BRCA1(185delAG) tumors may acquire therapy resistance through expression of RING-less BRCA1 [PDF]

open access: yes, 2016
Heterozygous germline mutations in breast cancer 1 (BRCA1) strongly predispose women to breast cancer. BRCA1 plays an important role in DNA double-strand break (DSB) repair via homologous recombination (HR), which is important for tumor suppression ...

Prevalence of Helicobacter pylori Exposure and Risk Factors Among BRCA1 and BRCA2 Carriers

open access: yesInternational Journal of Cancer, EarlyView.
BRCA1 and BRCA2 pathogenic germline variant (PGV) carriers may be at increased risk of gastric cancer (GC), especially in the case of prior or active Helicobacter pylori (Hp) infection. The extent to which Hp influences BRCA1 and BRCA2‐associated GC remains uncertain. Here, the authors evaluated plasma samples from a U.S. cohort of BRCA1, BRCA2, PALB2,

Association of Risk-Reducing Surgery in BRCA1 or BRCA2 Mutation Carriers with Cancer Risk and Mortality

open access: yesJournal of the American Medical Association (JAMA), 2010
Context Risk-reducing mastectomy (RRM) and salpingo-oophorectomy (RRSO) are widely used by carriers of BRCA1 or BRCA2 mutations to reduce their risks of breast and ovarian cancer. Objectives To estimate risk and mortality reduction stratified by mutation

Cancer Incidence in BRCA1 Mutation Carriers

open access: yes, 2002
Background: Germline BRCA1 mutations confer a substantial lifetime risk of breast and ovarian cancer, but whether cancer at other sites is increased is less clear.

Pancreatic Cancer Early Detection Biomarkers for High‐Risk Individuals: Insights From the PRECEDE Consortium

open access: yesInternational Journal of Cancer, EarlyView.
ABSTRACT Pancreatic ductal adenocarcinoma (PDAC) remains one of the deadliest cancers due to its asymptomatic progression, late‐stage diagnosis, and treatment resistance. Efforts in early detection have centered on identifying imaging features and liquid biopsy biomarkers capable of detecting PDAC and its high‐grade precursors before clinical symptoms ...

Role of the Nrf2/ARE Pathway in the mtDNA Reparation

open access: yesFrontiers in Bioscience-Landmark
Mitochondrial DNA (mtDNA) is located in the mitochondrial matrix, in close proximity to major sources of reactive oxygen species (ROS) in the cell. This makes mtDNA one of the most susceptible components to damage in the cell.

Relationship between DNA damage response and telomere maintenance [PDF]

open access: yes, 2012
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Telomeres are regions of repetitive DNA bound with a set of specialized proteins required to protect chromosomes from fusing with each other and from ...

Clinical Implementation and Oncological Relevance of Molecular Profiling in Brain Metastases Patients—A Multicenter Retrospective Cohort Study

open access: yesInternational Journal of Cancer, EarlyView.
While current guidelines recommend the analysis of established cancer driver genes in brain metastases, little is known about its real‐life implementation. This multicenter study revealed an upward trend in the profiling rates of surgically treated brain metastases over the past decade, with up to 60% of brain metastases samples undergoing analysis ...
