  • A set of accessible enhancers enables the initial response of breast cancer cells to physiological progestin concentrations
    Zaurín Quer, Roser; Ferrari, Roberto; Nacht, A. Silvina; Carbonell-Caballero, Jose; Le Dily, François; Font Mateu, Jofre, 1977-; De Llobet, Lara Isabel; Vidal Ocabo, Enrique; Lioutas, Antonio, 1980-; Beato, Miguel; Vincent, Guillermo P. (Oxford University Press, 2021)
    Here, we report that in T47D breast cancer cells 50 pM progestin is sufficient to activate cell cycle entry and the progesterone gene expression program. At this concentration, equivalent to the progesterone blood levels ...
  • C/EBPα mediates the growth inhibitory effect of progestins on breast cancer cells
    Nacht, A. Silvina; Ferrari, Roberto; Zaurín Quer, Roser; Scabia, Valentina; Carbonell-Caballero, Jose; Le Dily, François; Quilez Oliete, Javier; Leopoldi, Alexandra; Brisken, Cathrin; Beato, Miguel; Vicent, Guillermo Pablo (EMBO Press, 2019)
    Steroid hormones are key gene regulators in breast cancer cells. While estrogens stimulate cell proliferation, progestins activate a single cell cycle followed by proliferation arrest. Here, we use biochemical and genome-wide ...
  • 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 ...
  • Nucleosome-driven transcription factor binding and gene regulation
    Ballaré, Cecilia Julia; Castellano, Giancarlo; Gaveglia, Laura; Althammer, Sonja Daniela; González-Vallinas Rostes, Juan, 1983-; Eyras Jiménez, Eduardo; Le Dily, François; Zaurín Quer, Roser; Soronellas, Daniel; Vicent, Guillermo Pablo; Beato, Miguel (Elsevier, 2013)
    In fission yeast cells, Cds1 is the effector kinase of the DNA replication checkpoint. We previously showed that when the DNA replication checkpoint is activated, the repressor Yox1 is phosphorylated and inactivated by ...
  • scTAM-seq enables targeted high-confidence analysis of DNA methylation in single cells
    Bianchi, Agostina; Scherer, Michael; Zaurín Quer, Roser; Quililan, Kimberly; Velten, Lars; Beekman, Renée (BioMed Central, 2022)
    Single-cell DNA methylation profiling currently suffers from excessive noise and/or limited cellular throughput. We developed scTAM-seq, a targeted bisulfite-free method for profiling up to 650 CpGs in up to 10,000 cells ...
  • Sequence-Dependent nucleosome positioning and chromatin remolleing of hormone-responsive genes
    Zaurín Quer, Roser (Universitat Pompeu Fabra, 2009-07-16)
    Evidències recents han remarcat la importància del paper de l'estructura de la cromatina i el posicionament de nucleosomes en processos cel·lulars bàsics com és la regulació de la transcripció gènica. L'avenç de noves ...
