description: The origin of the highest-energy cosmic rays remains elusive. The decay of a superheavy particle (X) into an ultra-energetic neutrino which scatters from a relic (anti-)neutrino at the Z-resonance has attractive features. Given the necessary X mass of $10^{14\sim15}$ GeV, the required lifetime, $10^{15\sim16}$ y, renders model-building a serious challenge but three logical possibilities are considered: (i) X is a Higgs scalar in SU(15) belonging to high-rank representation, leading to {\it power}-enhanced lifetime; (ii) a global X quantum number has {\it exponentially}-suppressed symmetry-breaking by instantons; and (iii) with additional space dimension(s) localisation of X within the real-world brane leads to {\it gaussian} decay suppression, the most efficient of the suppression mechanisms considered.

description: Drug-resistant tumor cells actively extrude a variety of chemotherapeutic agents by the action of the multi-drug resistance (MDR1) gene product, the plasma membrane P-glycoprotein. In this report we show that the expression of the human MDR1 gene in cultured Sf9 insect cells via a baculovirus vector generates a high activity vanadate-sensitive membrane ATPase. This ATPase is markedly stimulated by drugs known to interact with the P-glycoprotein, such as vinblastine and verapamil, and the ability of the various drugs to stimulate the ATPase corresponds to their previously observed affinity for this transporter. The drug-stimulated ATPase is not present in uninfected or mock-infected Sf9 cells, and its appearance correlates with the appearance of the MDR1 gene product detected with a monoclonal anti-MDR protein antibody and by labeling with 8-azido-ATP. The drug-induced ATPase requires magnesium ions, does not utilize ADP or AMP as substrates, exhibits a half-maximal activation at about 0.5 mM MgATP, and its maximal activity (about 3-5 mumol/mg MDR protein/min) approaches that of the well characterized ion transport ATPases. These results provide the first direct demonstration of a high capacity drug-stimulated ATPase activity of the human multidrug resistance protein and offer a new and simple assay for the investigation of functional interactions of various drugs with this clinically important enzyme.

description: We study observational consequences of the model for dark energy proposed in [1] (Aoki et al., Phys.Rev. D97 (2018) no.4, 043517). We assume our universe has been created by bubble nucleation, and consider quantum fluctuations of an ultralight scalar field. Residual effects of fluctuations generated in an ancestor vacuum (de Sitter space in which the bubble was formed) is interpreted as dark energy. Its equation of state parameter w(z) has a characteristic form, approaching -1 in the future, but -1/3 in the past. A novel feature of our model is that dark energy effectively increases the magnitude of the negative spatial curvature in the evolution of the Hubble parameter, though it does not alter the definition of the angular diameter distance. We perform Fisher analysis and forecast the constraints for our model from future galaxy surveys by Square Kilometre Array and Euclid. Due to degeneracy between dark energy and the spatial curvature, galaxy surveys alone can determine these parameters only for optimistic choices of their values, but combination with other independent observations, such as CMB, will greatly improve the chance of determining them.

title: Investigation of the mechanisms underlying the effect of oleic acid and docosahexaenoic acid on DNA methylation in jurkat cells
Creators: name: Perez Mojica, Jose Eduardo
Publisher: name: University of Southampton
Year: 2019

description: There is evidence that olive oil, rich in oleic acid (OA), and fish oil, rich in docosa-hexaenoic acid (DHA), can modify the DNA methylation in human blood cellsinvivo. However, the mechanisms underlying such effect are not well understood. Toaddress this, a model to study DNA methylation changes was developed using theinvitrotreatment of Jurkat cells with OA or DHA. Analysis showed that 15Î¼M OA orDHA treatment for eight days altered the DNA methylation of 563 or 1596 CpG sites(294 or 508 increased), respectively, using the Infinium MethylationEPIC BeadChip.Only 78 CpG sites were altered in common by both treatments. Further characte-risation of 5 candidate CpG sites showed that DNA methylation changes were justsignificant after the 3rdday of DHA treatment which suggested and indirect mecha-nism. Pathway analysis of genes with at least one CpG site with altered DNA methy-lation by OA or DHA treatment (348 or 935, respectively) showed an enrichment ofgenes under the control of peroxisome proliferator-activated receptor alpha (PPARÎ±)in DHA-treated cells only. PPARÎ±has been reported to participate in the global hy-permethylation of THP1 monocytes induced by arachidonic acid treatment. How-ever, treatment of Jurkat cells with PPARÎ±agonist GW7647 or PPARÎ±antagonistGW6471 showed no difference in the DNA methylation of 5 candidate CpG sites anal-ysed here by pyrosequencing. Therefore, other factors related to DNA methylationsuch as chromatin modification of histones and DNA motifs were investigated. Re-sults showed that H3K4me3 was decreased in 5 candidate regions that changed DNAmethylation status. Motif analysis indicated that sequences in the proximity of CpGsites that changed methylation were enriched in response elements including thosefor transcription factor SP1 and SP3. To further characterise the participation oftranscription factors, transcriptome changes by OA or DHA were assessed using theHumanHT-12 v4 Expression BeadChip. Analysis showed that DHA, but not OA treat-ment, downregulatedSP3mRNA and altered the activity of different transcriptionfactors and enzymes. Together, results showed in this thesis suggest that DNA methy-lation changes by OA or DHA showed specificity, took more than three days to be es-tablished and may be associated with decrease H3K4me3 and the activity of differenttranscription factors and enzymes.

