A nodular organ in the ABDOMEN that contains a mixture of ENDOCRINE GLANDS and EXOCRINE GLANDS. The small endocrine portion consists of the ISLETS OF LANGERHANS secreting a number of hormones into the blood stream. The large exocrine portion (EXOCRINE PANCREAS) is a compound acinar gland that secretes several digestive enzymes into the pancreatic ductal system that empties into the DUODENUM.
The transference of a pancreas from one human or animal to another.
The major component (about 80%) of the PANCREAS composed of acinar functional units of tubular and spherical cells. The acinar cells synthesize and secrete several digestive enzymes such as TRYPSINOGEN; LIPASE; AMYLASE; and RIBONUCLEASE. Secretion from the exocrine pancreas drains into the pancreatic ductal system and empties into the DUODENUM.
Tumors or cancer of the PANCREAS. Depending on the types of ISLET CELLS present in the tumors, various hormones can be secreted: GLUCAGON from PANCREATIC ALPHA CELLS; INSULIN from PANCREATIC BETA CELLS; and SOMATOSTATIN from the SOMATOSTATIN-SECRETING CELLS. Most are malignant except the insulin-producing tumors (INSULINOMA).
Pathological processes of the PANCREAS.
Ducts that collect PANCREATIC JUICE from the PANCREAS and supply it to the DUODENUM.
Devices for simulating the activity of the pancreas. They can be either electromechanical, consisting of a glucose sensor, computer, and insulin pump or bioartificial, consisting of isolated islets of Langerhans in an artificial membrane.
INFLAMMATION of the PANCREAS. Pancreatitis is classified as acute unless there are computed tomographic or endoscopic retrograde cholangiopancreatographic findings of CHRONIC PANCREATITIS (International Symposium on Acute Pancreatitis, Atlanta, 1992). The two most common forms of acute pancreatitis are ALCOHOLIC PANCREATITIS and gallstone pancreatitis.
Irregular microscopic structures consisting of cords of endocrine cells that are scattered throughout the PANCREAS among the exocrine acini. Each islet is surrounded by connective tissue fibers and penetrated by a network of capillaries. There are four major cell types. The most abundant beta cells (50-80%) secrete INSULIN. Alpha cells (5-20%) secrete GLUCAGON. PP cells (10-35%) secrete PANCREATIC POLYPEPTIDE. Delta cells (~5%) secrete SOMATOSTATIN.

Ultrasonography of internal organs using an ultrasound transducer sometimes mounted on a fiberoptic endoscope. In endosonography the transducer converts electronic signals into acoustic pulses or continuous waves and acts also as a receiver to detect reflected pulses from within the organ. An audiovisual-electronic interface converts the detected or processed echo signals, which pass through the electronics of the instrument, into a form that the technologist can evaluate. The procedure should not be confused with ENDOSCOPY which employs a special instrument called an endoscope. The "endo-" of endosonography refers to the examination of tissue within hollow organs, with reference to the usual ultrasonography procedure which is performed externally or transcutaneously.

Cholecystokinin receptors are activated by GASTRIN as well as by CCK-4; CCK-8; and CCK-33. Activation of these receptors evokes secretion of AMYLASE by pancreatic acinar cells, acid and PEPSIN by stomach mucosal cells, and contraction of the PYLORUS and GALLBLADDER. The role of the widespread CCK receptors in the central nervous system is not well understood.
A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

Determination of human body burden baseline date of platinum through autopsy tissue analysis. (1/8132)

Results of analysis for platinum in 97 autopsy sets are presented. Analysis was performed by a specially developed emission spectrochemical method. Almost half of the individuals studied were found to have detectable platinum in one or more tissue samples. Platinum was found to be deposited in 13 of 21 tissue types investigated. Surprisingly high values were observed in subcutaneous fat, previously not considered to be a target site for platinum deposition. These data will serve as a human tissue platinum burden baseline in EPA's Catalyst Research Program.  (+info)

Tissue-specific knockout of the insulin receptor in pancreatic beta cells creates an insulin secretory defect similar to that in type 2 diabetes. (2/8132)

