Characterization of N-cadherin association to lipid rafts in melanoma

RESUME La peau est un organe complex composé de deux parties distinctes: l'épiderme et le derme, séparé par une membrane basale. Dans la couche basale de l'épiderme, les melanocytes synthétisent la mélanine dans des mélanosomes. Les mélanosomes sont ensuite transportés des mélanocytes vers les kératinocytes, protégeant ainsi la peau des dégâts dus aux radiations U.V. La E-cadhérine assure l'adhésion entre les mélanocytes et les kératinocytes. Au cours de la transformation du mélanocyte en cellule malignes, les mélanocytes perdent l'expression de la E-cadhérine et, simultanément, se mettent à exprimer la N-cadhérine, ce phénomène est nommé « cadherin switch ». La perte de l'expression de la E-cadhérine permet au mélanocytes d'échapper au contrôle des kératinocytes, tandis que l'expression de la N-cadhérine promeut l'invasion métastasique des cellules de mélanome. Préalablement, nous avons trouvé qu'une fraction de la N-cadhérine était localisée les microdomaines membranaires spécialisés, enrichi en cholestérol et en glycosphingolipides, appelés « lipid rafts ». Une des particularité des « lipid rafts » est qu'ils sont riches en molécules permettant la transmission de signaux d'activation. De plus, des travaux récents rapportent qu'un sous-type de « lipid rafts » appelé caveolae pourrai contribuer à la progression tumorale. S'appuyant sur le rôle prépondérant de la N-cadhérine dans la progression du mélanome ainsi que sur sa présence dans les « lipid rafts », nous avons émis l'hypothèse que l'association de la N-cadhérine avec les « lipid rafts » pourrai contribuer à la progression du mélanome. Le but de ce projet à été de caractériser l'association de la Ncadhérine avec les « lipid rafts » au cours de la progression du mélanome. Au moyen de lignées cellulaires humaines, dérivées de mélanomes à différents stades de progression, nous avons trouvé que (1) la N-cadhérine est partiellement associée aux «lipid rafts » dans six lignées dérivées de mélanome en phase avancée de progression et dans des tumeurs expérimentales, mais pas dans deux lignées dérivées de mélanome à un stade plus précoce ; (2) l'association de la N-cadhérine dans les « lipid rafts » ne dépent pas de son niveau d'expression ; (3) la E-cadhérine n'est pas présente dans les « lipid rafts »d'une lignée de cellule de mélanome ayant conservé l'expression de la E-cadhérine ; (4) la localisation de la N-cadhérine dans les « lipid rafts »n'est pas modulée par les facteurs de croissance bFGF, IGF-I, et HRG1-β1, ni par des voies de signalisation impliquant MEK, PKA, les kinases de la famille Src, et PI3K ; (5) l'association de la N-cadhérine avec les « lipid rafts » n'est pas requise pour la stabilisation des jonctions adhérentes et n'est pas perturbée par la destruction de ces dernières ; (6) la N-cadhérine dans les « lipid rafts » forme un complexe avec β-caténine, p 120ctn et α-caténine. En conclusion, cette étude originale montre pour la première fois que dans des cellules de mélanome agressifs, une fraction de la N-cadhérine est localisée dans les « lipid rafts » en association avec β-caténine, p 120ctn et α-caténine. Comme la présence de la N-cadhérine dans les « lipid rafts » ne contribue pas à la formation de jonction adhérentes, cette étude suggère une nouvelle fonction pour la N-cadhérine dans les « lipid rafts ». SUMMARY Human skin is a complex organ composed of two layers separated by a basement membrane: the epidermis and the dermis. In the basal layer of the epidermis, the melanin-producing cells of the skin, the melanocytes deliver melanin-containing melanosomes to keratinocytes, thereby protecting the epidermis and the dermis from the deleterious effects of ultraviolet light. Melanocytes physically interact with keratinocytes through E-cadherin-mediated adhesion. During malignant transformation into melanoma cells, melanocytes lose E-cadherin expression and concomitantly gain expression of N-cadherin, a phenomenon referred to as "cadherin switch". Loss of E-cadherin allows melanocytes to escape the regulatory effects of neighbouring keratinocytes, while gain of N-cadherin expression promotes migration, invasion and metastatic abilities of melanoma cells. In preliminary experiments, we found that a fraction of N-cadherin localized to specialized membrane microdomains enriched in cholesterol- and glycosphingolipid, called lipid rafts. One particular feature of lipid rafts is that they are rich in signalling molecules and they possibly modulate transmembrane signalling events. Moreover, recent reports suggested that a specialized type of rafts called caveolae might contribute to tumor progression. Based on the documented role of N-cadherin in melanoma progression and its presence in lipid rafts of melanoma cells, we raised the hypothesis that the association of N-cadherin with lipid rafts might be relevant to melanoma progression. The aim of this project was to characterize N-cadherin associated to lipid rafts during melanoma progression. Using human melanoma cell lines derived from melanoma at different stages of progression, we found that (1) N-cadherin is partly associated to lipid rafts in six cell lines derived from melanomas at late stages of progression and in experimental tumors, but not in two melanoma cell lines derived from early stages; (2) N-cadherin targeting to lipid rafts does not depend on its expression level; (3) E-cadherin is not localized in lipid rafts of a melanoma cell line that retained E-cadherin expression; (4) N-cadherin localization to lipid rafts is not modulated by the growth factors bFGF, IGF-I, and HRG1-β1, nor by MEK-, PKA-, Src family kinases-, and PI3K-mediated signalling events; (5) the association of N-cadherin with lipid rafts is not required for adherens junctions stability nor it is perturbed by adherens junctions disruption; (6) N-cadherin in lipid rafts is in complex with β-catenin, p 120ctm and α-catenin. In conclusion, this study provides original evidence that in aggressive melanoma cells a pool of N-cadherin is localized in lipid rafts in association with β-catenin, p 120 and α-catenin. The presence of N-cadherin in lipid rafts independently of its involvement in adherens junctions formation, suggests a possible new role for N-cadherin recruited to lipid rafts. Further studies investigating the biological meaning of this localization promise to uncover new properties of this molecule.