description: The short range repulsion between nucleons is treated by a unitary correlation operator which shifts the nucleons away from each other whenever their uncorrelated positions are within the replusive core. By formulating the correlation as a transformation of the relative distance between particle pairs, general analytic expressions for the correlated wave functions and correlated operators are given. The decomposition of correlated operators into irreducible n-body operators is discussed. The one- and two-body-irreducible parts are worked out explicitly and the contribution of three-body correlations is estimated to check convergence. Ground state energies of nuclei up to mass number A=48 are calculated with a spin-isospin-dependent potential and single Slater determinants as uncorrelated states. They show that the deduced energy- and mass-number-independent correlated two-body Hamiltonian reproduces all "exact" many-body calculations surprisingly well.

description: The Saccharomyces cerevisiae YDJ1 protein (YDJ1p) contains a C-terminal "CaaX box" motif common to proteins that are modified by prenylation. In the present study we show that YDJ1p is a specific substrate for both yeast and mammalian protein farnesyltransferase enzymes in vitro. A mutant form of YDJ1p, in which the conserved cysteine of the CaaX box is mutated to a serine (ydj1-S406p), cannot be farnesylated in vitro. After expression in S. cerevisiae, ydj1-S406p displays a reduced electrophoretic mobility and an increased cytosolic localization in subcellular fractionation experiments when compared to wild type YDJ1p. Expression of ydj1-S406 in cells lacking YDJ1 results in a temperature-sensitive growth phenotype in S. cerevisiae. These data indicate that farnesylation of YDJ1p is required for its function at elevated temperatures

description: The isotropic harmonic oscillator in dimension 3 separates in several different coordinate systems. Separating in a particular coordinate system defines a system of three commuting operators, one of which is the Hamiltonian. We show that the joint spectrum of the Hamilton operator, the $z$ component of the angular momentum, and a quartic integral obtained from separation in prolate spheroidal coordinates has quantum monodromy for sufficiently large energies. This means that one cannot globally assign quantum numbers to the joint spectrum. The effect can be classically explained by showing that the corresponding Liouville integrable system has a non-degenerate focus-focus point, and hence Hamiltonian monodromy.

description: We investigate the spin 1/2 Heisenberg star introduced in J. Richter and A. Voigt, J. Phys. A: Math. Gen. {\bf 27}, 1139 (1994). The model is defined by $H=J_1 \sum_{i=1}^{N}{{\bf s}_0{\bf s}_i} + J_2 H_{R}\{{\bf s}_i\}$ ; $J_1,J_2 \ge 0$ , $i=1,...,N$. In extension to the Ref. we consider a more general $H_{R}\{{\bf s}_i\}$ describing the properties of the spins surrounding the central spin ${\bf s}_0$. The Heisenberg star may be considered as an essential structure element of a lattice with frustration (namely a spin embedded in a magnetic matrix $H_R$) or, alternatively, as a magnetic system $ H_R $ with a perturbation by an extra spin. We present some general features of the eigenvalues, the eigenfunctions as well as the spin correlation $\langle {\bf s}_0{\bf s}_i \rangle$ of the model. For $H_R$ being a linear chain, a square lattice or a Lieb-Mattis type system we present the ground state properties of the model in dependence on the frustration parameter $α=J_2/J_1$. Furthermore the thermodynamic properties are calculated for $H_R$ being a Lieb--Mattis antiferromagnet.

