A Novel Mammalian Retromer Component, Vps26B

The mammalian retromer protein complex, which consists of three proteins - Vps26, Vps29, and Vps35 - in association with members of the sorting nexin family of proteins, has been implicated in the trafficking of receptors and their ligands within the endosomal/lysosomal system of mammalian cells. A bioinformatic analysis of the mouse genome identified an additional transcribed paralog of the Vps26 retromer protein, which we termed Vps26B. No paralogs were identified for Vps29 and Vps35. Phylogenetic studies indicate that the two paralogs of Vps26 become evident after the evolution of the chordates. We propose that the chordate Vps26-like gene published previously be renamed Vps26A to differentiate it from Vps26B. As for Vps26A, biochemical characterization of Vps26B established that this novel 336 amino acid residue protein is a peripheral membrane protein. Vps26B co-precipitated with Vps35 from transfected cells and the direct interaction between these two proteins was confirmed by yeast 2-hybrid analysis, thereby establishing Vps26B as a subunit of the retromer complex. Within HeLa cells, Vps26B was found in the cytoplasm with low levels at the plasma membrane, while Vps26A was predominantly associated with endosomal membranes. Within A549 cells, both Vps26A and Vps26B co-localized with actin-rich lamellipodia at the cell surface. These structures also co-localized with Vps35. Total internal reflection fluorescence microscopy confirmed the association of Vps26B with the plasma membrane in a stable HEK293 cell line expressing cyan fluorescent protein (CFP)-Vps26B. Based on these observations, we propose that the mammalian retromer complex is located at both endosomes and the plasma membrane in some cell types.

Development of a quasi-chemical viscosity model for fully liquid slags in the Al2O3-CaO-'FeO'-MgO-SiO2 system. Part 2. A review of the experimental data and the model predictions for the Al2O3-CaO-MgO, CaO-MgO-SiO2 and Al2O3-MgO-SiO2 systems

A structurally-based quasi-chemical viscosity model has been developed for the Al2O3 CaO-'FeO'-MgO-SiO2 system. The model links the slag viscosity to the internal structure of melts through the concentrations of various anion/cation Si0.5O, Me2/nn+O and Me1/nn+Si0.25O viscous flow structural units. The concentrations of structural units are derived from the quasi-chemical thermodynamic model. The focus of the work described in the present paper is the analysis of experimental data and the viscosity models for fully liquid slags in the Al2O3-CaO-MgO, Al2O3 MgO-SiO2 and CaO-MgO-SiO2 systems.

Regulation of albumin endocytosis by PSD95/Dlg/ZO-1 (PDZ) scaffolds - Interaction of Na+-H+ exchange regulatory factor-2 with ClC-5

The constitutive reuptake of albumin from the glomerular filtrate by receptor-mediated endocytosis is a key function of the renal proximal tubules. Both the Cl- channel ClC-5 and the Na+-H+ exchanger isoform 3 are critical components of the macromolecular endocytic complex that is required for albumin uptake, and therefore the cell-surface levels of these proteins may limit albumin endocytosis. This study was undertaken to investigate the potential roles of the epithelial PDZ scaffolds, Na+-H+ exchange regulatory factors, NHERF1 and NHERF2, in albumin uptake by opossum kidney ( OK) cells. We found that ClC-5 co-immunoprecipitates with NHERF2 but not NHERF1 from OK cell lysate. Experiments using fusion proteins demonstrated that this was a direct interaction between an internal binding site in the C terminus of ClC-5 and the PDZ2 module of NHERF2. In OK cells, NHERF2 is restricted to the intravillar region while NHERF1 is located in the microvilli. Silencing NHERF2 reduced both cell-surface levels of ClC-5 and albumin uptake. Conversely, silencing NHERF1 increased cell-surface levels of ClC-5 and albumin uptake, presumably by increasing the mobility of NHE3 in the membrane and its availability to the albumin uptake complex. Surface biotinylation experiments revealed that both NHERF1 and NHERF2 were associated with the plasma membrane and that NHERF2 was recruited to the membrane in the presence of albumin. The importance of the interaction between NHERF2 and the cytoskeleton was demonstrated by a significant reduction in albumin uptake in cells overexpressing an ezrin binding-deficient mutant of NHERF2. Thus NHERF1 and NHERF2 differentially regulate albumin uptake by mechanisms that ultimately alter the cell-surface levels of ClC-5.

