The article deals with actions carried out by the Department of Environment and Regional Planning for the Basque Government in order to suppost the introduction of Local Agenda 21 in Basque municipalities. Special emphasis is placed on networking via intermunicipal cooperation. By way of acase study, the municipal area of Vitoria-Gasteiz -pioneer in the region for implementing the said Local Agenda 21- has been chosen, providing an opportunityt o make an initial assessment of its achievements and failures. ; El artículo aborda las actuaciones llevadas a cabo por el Departanlento de Ordenación del Territorio y Medio Ambiente del Gobierno Vasco para impulsar la implantación de la Agenda 21 Local en los municipios vascos. Se hace especial hincapié en la promoción del trabajo en red a través de la cooperación intermunicipal. Como estudio de caso, se ha elegido el rnunicipio de Vitoria-Gasteiz, pionero en la región en la puesta en marcha de dicha Agenda 21 Local, lo que permite realizar una primera valoración de sus logros y fracasos.

19 pags., 6 figs., 4 tabs. ; Establishing the interactome of the cancer-associated stress protein Nuclear Protein 1 (NUPR1), we found that it binds to several hundreds of proteins, including proteins involved in nuclear translocation, DNA repair, and key factors of the SUMO pathway. We demonstrated that the NUPR1 inhibitor ZZW-115, an organic synthetic molecule, competes with importins for the binding to the NLS region of NUPR1, thereby inhibiting its nuclear translocation. We hypothesized, and then proved, that inhibition of NUPR1 by ZZW-115 sensitizes cancer cells to DNA damage induced by several genotoxic agents. Strikingly, we found that treatment with ZZW-115 reduced SUMOylation of several proteins involved in DNA damage response (DDR). We further report that the presence of recombinant NUPR1 improved the SUMOylation in a cell-free system, indicating that NUPR1 directly stimulates the SUMOylation machinery. We propose that ZZW-115 sensitizes cancer cells to genotoxic agents by inhibiting the nuclear translocation of NUPR1 and thereby decreasing the SUMOylation-dependent functions of key proteins involved in the DDR. ; This work was supported by La Ligue Contre le Cancer, INCa, Canceropole PACA and INSERM to JI; Fondation ARC to PS.