Fibrinogen binding to purified platelet glycoprotein IIb-IIIa (integrin alpha IIb beta 3) is modulated by lipids.

description: Soluble fibrinogen binding to the glycoprotein IIb-IIIa complex (integrin alpha IIb beta 3) requires platelet activation. The intracellular mediator(s) that convert glycoprotein IIb-IIIa into an active fibrinogen receptor have not been identified. Because the lipid composition of the platelet plasma membrane undergoes changes during activation, we investigated the effects of lipids on the fibrinogen binding properties of purified glycoprotein IIb-IIIa. Anion exchange chromatography of lipids extracted from platelets exposed to thrombin or other platelet agonists resolved an activity that increased fibrinogen binding to glycoprotein IIb-IIIa. A monoester phosphate was important for activity, and phosphatidic acid coeluted with the peak of activity. Purified phosphatidic acid dose-dependently promoted a specific interaction between glycoprotein IIb-IIIa and fibrinogen which possessed many but not all of the properties of fibrinogen binding to activated platelets. Phosphatidic acid appeared to increase the proportion of fibrinogen binding-competent glycoprotein IIb-IIIa complexes without altering their affinity for fibrinogen. The effects of phosphatidic acid were a result of specific structural properties of the lipid and were not mimicked by other phospholipids. Lysophosphatidic acid, however, was a potent inducer of fibrinogen binding to glycoprotein IIb-IIIa. These results demonstrate that specific lipids can affect fibrinogen binding to purified glycoprotein IIb-IIIa and suggest that the lipid environment has the potential to influence fibrinogen binding to its receptor.
Neutron lifetime puzzle and neutron -- mirror neutron oscillation

description: The discrepancy between the neutron lifetimes measured in the beam and trap experiments can be explained via the neutron $n$ conversion into mirror neutron $n'$, its dark partner from parallel mirror sector, provided that $n$ and $n'$ have a tiny mass splitting order $10^{-7}$ eV. In large magnetic fields used in beam experiments $n-n'$ transition is resonantly enhanced and can transform of about a per cent fraction of neutrons into mirror neutrons which decay in invisible mode. Thus less protons will be produced and the measured value $τ_{\rm beam}$ appears larger than $β$-decay time $τ_β = τ_{\rm trap}$. Some phenomenological and astrophysical consequences of this scenario are also briefly discussed.

The model is fitted to the data on dsigma/dt, B and elastic sigma for Q^2=0 and beyond the threshold region. The elastic cross sections for both phi and J/psi photoproduction show a moderate increase within the HERA energy region. The flattening of the slope B(s) (little or no shrinkage) for J/psi is not correlated with the slope of the Pomeron trajectory. Estimates for Upsilon photoproduction at HERA are given.

Heparin binding to protein C inhibitor
Creators: name: PRATT, C.
name: CHURCH, F.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: Protein C inhibitor is a plasma protein whose ability to inhibit activated protein C, thrombin, and other enzymes is stimulated by heparin. These studies were undertaken to further understand how heparin binds to protein C inhibitor and how it accelerates proteinase inhibition. The region of protein C inhibitor from residues 264-283 was identified as the heparin-binding site. This differs from the putative heparin-binding site in the related proteins antithrombin and heparin cofactor. The glycosaminoglycan specificity of protein C inhibitor was relatively broad, including heparin and heparan sulfate, but not dermatan sulfate. Non-sulfated and non-carboxylated polyanions also enhanced proteinase inhibition by protein C inhibitor. Heparin accelerated inhibition of alpha-thrombin, gamma T-thrombin, activated protein C, factor Xa, urokinase, and chymotrypsin, but not plasma kallikrein. The ability of glycosaminoglycans to accelerate proteinase inhibition appeared to depend on the formation of a ternary complex of inhibitor, proteinase, and glycosaminoglycan. The optimum heparin concentration for maximal rate stimulation varied from 10 to 100 micrograms/ml and was related to the apparent affinity of the proteinase for heparin. There was no obvious relationship between heparin affinity and maximum inhibition rate or degree of rate enhancement. The affinity of the resultant protein C inhibitor-proteinase complex was also not related to inhibition rate enhancement, and the results showed that decreased heparin affinity of the complex is not an important part of the catalytic mechanism of heparin. The importance of protein C inhibitor as a regulator of the protein C system may depend on the relatively large increase in heparin-enhanced inhibition rate for activated protein C compared to other proteinases.
cold dust and stellar emissions of dust rich galaxies at z=2 observed with ALMA: a challenge for SED fitting techniques
Creators: name: BUAT Véronique
Publisher: name: Zenodo
Year: 2019