Dysfunction of the pancreatic beta cell is an important defect in the pathogenesis of type 2 diabetes, although its exact relationship to the insulin resistance is unclear. To determine whether insulin signaling has a functional role in the beta cell we have used the Cre-loxP system to specifically inactivate the insulin receptor gene in the beta cells. The resultant mice exhibit a selective loss of insulin secretion in response to glucose and a progressive impairment of glucose tolerance. These data indicate an important functional role for the insulin receptor in glucose sensing by the pancreatic beta cell and suggest that defects in insulin signaling at the level of the beta cell may contribute to the observed alterations in insulin secretion in type 2 diabetes.  (+info)

Freeze-fracture replication of organized tissue without cryoprotection. (3/8132)

Fresh pieces of rat liver and pancreas were rapidly frozen without prior chemical fixation or cryoprotection, and replicated folloing freeze-fracture. Replicas revealed small peripheral areas free of ice crystals or damage and, within such areas, general ultrastructural morphology was essentially similar to that seen in conventionally processed material. On fracture faces of plasma and nuclear membranes a population of less prominent particles in addition to conventional membrane-associated particles was seen, and smooth areas devoid of particles of any type were seen on some nuclear membranes. These smooth areas did not appear to be similar to smooth areas allegedly arising as artifacts of conventional processing. Tight junctions and gap junctions appeared as they do in cryoprotected specimens. The results provide a base-line for assessing the possible effects of processing steps or agents on the ultrastructure of organized tissues as revealed in freeze-fracture replicas.  (+info)

Further studies on the mechanism of adrenaline-induced lipolysis in lipid micelles. (4/8132)

Lipase [EC] depleted lipid micelles, in which lipolysis was not elicited by adrenaline, were prepared from lipid micelles. When these lipase-depleted lipid micelles incubated with adipose tissue extract containing lipase activity, adrenaline-induced lipolysis was restored to almost the same level as that of native lipid micelles. Adrenaline-induced lipolysis was not restored when the lipase-depleted lipid micelles were homogenized or sonicated. Various tissue extracts from kidney, lung, liver, and pancreas, and post-heparin plasma, which contained lipase activity, restored adrenaline-induced lipolysis in lipase-depleted lipid micelles.  (+info)

Efficient binding of regulated secretory protein aggregates to membrane phospholipids at acidic pH. (5/8132)

Some regulated secretory proteins are thought to be targeted to secretory granules through an acidic-dependent aggregation in the trans-Golgi network. In this report we use pancreatic zymogens, a paradigm of regulated proteins, to test this hypothesis, because they qualitatively aggregate upon acidification in vitro. Pig zymogens were found to start to aggregate significantly at pH approximately 6.0, a pH slightly lower than that at which rat zymogens aggregate, but still compatible with the pH of the cell-sorting compartments. When pig zymogen granule membranes were mixed with the zymogens in the aggregation assay, membranes that normally floated on 1 M sucrose were observed to be pelleted by the aggregating zymogens. Rat membranes were pelleted by pig zymogens and vice versa. Igs, typical constitutively secreted proteins, which needed chemical cross-linking to serve as an aggregated protein control, pelleted membranes almost independently of pH. Corresponding cross-linked zymogen-binding ability and pH dependence was unaffected by the chemical modification. Membranes treated with sodium carbonate, pH 11, or with protease K, were still pelleted by zymogens, suggesting that the aggregated zymogens bound to membrane lipids. This hypothesis was confirmed by the efficient pelleting of unilamellar vesicles composed of granule membrane lipids. Vesicles composed of single classes of phospholipids were also pelleted, but with various efficacies. We conclude that pancreatic zymogen aggregates, formed under the acidic conditions of the secretory pathway sorting compartments, have the capacity to bind firmly to membranes through their phospholipid constituents.  (+info)

His ... Asp catalytic dyad of ribonuclease A: histidine pKa values in the wild-type, D121N, and D121A enzymes. (6/8132)

