A Biobank of Breast Cancer Explants with Preserved Intra-tumor Heterogeneity to Screen Anticancer Compounds.
(CELL PRESS, 2016-09-22)
The inter- and intra-tumor heterogeneity of breast cancer needs to be adequately captured in pre-clinical models. We have created a large collection of breast cancer patient-derived tumor xenografts (PDTXs), in which the ...
Shieldin complex promotes DNA end-joining and counters homologous recombination in BRCA1-null cells.
(NATURE PUBLISHING GROUP, 2018-08-01)
BRCA1 deficiencies cause breast, ovarian, prostate and other cancers, and render tumours hypersensitive to poly(ADP-ribose) polymerase (PARP) inhibitors. To understand the resistance mechanisms, we conducted whole-genome ...
ARID1A influences HDAC1/BRD4 activity, intrinsic proliferative capacity and breast cancer treatment response.
(NATURE PORTFOLIO, 2020-02-01)
Using genome-wide clustered regularly interspaced short palindromic repeats (CRISPR) screens to understand endocrine drug resistance, we discovered ARID1A and other SWI/SNF complex components as the factors most critically ...
The Lineage Determining Factor GRHL2 Collaborates with FOXA1 to Establish a Targetable Pathway in Endocrine Therapy-Resistant Breast Cancer.
(CELL PRESS, 2019-10-22)
Notwithstanding the positive clinical impact of endocrine therapies in estrogen receptor-alpha (ERα)-positive breast cancer, de novo and acquired resistance limits the therapeutic lifespan of existing drugs. Taking the ...
Validation of the OncoMasTR Risk Score in Estrogen Receptor-Positive/HER2-Negative Patients: A TransATAC study.
(AMER ASSOC CANCER RESEARCH, 2020-02-01)
PURPOSE: To test the validity of OncoMasTR Molecular Score (OMm), OMclin1, and OncoMasTR Risk Score (OMclin2) prognostic scores for prediction of distant recurrence (DR) in estrogen receptor (ER)-positive/HER2-negative ...
Inactivating NF1 Mutations Are Enriched in Advanced Breast Cancer and Contribute to Endocrine Therapy Resistance.
(AMER ASSOC CANCER RESEARCH, 2020-02-01)
PURPOSE: Advanced breast cancer (ABC) has not been subjected to the same degree of molecular scrutiny as early primary cancer. Breast cancer evolves with time and under the selective pressure of treatment, with the potential ...
ABC-transporter upregulation mediates resistance to the CDK7 inhibitors THZ1 and ICEC0942.
(NATURE PUBLISHING GROUP, 2020-01-01)
The CDK7 inhibitors (CDK7i) ICEC0942 and THZ1, are promising new cancer therapeutics. Resistance to targeted drugs frequently compromises cancer treatment. We sought to identify mechanisms by which cancer cells may become ...
Landscapes of cellular phenotypic diversity in breast cancer xenografts and their impact on drug response.
(NATURE PORTFOLIO, 2021-03-31)
The heterogeneity of breast cancer plays a major role in drug response and resistance and has been extensively characterized at the genomic level. Here, a single-cell breast cancer mass cytometry (BCMC) panel is optimized ...
Mapping the breast cancer metastatic cascade onto ctDNA using genetic and epigenetic clonal tracking.
(NATURE PORTFOLIO, 2020-03-27)
Circulating tumour DNA (ctDNA) allows tracking of the evolution of human cancers at high resolution, overcoming many limitations of tissue biopsies. However, exploiting ctDNA to determine how a patient's cancer is evolving ...
Abiraterone shows alternate activity in models of endocrine resistant and sensitive disease.
(SPRINGERNATURE, 2018-08-01)
BACKGROUND: Resistance to endocrine therapy remains a major clinical problem in the treatment of oestrogen-receptor positive (ER+) breast cancer. Studies show androgen-receptor (AR) remains present in 80-90% of metastatic ...
