Immunoreactive pancreatic Reg protein in sera from cystic fibrosis patients with and without pancreatic insufficiency. (1/124)

BACKGROUND: The biological function of the Reg protein, a non-enzymic protein produced in fairly large amounts by pancreatic acinar cells, remains elusive. Its susceptibility to proteolysis leading to precipitation of the proteolysis product at neutral pH suggests that it could contribute to the protein plugging observed in cystic fibrosis (CF). AIMS: To study its behaviour in the serum of CF patients with or without pancreatic insufficiency and to compare it with that of other pancreatic secretory proteins. PATIENTS: 170 patients (93 with CF, 55 controls, and 22 with chronic pancreatitis) were studied. METHODS: Reg protein was measured using a specific enzyme immunoassay and its molecular form in CF sera was characterised by gel filtration. Molecular gene expression was investigated by dot-blot hybridisation. RESULTS: Reg protein was present in all CF sera studied from patients with or without pancreatic insufficiency, and in all cases the level was significantly higher than in controls. Its chromatographic behaviour in CF sera was identical with that of the protein present in normal serum. No correlation was found between the levels of Reg protein and trypsin(ogen) (or lipase) in CF, nor in control sera or normal pancreatic juice. Molecular gene expression of the corresponding proteins investigated in pancreatic tissues showed an absence of correlation between the mRNA levels. CONCLUSIONS: Reg protein may not be a secretory exocrine protein like the digestive enzymes but rather a hormone-like secretory substance with an endocrine or paracrine function.  (+info)

Temperature-jump studies on the interaction of benzeneboronic acid with chymotrypsinogen. (2/124)

The interaction of chymotrypsinogen A with benzeneboronic acid (BBA), a transition state along inhibitor of serine proteases, was investigated by the temperature-jump method using pH indicators. It was found that l/tau is dependent on BBA concentration, in contrast to the case of the alpha-chymotrypsin [EC 3.4.21.1]-BBA system in which l/tau is independent of BBA concentration. By examination of the pH dependences of the kinetic parameters, the acid dissociation behavior of His 57 in chymotrypsinogen, chymotrypsinogen-trigonal BBA complex and chymotrypsinogen-tetrahedral BBA complex was analyzed. The kinetic deuterium isotope effect was also examined and found to occur principally on the acid dissociation constants. The state of the catalytic residues in the zymogen molecule is discussed based on these results.  (+info)

Pancreatic function in CCK-deficient mice: adaptation to dietary protein does not require CCK. (3/124)

A CCK-deficient mouse mutant generated by gene targeting in embryonic stem cells was analyzed to determine the importance of CCK for growth and function of the exocrine pancreas and for pancreatic adaptation to dietary changes. RIAs confirmed the absence of CCK in mutant mice and demonstrated that tissue concentrations of the related peptide gastrin were normal. CCK-deficient mice are viable and fertile and exhibit normal body weight. Pancreas weight and cellular morphology appeared normal, although pancreatic amylase content was elevated in CCK-deficient mice. We found that a high-protein diet increased pancreatic weight, protein, DNA, and chymotrypsinogen content similarly in CCK-deficient and wild-type mice. This result demonstrates that CCK is not required for protein-induced pancreatic hypertrophy and increased proteolytic enzyme content. This is a novel finding, since CCK has been considered the primary mediator of dietary protein-induced changes in the pancreas. Altered somatostatin concentrations in brain and duodenum of CCK-deficient mice suggest that other regulatory pathways are modified to compensate for the CCK deficiency.  (+info)

Vesicular tubular clusters between the ER and Golgi mediate concentration of soluble secretory proteins by exclusion from COPI-coated vesicles. (4/124)

We have determined the concentrations of the secretory proteins amylase and chymotrypsinogen and the membrane proteins KDELr and rBet1 in COPII- and COPI-coated pre-Golgi compartments of pancreatic cells by quantitative immunoelectron microscopy. COPII was confined to ER membrane buds and adjacent vesicles. COPI occurred on vesicular tubular clusters (VTCs), Golgi cisternae, the trans-Golgi network, and immature secretory granules. Both secretory proteins exhibited a first, significant concentration step in noncoated segments of VTC tubules and were excluded from COPI-coated tips. By contrast, KDELr and rBet1 showed a first, significant concentration in COPII-coated ER buds and vesicles and were prominently present in COPI-coated tips of VTC tubules. These data suggest an important role of VTCs in soluble cargo concentration by exclusion from COPI-coated domains.  (+info)