Bovine pancreatic ribonuclease A (RNase A) has a conserved His ... Asp catalytic dyad in its active site. Structural analyses had indicated that Asp121 forms a hydrogen bond with His119, which serves as an acid during catalysis of RNA cleavage. The enzyme contains three other histidine residues including His12, which is also in the active site. Here, 1H-NMR spectra of wild-type RNase A and the D121N and D121A variants were analyzed thoroughly as a function of pH. The effect of replacing Asp121 on the microscopic pKa values of the histidine residues is modest: none change by more than 0.2 units. There is no evidence for the formation of a low-barrier hydrogen bond between His119 and either an aspartate or an asparagine residue at position 121. In the presence of the reaction product, uridine 3'-phosphate (3'-UMP), protonation of one active-site histidine residue favors protonation of the other. This finding is consistent with the phosphoryl group of 3'-UMP interacting more strongly with the two active-site histidine residues when both are protonated. Comparison of the titration curves of the unliganded enzyme with that obtained in the presence of different concentrations of 3'-UMP shows that a second molecule of 3'-UMP can bind to the enzyme. Together, the data indicate that the aspartate residue in the His ... Asp catalytic dyad of RNase A has a measurable but modest effect on the ionization of the adjacent histidine residue.  (+info)

Characterization of functional residues in the interfacial recognition domain of lecithin cholesterol acyltransferase (LCAT). (7/8132)

Lecithin cholesterol acyltransferase (LCAT) is an interfacial enzyme active on both high-density (HDL) and low-density lipoproteins (LDL). Threading alignments of LCAT with lipases suggest that residues 50-74 form an interfacial recognition site and this hypothesis was tested by site-directed mutagenesis. The (delta56-68) deletion mutant had no activity on any substrate. Substitution of W61 with F, Y, L or G suggested that an aromatic residue is required for full enzymatic activity. The activity of the W61F and W61Y mutants was retained on HDL but decreased on LDL, possibly owing to impaired accessibility to the LDL lipid substrate. The decreased activity of the single R52A and K53A mutants on HDL and LDL and the severer effect of the double mutation suggested that these conserved residues contribute to the folding of the LCAT lid. The membrane-destabilizing properties of the LCAT 56-68 helical segment were demonstrated using the corresponding synthetic peptide. An M65N-N66M substitution decreased both the fusogenic properties of the peptide and the activity of the mutant enzyme on all substrates. These results suggest that the putative interfacial recognition domain of LCAT plays an important role in regulating the interaction of the enzyme with its organized lipoprotein substrates.  (+info)

Cloning and characterization of a secreted frizzled-related protein that is expressed by the retinal pigment epithelium. (8/8132)

The Wnt/frizzled cell signaling pathway has been implicated in the determination of polarity in a number of systems, including the Drosophila retina. The vertebrate retina develops from an undifferentiated neuroepithelium into an organized and laminated structure that demonstrates a high degree of polarity at both the tissue and cellular levels. In the process of searching for molecules that are preferentially expressed by the vertebrate retinal pigment epithelium (RPE), we identified secreted frizzled-related protein 5 (SFRP5), a member of the SFRP family that appears to act by modulating Wnt signal transduction. SFRP5 is highly expressed by RPE cells, and is also expressed in the pancreas. Within the retina, the related molecule SFRP2 is expressed specifically by cells of the inner nuclear layer. Thus, photoreceptors are likely to be bathed by two opposing gradients of SFRP molecules. Consistent with SFRP5 's postulated role in modulating Wnt signaling in the retina, it inhibits the ability of Xwnt-8 mRNA to induce axis duplication in Xenopus embryos. The human SFRP5 gene consists of three coding exons and it maps to chromosome 10q24.1; human SFRP2 maps to 4q31.3. Based on the biology and complementary expression patterns of SFRP2 and SFRP5, we suggest that they may be involved in determining the polarity of photoreceptor, and perhaps other, cells in the retina.  (+info)

