Immune status is prognostic for poor survival in colorectal cancer patients and is associated with tumour hypoxia.
(SPRINGERNATURE, 2020-10-13)
BACKGROUND: Immunohistochemical quantification of the immune response is prognostic for colorectal cancer (CRC). Here, we evaluate the suitability of alternative immune classifiers on prognosis and assess whether they ...
A new method for the high-precision assessment of tumor changes in response to treatment.
(OXFORD UNIV PRESS, 2018-08-01)
MOTIVATION: Imaging demonstrates that preclinical and human tumors are heterogeneous, i.e. a single tumor can exhibit multiple regions that behave differently during both development and also in response to treatment. The ...
Impact of Variable RNA-Sequencing Depth on Gene Expression Signatures and Target Compound Robustness: Case Study Examining Brain Tumor (Glioma) Disease Progression.
(LIPPINCOTT WILLIAMS & WILKINS, 2018-09-13)
PURPOSE: Gene expression profiling can uncover biologic mechanisms underlying disease and is important in drug development. RNA sequencing (RNA-seq) is routinely used to assess gene expression, but costs remain high. Sample ...
Critical Appraisal of Programmed Death Ligand 1 Reflex Diagnostic Testing: Current Standards and Future Opportunities.
(ELSEVIER SCIENCE INC, 2019-01-01)
INTRODUCTION: Patient suitability to anti-programmed death ligand 1 (PD-L1) immune checkpoint inhibition is key to the treatment of NSCLC. We present, applied to PD-L1 testing: a comprehensive cross-validation of two ...
NUQA: Estimating Cancer Spatial and Temporal Heterogeneity and Evolution through Alignment-Free Methods.
(OXFORD UNIV PRESS, 2019-12-01)
Longitudinal next-generation sequencing of cancer patient samples has enhanced our understanding of the evolution and progression of various cancers. As a result, and due to our increasing knowledge of heterogeneity, such ...
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 ...
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 ...
