Regulation of the stem cell leukemia (SCL) gene: A tale of two fishes

The stem cell leukemia (SCL) gene encodes a tissue-specific basic helix–loop–helix (bHLH) protein with a pivotal role in hemopoiesis and vasculogenesis. Several enhancers have been identified within the murine SCL locus that direct reporter gene expression to subdomains of the normal SCL expression pattern, and long-range sequence comparisons of the human and murine SCL loci have identified additional candidate enhancers. To facilitate the characterization of regulatory elements, we have sequenced and analyzed 33 kb of the SCL genomic locus from the pufferfish Fugu rubripes, a species with a highly compact genome. Although the pattern of SCL expression is highly conserved from mammals to teleost fish, the genes flanking pufferfish SCL were unrelated to those known to flank both avian and mammalian SCL genes. These data suggest that SCL regulatory elements are confined to the region between the upstream and downstream flanking genes, a region of 65 kb in human and 8.5 kb in pufferfish. Consistent with this hypothesis, the entire 33-kb pufferfish SCL locus directed appropriate expression to hemopoietic and neural tissue in transgenic zebrafish embryos, as did a 10.4-kb fragment containing the SCL gene and extending to the 5′ and 3′ flanking genes. These results demonstrate the power of combining the compact genome of the pufferfish with the advantages that zebrafish provide for studies of gene regulation during development. Furthermore, the pufferfish SCL locus provides a powerful tool for the manipulation of hemopoiesis and vasculogenesis in vivo.

Molecular clock or erratic evolution? A tale of two genes.

We have investigated the evolution of glycerol-3-phosphate dehydrogenase (Gpdh). The rate of amino acid replacements is 1 x 10(-10)/site/year when Drosophila species are compared. The rate is 2.7 times greater when Drosophila and Chymomyza species are compared; and about 5 times greater when any of those species are compared with the medfly Ceratitis capitata. This rate of 5 x 10(-10)/site/year is also the rate observed in comparisons between mammals, or between different animal phyla, or between the three multicellular kingdoms. We have also studied the evolution of Cu,Zn superoxide dismutase (Sod). The rate of amino acid replacements is about 17 x 10(-10)/site/year when comparisons are made between dipterans or between mammals, but only 5 x 10(-10) when animal phyla are compared, and only 3 x 10(-10) when the multicellular kingdoms are compared. The apparent decrease by about a factor of 5 in the rate of SOD evolution as the divergence between species increases can be consistent with the molecular clock hypothesis by assuming the covarion hypothesis (namely, that the number of amino acids that can change is constant, but the set of such amino acids changes from time to time and from lineage to lineage). However, we know of no model consistent with the molecular clock hypothesis that would account for the increase in the rate of GPDH evolution as the divergence between species increases.

A few autoreactive cells in an autoimmune infiltrate control a vast population of nonspecific cells: a tale of smart bombs and the infantry.

Inflammatory infiltrates in tissue-specific autoimmune disease comprise a collection of T cells with specificity for an antigen in the target organ. These specific cells recruit a population of nonspecific T cells and macrophages. The rare tissue-specific T cells in the infiltrate have the capacity to regulate both the influx and the efflux of cells from the tissue. Administration of an altered peptide ligand for the specific T cell which triggers autoimmunity can lead to the regression of the entire inflammatory ensemble in a few hours. Interleukin 4 is a critical cytokine involved in the regression of the inflammatory infiltrate.

A tale of oversimplification and deregulation: the mainstream approach to labour market segmentation and the recent responses to the crisis in European countries. WP C.S.D.L.E. “Massimo D’Antona”.INT – 102/2013

After advocating flexibilization of non-standard work contracts for many years, some European and international institutions and several policy makers now indicate the standard employment relationship and its regulation as a cause of segmentation between the labour market of "guaranteed" insiders, employed under permanent contracts with effective protection against unfair dismissal, and the market of the “not-guaranteed” outsiders, working with non-standard contracts. Reforms of employment legislation are therefore being promoted and approved in different countries, allegedly aiming to balance the legal protection afforded to standard and non-standard workers. This article firstly argues that this approach is flawed as it oversimplifies reasons of segmentation as it concentrates on an “insiders-outsiders” discourse that cannot easily be transplanted in continental Europe. After reviewing current legislative changes in Italy, Spain and Portugal, it is then argued that lawmakers are focused on “deregulation” rather than “balancing protection” when approving recent reforms. Finally, the mainstream approach to segmentation and some of its derivative proposals, such as calls to introduce a “single permanent contract”, are called into question, as they seem to neglect the essential role of job protection in underpinning the effectiveness of fundamental and constitutional rights at the workplace.

Puerto Rico and Greece: A Tale of two defaults in a monetary union. CEPS High-Level Brief. 18 June 2015, Update 30 June 2015

It is widely argued that the problems of Greece in the eurozone derive not only from mistakes made by successive Greek governments, but from deep-seated problems with the design of the euro area. The euro area is judged to be incomplete because it does not have any fiscal shock absorbers, nor a federal transfer system, and, according to many, it has imposed senseless austerity on the country. The US, by contrast, is often held up as an example of a complete monetary union in this type of problem could not arise. However, the working of the US is much less perfect than it appears from afar. The ‘genuine’ economic and monetary union, which undoubtedly exists in the US, also has problems in dealing with low-performing states in terms of productivity and governance. Puerto Rico exemplifies these difficulties and shows that in such an integrated area similar problems, including a fiscal crisis can arise. Both Puerto Rico and Greece are very special and extreme cases within their respective unions, but the strength of a system can be measured by how it deals with these cases.

C'era una volta il doppiaggio - Analisi del doppiaggio della varietà diacronica nella versione spagnola del primo episodio della serie tv Once Upon A Time

L’argomento principale di questa tesi è il doppiaggio. Nel primo capitolo ci inoltriamo nel mondo della traduzione audiovisiva, concentrandoci sulla storia del doppiaggio e sui processi che servono per portare le opere in paesi dove non si parla la lingua originale dei film e delle serie tv. Il secondo capitolo introduce la serie tv americana targata ABC Once Upon A Time. Vengono presentati trama, personaggi, temi e alcuni dati sulla distribuzione della serie in Italia e in Spagna. Il terzo capitolo invece, ci porta nel pieno dell’analisi del doppiaggio in italiano e in spagnolo del primo episodio della serie attraverso la comparazione con l’originale inglese e lo studio della varietà diacronica attraverso le formule di cortesia, il lessico, la fraseologia, i sintagmi verbali e la morfologia. In conclusione, il nostro scopo è quello di dimostrare che la scelta traduttiva adottata dalla Spagna è diversa da quella italiana, quest’ultima più simile all’originale inglese.