Detection of the pancreas-specific gene in the peripheral blood of patients with pancreatic carcinoma. (5/124)

The prognosis of patients with pancreatic carcinoma remains very poor. To improve the therapeutic results, the early detection of this cancer is needed. The present study was performed to detect the pancreas-specific gene, chymotrypsinogen, in the peripheral blood from patients with pancreatic carcinoma by using reverse transcription polymerase chain reaction (RT-PCR) in order to evaluate the clinical significance of this gene. Ten patients with pancreatic carcinoma, two with acute pancreatitis, three with chronic pancreatitis and ten control subjects were examined for the presence of chymotrypsinogen using RT-PCR techniques in the peripheral blood. To confirm that the chymotrypsinogen gene was expressed in a pancreas-specific manner, the expression of chymotrypsinogen in various types of human adult tissue was evaluated by RT-PCR. The specific band of the chymotrypsinogen gene was detected in the pancreas. Serial dilution studies demonstrated the chymotrypsinogen gene to be detected at a concentration of one pancreatic cell per 10(6) peripheral blood cells. Seven out of the ten (70%) patients with pancreatic carcinoma were found to be positive based on the RT-PCR findings. In contrast, no pancreas-specific gene was detected in the peripheral blood of any patients with acute pancreatitis, chronic pancreatitis or the control subjects. Our observations show that the detection of the pancreatic specific gene, chymotrypsinogen, is therefore useful as a genetic diagnostic marker in pancreatic carcinoma.  (+info)

The CCKB/gastrin receptor is coupled to the regulation of enzyme secretion, protein synthesis and p70 S6 kinase activity in acinar cells from ElasCCKB transgenic mice. (6/124)

In order to determine which physiological functions can be regulated by the pancreatic CCKB/gastrin receptor, studies were carried out on pancreatic acini from mice expressing transgenic CCKB/gastrin receptors in the exocrine pancreas (ElasCCKB mice). Acini were stimulated by sulfated gastrin in the presence of SR 27897 (1.8 microM), blocking endogenous CCKA receptors. After 30 min incubation with gastrin, the secretion of chymotrypsinogen and amylase showed superimposable monophasic dose-response curves. Enzyme secretion was detectable and maximal at 100 pM and 1 nM of gastrin, respectively. No increase in chymotrypsinogen and amylase mRNAs was detected for doses of gastrin which specifically occupy the CCKB/gastrin receptor. In contrast, gastrin stimulated total protein synthesis in isolated acini from ElasCCKB mice. [35S]Methionine incorporation into total proteins was increased dose-dependently to a maximum for 30 pM gastrin and inhibited with higher doses (> 300 pM). Gastrin stimulated p70 S6 kinase activity for concentrations ranging from 10 pM to 1 nM. Gastrin-stimulated p70 S6 kinase activity and protein synthesis were blocked by rapamycin and wortmannin. Therefore, in ElasCCKB mice acinar cells, the CCKB/gastrin receptor mediates enzyme release and protein synthesis. However, a more efficient coupling of the CCKB/gastrin receptor to protein synthesis than to enzyme secretion was demonstrated. CCKB/gastrin receptor-stimulated protein synthesis likely results from an enhancement of mRNA translation and involves phosphatidyl inositol 3-kinase and p70 S6 kinase.  (+info)

New structural motifs on the chymotrypsin fold and their potential roles in complement factor B. (7/124)

Factor B and C2 are two central enzymes for complement activation. They are multidomain serine proteases and require cofactor binding for full expression of proteolytic activities. We present a 2.1 A crystal structure of the serine protease domain of factor B. It shows a number of structural motifs novel to the chymotrypsin fold, which by sequence homology are probably present in C2 as well. These motifs distribute characteristically on the protein surface. Six loops surround the active site, four of which shape substrate-binding pockets. Three loops next to the oxyanion hole, which typically mediate zymogen activation, are much shorter or absent. Three insertions including the linker to the preceding domain bulge from the side opposite to the active site. The catalytic triad and non-specific substrate-binding site display active conformations, but the oxyanion hole displays a zymogen-like conformation. The bottom of the S1 pocket has a negative charge at residue 226 instead of the typical 189 position. These unique structural features may play different roles in domain-domain interaction, cofactor binding and substrate binding.  (+info)

