Global proteomic characterization of microdissected estrogen receptor positive breast tumors

We here describe two proteomic datasets deposited in ProteomeXchange via PRIDE partner repository [1] with dataset identifiers PXD000484 (defined as "training") and PXD000485 (defined as "test") that have been used for the development of a tamoxifen outcome predictive signature [2]. Both datasets comprised 56 fresh frozen estrogen receptor (ER) positive primary breast tumor specimens derived from

4-protein signature predicting tamoxifen treatment outcome in recurrent breast cancer

Estrogen receptor (ER) positive tumors represent the majority of breast malignancies, and are effectively treated with hormonal therapies, such as tamoxifen. However, in the recurrent disease resistance to tamoxifen therapy is common and a major cause of death. In recent years, in-depth proteome analyses have enabled identification of clinically useful biomarkers, particularly, when heterogeneity

The advantage of laser-capture microdissection over whole tissue analysis in proteomic profiling studies

Laser-capture microdissection (LCM) offers a reliable cell population enrichment tool and has been successfully coupled to MS analysis. Despite this, most proteomic studies employ whole tissue lysate (WTL) analysis in the discovery of disease biomarkers and in profiling analyses. Furthermore, the influence of tissue heterogeneity in WTL analysis, nor its impact in biomarker discovery studies have

Prognostic significance of nuclear expression of UMP-CMP kinase in triple negative breast cancer patients

We have previously identified UMP-CMP kinase (CMPK1) as a prognostic marker for triple negative breast cancer (TNBC) by mass spectrometry (MS). In this study we evaluated CMPK1 association to prognosis in an independent set of samples by immunohistochemistry (IHC) and assessed biological pathways associated to its expression through gene set enrichment analysis (GSEA). A total of 461 TNBC paraffin

Collective Action on Forest Governance: An Institutional Analysis of the Cambodian Community Forest System

Decentralisation in Cambodia has long been propagated as a means to enhance local engagement with governance structures. But in the forestry sector, even limited devolution of powers often constrains local user groups with excessive bureaucratic burdens. In addition, entrenched political economy interests tend to inhibit effective governance. To investigate the apparent institutional malaise that

Vertical Extension of Buildings

Many policy targets have been developed with the aim of reaching a more sustainable development; more specifically, thestudied policies target energy use and urban growth. For example, by 2050 the aim is that the European Union will havereduced its greenhouse emissions by 90%. Examples of policy targets regarding urban growth can be found in many ofthe larger cities, as they have developed plans fMany policy targets have been developed with the aim of reaching a more sustainable development; more specifically, thestudied policies target energy use and urban growth.

Non-Lamellar lipid assembly at interfaces : Controlling layer structure by responsive nanogel particles

Biological membranes do not only occur as planar bilayer structures, but depending on the lipid composition, can also curve into intriguing threedimensional structures. In order to fully understand the biological implications as well as to reveal the full potential for applications, e.g. for drug delivery and other biomedical devices, of such structures, well-defined model systems are required. He

Modeling of a Gradient Porosity SOFC Anode using the Lattice Boltzmann Method

The solid oxide fuel cell (SOFC) is an electrochemical device that converts the chemical energy present in reactant fuels into electrical energy and heat. Such conversion is given by the electrochemical reactions that occur inside the fuel cells when the reactant gases reach the so-called Three-phase Boundary (TPB). However, before the reactant gases can reach the TPBs, they have to pass through a

OpenSAW: Open Security Analysis Workbench

Software is today often composed of many sourced components, which potentially contain security vulnerabilities, and therefore require testing before being integrated. Tools for automated test case generation, for example, based on white-box fuzzing, are beneficial for this testing task. Such tools generally explore limitations of the specific underlying techniques for solving problems related to,

The negative effects on mental health of being in a non-desired occupation in an increasingly precarious labour market

Precarious employment has been associated with poor mental health. Moreover, increasing labour market precariousness may cause individuals to feel ‘locked-in’, in non-desired workplaces or occupations, out of fear of not finding a new employment. This could be experienced as a ‘loss of control’, with similar negative health consequences. It is plausible that the extent to which being in a non-desi

Family aggression in a social lizard

The evolution of family living is underpinned by conflict and cooperation between family members. While family groups can be maintained by reducing conflict between parents and offspring, interactions between siblings may play an equally important role. Here, we compared the level of aggressive interactions between siblings to that between parents and their offspring in the family living skink Lio

The acculturation in Sweden of adolescents of Iranian and Yugoslavian origin

Ethnic acculturation in a sample of 19-year-old individuals of Yugoslavian and Iranian origin in contemporary Sweden was studied, with a focus on how acculturation is contingent on social structure and social context. Acculturation was measured as orientation to the majority and the parental culture of origin. The results suggest, first, that the two dimensions are weakly but positively correlated

Heparan sulfate upregulates platelet-derived growth factor receptors on human lung fibroblasts

Heparan sulfate is a molecule that possesses a large structural variability and which has been shown to inhibit the proliferation of fibroblasts in vitro. The aim of this study was to determine whether the anti-proliferative effects of heparan sulfate were exerted by regulation of the activity of the platelet-derived growth factor and/or of the platelet-derived growth factor receptors. Both l-idur

Altered expression of small proteoglycans, collagen, and transforming growth factor-beta 1 in developing bleomycin-induced pulmonary fibrosis in rats

The development of bleomycin-induced pulmonary fibrosis in rats was studied over a period of 21 d after an intratracheal instillation of bleomycin. The expression of three small proteoglycans (biglycan, decorin, and fibromodulin), collagen III and TGF-beta 1 was studied by RNA-transfer blot analysis. The proteoglycans were also studied by SDS-polyacrylamide gel electrophoresis and Western blots. T

Lokal arbetsmarknadspolitik : Vem gör vad, hur och för vem?

Syftet i forskningsrapporten är att analysera om och i så fall hur statlig och kommunal arbetsmarknadspolitik överlappar varandra samt om arbetslösa riskerar att varken aktualiseras inom kommunal eller statlig arbetsmarknadspolitik. Forskningsrapporten omfattar en kunskapsöversikt av forskning om kommunal arbetsmarknadspolitik samt en intervjustudiemed nyckelpersoner inom statlig och kommunal arbe

A deterministic method for estimating free energy genetic network landscapes with applications to cell commitment and reprogramming paths

Depicting developmental processes as movements in free energy genetic landscapes is an illustrative tool. However, exploring such landscapes to obtain quantitative or even qualitative predictions is hampered by the lack of free energy functions corresponding to the biochemical Michaelis– Menten or Hill rate equations for the dynamics. Being armed with energy landscapes defined by a network and its

Differential expressions of mRNA for proteoglycans, collagens and transforming growth factor-beta in the human cervix during pregnancy and involution

During pregnancy and involution, an extensive remodelling of the human cervical connective tissue occurs. This cervical ripening is one of the most pronounced physiological remodelling processes known in human connective tissue. To investigate how the remodelling is accomplished, the levels of mRNA for collagen I and III, versican and three small proteoglycans, biglycan, decorin and fibromodulin,
