Marker-free transgenic white poplar (Populus alba L., cv 'Villafranca') plants, expressing the PsMT (A1) gene from Pisum sativum for a metallothionein-like protein, were produced by Agrobacterium tumefaciens-mediated transformation. The 35SCaMV-PsMT (A1)-NosT cassette was inserted into the ipt-type vector pMAT22. The occurrence of the abnormal ipt-shooty(More)
We have previously reported that stabilization of the G-quadruplex structures in the HIV-1 long terminal repeat (LTR) promoter suppresses viral transcription. Here we sought to develop new G-quadruplex ligands to be exploited as antiviral compounds by enhancing binding toward the viral G-quadruplex structures. We synthesized naphthalene diimide derivatives(More)
In animal cells, recent studies have emphasized the role played by DNA topoisomerase I (topo I) both as a cofactor of DNA repair complexes and/or as a damage sensor. All these functions are still unexplored in plant cells, where information concerning the relationships between DNA damage, PCD induction, and topo I are also limited. The main goal of this(More)
Recently it was demonstrated that the metabolism of both glycoproteins and sphingo(glyco)lipids is dependent upon the state of enterocytic differentiation of HT-29 cells. Furthermore, it was shown that undifferentiated HT-29 cells display an important autophagic sequestration, controlled by a heterotrimeric Gi3 protein. In order to correlate the metabolism(More)
The structure of the DRB1*03 gene has been interpreted as the product of a gene conversion event involving a DRB3 gene as donor and resulting in the introduction of two short segments of the DRB3 sequence into the DRB1 locus. The serological counterpart of this double insertion is the TR81 specificity. Consequently, the TR81-specifying sequences can reside(More)
Rhodococcus opacus R7 is a naphthalene-degrading microorganism which is also able to grow on o-xylene. This work describes the isolation and analysis of two new genomic regions in which genes involved in naphthalene (nar gene cluster) and salicylate (gen gene cluster) degradation are located. In the nar gene cluster we found: two genes encoding the large(More)
BACKGROUND Fluorescent sensing of G-quadruplex nucleic acids (G4s) is an effective strategy to elucidate their role in vitro and in vivo. Small molecule ligands have often been exploited, producing an emission light up upon binding. Naphthalene diimides (NDIs), although potent G4 binders exhibiting red-NIR fluorophores, have only been marginally exploited,(More)
OBJECTIVE According to evolutionary developmental (evo-devo) theory, the vomers are bones derived from the secondary palate. Growth of the palatine processes of the maxillae, including the precursors of vomer bones, results in midline fusion posteriorly to the primary palate, which forces the ascension of the vomer bones towards the primary nasal septum,(More)