description: Over the past few years the Atacama Large Millimeter Array (ALMA) has detected dust-rich galaxies whose cold dust emission is spatially disconnected from the ultraviolet (UV) rest-frame emission. This represents a challenge for modeling their spectral energy distributions (SED) with codes based on an energy budget between the stellar and dust components. This could potentially weaken the solidity of the physical parameters measured with these modeling tools.
 We select 17 sources at z=2 in the Hubble Ultra-Deep Field (HUDF) and in the GOODS-South field detected with ALMA and {\sl Herschel} and for which UV to near-infrared rest-frame ancillary data are available. We fit the data with CIGALE exploring different configurations for dust attenuation and star formation histories, considering either the full dataset or one that is reduced to the stellar and dust emission. The fit of the stellar continuum alone with the starburst attenuation law can only reproduce up to 50% of the total dust luminosity observed by Herschel and ALMA. This deficit is found to be marginally consistent with similar quantities estimated in the COSMOS field and is found to increase with the specific star formation rate. The combined stellar and dust SEDs are well fitted when different attenuation laws are introduced. Shallow attenuation curves are needed for the galaxies whose cold dust distribution is very compact compared to starlight. The stellar mass estimates are affected by the choice of the attenuation law. The star formation rates are robustly estimated as long as dust luminosities are available. The large majority of the galaxies are above the average main sequence of star forming galaxies and one source is a strong starburst.
Identification of a receptor binding site in the carboxyl terminus of human interleukin-6
Creators: name: The University of North Carolina at Chapel Hill University Libraries
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1992

description: To identify a receptor binding site of human interleukin-6 (IL-6), we created a library of IL-6 variants with single amino acid substitutions in the last 15 residues (171-185) in the COOH terminus of IL-6. Twenty-seven IL-6 variants were tested for biological activity on a human hepatoma and a mouse hybridoma cell line. Most variants were additionally tested in a receptor binding assay using a human myeloma cell line. Several single amino acid substitutions in the COOH terminus of IL-6 were found to decrease biological activity significantly. This is especially seen in variants with amino acid substitutions that alter the postulated amphipathical alpha-helix structure between residues 178 and 183. The two highly conserved Arg residues at positions 180 and 183 seem to play a very important role in biological activity. The loss of biological activity in all inactive variants is completely paralleled by a decrease of IL-6 receptor binding, as determined by competition binding experiments. One mutant (Leu171) displayed a higher activity on human cells and a higher binding affinity to the receptor and can be considered an IL-6 agonist. It is concluded that the amphipathical alpha-helix structure in the COOH terminus of IL-6 is critical for ligand receptor interaction. Furthermore, the region between residues Ser178 and Arg183 (Ser-Leu-Arg-Ala-X-Arg) is identified as a receptor binding site in the COOH terminus of human IL-6.

description: Starting from an ideal crystalline state, we numerically study a nonequilibrium dynamical order- disorder transition promoted by the application of a periodic shearing protocol at low temperatures in model systems in two and three dimensions. We observe a continuous (2D) and discontinuous (3D) dynamical transition from an ordered to a disordered steady state. Through the analysis of large-scale simulations, we show that the amorphization mechanism around the discontinuous transition is reminiscent of spinodal decomposition.