Formation of intermediate filament protein aggregates with disparate effects in two transgenic mouse models lacking the neurofilament light subunit. (8/124)

Protein aggregates containing intermediate filaments (IFs) are a hallmark of degenerating spinal motor neurons in amyotrophic lateral sclerosis (ALS). Recently, we reported that a deficiency in neurofilament light subunit (NF-L), a phenomenon associated with ALS, promoted the formation of IF inclusions with ensuing motor neuron death in transgenic mice overproducing peripherin, a type III IF protein detected in axonal inclusions of ALS patients. To further assess the role of NF-L in the formation of abnormal IF inclusions, we generated transgenic mice overexpressing human neurofilament heavy subunits (hNF-H) in a context of targeted disruption of the NF-L gene (hH;L-/- mice). The hH;L-/- mice exhibited motor dysfunction, and they developed nonfilamentous protein aggregates containing NF-H and peripherin proteins in the perikarya of spinal motor neurons. However, the perikaryal protein aggregates in the hH;L-/- mice did not provoke motor neuron death, unlike toxic IF inclusions induced by peripherin overexpression in NF-L null mice (Per;L-/- mice). Our results indicate that different types of IF protein aggregates with distinct properties may occur in a context of NF-L deficiency and that an axonal localization of such aggregates may be an important factor of toxicity.  (+info)

A CCK-deficient mouse model was successfully generated by gene targeting in ES cells. The RIA data presented here confirm that this new mutant mouse strain does not produce CCK. CCK-deficient mice are viable and grow at a normal rate. Aging mice (1 yr and older) continued to thrive, with no obviously abnormal pathologies. The body weight, rate of weight gain (Fig. 1 B), and total daily food intake (data not shown) of CCK-deficient mice do not differ from wild-type mice, suggesting that CCK is not essential for maintaining normal energy balance (intake vs. expenditure).. Analysis of pancreatic enzyme content in CCK-deficient mice fed the basal diet revealed an increase in amylase enzyme activity (Table 3). Because chymotrypsinogen content remained unaltered in the mutant, we concluded that the increase in amylase is not due to a general reduction in enzyme secretion but a specific increase in amylase synthesis. Previous studies have demonstrated an inhibitory effect of CCK on amylase synthesis ...

The behavior of monoclonal antibodies at high concentrations is important in downstream processing, drug formulation, and drug delivery. The objective of this study was to evaluate the osmotic pressure of a highly purified monoclonal antibody at concentrations up to 250 g/L over a range of pH and ionic strength, and in the presence of specific excipients, using membrane osmometry. Independent measurements of the second virial coefficient were obtained using self-interaction chromatography, and the net protein charge was evaluated using electrophoretic light scattering. The osmotic pressure at pH 5 and low ionic strength was ,50 kPa for antibody concentrations above 200 g/L. The second virial coefficients determined from the oncotic pressure (after subtracting the Donnan contribution) were in good qualitative agreement with those determined by self-interaction chromatography. The second virial coefficient decreased with increasing ionic strength and increasing pH due to the reduction in ...

Analytical Enzyme Chymotrypsin: Chymotrypsin is produced in the acinar cells of the pancreas as the inactive precursor, chymotrypsinogen.
In enzymes, as with other proteins, function is determined by structure. An enzyme can be a monomeric protein made up of about hundred amino acids or more, or an oligomeric protein consisting of several monomers, different or identical, that act together as a unit. As with any protein, each monomer is actually produced as a long, linear chain of amino acids, which folds in a particular fashion to produce a three-dimensional product. While it is well established that a proteins fold is determined by its primary structure, the factors that go into ensuring that the chain folds correctly and maintains its shape are complex, and still not completely understood, although general principles have been identified. Individual monomers may then combine via non-covalent interactions to form a multimeric protein. The final enzyme molecule might also be modified in various ways to make it active; for instance, chymotrypsin, a digestive protease, is produced in inactive form as chymotrypsinogen in the ...
Patients with rheumatoid arthritis (RA), patients with positive tuberculin (PPD) skin-tests and controls were studied. The lymphocytes from these groups were cultured in serum-free medium to obtain cell-free supernatants. These lymphocyte cultures were pre-incubated with the appropriate antigen or reconstituted after removal of the cells. Supernatants from RA lymphocytes stimulated in vitro by IgG induced an inhibition of the leucocyte migration, as well as the supernatants from tuberculin-sensitized lymphocytes. However, supernatants from non-RA lymphocytes or tuberculin-unsensitized lymphocytes did not show such an inhibition. These MIF-like supernatants have been studied by Sephadex G-100 gel filtration. A MIF activity has been found for PPD and IgG supernatants between the chymotrypsinogen (MW 23,000) and the lysozyme (MW 17,000). This seems to agree with the classical region where MIF can be usually isolated.

