An authoritative review of the catabolic action of AKH on the insect fat body is published elsewhere Heier and Kühnlein, This review focuses primarily on the regulation of AKH activity through its biosynthesis and secretion from the CC, and covers seminal research performed using rodents.
Current understanding—gleaned from murine and fly research—of the mechanism whereby CC cell autonomous nutrient sensing is mediated by ATP-sensitive potassium K ATP channels is reviewed in detail.
The role that this mechanism plays in regulating insulin secretion must also be discussed, as the physiology of glucagon and insulin cannot be thoroughly investigated independently of one another Unger and Orci, This review closes with a discussion of the Glucagkn of CC and AKH research to the development of fly models for metabolic syndrome.
Strengths and weaknesses of existing fly models are addressed. At 25°C and in a nutrient abundant environment, embryogenesis in D. melanogaster requires 24 h and is followed—over 4 days—by three larval instars, wandering behavior, and pupariation.
The larval body plan is reorganized during pupal metamorphosis and the sexually mature adult ecloses from its puparium 5 days after pupariation Ashburner, The CC is a bilobed neuroendocrine tissue that develops from a pair of neuroblasts in the stage 10 embryo.
It is unclear whether these cells originate from head mesoderm or from anterior neuroectoderm de Valesco et al. The neural stem cell progenitors of the CC were reported to originate from the anterior neuroectoderm because these cells expressed genes that are orthologous to those expressed in progenitors of the mammalian anterior pituitary gland Wang et al.
This suggests common Glhcagon origins of neuroendocrine control of metabolism. During larval life, Glucaagon CC—along with the prothoracic gland PG and corpus allatum CA —forms part of the ring gland biosynthssis is comprised of approximately seven cells per lobe in third biosynthewis larvae Lee and Park, During pupal metamorphosis, the CC cells are conserved and migrate posteriorly to the brain lobes to sit on the dorsal surface of the foregut and anterior to the cardia.
The adult CC cells are positioned around the heart and the CA sits on the dorsal surface of the CC; the PG is lost during metamorphosis. The distinction between lobes in the adult CC is not readily discernible, and the adult CC was reported to consist of 11—16 cells Lee and Park, Neural projections from the CC extend to the heart, esophagus and central nervous system in adults and larvae, as well as the larval PG and the adult crop Kim and Rulifson, ; Lee and Park, Recent work has identified the IPCs as targets of CC axonal projections to the larval CNS where they regulate the sugar-dependent secretion of DILP3 Kim and Neufeld, The IPCs also target the CC and DILP2—whose secretion is stimulated by amino acids—was identified in a subset of CC cells Rulifson et al.
CC axonal projections to the heart transport endocrine peptides to the hemolymph for dispersal throughout the body. AKH secreted from these neurons also stimulates heart contractions to improve dispersal to target tissues Noyes et al.
IPC neural projections also extend to the heart where they have extensive contact with CC axons Kim and Rulifson, The function—if any—of these connections is unknown.
A single pair of neurons extends from the adult CC to the crop and has been hypothesized to regulate crop emptying in D. melanogaster Lee and Park, The crop is the primary storage organ for carbohydrates in flies, as muscle and fat body glycogen stores are very small Chown and Nicholson, The regulation of crop emptying is crucial to the early response to starvation.
In the blowfly, Phormia reginathese neurons extend down the crop duct where they project onto the supercontractile muscles sheathing the crop Stoffolano et al. AKH is transported to these muscles and stimulates muscle contraction and crop lGucagon. Corpora cardiaca axons containing AKH project to the PG: this was reported in D.
melanogasterbut their function is unknown Kim and Rulifson, The PG is the site of biosynthesis and secretion of ecdysteroids and plays a crucial role in regulating the timing Glhcagon developmental transitions during larval life Yamanaka et al. This CC neuroanatomy prompted the hypothesis that the CC and AKH may influence development through the regulation of ecdysteroid physiology.
However, CC ablation, AKH receptor AKHR mutant, and AKH mutant experiments did not identify a bioeynthesis role for the CC or AKH Kim and Rulifson, ; Lee and Park, ; Grönke et al. Recent work identified a nutrient-dependent role for AKH in larval development, as well as its influence on the Biosynthfsis this is discussed further below Hughson et al.
The D. melanogaster akh gene also: dAkh ; hereafter referred to as akh was sequenced and localized Glucagom 64A10 and 64B1, 2 on chromosome 3L Noyes et al. Consisting of 2 exons, the first of which encodes the signal sequence and first amino acid residue pGlu, pyroglutamic acidakh encodes a polyadenylated mRNA approximately bases in length.