We have previously demonstrated [M. Campos-Toimil, T. Bagrij, J.M. Edwardson, P. Thomas, Two modes of secretion in pancreatic acinar cells: involvement of phosphatidylinositol 3-kinase and regulation by capacitative Ca2+ entry, Curr. Biol. 12 (2002) 211-215] that in rat pancreatic acinar cells, Gd3+-sensitive Ca2+ entry is instrumental in governing which second messenger pathways control secretory activity. However, in those studies, we were unable to demonstrate a significant increase in cytoplasmic [Ca2+] during agonist application as a result of this entry pathway. In the present study, we combined pharmacology with ratiometric imaging of fura-2 fluorescence to resolve this issue. We found that 2 μM Gd3+ significantly inhibits store-mediated Ca2+ entry. Furthermore, both the protonophore, CCCP (5 μM) and the mitochondrial Ca2+-uptake blocker, RU360 (10 μM), led to an enhancement of the plateau phase of the biphasic Ca2+ response induced by acetylcholine (1 μM). This enhancement was ...
Hedgehog (Hh) signaling regulates cell proliferation and differentiation in various organs during embryogenesis. In the pancreas, the role of this pathway is complex. At early stages, Hh signaling is excluded from the pancreas and ectopic activation of the pathway impairs pancreas formation by disturbing mesenchymal-epithelial interactions. In contrast to this inhibitory role, our preliminary data suggest a positive, cell autonomous role for Hh signaling during endocrine cell formation and function. The exact nature of this novel, cell autonomous activity remains to be elucidated. Little information is also available about the upstream mechanisms that regulate Hh signaling in pancreatic epithelium. Recent results have revealed that primary cilia, cellular appendages found on many cell types, control the level of Hh signaling activity. Primary cilia are present on adult duct and endocrine cells within the pancreas, the same cell types that are marked by expression of Ptc, a transcriptional target ...
Pancreatic Stem Cells Found in Adult Mice Thursday, 24 January 2008 Just as many scientists had given up the search, researchers have discovered that the pancreas does indeed harbour stem cells with the capacity to generate new insulin-producing beta cells. If the finding made in adult mice holds for humans, the newfound progenitor cells will represent an obvious target for therapeutic regeneration of beta cells in diabetes, the researchers report in the Jan. 25 issue of Cell, a publication of Cell Press. One of the most interesting characteristics of these [adult] progenitor cells is that they are almost indistinguishable from embryonic progenitors, said Harry Heimberg of the JDRF Center at Vrije Universiteit Brussel in Belgium and the JDRF Center for Beta Cell Therapy in Diabetes. In terms of their structure and gene expression, there are no major differences. They look and behave just like embryonic beta cell progenitors. Insulin is required for cells to take up blood sugar, the bodys ...
Accessory pancreas is a rare condition in which small groups of pancreatic cells are separate from the pancreas. They may occur in the mesentery of the small intestine, the wall of the duodenum, the upper part of the jejunum, or more rarely, in the wall of the stomach, ileum, gallbladder or spleen. The condition was first described by Klob in 1859. Accessory pancreas is a small cluster of pancreas cells detached from the pancreas and sometimes found in the wall of the stomach or intestines. After researching accessory pancreas at the University of Louisville medical library, I found a list of medical cases and the doctors that operated on the patients with this condition. In 1904, Dr. A. S. Warthin found 47 cases in the literature and added 2. Up to 1921, 31 cases were added. Twelve cases were found at operation. A number of patients have been operated upon for this trouble since then. E. J. Horgan found 2 cases in 321 consecutive autopsies. Locality of Accessory Pancreas, A. S. Warthin, 1904: ...

Chronic pancreatitis is an inflammatory disease of the exocrine pancreas characterised by the replacement of pancreatic parenchyma by fibrosis.1 2 Apart from fibrosis, the pancreatic parenchyma may also exhibit enlarged ducts, infiltration by inflammatory cells, the formation of duct-like tubular complexes, regions of acinar cell degeneration, and duct cell proliferation.3 In human acute and chronic pancreatitis, pancreatic cancer, and animal models of acute pancreatitis, duct-like structures, referred to as tubular complexes, have been described.4 8 Tubular complexes evolve as the acinar cells decrease in height and lose acinar cell specific antigens, paralleled by increased expression of duct cell markers.9 39 The molecular alterations underlying the fibrotic changes and the formation of these duct-like complexes are largely unknown. Recently, tyrosine kinase receptors, comprising the large family of growth factor receptors, have been shown to be overexpressed in the pancreas of patients with ...