Vascular remodelling in the internal mammary artery graft and association with elevated endothelin-1 expression

Introduction: The vasoconstricting peptide Endothelin-1 (ET-1) has been associated with atherosclerotic cardiovascular disease, AAA, hypertension and hypercholesterolemia. It is known to stimulate quiescent vascular smooth muscle cells (VSMC) into the growth cycle and has been linked to intimal thickening following endothelial injury and is associated with vessel wall remodelling in salt-sensitive hypertension models. Enhanced ET-1 expression has been reported in the internal mammary artery (IMA) and was markedly higher in patients undergoing cardiac bypass surgery who were diabetic and /or hypercholesterolemic. Aims: To firstly review the histopathology of the IMA and secondly, determine the relationship between ET-1 expression in this vessel and mitogenic activity in the medial VSMC. Methods: Vessel tissue collected at the time of CABG surgery was formalin-fixed and paraffin-embedded for histological investigation. Cross sections of the left distal IMAwere stained with Alcian Blue/Verhoeff’s van Gieson to assess medial degeneration and identify the elastic lamellae and picrosirius red to determine the collagen content (specifically type I and type III). Immunohistochemistry staining was used to assess VSMC growth (PCNA label), tissue ET-1 expression, VSMC (SMCa-actin) area and macrophage/monocyte (anti-CD68) infiltration. Quantitative analysis was performed to measure the VSMC area in relation to ET-1 staining. Results: Fifty-five IMA specimens from the CABG patients (10F; 45M; mean age 65 years) were collected for this study. Fourteen donor IMAspecimens were used as controls (7F; 7M; mean age 45 years). Significant medial hypertrophy, VSMC disorganisation and elastic lamellae destruction was detected in the CABG IMA. The amount of Alcian blue staining in the CABG IMA was almost double that of the control (31.85+/14.52% Vs 17.10+/9.96%, P= .0006). Total collagen and type I collagen content was significantly increased compared with controls (65.8+/18.3% Vs 33.7 + / 13.7%, P= .07), (14.2 + /10.0% Vs 4.8 + /2.8%, P= .01), respectively. Tissue ET-1 and PCNA labelling were also significantly elevated the CABG IMA specimens relative to the controls (69.99 + /18.74%Vs 23.33 + /20.53%, P= .0001, and 37.29 + /12.88% Vs 11.06 + /8.18, P= .0001), respectively. There was mild presence of macrophages and monocytes in both CABG and control tissue. Conclusions: The IMA from CABG patients has elevated levels of type I collagen in the extracellular matrix indicative of fibrosis and was coupled with deleterious structural remodelling. Abnormally high levels of ET-1 were measured in the medial SMC layer and was associated with VSMC growth but not related to any chronic inflammatory response within the vessel wall.

MALAQUIAS, MENSAGEIRO DA JUSTIÇA:UM ESTUDO A PARTIR DO QUARTO ORÁCULO (2,17-3,5)

O livro de Malaquias apresenta oráculos que conservam informações relevantes do período pós exílico sob o domínio da Pérsia e, especialmente, os problemas religiosos focalizando a displicência dos sacerdotes no cumprimento de suas funções e os problemas sociais apontando para um amplo movimento de opressão externa e interna. Esta pesquisa buscou verificar, no primeiro capítulo, como a mensagem de Malaquias através de sua forma e conteúdos visava aplacar as insatisfações internas dos grupos que habitavam o território de Judá. Neste capítulo, foram abordadas as discussões histórico-literárias sobre data, autoria, destinatários, forma do anúncio. Ainda procurou-se realizar levantamentos históricos verificando o sistema e as estruturas de opressão dos persas no território de Judá e também as faces da reorganização da sociedade de Judá. O segundo capítulo enfatizou, mais propriamente, o trabalho exegético no quarto oráculo (2,17-3,5). Neste pode-se verificar uma síntese dos temas centrais da mensagem de Malaquias: O juízo divino que viria pela negligência religiosa e que exigia compromissos com a justiça prática na vida do povo. A partir das discussões exegéticas buscou-se verificar como o profeta apresentou ao povo e aos sacerdotes quais seriam os agentes e as ações transformadoras que Javé promoveria para restaurar a justiça e o culto purificado. O terceiro capítulo apresenta um tema recorrente nos oráculos do livro de Malaquias: a justiça. Para isso, foram analisadas três perícopes que tratam o tema da justiça enfocadamente, as influências do sistema judicial persa na prática da justiça cotidiana em Judá e a realidade de opressão nos sistema de parentesco entre as famílias (clãs) que habitavam o território de Judá - (2,10-16; 2,17-3,5 e 3,13-21). A pesquisa de Malaquias aponta para um profeta engajado política e socialmente. O Mensageiro manteve os ideais proféticos e desejou reacender os valores da aliança entre o povo e fortalecer a confiança na ação de Javé que restauraria a justiça na prática cotidiana.(AU)

Internal versus external R&D:a study of R&D choice with sample selection

This paper extends previous analyses of the choice between internal and external R&D to consider the costs of internal R&D. The Heckman two-stage estimator is used to estimate the determinants of internal R&D unit cost (i.e. cost per product innovation) allowing for sample selection effects. Theory indicates that R&D unit cost will be influenced by scale issues and by the technological opportunities faced by the firm. Transaction costs encountered in research activities are allowed for and, in addition, consideration is given to issues of market structure which influence the choice of R&D mode without affecting the unit cost of internal or external R&D. The model is tested on data from a sample of over 500 UK manufacturing plants which have engaged in product innovation. The key determinants of R&D mode are the scale of plant and R&D input, and market structure conditions. In terms of the R&D cost equation, scale factors are again important and have a non-linear relationship with R&D unit cost. Specificities in physical and human capital also affect unit cost, but have no clear impact on the choice of R&D mode. There is no evidence of technological opportunity affecting either R&D cost or the internal/external decision.