TY - JOUR. T1 - The stabilization of proteins by sucrose.. AU - Lee, James. AU - Timasheff, S. N.. PY - 1981/7/25. Y1 - 1981/7/25. N2 - The interactions between proteins and solvent components have been investigated for the sucrose/water system. Thermodynamic and kinetic measurements of the thermal unfolding of alpha-chymotrypsin, chymotrypsinogen, and ribonuclease were performed as a function of sucrose concentration. The alteration in protein-solvent interactions in the presence of sucrose was also studied by density measurements and analyzed by multicomponent thermodynamic theory. Sucrose does not induce a conformational change in three proteins studied, although it does induce a small change in the circular dichroism spectrum of ribonuclease. The enthalpy of thermal unfolding shows little dependence on the concentration of sucrose, while the apparent activation energy of the unfolding process is increased by the addition of sucrose. The results from the protein-solvent interaction study ...

P4-ATPases (flippases) translocate specific phospholipids such as phosphatidylserine from the exoplasmic leaflet of the cell membrane to the cytosolic leaflet, upholding an essential membrane asymmetry. The mechanism of flipping this giant substrate has remained an enigma. We have investigated the importance of amino acid residues in transmembrane segment M4 of mammalian P4-ATPase ATP8A2 by mutagenesis. In the related ion pumps Na+, K+-ATPase and Ca2+-ATPase, M4 moves during the enzyme cycle, carrying along the ion bound to a glutamate. In ATP8A2, the corresponding residue is an isoleucine, which recently was found mutated in patients with cerebellar ataxia, mental retardation, and dysequilibrium syndrome. Our analyses of the lipid substrate concentration dependence of the overall and partial reactions of the enzyme cycle in mutants indicate that, during the transport across the membrane, the phosphatidylserine head group passes near isoleucine-364 (I364) and that I364 is critical to the release of the

Pitzer theory is used to predict the solubility of gypsum, anhydrite and calcite over wide ranges of temperature, pressure, and ionic strength with mixed electrolytes, which usually occurs in deep water oil and gas production. Gypsum solubility was measured from 0 to 40 oC, from 14.7 to 20000 psi, with 0 to 4 mol NaCl/kg H2O. Anhydrite solubility in literature was confirmed and adopted in this study. The equilibrium constants of gypsum and anhydrite were incorporated by temperature and pressure dependent parts from different researches. Along with other virial coefficients, virial coefficients for Ca2+-SO42- interactions were fitted, based on which solubility of gypsum/anhydrite is precisely predicted. They are also applied to accurately predict calcite solubility with mixed electrolytes from 0 to 250 oC (except for 100 oC) up to 21000 psi. The Kassoc for CaSO4(0) derived from b2(CaSO4) in this study matches well with other experimental data at 1 atm 25 oC ...
A review of the basic concept of an analytic dilution assay-one in which relative potency is defined as the ratio of the quantity of effective constituent in unit amount of test to that in the standard-indicates that such an assay is rarely achieved in practice. It is proposed that there are no invalid assays, but only invalid inferences from a set of conditions in which relative potency has been determined and found variable, to new, unknown conditions. Nonparallel log dose-response lines are then interpreted to mean that relative potency varies among other things, with response level, where relative potency is defined as the ratio of doses leading to equal responses. Formulas are given for expressing log relative potency as a function of dose or level of response (formulas 3 and 4) and for making probability statements about it (formulas 9 and 10). The methods are illustrated by reference to a non-parallel log dose-response line assay of two different corticosteroids.. ...

