Antitumor effects of dehydroxymethylepoxyquinomicin, a novel nuclear factor-kappaB inhibitor, in human liver cancer cells are mediated through a reac…
2009
Activation of the nuclear transcription factor-kappa B (NF-kappa B) has been implicated in liver tumorigenesis. We evaluated the effects of a novel NF-kappa B inhibitor, dehydroxymethylepoxyquinomicin (DHMEQ), in two human liver cancer cell lines HA22T/VGH and HuH-6. DHMEQ treatment dose dependently decreased the DNA-binding capacity of the NF-kappa B p65 subunit, inhibited cell growth and proliferation, and increased apoptosis as shown by caspase activation, release of cytochrome c, poly(ADP-ribose) polymerase cleavage, and down-regulation of survivin. DHMEQ also induced a dose-dependent activation of mitogen-activated protein kinase kinase/extracellular signal-regulated kinase signaling, …
Getting Docking into Shape Using Negative Image-Based Rescoring
2019
The failure of default scoring functions to ensure virtual screening enrichment is a persistent problem for the molecular docking algorithms used in the structure-based drug discovery. To remedy this problem, elaborate rescoring and post-processing schemes have been developed with a varying degree of success, specificity, and cost. The negative imagebased rescoring (R-NiB) has been shown to improve the flexible docking performance markedly with a variety of drug targets.The yield improvement is achieved by comparing the alternative docking poses against the negative image of the target protein’s ligand-binding cavity. In other words, the shape and electrostatics of the binding pocket is dir…
Targeting SARS-CoV-2 RBD Interface: a Supervised Computational Data-Driven Approach to Identify Potential Modulators
2020
Coronavirus disease 2019 (COVID-19) has spread out as a pandemic threat affecting over 2 million people. The infectious process initiates via binding of SARS-CoV-2 Spike (S) glycoprotein to host angiotensin-converting enzyme 2 (ACE2). The interaction is mediated by the receptor-binding domain (RBD) of S glycoprotein, promoting host receptor recognition and binding to ACE2 peptidase domain (PD), thus representing a promising target for therapeutic intervention. Herein, we present a computational study aimed at identifying small molecules potentially able to target RBD. Although targeting PPI remains a challenge in drug discovery, our investigation highlights that interaction between SARS-CoV…
Bioassays to monitor taspase1 function for the identification of pharmacogenetic inhibitors
2011
Background Threonine Aspartase 1 (Taspase1) mediates cleavage of the mixed lineage leukemia (MLL) protein and leukemia provoking MLL-fusions. In contrast to other proteases, the understanding of Taspase1's (patho)biological relevance and function is limited, since neither small molecule inhibitors nor cell based functional assays for Taspase1 are currently available. Methodology/Findings Efficient cell-based assays to probe Taspase1 function in vivo are presented here. These are composed of glutathione S-transferase, autofluorescent protein variants, Taspase1 cleavage sites and rational combinations of nuclear import and export signals. The biosensors localize predominantly to the cytoplasm…
Conflicts over the provision and payment of wages of the "pavordías" of the University of Valencia during the second half of the seventeenth century
2002
Este artículo analiza las causas que influyeron en la dificultad de dotar las pavordías de la Universidad de Valencia en la segunda mitad del seiscientos. Los incrementos salariales de los pavordes, los gastos provocados por los continuos pleitos con los canónigos, la disminución de la renta de la pavordía, la reclamación por la Cámara Apostólica de los quindenios correspondientes y el desacuerdo entre la Ciudad y los pavordes respecto al estado de las cuentas se conjugaron para provocar la paralización de la provisión de preposituras. Situación a la que sólo la firma de las sucesivas concordias de 1669 y 1680 entre la Ciudad y los pavordes consiguió poner fin. This article analyzes the cau…
Serve ancora ucidere i tiranni? A proposito di Ps. Quint. decl. min. 253
2018
The paper deals with Ps. Quint. decl. min. 253; in the text, concerning one of the best-known themes of the declamatory literature, a tyrannicide, after killing a tyrant, asks the community for approval of a rogatio in order to be sent to the tyrant of the nearby city. The declamation focuses on a hero willing to put the salvation of the community before his own, a theme certainly usual in Latin thought, but which traces new interpretative ways in the declamatory culture.
Le declamazioni minori attribuite a Quintiliano I (244-292)
2019
The volume includes a textual revision, the first Italian translation and a commentary on the Minor Declamations 244-292 ascribed to Quintilian. The commentary, non only addresses the many critical issues posed by a particularly complex text, but also exploits the results of the strand studies on declamation that has been flourished in the last 20 years involving rhetorical as well as literary and anthropological perspective. The introductory essay by Lucia Pasetti (coordinator of the PRIN project supporting the research) focuses on the issues of textual typology and relationship with literary and juridical tradition and addresses the thorny question of Quintilian authorship. Il volume cont…
Le Declamazioni Minori dello Pseudo-Quintiliano. Discorsi immaginari tra letteratura e diritto
2016
Dedicated to the Minor Declamations ascribed to Quintilian, this volume explores different aspects of this ancient school book: a manual introducing the reader to the daily work of a master rhetorician, as well as an instrument to explore ancient imagery and the close relationship connecting rhetoric, literature and law