Evaluation d'une association regionale de prevention du suicide en Suisse = Evaluation of a regional association for suicide prevention in Switzerland

This article discusses the evaluation of Stop Suicide, a regional association active in youth suicide prevention in Switzerland. The first part of the article presents and discusses the activities of Stop Suicide and its national context, characterized by an absence of a general national suicide prevention program. The second part specifically focuses on the evaluation of Stop Suicide, based on interviews with the members of the association's network. The evaluation reported an assessment carried out regarding the members' general perceptions about the association and its collaborations. The article suggests the possibility of creating a branch for coordinating regional suicide prevention, and it highlights the need to evaluate the impact and effects of the activities on the population concerned, youth

Stratification by smoking status reveals an association of CHRNA5-A3-B4 genotype with body mass index in never smokers.

We previously used a single nucleotide polymorphism (SNP) in the CHRNA5-A3-B4 gene cluster associated with heaviness of smoking within smokers to confirm the causal effect of smoking in reducing body mass index (BMI) in a Mendelian randomisation analysis. While seeking to extend these findings in a larger sample we found that this SNP is associated with 0.74% lower body mass index (BMI) per minor allele in current smokers (95% CI -0.97 to -0.51, P = 2.00 × 10(-10)), but also unexpectedly found that it was associated with 0.35% higher BMI in never smokers (95% CI +0.18 to +0.52, P = 6.38 × 10(-5)). An interaction test confirmed that these estimates differed from each other (P = 4.95 × 10(-13)). This difference in effects suggests the variant influences BMI both via pathways unrelated to smoking, and via the weight-reducing effects of smoking. It would therefore be essentially undetectable in an unstratified genome-wide association study of BMI, given the opposite association with BMI in never and current smokers. This demonstrates that novel associations may be obscured by hidden population sub-structure. Stratification on well-characterized environmental factors known to impact on health outcomes may therefore reveal novel genetic associations.

