was thought that agonists could be used as potent and prolonged stimulators of pituitary gonadotropin release, but it was soon recognized that agonists, after their initial stimulating action termed a flare effect eventually caused a paradoxical and sustained drop in gonadotropin secretion. This second effect was termed downregulation and can be observed after about 10 days. While this phase is reversible upon stopping the medication, it can be maintained when GnRH agonists use is continued for a long time. Antagonists main Gonadotropin releasing hormone antagonist A gonadotropin releasing hormone antagonist GnRH antagonist is an analogue that blocks the GnRH receptor resulting in an immediate drop in gonadotropin FSH, LH secretion. The GnRH antagonist is primarily used in IVF treatments to block natural ovulation. All GnRH analogues are contraindicated in pregnancy pregnancy category X . References Speroff L, Glass RH, Kase NG.

Non tropic hormones are hormones that directly stimulate target cells to induce effects. This differs from the Tropic hormone tropic hormones , which act on another endocrine gland . Most endocrine glands, such as the gonad s, pancreas , and adrenal gland s, produce non tropic hormones. Those released from the pituitary gland in the brain include Oxytocin posterior lobe stimulates milk letdown in females. Prolactin PRL anterior lobe is remarkable for the diversity of its effects among vertebrate species. The varied roles suggest that prolactin is an ancient hormone with functions that have diversified during the evolution of vertebrate groups. Melanocyte stimulating hormone MSH intermediate lobe regulates the activity of pigment containing cells in the skins of some amphibians. In mammals, MSH act on neurons in the brain, inhibiting hunger. Growth hormone GH primary stress hormone ref cite book last Cambell first Neil A. authorlink coauthors Jane B.
