Global inhibition of class I and II histone deacetylases (HDACs) impairs angiogenesis. Herein, we have undertaken the identification of the specific HDAC(s) with activity that is necessary for the development of blood vessels. Using small interfering RNAs, we observed that HDAC7 silencing in endothelial cells altered their morphology, their migration, and their capacity to form capillary tube-like structures in vitro but did not affect cell adhesion, proliferation, or apoptosis. Among several factors known to be involved in angiogenesis, platelet-derived growth factor-B (PDGF-B) and its receptor (PDGFR-beta) were the most upregulated genes following HDAC7 silencing. We demonstrated that their increased expression induced by HDAC7 silencing was partially responsible for the inhibition of endothelial cell migration. In addition, we have also shown that treatment of endothelial cells with phorbol 12-myristate 13-acetate resulted in the exportation of HDAC7 out of the nucleus through a protein kinase C/protein kinase D activation pathway and induced, similarly to HDAC7 silencing, an increase in PDGF-B expression, as well as a partial inhibition of endothelial cell migration. Collectively, these data identified HDAC7 as a key modulator of endothelial cell migration and hence angiogenesis, at least in part, by regulating PDGF-B/PDGFR-beta gene expression. Because angiogenesis is required for tumor progression, HDAC7 may represent a rational target for therapeutic intervention against cancer. [less ▲]

Magnétique, l'affiche mobilisatrice pour la marche « Ensemble pour le climat et la solidarité » de ce 8 décembre à Bruxelles, ces humains nus convergeant vers notre planète à protéger. Superbe symbole qui ne doit pas nous faire oublier l'avertissement placé en tête d'affiche : « Ça commence ici ». « Ici », on nous le répète, c'est ma maison où je peux fermer le robinet, visser des ampoules économiques, baisser le chauffage, placer du double vitrage. Mais il y a un autre « ici » : notre beau coin d'Europe, nos villes et nos campagnes. Et là, pour Noël, le gouvernement wallon s'apprête à déposer un énorme cadeau dans nos petits souliers. Un truc neuf ? Non, vieux de presque un demi-siècle. Pas trop crade ? De luxe au contraire : 400 millions d'euros. Au moment de la conférence de Bali sur le changement climatique, ça a à voir avec le climat ? Mais oui ! Et c'est… ? Un permis de construire. Des canaux, des voies ferrées, des trams ? Non.

The imagination of the Netherlands comes close to a mythoid aggregate. The corpus transmits a superficial and picturesque imagery, based on tourist, pictorial and historical sources. The tourist conventions reinforce its stereotypical and anachronistic nature. The anachronism is also typical of the images borrowed from paintings of the Dutch school and a few art historians. Realism is most appreciated when poetically tinged, as with Rembrandt who reveals the boundary between dream and reality. History provides the authors with heroic or dramatic episodes, as well as with legends expressing national character or the struggle against the waters. At the dawn of the 20th century, the imagination of the Netherlands becomes more introspective. Societal changes and especially the industrialisation put the place of man in question. We have subjected three groups of images to a symbolical analysis. First, the group of miniaturised dwelling places, that express a unfulfilled desire for intimacy and a refuge out of time. Then, a group related to the painting as a mirror. These boundary images of an inaccessible space express the same disappointed desire. The sea images express progressive ideas as well as fear of mechanization at the same time. The illusion of the fantastic and the phantasmagoria make it possible to vanquish the setbacks suffered through the figures of intimacy. Against the industrialisation, against the changes of modern society, as well as against mass tourism, the author will oppose his imaginary experience of the world, and through his description will give a autoreferential image, revealing of his dreams and desires. L’imaginaire des Pays-Bas se rapproche d’un agrégat mythoïde. Le corpus véhicule une imagerie superficielle et pittoresque, construite autour de sources touristiques, picturales et historiques. Les conventions du tourisme en renforcent le caractère stéréotypée et anachronique. L’anachronisme caractérise aussi les images empruntées aux tableaux de l’école hollandaise et à quelques historiens de l’art. Le réalisme est surtout apprécié lorsqu’il est mêlé de poésie, comme chez Rembrandt qui révèle la frontière entre réel et rêve. L’Histoire fournit aux auteurs des épisodes héroïques ou dramatiques, et des légendes traduisant le caractère national ou la lutte contre les eaux. À l’aube du 20e siècle, l’imaginaire des Pays-Bas devient plus introspectif. Les changements sociétaux et surtout l’industrialisation remettent en cause la place de l’homme. Nous avons soumis trois groupes d’images à une analyse symbolique. D’abord celui des habitations miniaturisées, exprimant un désir d’intimité et de refuge hors du temps non satisfait. Le second se rattache à la peinture qui devient miroir. Ces images frontalières d’un espace inaccessible expriment le même désir déçu. Les images marines véhiculent à la fois des idées progressistes et la peur du machinisme. L’illusion du fantastique et de la fantasmagorie permet de surmonter les échecs rencontrés par les figures de l’intimité. À l’industrialisation, aux changements de la société moderne, au tourisme de masse aussi, l’auteur va opposer son expérience imaginaire du monde et à travers sa description, il va donner une image suiréférentielle révélatrice de ses rêves et désirs.

