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 ...
Targeting cyclooxygenase by indomethacin decelerates progression of acute lymphoblastic leukemia in a xenograft model.
(AMER SOC HEMATOLOGY, 2019-11-12)
Acute lymphoblastic leukemia (ALL) develops in the bone marrow in the vicinity of stromal cells known to promote tumor development and treatment resistance. We previously showed that the cyclooxygenase (COX) inhibitor ...
Targeting the Vulnerability of RB Tumor Suppressor Loss in Triple-Negative Breast Cancer.
(CELL PRESS, 2018-01-30)
Approximately 30% of triple-negative breast cancers (TNBCs) exhibit functional loss of the RB tumor suppressor, suggesting a target for precision intervention. Here, we use drug screens to identify agents specifically ...
The oncolytic virus Delta-24-RGD elicits an antitumor effect in pediatric glioma and DIPG mouse models.
(NATURE PUBLISHING GROUP, 2019-05-28)
Pediatric high-grade glioma (pHGG) and diffuse intrinsic pontine gliomas (DIPGs) are aggressive pediatric brain tumors in desperate need of a curative treatment. Oncolytic virotherapy is emerging as a solid therapeutic ...
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 ...
Evaluation of the Response of Intracranial Xenografts to VEGF Signaling Inhibition Using Multiparametric MRI.
(ELSEVIER SCIENCE INC, 2017-09-01)
Vascular endothelial growth factor A (VEGF-A) is considered one of the most important factors in tumor angiogenesis, and consequently, a number of therapeutics have been developed to inhibit VEGF signaling. Therapeutic ...
Modeling Therapy Resistance in BRCA1/2-Mutant Cancers.
(AMER ASSOC CANCER RESEARCH, 2017-09-01)
Although PARP inhibitors target BRCA1- or BRCA2-mutant tumor cells, drug resistance is a problem. PARP inhibitor resistance is sometimes associated with the presence of secondary or "revertant" mutations in BRCA1 or BRCA2 ...
Recurrent MET fusion genes represent a drug target in pediatric glioblastoma.
(NATURE PUBLISHING GROUP, 2016-11-01)
Pediatric glioblastoma is one of the most common and most deadly brain tumors in childhood. Using an integrative genetic analysis of 53 pediatric glioblastomas and five in vitro model systems, we identified previously ...