article{6854376, abstract = {Expansion of pancreatic beta cells in vivo or ex vivo, or generation of beta cells by differentiation from an embryonic or adult stem cell, can provide new expandable sources of beta cells to alleviate the donor scarcity in human islet transplantation as therapy for diabetes. Although recent advances have been made towards this aim, mechanisms that regulate beta cell expansion and differentiation from a stem/progenitor cell remain to be characterized. Here, we describe a protocol for an injury model in the adult mouse pancreas that can function as a tool to study mechanisms of tissue remodeling and beta cell proliferation and differentiation. Partial duct ligation (PDL) is an experimentally induced injury of the rodent pancreas involving surgical ligation of the main pancreatic duct resulting in an obstruction of drainage of exocrine products out of the tail region of the pancreas. The inflicted damage induces acinar atrophy, immune cell infiltration and severe ...

TY - CHAP. T1 - Differentiation of pancreatic cells into hepatocytes. AU - Tosh, D. PY - 2006. Y1 - 2006. N2 - This chapter describes the use of the pancreatic cell line AR42J and mouse embryonic pancreas as models for the trans-differentiation of pancreas to liver. Both AR42J cells and embryonic pancreas can be induced to trans-differentiate to hepatocytes by exposure to the glucocorticoid dexamethasone. Dexamethasone can be replaced by the naturally occurring glucocorticoid cortisol to induce the conversion of AR42J cells to hepatocytes. To determine whether the effect of the glucocorticoid is specific, the cells can be exposed to RU486, the glucocorticoid receptor antagonist, prior to the addition of dexamethasone or cortisol. Because the embryonic pancreas contains both exocrine and endocrine cell types, it is possible, with the correct combination of antibodies, to immunostain for at least three cell types. AR42J cells can be obtained as a frozen aliquot or growing culture from the ECACC ...

WEDNESDAY, Oct. 21, 2020 (HealthDay News) -- Scientists knew that dangerous T-cells lived in the pancreases of people with type 1 diabetes, but a new study shows they also take up residence in the pancreases of healthy individuals.. Researchers from the La Jolla Institute for Immunology in California used a new staining technique to show where these cells had gathered in human tissue samples. They were surprised that even tissue from healthy people showed these cells in high numbers in the pancreas.. Whats the difference? Even though healthy people have these immune system cells, people with type 1 diabetes have T-cells that are close to or infiltrate cell clusters inside the pancreas. Beta cells that live in these clusters make insulin to regulate blood sugar, but in people with type 1 diabetes the T-cells kill those beta cells.. These T-cells are like predators, said senior study author Dr. Matthias von Herrath, from the La Jolla Institute. And we always thought that beta cells would die ...
We show here that during pancreas development, blood vessels restrain pancreas tip cell formation and branching morphogenesis, and antagonize differentiation of epithelial cells into exocrine and endocrine fates. Consequently, the surprising net effect of blood vessels on pancreas development is inhibition of growth and a restriction of final organ size. The signals that mediate this response are independent of blood flow, circulating plasma factors and the provision of nutrients and oxygen, as manipulations of the vasculature lead to similar effects in vivo and in explants cultured in complete medium and ambient oxygen.. These findings seem counterintuitive and run against the well-established notion that blood vessels are positive regulators of tissue growth during development and postnatal life, as well as in pathologies such as cancer. How can our results be reconciled with this view? More specifically, how do our findings fit into the current understanding of pancreas development and ...