Monsieur,

Je ne pouvais m’adresser à une personne plus instruite que vous pour ce qui regardait M. Arlier. Les détails où vous êtes entré et les éclaircissements que vous m’avez donné m’ontmis pleinement en état de le connaître. Je les ai communiqués à M. Bonet, chantre de l’église cathédrale de Montpellier, pour qui je vous les demandais, qui en a été extrêmement satisfait et qui m’a chargé de vous faire ses remerciements. C’est lui qui possède le manuscrit des lettres de cet illustre et qui se propose de le faire imprimer. Il l’apporta à Aubais dans le mois de novembre dernier lorsque j’y étais; et M. le marquis d’Aubais en prit une notice, de même qu’une copie de votre lettre qui lui parut fort intéressante. Vous soupçonnez très bien que cette famille pouvait être originaire de Calvisson. Il y a encore une métairie qui doit avoir appartenu à son frère, dont il parle dans ses lettres, et c’est le Lauretum dont il est fait mention dans plusieurs endroits. Dans les ouvrages manuscrits de Rulman qui sont à la Bibliothèque d’Aubais, il est parlé de cet Arlier en ces termes:
«Harlier, homme de doctrine et de condition, officier du roi au Sénéchal, employé d’ordinaire aux affaires du public, lequel fut employé en Piémont de la part de S.Mé. pour négocier les intérêts de la France auprès de S. Altesse, fit un voyage exprès en Cour, après le passage de ce grand roi des armes et des bonnes lettres, lequel étant le/ [p. 491] nourricier et le nourrisson des Muses lui fit expédier favorablement des patentes sur ce sujet et lui commanda de lui rendre bon compte des moyens qu’il préjugerait les plus propres et les plus prompts pour la restauration des anciens monuments de la ville.»
Si à l’avenir vous trouvez quelque nouvel éclaircissement servant à la vie de notre concitoyen, vous me ferez plaisir de me le communiquer. Le long séjour que j’ai fait à Aubais, où j’attendais M. Bonet pour conférer avec lui, et bien d’autres petites affaires m’ont empêché de vous faire plus tôt mes remerciements que vous prie de recevoir.
Recevez aussi, je vous prie, les vœux sincères que je fais pour vous au commencement de cette nouvelle année, que vous souhaite aussi heureuse que vous la pouvez désirer.
J’ai l’honneur d’être, avec un attachement sincère et respectueux,
Monsieur,

range Uruguay, and widespread through Argentina, from Jujuy and Santa Fe in the north to Rio Negro in the south.
biology Bruch (1916) describes bergi as an abundant, widespread species in Argentina. It builds conspicuous soil nests, each with a single entrance hole 2-3 cm in diameter, often surrounded by a crater or partially by a semicircle of excavated soil as much as 25 cm in diameter. A single gallery descends to a succession of 5 to 10 roughly ellipsoidal chambers, each spaced about equally apart, and reaching a depth of 40-60 cm. The colonies are aggressive, with a high proportion of majors, and exclusively insectivorous. They readily attack other colonies of their own and other ant species.

description: The late-time entropy production by the massive particle decay induces the various cosmological effects in the early epoch and modify the standard scenario. We investigate the thermalization process of the neutrinos after the entropy production by solving the Boltzmann equations numerically. We find that if the large entropy are produced at t $\sim$ 1 sec, the neutrinos are not thermalized very well and do not have the perfect Fermi-Dirac distribution. Then the freeze-out value of the neutron to proton ratio is altered considerably and the produced light elements, especially He4, are drastically changed. Comparing with the observational light element abundances, we find that $T_R$ < 0.7 MeV is excluded at 95 % C.L. We also study the case in which the massive particle has a decay mode into hadrons. Then we find that $T_R$ should be a little higher, i.e. $T_R$ > 2.5 MeV - 4 MeV, for the hadronic branching ratio $B_h = 10^{-2} - 1$. Possible influence of late-time entropy production on the large scale structure formation and temperature anisotropies of cosmic microwave background is studied. It is expected that the future satellite experiments (MAP and PLANCK) to measure anisotropies of cosmic microwave background radiation temperature can detect the vestige of the late-time entropy production as a modification of the effective number of the neutrino species $N_ν^{\rm eff}$.

description: Photolyases contain two chromophores, flavin plus either methenyltetrahydrofolate (MTHF) or 8-OH-5-deazaflavin (HDF). Amino acid sequence comparison reveals that all photolyases sequenced to date have extensive sequence homology in the carboxyl-terminal half; in the amino-terminal region the folate and deazaflavin class enzymes are more homologous to other members of the same class. This modular arrangement of sequence homologies suggests that the amino-terminal half of photolyase is involved in MTHF or HDF binding whereas the carboxyl-terminal half carries the flavin binding site. In this study we attempted to identify such structural domains of yeast photolyase by partial proteolysis and gene fusion techniques. Partial digestion with chymotrypsin yielded an amino-terminal 34-kDa fragment containing tightly bound MTHF and a carboxyl-terminal 20-kDa polypeptide which lacked chromophore or DNA binding activity. However, a fusion protein carrying the carboxyl-terminal 275 amino acids of yeast photolyase bound specifically to FAD but not to MTHF or DNA. We conclude that the amino-terminal half of yeast photolyase constitutes the folate binding domain and that the carboxyl-terminal half carries the flavin binding site.

