Preomic profile of BxPC-3 cells after treatment with BRC4

BRCA2 and RAD51 are two proteins that play a central role in homologous recombination (HR) and DNA double strand break (DSB) repair. BRCA2 assists RAD51 fibrillation and defibrillation through binding with its eight BRC repeats, with BRC4 being one of the ...

Cell-autonomous inflammation of BRCA1-deficient ovarian cancers drives both tumor-intrinsic immunoreactivity and immune resistance via STING

Julien Dorier, George Coukos, Christian Iseli, Mauro Delorenzi, Alizée Jéléna Grimm, Giovanni Ciriello, Alexandre Harari, Marco Mina

In this study, we investigate mechanisms leading to inflammation and immunoreactivity in ovarian tumors with homologous recombination deficiency (HRD). BRCA1 loss is found to lead to transcriptional reprogramming in tumor cells and cell-intrinsic inflammat ...

Organometallic Glutathione S-Transferase Inhibitors

Paul Joseph Dyson, Rosario Scopelliti, Emilia Paunescu, Mylène Soudani

A new family of organometallic p-cymene ruthenium(II) and osmium(II) complexes conjugated to ethacrynic acid, a glutathione transferase (GST) inhibitor, is reported. The ethacrynic acid moiety (either one or two) is tethered to the arene ruthenium(II) and ...

Differential Cytotoxicity, Cellular Uptake, Apoptosis and Inhibition of BRCA1 Expression of BRCA1-Defective and Sporadic Breast Cancer Cells Induced by an Anticancer Ruthenium(II)-Arene Compound, RAPTA-EA1

Paul Joseph Dyson

Background: The RAPTA-EA1 complex [ruthenium(II)-arene 1,3,5-triaza-7-phosphaadamantane (pta) complex with an arene-tethered ethacrynic acid ligand] has been reported to overcome drug resistance that developed due to the current use of platinum-based treat ...

Identification of a Novel Wnt Inhibitor

Cancer cells are embedded in a microenvironment composed of stromal cells, such as fibroblasts, endothelial cells, infiltrating immune cells, as well as non-cellular compartments such as the extracellular matrix and secreted soluble factors. For successful ...

Loss of Cutaneous TSLP-Dependent Immune Responses Skews the Balance of Inflammation from Tumor Protective to Tumor Promoting

Freddy Radtke, Ute Koch, Matteo Di Piazza, Craig Nowell

Inflammation can promote or inhibit cancer progression. In this study we have addressed the role of the proinflammatory cytokine thymic stromal lymphopoietin (TSLP) during skin carcinogenesis. Using conditional loss- and gain-of-function mouse models for N ...

Interference between PARPs and SIRT1: a novel approach to healthy ageing?

Johan Auwerx, Carlos Canto Alvarez

Poly(ADP-ribosyl) polymerases (PARPs) have traditionally been linked to chromosome maintenance and DNA repair. Recent findings identify PARPs as key modulators of metabolism through their influence on SIRT1 activity, hinting to a possible role of PARPs as ...

Epithelial Pten is dispensable for intestinal homeostasis but suppresses adenoma development and progression after Apc mutation

PTEN acts as a tumor suppressor in a range of tissue types and has been implicated in the regulation of intestinal stem cells. To study Pten function in the intestine, we used various conditional transgenic strategies to specifically delete Pten from the m ...

Development of new anticancer agents based on [alpha]-mannosidase inhibition

Hélène Fiaux

Enzymes that are involved in the synthesis and processing of oligosaccharides, such as glycosidases, are important catalysts for the specific assembly of oligosaccharide structures on proteins. Design and preparation of selective inhibitors of these enzyme ...
