EUI-YouGov survey on European solidarity (2022)

1 data file, 1 documentation fileThe EUI-YouGov Survey on European solidarity (2022) was designed by the EUI 'Solidarity in Europe' research team (the data creators) and implemented by YouGov UK. It was conducted using an online interview administered to members of the YouGov Plc UK panel of 800,000+ individuals who agreed to take part in surveys. Emails are sent to panellists selected at random from the base sample. The e-mail invites participants to take part in a survey and provides a generic survey link. Once a panel member clicks on the link they are directed to the survey that they are most required for, according to the sample definition and quotas. (The sample definition could be (eg) "GB adult population" or a subset such as "GB adult females"). Invitations to surveys do not expire and respondents can be directed to any available survey. The responding sample is weighted to the profile of the sample definition to provide a representative reporting sample. The profile is normally derived from census data or, if not available from a census, from industry accepted data

Power, norms and institutional change in the European Union: the protection of the free movement of goods

How do institutions of the European Union change? Using an institutionalist approach, this article highlights the interplay between power, cognitive limits, and the normative order that underpins institutional settings and assesses their impact upon the process of institutional change. Empirical evidence from recent attempts to reinforce the protection of the free movement of goods in the EU suggests that, under conditions of uncertainty, actors with ambiguous preferences assess attempts at institutional change on the basis of the historically defined normative order which holds a given institutional structure together. Hence, path dependent and incremental change occurs even when more ambitious and functionally superior proposals are on offer

Insights into the Regulatory Characteristics of the Mycobacterial Dephosphocoenzyme A Kinase: Implications for the Universal CoA Biosynthesis Pathway

Being vastly different from the human counterpart, we suggest that the last enzyme of the Mycobacterium tuberculosis Coenzyme A biosynthetic pathway, dephosphocoenzyme A kinase (CoaE) could be a good anti-tubercular target. Here we describe detailed investigations into the regulatory features of the enzyme, affected via two mechanisms. Enzymatic activity is regulated by CTP which strongly binds the enzyme at a site overlapping that of the leading substrate, dephosphocoenzyme A (DCoA), thereby obscuring the binding site and limiting catalysis. The organism has evolved a second layer of regulation by employing a dynamic equilibrium between the trimeric and monomeric forms of CoaE as a means of regulating the effective concentration of active enzyme. We show that the monomer is the active form of the enzyme and the interplay between the regulator, CTP and the substrate, DCoA, affects enzymatic activity. Detailed kinetic data have been corroborated by size exclusion chromatography, dynamic light scattering, glutaraldehyde crosslinking, limited proteolysis and fluorescence investigations on the enzyme all of which corroborate the effects of the ligands on the enzyme oligomeric status and activity. Cysteine mutagenesis and the effects of reducing agents on mycobacterial CoaE oligomerization further validate that the latter is not cysteine-mediated or reduction-sensitive. These studies thus shed light on the novel regulatory features employed to regulate metabolite flow through the last step of a critical biosynthetic pathway by keeping the latter catalytically dormant till the need arises, the transition to the active form affected by a delicate crosstalk between an essential cellular metabolite (CTP) and the precursor to the pathway end-product (DCoA)

Explaining differentiation in European Union treaties

Since the early 1990s, European integration has become increasingly differentiated. Analysing the conditions under which member states make use of the opportunity to opt out of, or exclude other countries from, European integration, we argue that different explanations apply to treaty and accession negotiations, respectively. Threatening to block deeper integration, member states with strong national identities secure differentiations in treaty reform. In enlargement, in turn, old member states fear economic disadvantages and low administrative capacity and therefore impose differentiation on poor newcomers. Opt-outs from treaty revisions are limited to the area of core state powers, whereas they also occur in the market in the context of enlargement

MSH3 polymorphisms and protein levels affect CAG repeat instability in huntington's disease mice

Expansions of trinucleotide CAG/CTG repeats in somatic tissues are thought to contribute to ongoing disease progression through an affected individual's life with Huntington's disease or myotonic dystrophy. Broad ranges of repeat instability arise between individuals with expanded repeats, suggesting the existence of modifiers of repeat instability. Mice with expanded CAG/CTG repeats show variable levels of instability depending upon mouse strain. However, to date the genetic modifiers underlying these differences have not been identified. We show that in liver and striatum the R6/1 Huntington's disease (HD) (CAG)~100 transgene, when present in a congenic C57BL/6J (B6) background, incurred expansion-biased repeat mutations, whereas the repeat was stable in a congenic BALB/cByJ (CBy) background. Reciprocal congenic mice revealed the Msh3 gene as the determinant for the differences in repeat instability. Expansion bias was observed in congenic mice homozygous for the B6 Msh3 gene on a CBy background, while the CAG tract was stabilized in congenics homozygous for the CBy Msh3 gene on a B6 background. The CAG stabilization was as dramatic as genetic deficiency of Msh2. The B6 and CBy Msh3 genes had identical promoters but differed in coding regions and showed strikingly different protein levels. B6 MSH3 variant protein is highly expressed and associated with CAG expansions, while the CBy MSH3 variant protein is expressed at barely detectable levels, associating with CAG stability. The DHFR protein, which is divergently transcribed from a promoter shared by the Msh3 gene, did not show varied levels between mouse strains. Thus, naturally occurring MSH3 protein polymorphisms are modifiers of CAG repeat instability, likely through variable MSH3 protein stability. Since evidence supports that somatic CAG instability is a modifier and predictor of disease, our data are consistent with the hypothesis that variable levels of CAG instability associated with polymorphisms of DNA repair genes may have prognostic implications for various repeat-associated diseases

The New Politics of Global Tax Governance: Taking Stock a Decade After the Financial Crisis

The financial crisis of 2007–2009 is now broadly recognised as a once-in-a-generation inflection point in the history of global economic governance. It has also prompted a reconsideration of established paradigms in international political economy (IPE) scholarship. Developments in global tax governance open a window onto these ongoing changes, and in this essay we discuss four recent volumes on the topic drawn from IPE and beyond, arguing against an emphasis on institutional stability and analyses that consider taxation in isolation. In contrast, we identify unprecedented changes in tax cooperation that reflect a significant contemporary reconfiguration of the politics of global economic governance writ large. To develop these arguments, we discuss the links between global tax governance and four fundamental changes underway in IPE: the return of the state through more activist policies; the global power shift towards large emerging markets; the politics of austerity and populism; and the digitalisation of the economy

MutSβ exceeds MutSα in dinucleotide loop repair

The target substrates of DNA mismatch recognising factors MutSalpha (MSH2+MSH6) and MutSbeta (MSH2+MSH3) have already been widely researched. However, the extent of their functional redundancy and clinical substance remains unclear. Mismatch repair (MMR)-deficient tumours are strongly associated with microsatellite instability (MSI) and the degree and type of MSI seem to be dependent on the MMR gene affected, and is linked to its substrate specificities. Deficiency in MSH2 and MSH6 is associated with both mononucleotide and dinucleotide repeat instability. Although no pathogenic MSH3 mutations have been reported, its deficiency is also suggested to cause low dinucleotide repeat instability