Epigenic regulation of gene transcription has recently been the subject of a fast growing interest particularly in the field of cancer. Enzymatic acetylation and deacetylation of the epsilon-amino groups of lysine residues from nucleosomal histones, represents major molecular epigenic mechanisms controlling gene expression. Histone deacetylases (HDACs) and histone acetyl transferases (HAT) represent the two families of enzymes in charge of the control of the level of acetylation of the histone tails. By removing the acetyl groups that abrogate the positive charge of the lysine residues that maintain the histone tails attached to DNA, HDACs repress transcription. In mammals, these latter enzymes form three groups of related enzymes based on their sequence homology and are classified as HDACs I, II and III. Global inhibition of the HDACs I and II groups results in cell growth arrest and apoptosis of cancer cells and alters tumor growth in in vivo experimental models. Their surprisingly low general toxicity and their impressive efficiency in preclinical cancer models has led to consider HDAC inhibitors as very promising new anticancer pharmacological agents. In this review, we attempt to give a comprehensive overview of the role and the involvement of HDAC in carcinogenesis as well as the current progress on the development of HDAC general and specific inhibitors as new cancer therapies.

Detección del BLV en muestras de semen de toros seropositivos Rossich Luciano1; Gutierrez Geronimo1; Rodriguez Sabrina1; Lefebvre Eduardo2; Trono Karina1; Dus Santos Maria Jose1. (1) Instituto de Virología, CICVyA, INTA-Castelar. CC 77. Buenos Aires, Argentina. (2) Centro de Inseminación Artificial La Elisa. Argentina. La principal ruta de transmisión del Virus de la Leucosis Bovina (BLV) es horizontal y esta dada por la exposición directa de fluidos biológicos contaminados con linfocitos infectados; principalmente sangre. A pesar de que antígenos virales y ADN proviral han sido identificados en semen, leche y calostro; la transmisión natural a través de estas secreciones no ha sido demostrada. El impacto sanitario y económico de la infección por BLV esta asociada con la interferencia en el movimiento internacional del ganado vacuno y su germoplasma. Datos experimentales soportan la improbabilidad de que el semen congelado de toros seropositivos para BLV puedan infectar vacas receptoras, sin embargo, aun hoy existen restricciones para la comercialización de semen de animales infectados. Dado que no existe vacuna ni tratamiento aplicable, la erradicación y control de la enfermedad esta exclusivamente basada en el diagnóstico temprano y segregación de los animales infectados. En este contexto la especificidad y la sensibilidad del diagnóstico utilizado constituyen un punto crítico. Hemos desarrollado previamente una PCR con alta sensibilidad y especificidad para detectar el genoma de BLV en muestras de semen congelado. El objetivo de este trabajo es el estudio del patrón de excreción natural de BLV en semen. Muestras de semen congelado de 30 toros seropositvos fueron analizados. Fue posible detectar ADN proviral en 144 de 752 muestras. La detección del genoma del BLV ha ocurrido en varias colecciones pero en forma alternada con períodos de no detección. Adicionalmente, la presencia de ARN proviral en sangre y muestras de sangre fue evaluada. [less ▲]