Rules vs. political discretion: evidence from constitutionally guaranteed transfers to local governments in Brazil

Can rules be used to shield public resources from political interference? The Brazilian constitution and national tax code stipulate that revenue sharing transfers to municipal governments be determined by the size of counties in terms of estimated population. In this paper I document that the population estimates which went into the transfer allocation formula for the year 1991 were manipulated, resulting in significant transfer differentials over the entire 1990's. I test whether conditional on county characteristics that might account for the manipulation, center-local party alignment, party popularity and the extent of interparty fragmentation at the county level are correlated with estimated populations in 1991. Results suggest that revenue sharing transfers were targeted at right-wing national deputies in electorally fragmented counties as well as aligned local executives.

Association of candidate genes with phenotypic traits relevant to anorexia nervosa.

This analysis is a follow-up to an earlier investigation of 182 genes selected as likely candidate genetic variations conferring susceptibility to anorexia nervosa (AN). As those initial case-control results revealed no statistically significant differences in single nucleotide polymorphisms, herein, we investigate alternative phenotypes associated with AN. In 1762 females, using regression analyses, we examined the following: (i) lowest illness-related attained body mass index; (ii) age at menarche; (iii) drive for thinness; (iv) body dissatisfaction; (v) trait anxiety; (vi) concern over mistakes; and (vii) the anticipatory worry and pessimism versus uninhibited optimism subscale of the harm avoidance scale. After controlling for multiple comparisons, no statistically significant results emerged. Although results must be viewed in the context of limitations of statistical power, the approach illustrates a means of potentially identifying genetic variants conferring susceptibility to AN because less complex phenotypes associated with AN are more proximal to the genotype and may be influenced by fewer genes.

