Targeting DNA Repair in Cancer: Beyond PARP Inhibitors.
(2017-01)
Germline aberrations in critical DNA-repair and DNA damage-response (DDR) genes cause cancer predisposition, whereas various tumors harbor somatic mutations causing defective DDR/DNA repair. The concept of synthetic lethality ...
DNA-Repair Defects and Olaparib in Metastatic Prostate Cancer.
(MASSACHUSETTS MEDICAL SOC, 2015-10-29)
BACKGROUND: Prostate cancer is a heterogeneous disease, but current treatments are not based on molecular stratification. We hypothesized that metastatic, castration-resistant prostate cancers with DNA-repair defects would ...
Distinct roles of BRCA2 in replication fork protection in response to hydroxyurea and DNA interstrand cross-links.
(COLD SPRING HARBOR LAB PRESS, PUBLICATIONS DEPT, 2020-06-01)
DNA interstrand cross-links (ICLs) are a form of DNA damage that requires the interplay of a number of repair proteins including those of the Fanconi anemia (FA) and the homologous recombination (HR) pathways. Pathogenic ...
Mutant IDH1 Downregulates ATM and Alters DNA Repair and Sensitivity to DNA Damage Independent of TET2.
(CELL PRESS, 2016-08-08)
Mutations in the isocitrate dehydrogenase-1 gene (IDH1) are common drivers of acute myeloid leukemia (AML) but their mechanism is not fully understood. It is thought that IDH1 mutants act by inhibiting TET2 to alter DNA ...
Chemosensitivity profiling of osteosarcoma tumour cell lines identifies a model of BRCAness.
(NATURE PORTFOLIO, 2018-07-13)
Osteosarcoma (OS) is an aggressive sarcoma, where novel treatment approaches are required. Genomic studies suggest that a subset of OS, including OS tumour cell lines (TCLs), exhibit genomic loss of heterozygosity (LOH) ...
