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 ...
ELSEVIER2023Multiomic analysis of HER2-enriched and AR-positive breast carcinoma with apocrine differentiation and an oligometastatic course: a case report
Breast carcinoma is the most prevalent cancer among women globally. It has variable clinical courses depending on the stage and clinical-biological features. This case report describes a 56-year-old female with invasive breast cancer without estrogen or pr ...
FRONTIERS MEDIA SA2023Epithelial-mesenchymal plasticity determines estrogen receptor positive breast cancer dormancy and epithelial reconversion drives recurrence
Cathrin Brisken, Giovanna Ambrosini, Georgios Sflomos, Yueyun Zhang, Hazel Margaret Quinn, Kelly Spry Maggs, Patrik Aouad, Fabio De Martino, Céline Marie Victoria Stibolt
More than 70% of human breast cancers (BCs) are estrogen receptor α-positive (ER+). A clinical challenge of ER+ BC is that they can recur decades after initial treatments. Mechanisms governing latent disease remain elusive due to lack of adequate in vivo m ...
2022Tcf1 is essential for initiation of oncogenic Notch1-driven chromatin topology in T-ALL
Freddy Radtke, Ute Koch, Nadine Fournier, Marianne Nkosi, Christelle Dubey, Mateusz Waldemar Antoszewski, Tara Kimberly Sugrue, Giovanni Ciriello
NOTCH1 is a well-established lineage specifier for T cells and among the most frequently mutated genes throughout all subclasses of T cell acute lymphoblastic leukemia (T-ALL). How oncogenic NOTCH1 signaling launches a leukemia-prone chromatin landscape du ...
AMER SOC HEMATOLOGY2022Cell-autonomous inflammation of BRCA1-deficient ovarian cancers drives both tumor-intrinsic immunoreactivity and immune resistance via STING
George Coukos, Julien Dorier, 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 ...
2021A constitutively monomeric UVR8 photoreceptor confers enhanced UV-B photomorphogenesis
Kelvin Ka Ching Lau, Roman Podolec
The plant ultraviolet-B (UV-B) photoreceptor UVR8 plays an important role in UV-B acclimation and survival. UV-B absorption by homodimeric UVR8 induces its monomerization and interaction with the E3 ubiquitin ligase COP1, leading ultimately to gene express ...
NATL ACAD SCIENCES2021Intraductal xenografts show lobular carcinoma cells rely on their own extracellular matrix and LOXL1
Cathrin Brisken, Giovanna Ambrosini, Georgios Sflomos, Ayyakkannu Ayyanan, Laura Battista, Philipp Bucher, Maryse Fiche, Valentina Scabia, Patrik Aouad, Fabio De Martino
Invasive lobular carcinoma (ILC) is the most frequent special histological subtype of breast cancer, typically characterized by loss of E‐cadherin. It has clinical features distinct from other estrogen receptor‐positive (ER+) breast cancers but the molecul ...
2021Centromeres are dismantled by foundational meiotic proteins Spo11 and Rec8
Meiotic processes are potentially dangerous to genome stability and could be disastrous if activated in proliferative cells. Here we show that two key meiosis-defining proteins, the topoisomerase Spo11 (which forms double-strand breaks) and the meiotic coh ...
NATURE RESEARCH2021PRDX1 Counteracts Catastrophic Telomeric Cleavage Events That Are Triggered by DNA Repair Activities Post Oxidative Damage
Telomeres are prone to damage inflicted by reactive oxygen species (ROS). Oxidized telomeric DNA and nucleotide substrates inhibit telomerase, causing telomere shortening. In addition, ROS can induce telomeric single-strand DNA breaks (SSBs). The peroxired ...
2020A novel culture method that sustains ER alpha signaling in human breast cancer tissue microstructures
Cathrin Brisken, Georgios Sflomos
Background Estrogen receptor alpha (ER alpha) signaling is a defining and driving event in most breast cancers; ER alpha is detected in malignant epithelial cells of 75% of all breast cancers (classified as ER-positive breast cancer) and, in these cases, E ...