Light scattering measurements have been made on nine polyisobutylene (PIB) fractions in heptane, an intermediate solvent, at 25°C to determine the second virial coefficient A2 and the third virial coefficient A3 as functions of weight-average molecular weight Mw ranging from 2.7×104 to 7.8×106. For six of the fractions, z-average mean-square radii of gyration have also been determined. In the molecular weight range studied, A2 and A3 vary as Mw−0.21 and Mw0.58, respectively, and the factor g defined by A3/A22Mw is about 0.33 almost independent of molecular weight. The data of g and Ψ (the interpenetration function) as functions of the cube of the radius expansion factor αS, combined with previous data in cyclohexane, a good solvent, show that the two-parameter theory breaks down unless αS3 is larger than about 2 for g and about 5 for Ψ. It is concluded from the comparison of these g data with the recent theory of Norisuye et al. that the failure of the two-parameter theory for g at small αS3

The observed minimum in B2 cannot be predicted from standard depletion interaction energy models and is closely associated with proximity to the lower critical solution temperature of the polymer solution. The location, depth, and molecular weight dependence of the minima are captured by the thermal polymer reference interaction site model for depletion interactions, where the polymer mesh size is a function of temperature..

A six-dimensional potential energy hypersurface (PES) for two interacting rigid ethylene oxide (C{sub 2}H{sub 4}O) molecules was determined from high-level quantum-chemical ab initio calculations. The counterpoise-corrected supermolecular approach at the MP2 and CCSD(T) levels of theory was utilized to determine interaction energies for 10178 configurations of two molecules. An analytical site-site potential function with 19 sites per ethylene oxide molecule was fitted to the interaction energies and fine tuned to agree with data for the second acoustic virial coefficient from accurate speed of sound measurements. The PES was validated by computing the second virial coefficient, shear viscosity, and thermal conductivity. The values of these properties are substantiated by the best experimental data as they tend to fall within the uncertainty intervals and also obey the experimental temperature functions, except for viscosity, where experimental data are insufficient. Due to the lack of reliable ...

The BANK BOARD Letter Edited exclusively for directors of financial institutions and their holding companies november 2015 INTEREST RATE RISK MANAGEMENT: A CLOSER LOOK By KEnnEth Bishop M anaging interest rate risk is one of the most important responsibilities for bank manage-ment and the board of directors. With inter-est rates expected to rise after several years of historic lows, have you taken a close look at your process for managing this risk? An effective process can better prepare the bank to develop prudent strategies in a changing environ-ment. When reflecting on your process, the follow-ing are some simple questions to ask yourself. of measurements that can be applied to monitor in-terest rate risk, which the board should understand and tailor to the banks size and complexity. This can include parallel and non-parallel shocks; gradual shifts; and dynamic or static conditions, along with determining the magnitude of rate increases and decreases over varying time horizons. are key ...
A bone anchor includes an anchor body configured to be retained within bone. The anchor body includes a restrictor defining an opening having a first portion for permitting passage of a member therethrough, and a second portion restricting passage of the member therethrough. The member is movable between the first and second portions in a direction non-parallel to a direction of passage of the member through the opening. The restrictor includes an edge lining the opening oriented obliquely to a direction of passage of the member through the opening. The anchor body includes one or more resilient members with sharp, proximal edges for penetrating bone tissue.

This 11 x 14 (24.9 by 35.6 cm) photograph shows recipients of the Type II Sabin oral polio vaccine immunization program in Youngstown in 1962. In this image parents and children can be seen lining up to get vaccinations at one of the 18 polio vaccinations centers in Mahoning County. The immunization program was sponsored by the Mahoning County Medical Society and was endorsed by the American Medial Association. The vaccine developed by Albert B. Sabin, which uses a weakened form of the disease-causing virus, was easier to administer than the injection developed by Jonas Salk, in which the virus is inactivated or killed. Colorless and tasteless, the Sabin vaccine could be dispensed by dropper, mixed with distilled water, or put into a sugar cube. Two phases of mass immunizations using the Sabin vaccine occurred in late 1961 and early 1962 in Youngstown, one on November 30 and December 2, 1961 and the other on February 15 and 17, 1962. During each phase approximately 130,000 Mahoning County ...