The mammalian pancreas is a compound gland of endocrine and exocrine tissues derived from the embryonic endoderm (62). Approximately 90% of the pancreas is exocrine tissue, comprising acinar cells that synthesize and secrete digestive enzymes and ductal cells that secrete and channel the fluid that transports the acinar enzymes to the duodenum. About 1% of the pancreas is endocrine tissue, comprising four principal cell types synthesizing insulin (β-cells), glucagon (α-cells), somatostatin (δ-cells), and pancreatic polypeptide (PP cells) organized into islets scattered throughout the exocrine pancreas. The endocrine and exocrine compartments are structurally and functionally integrated through an islet-acinar portal blood system that facilitates the regulation of acinar cell functions directly by islet peptide hormones (81).. The exocrine-endocrine relationship begins at the inception of pancreogenesis: both tissues are derived from a common endodermal cell lineage (for reviews, see ...
Mesenchyme. Coalescence of the mesenchyme at the level where the dorsal pancreas will form is the first morphological sign of pancreatic development. Removal of the mesoderm, or the fibroblasts within the mesoderm, prior to pancreatic specification results in pancreatic agenesis (53, 107, 164). Mesoderm removal following specification results in a reduction of the total pancreatic size indicating an ongoing requirement for mesoderm signaling to attain complete organ development (94). Interestingly, culturing of pancreatic mesenchyme with other sections of the dorsal endoderm can promote pancreatic differentiation, while mesenchyme from other regions of the anterior-posterior axis does not have this ability (10). This suggests that the mesenchyme provides signals that promote pancreatic specification, yet limits differentiation, thereby allowing expansion of the organ. These signals come in a variety of sources.. Physical interactions between the mesoderm and developing pancreatic bud affect ...
We were quite surprised to find cellular structures that are essentially as old as the organism they reside in, says Salk Vice President, Chief Science Officer Martin Hetzer, senior author and professor. This suggests even greater cellular complexity than we previously imagined and has intriguing implications for how we think about the aging of organs, such as the brain, heart and pancreas. Most neurons in the brain do not divide during adulthood and thus experience a long lifespan and age-related decline. Yet, largely due to technical limitations, the lifespan of cells outside of the brain was difficult to determine. Isotope imaging of different cells inside an islet of Langerhans within the pancreas. Older cells have a yellow-to-pink color scheme, while younger cells exhibit a blue-to-green color pattern. Isotope imaging of different cells inside an islet of Langerhans within the pancreas.

Breaks down nutrients and makes hormones. The pancreas does two main things. It makes fluids that contain enzymes, which break down the nutrients in food - like fats and proteins - so your body can use them. And it makes hormones like insulin to balance your blood sugar levels. Where is the pancreas located? Behind the stomach. The pancreas is about 6 inches long and looks a bit like a tadpole, with a head, body, and tail. It sits in the abdomen, behind the stomach and in front of the spine. What does your pancreas make? Enzymes. Enzymes are proteins that boost the rate of chemical reactions in your body. Without them, processes that can take seconds or minutes would take years. Enzymes in the pancreas combine with bile, a liquid made by the liver, to break down food. You can live without a pancreas. True. Because the pancreas makes insulin, youll develop diabetes if you need to have yours removed. That means you will be dependent on insulin shots (or a pump). Its also hard to manage because ...
Objective: Pancreas organogenesis is orchestrated by interactions between the epithelium and the mesenchyme, but these interactions are incompletely understood. Here we investigated a role for BMP signalling within the pancreas mesenchyme and found it to be required for the normal development of the mesenchyme as well as the pancreatic epithelium.. Research Design and Methods: We analysed active BMP signalling by immunostaining for phospho-Smad1,5,8 and tested whether pancreas development was affected by BMP inhibition after expression of Noggin and dominant negative BMP receptors in chicken and mouse pancreas.. Results: Endogenous BMP signalling is confined to the mesenchyme in the early pancreas and inhibition of BMP signalling results in severe pancreatic hypoplasia with reduced epithelial branching. Notably, we also observe an excessive endocrine differentiation when mesenchymal BMP signalling is blocked, presumably secondary to defective mesenchyme to epithelium signalling.. Conclusions: We ...
2. Activation of ERK pathway in Pancreatic Acinar Cells (Figure 1). ERK activation is usually monitored by following the dual phosphorylation of the Thr and Tyr residues in the Thr-Glu-Tyr activation sequence brought about by MEK as there are a number of good phosphospecific antibodies directed at this epitope. It can also be shown by phosphorylation of myelin basic protein either in a test tube or by an in gel technique following gel electrophoresis and renaturization. Both Western blots and the in gel kinase procedure reveal the two forms of ERK at approximately 44 and 42 kDa; in fact, the molecules were originally referred to as p42 and p44 MAPK with p42 being what is now referred to as ERK2 and p44 now being ERK1. Using isolated rat or mouse pancreatic acini in vitro, ERK1/2 is activated by CCK, bombesin, substance P, and carbachol, all of which activate G protein coupled receptors coupled to Gq and calcium mobilization but not by secretin or VIP which activate receptors coupled to Gs and ...