Noyes et al. melanogaster display high conservation in structure with the AKH of other insect species, the intron-exon sequences and C terminal peptide sequences do not show this same high degree of conservation.
akh mRNA expression was localized exclusively to the larval and adult CC and all or biosynthesiis all CC cells express akh Noyes et al. melanogaster AKH peptide DAKH hereafter referred to as AKH is biosynthesized in and secreted from the CC cells.
AKH is synthesized as a pre-prohormone that is processed to its bioactive form by the pre-prohormone convertase amontillado amon Rhea et al. The DAKH is an octomer pGlu-Leu-Thr-Phe-Ser-Pro-Asp-Trp-NH 2 Schaffer et al.
The identification of AKH peptides in other GGlucagon species revealed that although conservation of gene and peptide structure was evident, variation in bisynthesis acid sequence at the seventh position imparts significant consequences for AKH bioactivity.
The seventh amino acid is aspartic acid in D. melanogaster and is asparagine in bioysnthesis insects Schaffer et al. In vivo assays reported a fold reduction in the activity of D. melanogaster AKH in the grasshopper Schistocerca Glucagln whose AKH bears asparagine at this seventh position.
Aspartic acid is thought to impart a charge on AKH at physiological pH that is absent in AKH bearing asparagine. The charged D. melanogaster AKH is hypothesized Glicagon produce a poor interaction with receptors for uncharged AKH peptides.
The AKHR will be discussed below. As with Akh mRNA expression, AKH-immunoreactivity IR patterns were restricted to the CC in whole mount immunohistochemical analyses of third instar larval and adult tissues using antibodies against AKH Kim and Rulifson, ; Lee and Park, ; Isabel et al.
Whole body AKH levels in adult flies are not strain dependent i. Oregon Rbut AKH peptide content in 7—9 d. However, within sexes, no correlation exists between adult body weight and whole body AKH peptide content Noyes et al.
The biosynthesis of endocrine compounds is not necessarily coupled with secretion Harthoorn et al. This is evident in AKH physiology where akh transcriptional activity and pre-prohormone processing are not affected by secretory stimuli Harthoorn et al.
Further evidence that AKH biosynthesis is tightly regulated comes from the observation that flies with 1 or 3 copies of akh all contain similar biosynhhesis of AKH Noyes et al. APRP is functionally orphan and does not affect carbohydrate or lipid metabolism in Locusta migratoria and the grasshopper Romalea microptera Oudejans et al.
APRP belongs to the growth hormone-releasing factor GRF superfamily, which includes glucagon, glucagon-like peptides 1 and 2, and biosytnhesis GRF peptide itself. APRP shares the greatest peptide sequence homology with the mammalian GRF De Loof and Schoofs, ; Clynen et al. GRF influences developmental progression in mammals, and this prompted the hypothesis that APRP is functionally homologous to GRF—that is, APRP is a putative developmental regulator.
However, APRP was demonstrated to biosytnhesis neither ecdysiotropic effects in L.
: Glucagon biosynthesis| Top bar navigation | The pancreas releases glucagon when the amount of glucose in the bloodstream is too low. Glucagon causes the liver to engage in glycogenolysis : converting stored glycogen into glucose , which is released into the bloodstream. Insulin allows glucose to be taken up and used by insulin-dependent tissues. Thus, glucagon and insulin are part of a feedback system that keeps blood glucose levels stable. Glucagon increases energy expenditure and is elevated under conditions of stress. Glucagon is a amino acid polypeptide. The polypeptide has a molecular mass of daltons. The hormone is synthesized and secreted from alpha cells α-cells of the islets of Langerhans , which are located in the endocrine portion of the pancreas. Glucagon is produced from the preproglucagon gene Gcg. Preproglucagon first has its signal peptide removed by signal peptidase , forming the amino acid protein proglucagon. In intestinal L cells , proglucagon is cleaved to the alternate products glicentin 1—69 , glicentin-related pancreatic polypeptide 1—30 , oxyntomodulin 33—69 , glucagon-like peptide 1 72— or , and glucagon-like peptide 2 — In rodents, the alpha cells are located in the outer rim of the islet. Human islet structure is much less segregated, and alpha cells are distributed throughout the islet in close proximity to beta cells. Glucagon is also produced by alpha cells in the stomach. Recent research has demonstrated that glucagon production may also take place outside the pancreas, with the gut being the most likely site of extrapancreatic glucagon synthesis. Glucagon generally elevates the concentration of glucose in the blood by promoting gluconeogenesis and glycogenolysis. Glucose is stored in the liver in the form of the polysaccharide glycogen, which is a glucan a polymer made up of glucose molecules. Liver cells hepatocytes have glucagon receptors. When glucagon binds to the glucagon receptors, the