  • 90 YEARS OF PROGESTERONE: Molecular mechanisms of progesterone receptor action on the breast cancer genome
    Beato, Miguel; Wright, Roni H.G.; Le Dily, François (BioScientifica, 2020)
    Gene regulation by steroid hormones has been at the forefront in elucidating the intricacies of transcriptional regulation in eukaryotes ever since the discovery by Karlson and Clever that the insect steroid hormone ecdysone ...
  • ATP, Mg2+, nuclear phase separation, and genome accessibility
    Wright, Roni H.G.; Le Dily, François; Beato, Miguel (Elsevier, 2019)
    Misregulation of the processes controlling eukaryotic gene expression can result in disease. Gene expression is influenced by the surrounding chromatin; hence the nuclear environment is also of vital importance. Recently, ...
  • CDK2-dependent activation of PARP-1 is required for hormonal gene regulation in breast cancer cells
    Wright, Roni H.G.; Castellano, Giancarlo; Bonet Martínez, Jaume, 1982-; Le Dily, François; Font Mateu, Jofre, 1977-; Ballaré, Cecilia Julia; Nacht, A. Silvina; Soronellas, Daniel; Oliva Miguel, Baldomero; Beato, Miguel (Cold Spring Harbor Laboratory Press (CSHL Press), 2012)
    Eukaryotic gene regulation implies that transcription factors gain access to genomic information via poorly understood processes involving activation and targeting of kinases, histone-modifying enzymes, and chromatin ...
  • Expression of oncogenic drivers in 3D cell culture depends on nuclear ATP synthesis by NUDT5
    Pickup, Katherine E.; Pardow, Felicitas; Carbonell-Caballero, Jose; Lioutas, Antonio, 1980-; Villanueva Cañas, José Luis, 1984-; Wright, Roni H.G.; Beato, Miguel (MDPI, 2019)
    The growth of cancer cells as oncospheres in three-dimensional (3D) culture provides a robust cell model for understanding cancer progression, as well as for early drug discovery and validation. We have previously described ...
  • Global signalling network analysis of luminal T47D breast cancer cells in response to progesterone
    Wright, Roni H.G.; Vastolo, Viviana; Quilez Oliete, Javier; Carbonell-Caballero, Jose; Beato, Miguel (Frontiers, 2022)
    Background: Breast cancer cells enter into the cell cycle following progestin exposure by the activation of signalling cascades involving a plethora of enzymes, transcription factors and co-factors that transmit the external ...
  • Hormone-control regions mediate steroid receptor-dependent genome organization
    Le Dily, François; Vidal, Enrique; Cuartero, Yasmina; Quilez Oliete, Javier; Nacht, A. Silvina; Vicent, Guillermo Pablo; Carbonell-Caballero, Jose; Sharma, Priyanka; Villanueva Cañas, José Luis, 1984-; Ferrari, Roberto; De Llobet, Lara Isabel; Verde, Gaetano; Wright, Roni H.G.; Beato, Miguel (Cold Spring Harbor Laboratory Press (CSHL Press), 2019)
    In breast cancer cells, some topologically associating domains (TADs) behave as hormonal gene regulation units, within which gene transcription is coordinately regulated in response to steroid hormones. Here we further ...
  • Hormone-induced repression of genes requires BRG1-mediated H1.2 deposition at target promoters
    Nacht, A. Silvina; Pohl, Andy, 1979-; Zaurín Quer, Roser; Soronellas, Daniel; Quilez Oliete, Javier; Sharma, Priyanka; Wright, Roni H.G.; Beato, Miguel; Vincent, Guillermo P. (EMBO Press, 2016)
    Eukaryotic gene regulation is associated with changes in chromatin compaction that modulate access to DNA regulatory sequences relevant for transcriptional activation or repression. Although much is known about the mechanism ...
  • MyoD induces ARTD1 and nucleoplasmic poly-ADP-ribosylation during fibroblast to myoblast transdifferentiation
    Bisceglie, Lavinia; Hopp, Ann-Katrin; Gunasekera, Kapila; Wright, Roni H.G.; Le Dily, François; Vidal, Enrique; Dall'Agnese, Alessandra; Caputo, Luca; Nicoletti, Chiara; Puri, Pier Lorenzo; Beato, Miguel; Hottiger, Michael O. (Elsevier, 2021)
    While protein ADP-ribosylation was reported to regulate differentiation and dedifferentiation, it has so far not been studied during transdifferentiation. Here, we found that MyoD-induced transdifferentiation of fibroblasts ...
  • Role of the NUDT enzymes in breast cancer
    Wright, Roni H.G.; Beato, Miguel (MDPI, 2021)
    Despite global research efforts, breast cancer remains the leading cause of cancer death in women worldwide. The majority of these deaths are due to metastasis occurring years after the initial treatment of the primary ...
  • Targeted NUDT5 inhibitors block hormone signaling in breast cancer cells
    Page, Brent D.G.; Wright, Roni H.G.; Font Mateu, Jofre, 1977-; Beato, Miguel; Helleday, Thomas (Nature Research, 2018)
    With a diverse network of substrates, NUDIX hydrolases have emerged as a key family of nucleotide-metabolizing enzymes. NUDT5 (also called NUDIX5) has been implicated in ADP-ribose and 8-oxo-guanine metabolism and was ...
  • The ADP-ribose hydrolase NUDT5 is important for DNA repair
    Qi, Hongyun; Wright, Roni H.G.; Beato, Miguel; Price, Brendan D. (Elsevier, 2022)
    DNA damage leads to rapid synthesis of poly(ADP-ribose) (pADPr), which is important for damage signaling and repair. pADPr chains are removed by poly(ADP-ribose) glycohydrolase (PARG), releasing free mono(ADP-ribose) ...
  • Unliganded progesterone receptor governs estrogen receptor gene expression by regulating DNA methylation in breast cancer cells
    Verde, Gaetano; De Llobet, Lara Isabel; Wright, Roni H.G.; Quilez Oliete, Javier; Peiró Sales, Sandra; Le Dily, François; Beato, Miguel (MDPI, 2018)
    Breast cancer prognosis and response to endocrine therapy strongly depends on the expression of the estrogen and progesterone receptors (ER and PR, respectively). Although much is known about ERα gene (ESR1) regulation ...