The pancreatic acinar cell is perhaps the best studied such cell, and the classical model for stimulus-secretion coupling and secretory protein biosynthesis and export. In this review, I examine several new reports that impact on these themes. I include the identification of newly recognized pancreatic secretagogues; insights into the biochemical basis for hormone receptor affinity states and interconversion, desensitization, and internalization; lipid mediators of secretagogue action; patterns and regulators of intracellular calcium events along with their spatial and temporal patterns; regulated channels, transporters, and junctional communication in the acinar cell and cellular organelles; and new insights into regulated ...

Cystic tumors of the pancreas today are diagnosed more frequently in clinical practice, mainly due to an increased use of the modern advanced imaging modalities.. Bland cysts of the pancreas most often develop after chronic or acute inflammation of the pancreas. However, the current knowledge concerning the development of cystic neoplasias of the pancreas is still rudimentary.. Histopathologically, 90% of pancreatic cystic neoplasias are represented by four types: serous microcystic (SCN), mucinous cystic (MCN), intraductal papillary mucinous (IPMN) and solid pseudopapillary (SPN) neoplasias. Surgical treatment of these lesions can be highly challenging and occasionally demands complex surgical approaches that should be put in the hands of skilled pancreatic surgeons in experienced high-volume centers.. While some of the described cystic tumors are harmless, such as SCNs of the pancreas, others such as IPMN and MCN harbor relevant malignant potential. The differential diagnosis of these lesions ...
The pancreas is a dual function organ contributing to both blood glucose homeostasis and digestion. These functions are carried out by the endocrine and exocrine compartments of the pancreas, respectively, which derive from common multipotent progenitor cells (MPCs) during embryonic development. The differentiation process for the cells composing both the endocrine and exocrine compartments is highly orchestrated by regulatory transcription factors. Previous work from our lab showed that one such factor, Onecut 1 (Oc1), is essential for initiating endocrine development, proper duct development, and appears necessary for acinar cell development. Using gene expression and physiologic analyses of genetically altered mouse models we have determined that threshold-dependent cooperation between Oc1 and another transcription factor, Pancreatic and duodenal homeobox 1 (Pdx1) in MPCs is necessary for proper endocrine specification, differentiation, maturation, and function. Additionally, we have ...