Rules of origin : from analysis to reform

General Introduction This thesis can be divided into two main parts :the first one, corresponding to the first three chapters, studies Rules of Origin (RoOs) in Preferential Trade Agreements (PTAs); the second part -the fourth chapter- is concerned with Anti-Dumping (AD) measures. Despite wide-ranging preferential access granted to developing countries by industrial ones under North-South Trade Agreements -whether reciprocal, like the Europe Agreements (EAs) or NAFTA, or not, such as the GSP, AGOA, or EBA-, it has been claimed that the benefits from improved market access keep falling short of the full potential benefits. RoOs are largely regarded as a primary cause of the under-utilization of improved market access of PTAs. RoOs are the rules that determine the eligibility of goods to preferential treatment. Their economic justification is to prevent trade deflection, i.e. to prevent non-preferred exporters from using the tariff preferences. However, they are complex, cost raising and cumbersome, and can be manipulated by organised special interest groups. As a result, RoOs can restrain trade beyond what it is needed to prevent trade deflection and hence restrict market access in a statistically significant and quantitatively large proportion. Part l In order to further our understanding of the effects of RoOs in PTAs, the first chapter, written with Pr. Olivier Cadot, Celine Carrère and Pr. Jaime de Melo, describes and evaluates the RoOs governing EU and US PTAs. It draws on utilization-rate data for Mexican exports to the US in 2001 and on similar data for ACP exports to the EU in 2002. The paper makes two contributions. First, we construct an R-index of restrictiveness of RoOs along the lines first proposed by Estevadeordal (2000) for NAFTA, modifying it and extending it for the EU's single-list (SL). This synthetic R-index is then used to compare Roos under NAFTA and PANEURO. The two main findings of the chapter are as follows. First, it shows, in the case of PANEURO, that the R-index is useful to summarize how countries are differently affected by the same set of RoOs because of their different export baskets to the EU. Second, it is shown that the Rindex is a relatively reliable statistic in the sense that, subject to caveats, after controlling for the extent of tariff preference at the tariff-line level, it accounts for differences in utilization rates at the tariff line level. Finally, together with utilization rates, the index can be used to estimate total compliance costs of RoOs. The second chapter proposes a reform of preferential Roos with the aim of making them more transparent and less discriminatory. Such a reform would make preferential blocs more "cross-compatible" and would therefore facilitate cumulation. It would also contribute to move regionalism toward more openness and hence to make it more compatible with the multilateral trading system. It focuses on NAFTA, one of the most restrictive FTAs (see Estevadeordal and Suominen 2006), and proposes a way forward that is close in spirit to what the EU Commission is considering for the PANEURO system. In a nutshell, the idea is to replace the current array of RoOs by a single instrument- Maximum Foreign Content (MFC). An MFC is a conceptually clear and transparent instrument, like a tariff. Therefore changing all instruments into an MFC would bring improved transparency pretty much like the "tariffication" of NTBs. The methodology for this exercise is as follows: In step 1, I estimate the relationship between utilization rates, tariff preferences and RoOs. In step 2, I retrieve the estimates and invert the relationship to get a simulated MFC that gives, line by line, the same utilization rate as the old array of Roos. In step 3, I calculate the trade-weighted average of the simulated MFC across all lines to get an overall equivalent of the current system and explore the possibility of setting this unique instrument at a uniform rate across lines. This would have two advantages. First, like a uniform tariff, a uniform MFC would make it difficult for lobbies to manipulate the instrument at the margin. This argument is standard in the political-economy literature and has been used time and again in support of reductions in the variance of tariffs (together with standard welfare considerations). Second, uniformity across lines is the only way to eliminate the indirect source of discrimination alluded to earlier. Only if two countries face uniform RoOs and tariff preference will they face uniform incentives irrespective of their initial export structure. The result of this exercise is striking: the average simulated MFC is 25% of good value, a very low (i.e. restrictive) level, confirming Estevadeordal and Suominen's critical assessment of NAFTA's RoOs. Adopting a uniform MFC would imply a relaxation from the benchmark level for sectors like chemicals or textiles & apparel, and a stiffening for wood products, papers and base metals. Overall, however, the changes are not drastic, suggesting perhaps only moderate resistance to change from special interests. The third chapter of the thesis considers whether Europe Agreements of the EU, with the current sets of RoOs, could be the potential model for future EU-centered PTAs. First, I have studied and coded at the six-digit level of the Harmonised System (HS) .both the old RoOs -used before 1997- and the "Single list" Roos -used since 1997. Second, using a Constant Elasticity Transformation function where CEEC exporters smoothly mix sales between the EU and the rest of the world by comparing producer prices on each market, I have estimated the trade effects of the EU RoOs. The estimates suggest that much of the market access conferred by the EAs -outside sensitive sectors- was undone by the cost-raising effects of RoOs. The chapter also contains an analysis of the evolution of the CEECs' trade with the EU from post-communism to accession. Part II The last chapter of the thesis is concerned with anti-dumping, another trade-policy instrument having the effect of reducing market access. In 1995, the Uruguay Round introduced in the Anti-Dumping Agreement (ADA) a mandatory "sunset-review" clause (Article 11.3 ADA) under which anti-dumping measures should be reviewed no later than five years from their imposition and terminated unless there was a serious risk of resumption of injurious dumping. The last chapter, written with Pr. Olivier Cadot and Pr. Jaime de Melo, uses a new database on Anti-Dumping (AD) measures worldwide to assess whether the sunset-review agreement had any effect. The question we address is whether the WTO Agreement succeeded in imposing the discipline of a five-year cycle on AD measures and, ultimately, in curbing their length. Two methods are used; count data analysis and survival analysis. First, using Poisson and Negative Binomial regressions, the count of AD measures' revocations is regressed on (inter alia) the count of "initiations" lagged five years. The analysis yields a coefficient on measures' initiations lagged five years that is larger and more precisely estimated after the agreement than before, suggesting some effect. However the coefficient estimate is nowhere near the value that would give a one-for-one relationship between initiations and revocations after five years. We also find that (i) if the agreement affected EU AD practices, the effect went the wrong way, the five-year cycle being quantitatively weaker after the agreement than before; (ii) the agreement had no visible effect on the United States except for aone-time peak in 2000, suggesting a mopping-up of old cases. Second, the survival analysis of AD measures around the world suggests a shortening of their expected lifetime after the agreement, and this shortening effect (a downward shift in the survival function postagreement) was larger and more significant for measures targeted at WTO members than for those targeted at non-members (for which WTO disciplines do not bind), suggesting that compliance was de jure. A difference-in-differences Cox regression confirms this diagnosis: controlling for the countries imposing the measures, for the investigated countries and for the products' sector, we find a larger increase in the hazard rate of AD measures covered by the Agreement than for other measures.
