Evaluation of CDK12 Protein Expression as a Potential Novel Biomarker for DNA Damage Response-Targeted Therapies in Breast Cancer.
(AMER ASSOC CANCER RESEARCH, 2018-01-01)
Disruption of Cyclin-Dependent Kinase 12 (CDK12) is known to lead to defects in DNA repair and sensitivity to platinum salts and PARP1/2 inhibitors. However, CDK12 has also been proposed as an oncogene in breast cancer. ...
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 ...
DNA repair deficiency sensitizes lung cancer cells to NAD+ biosynthesis blockade.
(AMER SOC CLINICAL INVESTIGATION INC, 2018-04-02)
Synthetic lethality is an efficient mechanism-based approach to selectively target DNA repair defects. Excision repair cross-complementation group 1 (ERCC1) deficiency is frequently found in non-small-cell lung cancer ...
PARP inhibitors and breast cancer: highlights and hang-ups
(TAYLOR & FRANCIS LTD, 2018-01-01)
Advanced Prostate Cancer with ATM Loss: PARP and ATR Inhibitors.
(ELSEVIER, 2020-11-08)
BACKGROUND: Deleterious ATM alterations are found in metastatic prostate cancer (PC); PARP inhibition has antitumour activity against this subset, but only some ATM loss PCs respond. OBJECTIVE: To characterise ATM-deficient ...
A Machine-Learning Tool Concurrently Models Single Omics and Phenome Data for Functional Subtyping and Personalized Cancer Medicine.
(MDPI, 2020-09-30)
One of the major challenges in defining clinically-relevant and less heterogeneous tumor subtypes is assigning biological and/or clinical interpretations to etiological (intrinsic) subtypes. Conventional clustering/subtyping ...
Defective ALC1 nucleosome remodeling confers PARPi sensitization and synthetic lethality with HRD.
(CELL PRESS, 2021-02-18)
Chromatin is a barrier to efficient DNA repair, as it hinders access and processing of certain DNA lesions. ALC1/CHD1L is a nucleosome-remodeling enzyme that responds to DNA damage, but its precise function in DNA repair ...
Chemotherapy-induced senescent cancer cells engulf other cells to enhance their survival.
(ROCKEFELLER UNIV PRESS, 2019-11-04)
In chemotherapy-treated breast cancer, wild-type p53 preferentially induces senescence over apoptosis, resulting in a persisting cell population constituting residual disease that drives relapse and poor patient survival ...
Clonal diversity of MYC amplification evaluated by fluorescent in situ hybridisation and digital droplet polymerase chain reaction in oesophagogastric cancer: Results from a prospective clinical trial screening programme.
(ELSEVIER SCI LTD, 2019-11-01)
INTRODUCTION: The MYC proto-oncogene is among the most commonly dysregulated genes in human cancers. We report screening data from the iMYC trial, an ongoing phase II study assessing ibrutinib monotherapy in advanced ...
Longitudinal analysis of a secondary BRCA2 mutation using digital droplet PCR.
(WILEY, 2019-11-20)
Development of resistance to platinum and poly(ADP-ribose) polymerase inhibitors via secondary BRCA gene mutations that restore functional homologous recombination has been observed in a number of cancer types. Here we ...