The pancreas performs both exocrine and endocrine functions. The exocrine pancreas consists of two parts, the acinar and duct cells. The primary functions of pancreatic acinar cells are to synthesize and secrete digestive enzymes. Stimulation of the cell by secretagogues such as acetylcholine (ACh) and cholecystokinin (CCK) causes the generation of an intracellular Ca2+ signal. This signal, in turn, triggers the fusion of the zymogen granules with the apical plasma membrane, leading to the polarised secretion of the enzymes. The major task of pancreatic duct cells is the secretion of fluid and bicarbonate ions (HCO3-), which neutralize the acidity of gastric contents that enter the duodenum. An increase in intracellular cAMP by secretin is one of the major signals of pancreatic HCO3- secretion. Activation of the CFTR Cl- channel and the CFTR-dependent Cl-/HCO3- exchange activities is responsible for cAMP-induced HCO3- secretion ...
To understand the development of the human pancreas better, we studied the expression and regulation of insulin, insulin-like growth factor-II (IGF-II) and transforming growth factor-α (TGF-α) genes in the human fetal pancreas and islet-like cell clusters (ICC) from the second trimester human fetuses. Northern blot analysis revealed an abundant expression of IGF-II, insulin and TGF-α mRNAs in the intact pancreas and the cultured ICCs. Furthermore, transcripts for insulin receptor, type-1 and -2 IGF receptors, and GH receptor could be amplified by polymerase chain reaction analysis from the pancreas and the ICCs. With in-situ hybridization, IGF-II mRNA was found in abundance in both the exocrine and endocrine pancreas, exceeding the amount of insulin mRNA. In ICCs, insulin mRNA-containing cells were present as small clusters in the periphery and in the centre of the clusters corresponding to the immunolocation of insulin. The ICCs also contained many epidermal growth factor-, insulin- and ...
A 58-kD cis-Golgi protein has been identified by generating polyclonal antibodies against heavy (cis) Golgi subfractions. Total microsomes isolated from rat pancreatic homogenates were subfractionated to yield a rough microsomal fraction (B1) and three smooth membrane subfractions (B2-B4) enriched in cis-, middle, and trans-Golgi elements, respectively. The heavy (cis) subfraction, B2 (d = 1.17 g/ml), was fractionated by Triton X-114 phase separation, and the proteins recovered in the detergent phase were used to immunize rabbits. One of the anti-B2 antibodies obtained gave a Golgi-staining pattern when screened by immunofluorescence on normal rat kidney cells and mouse RPC 5.4 myeloma cells. In rat pancreatic exocrine cells the antibody reacted with the plasmalemma as well as elements in the Golgi region. By immunoelectron microscopy, the antigen recognized by anti-B2 IgG was found to be restricted to cis-Golgi elements in myeloma cells where it was concentrated in the fenestrated cis-most ...

The pancreas is in the very back of the upper abdomen, in front of the second lumbar vertebra and comprises three parts: the head, body and tail. Pancreatic enzymes are very important for digestion, but also regulate the blood sugar level by producing insulin.. Pancreatitis or inflammation of the pancreas develops in 90% of cases due to gallstones or excessive alcohol consumption. Bile sludge and small gallstones can reach the main bile duct and impede the flow of bile and pancreatic juice. The treatment is choice is elimination of these problems, as they act as trigger mechanisms for the development of pancreatitis.. Both benign and malignant tumors can develop in the pancreas. Benign tumors include cysts, cystadenomas and hormone-producing tumors that, however, can become malignant. Pancreatic carcinoma is one of the most aggressive kinds of cancer. Tumors should be diagnosed as soon as possible and treated appropriately according to their stage. Tumors in the tail and body of the pancreas in ...

GATA4 and GATA6 play essential, but redundant, roles in pancreas formation in mice and GATA6 mutations cause pancreatic agenesis in humans. Recently, GATA6 mutations have also been linked to adult-onset diabetes with subclinical or no exocrine insufficiency suggesting an important role for GATA6 in human ß cell physiology. To investigate the role of GATA6 in adult endocrine pancreas, we generated mice in which Gata6 is specifically inactivated in the pancreas. These mice develop glucose intolerance. Islets deficient in GATA6 activity display decreased insulin content and impaired insulin secretion. Gata6-deficient ß cells exhibit ultrastructural abnormalities including increased immature insulin granules, swollen mitochondria and disorganized endoplasmic reticulum. We also demonstrate that Pdx1 expression in adult ß cells depends on GATA sites in transgenic reporter mice and loss of GATA6 greatly impacts ß cell specific gene expression. These findings demonstrate the essential role of GATA6 ...

Cells need to find ways of surviving when times are hard. One way of dealing with nutrient scarcity is to digest intracellular constituents, providing a source of amino acids that can be used to synthesize proteins that are essential for survival (1). This process of autophagy (2), however, poses a problem for the bodys specialized fuel-sensing cells. β cells within the pancreatic islet respond to blood glucose concentration-when it rises after a meal, these cells release insulin; otherwise, under basal conditions (between meals), the cells are in a "starvation"-like state (3). So how do they maintain a normal turnover of intracellular components during this metabolic deprivation? Why dont they eat themselves as other cells would? At the very least, autophagy under basal conditions could compromise the ability to respond optimally to fluctuations in blood glucose, posing a health risk. On page 878 of this issue, Goginashvili et al. (4) show how β cells avoid inappropriate autophagy, and ...