liver cells convert the glycogen into individual glucose molecules and release them into the bloodstream, in a process known as glycogenolysis. As these stores become depleted, glucagon then encourages the liver and kidney to synthesize additional glucose by gluconeogenesis. Glucagon turns off glycolysis in the liver, causing glycolytic intermediates to be shuttled to gluconeogenesis. Glucagon also regulates the rate of glucose production through lipolysis. Glucagon induces lipolysis in humans under conditions of insulin suppression such as diabetes mellitus type 1. Glucagon production appears to be dependent on the central nervous system through pathways yet to be defined. In invertebrate animals , eyestalk removal has been reported to affect glucagon production. Excising the eyestalk in young crayfish produces glucagon-induced hyperglycemia. Glucagon binds to the glucagon receptor , a G protein-coupled receptor , located in the plasma membrane of the cell. The conformation change in the receptor activates a G protein , a heterotrimeric protein with α s , β, and γ subunits. When the G protein interacts with the receptor, it undergoes a conformational change that results in the replacement of the GDP molecule that was bound to the α subunit with a GTP molecule. The alpha subunit specifically activates the next enzyme in the cascade, adenylate cyclase. Adenylate cyclase manufactures cyclic adenosine monophosphate cyclic AMP or cAMP , which activates protein kinase A cAMP-dependent protein kinase. This enzyme, in turn, activates phosphorylase kinase , which then phosphorylates glycogen phosphorylase b PYG b , converting it into the active form called phosphorylase a PYG a. Phosphorylase a is the enzyme responsible for the release of glucose 1-phosphate from glycogen polymers. An example of the pathway would be when glucagon binds to a transmembrane protein. The transmembrane proteins interacts with Gɑβ𝛾. Gαs separates from Gβ𝛾 and interacts with the transmembrane protein adenylyl cyclase. Adenylyl cyclase catalyzes the conversion of ATP to cAMP. cAMP binds to protein kinase A, and the complex phosphorylates glycogen phosphorylase kinase. Phosphorylated glycogen phosphorylase clips glucose units from glycogen as glucose 1-phosphate. Additionally, the coordinated control of glycolysis and gluconeogenesis in the liver is adjusted by the phosphorylation state of the enzymes that catalyze the formation of a potent activator of glycolysis called fructose 2,6-bisphosphate. This covalent phosphorylation initiated by glucagon activates the former and inhibits the latter. This regulates the reaction catalyzing fructose 2,6-bisphosphate a potent activator of phosphofructokinase-1, the enzyme that is the primary regulatory step of glycolysis [24] by slowing the rate of its formation, thereby inhibiting the flux of the glycolysis pathway and allowing gluconeogenesis to predominate. This process is reversible in the absence of glucagon and thus, the presence of insulin. Glucagon stimulation of PKA inactivates the glycolytic enzyme pyruvate kinase , [25] inactivates glycogen synthase , [26] and activates hormone-sensitive lipase , [27] which catabolizes glycerides into glycerol and free fatty acid s , in hepatocytes. Malonyl-CoA is a byproduct of the Krebs cycle downstream of glycolysis and an allosteric inhibitor of Carnitine palmitoyltransferase I CPT1 , a mitochondrial enzyme important for bringing fatty acids into the intermembrane space of the mitochondria for β-oxidation. Thus, reduction in malonyl-CoA is a common regulator for the increased fatty acid metabolism effects of glucagon. Abnormally elevated levels of glucagon may be caused by pancreatic tumors , such as glucagonoma , symptoms of which include necrolytic migratory erythema , [30] reduced amino acids, and hyperglycemia. It may occur alone or in the context of multiple endocrine neoplasia type 1. Elevated glucagon is the main contributor to hyperglycemic ketoacidosis in undiagnosed or poorly treated type 1 diabetes. As the beta cells cease to function, insulin and pancreatic GABA are no longer present to suppress the freerunning output of glucagon. As a result, glucagon is released from the alpha cells at a maximum, causing a rapid breakdown of glycogen to glucose and fast ketogenesis. The absence of alpha cells and hence glucagon is thought to be one of the main influences in the extreme volatility of blood glucose in the setting of a total pancreatectomy. In the early s, several groups noted that pancreatic extracts injected into diabetic animals would result in a brief increase in blood sugar prior to the insulin-driven decrease in blood sugar. Kimball and John R. Murlin identified a component of pancreatic extracts responsible for this blood sugar increase, terming it "glucagon", a portmanteau of " gluc ose agon ist". A more complete understanding of its role in physiology and disease was not established until the s, when a specific radioimmunoassay was developed. Contents move to sidebar hide. Article Talk.