description: Superconductivity in FeSe has recently attracted a great deal of attention because it emerges out of an electronic nematic state of elusive character. Here we study both the electronic normal state and the superconducting gap structure using heat-capacity measurements on high-quality single crystals. The specific-heat curve, from 0.4 K to Tc = 9.1 K, is found to be consistent with a recent gap determination using Bogoliubov quasiparticle interference [P. O. Sprau et al., Science 357, 75 (2017)], however only if nodes are introduced on either the electron or the hole Fermi-surface sheets. Our analysis, which is consistent with quantum-oscillation measurements, relies on the presence of only two bands, and thus the fate of the theoretically predicted second electron pocket remains mysterious.

description: We present solutions of the coupled, non-relativistic $^3S_1$-$^3D_1$ gap equations for neutron-proton pairing in symmetric nuclear matter, and estimate relativistic effects by solving the same gap equations modified according to minimal relativity and using single-particle energies from a Dirac-Brueckner-Hartree-Fock calculation. As a main result we find that relativistic effects decrease the value of the gap at the saturation density $k_F=1.36 fm^{-1}$ considerably, in conformity with the lack of evidence for strong neutron-proton pairing in finite nuclei.

description: Innovation in the world of today is mainly driven by software. Companies need to continuously rejuvenate their product portfolios with new features to stay ahead of their competitors. For example, recent trends explore the application of blockchains to domains other than finance. This paper analyzes the state-of-the-art for safety-critical systems as found in modern vehicles like self-driving cars, smart energy systems, and home automation focusing on specific challenges where key ideas behind blockchains might be applicable. Next, potential benefits unlocked by applying such ideas are presented and discussed for the respective usage scenario. Finally, a research agenda is outlined to summarize remaining challenges for successfully applying blockchains to safety-critical cyber-physical systems.

description: The phenomenological implications of the M-theory limit in which supersymmetry is broken by the F-terms of five-brane moduli is investigated. In particular we calculate the supersymmetric spectrum subject to constraints of correct electroweak symmetry breaking. We find interesting differences especially in the squark sector compared with $M$-theory scenarios with standard embedding and weakly-coupled Calabi-Yau compactifications in the large $T$-limit.

Identification of the forms of insulin-like growth factor-binding proteins produced by human fibroblasts and the mechanisms that regulate their secretion

description: Human fibroblasts secrete insulin-like growth factor-binding proteins (IGFBPs) that can modify insulin-like growth factor (IGF) I action. We have determined the molecular identities of three forms of IGFBPs that are secreted by human fibroblasts in vitro. Ligand blot analysis of fibroblast conditioned media revealed that the M(r) 43,000 and 39,000 forms were the most abundant, but that M(r) 31,000 and 24,000 forms were also present. An antiserum that was specific for IGFBP-5 reacted with the M(r) 31,000 form, and an IGFBP-4-specific antiserum recognized only the M(r) 24,000 form. The M(r) 39,000 and 43,000 forms were detected by IGFBP-3 antiserum. Further proof that fibroblasts synthesized these forms of IGFBPs was obtained by Northern blotting. A cDNA probe for IGFBP-3 hybridized with a 2.4-kilobase (kb) transcript, whereas a cDNA probe for IGFBP-5 recognized a single 6.0-kb transcript, and an IGFBP-4 cDNA probe recognized 2.2- and 2.0-kb transcripts. IGF-I and -II caused a minimal (less than 43%) increase in IGFBP-5 mRNA abundance and had no effect on IGFBP-4 mRNA abundance. IGF-I and -II (100 ng/ml) stimulated 6-8-fold increases in IGFBP-5 levels, whereas IGFBP-4 was inhibited. Insulin failed to elicit any change in IGFBP-5, suggesting that binding of the IGFs to IGFBPs was required to detect the increase. Immunoblotting for IGFBP-5 revealed an M(r) 23,000 (non-IGF-I-binding) fragment. To determine if the IGFs were influencing proteolytic degradation of IGFBP-5, pure IGFBP-5 was added to fibroblast cultures and incubated for 4 h at 37 degrees C. The amount of fragment formation was attenuated by the presence of IGF-I and -II, but not insulin, suggesting that this is a mechanism by which the IGFs act to modulate IGFBP-5 concentration. In contrast to the IGFs, forskolin, which increased IGFBP-4 and -5 mRNA abundance and secretion, had no effect on fragment formation. The results show that human fibroblasts synthesize and secrete IGFBP-3, -4, and -5 and that changes in intracellular cAMP regulate synthesis, whereas the IGFs regulate IGFBP-4 and -5 levels by post-transcriptional mechanisms.
