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 ...
MDC1 Interacts with TOPBP1 to Maintain Chromosomal Stability during Mitosis.
(CELL PRESS, 2019-05-02)
In mitosis, cells inactivate DNA double-strand break (DSB) repair pathways to preserve genome stability. However, some early signaling events still occur, such as recruitment of the scaffold protein MDC1 to phosphorylated ...
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 ...
Chlorambucil targets BRCA1/2-deficient tumours and counteracts PARP inhibitor resistance.
(WILEY, 2019-07-01)
Due to compromised homologous recombination (HR) repair, BRCA1- and BRCA2-mutated tumours accumulate DNA damage and genomic rearrangements conducive of tumour progression. To identify drugs that target specifically ...
BRCA1 and BRCA2 tumor suppressors protect against endogenous acetaldehyde toxicity.
(WILEY, 2017-10-01)
Maintenance of genome integrity requires the functional interplay between Fanconi anemia (FA) and homologous recombination (HR) repair pathways. Endogenous acetaldehyde, a product of cellular metabolism, is a potent source ...
Patient-derived tumour xenografts for breast cancer drug discovery.
(BIOSCIENTIFICA LTD, 2016-12-01)
Despite remarkable advances in our understanding of the drivers of human malignancies, new targeted therapies often fail to show sufficient efficacy in clinical trials. Indeed, the cost of bringing a new agent to market ...
LUBAC determines chemotherapy resistance in squamous cell lung cancer.
(ROCKEFELLER UNIV PRESS, 2019-02-04)
Lung squamous cell carcinoma (LSCC) and adenocarcinoma (LADC) are the most common lung cancer subtypes. Molecular targeted treatments have improved LADC patient survival but are largely ineffective in LSCC. The tumor ...
Immune activation by DNA damage predicts response to chemotherapy and survival in oesophageal adenocarcinoma.
(BMJ PUBLISHING GROUP, 2019-11-01)
OBJECTIVE: Current strategies to guide selection of neoadjuvant therapy in oesophageal adenocarcinoma (OAC) are inadequate. We assessed the ability of a DNA damage immune response (DDIR) assay to predict response following ...
A Machine Learning Platform to Optimize the Translation of Personalized Network Models to the Clinic.
(AMER SOC CLINICAL ONCOLOGY, 2019-04-17)
PURPOSE: Dynamic network models predict clinical prognosis and inform therapeutic intervention by elucidating disease-driven aberrations at the systems level. However, the personalization of model predictions requires the ...
Recommendations for determining HPV status in patients with oropharyngeal cancers under TNM8 guidelines: a two-tier approach.
(SPRINGERNATURE, 2019-04-16)
BACKGROUND: TNM8 staging for oropharyngeal squamous cell carcinomas (OPSCC) surrogates p16 immunohistochemistry for HPV testing. Patients with p16+ OPSCC may lack HPV aetiology. Here, we evaluate the suitability of TNM8 ...
