Diverse AR Gene Rearrangements Mediate Resistance to Androgen Receptor Inhibitors in Metastatic Prostate Cancer.
(AMER ASSOC CANCER RESEARCH, 2020-04-15)PURPOSE: Prostate cancer is the second leading cause of male cancer deaths. Castration-resistant prostate cancer (CRPC) is a lethal stage of the disease that emerges when endocrine therapies are no longer effective at ... -
Diverse BRCA1 and BRCA2 Reversion Mutations in Circulating Cell-Free DNA of Therapy-Resistant Breast or Ovarian Cancer.
(AMER ASSOC CANCER RESEARCH, 2017-11-01)Purpose: Resistance to platinum-based chemotherapy or PARP inhibition in germline BRCA1 or BRCA2 mutation carriers may occur through somatic reversion mutations or intragenic deletions that restore BRCA1 or BRCA2 function. ... -
DNA Copy Number Aberrations, and Human Papillomavirus Status in Penile Carcinoma. Clinico-Pathological Correlations and Potential Driver Genes
(2016-01-01)Penile squamous cell carcinoma is a rare disease, in which somatic genetic aberrations have yet to be characterized. We hypothesized that gene copy aberrations might correlate with human papillomavirus status and ... -
DNA Damage Activates a Spatially Distinct Late Cytoplasmic Cell-Cycle Checkpoint Network Controlled by MK2-Mediated RNA Stabilization
(CELL PRESS, 2010-10-08)Following genotoxic stress, cells activate a complex kinase-based signaling network to arrest the cell cycle and initiate DNA repair. p53-defective tumor cells rewire their checkpoint response and become dependent on the ... -
DNA damage during S-phase mediates the proliferation-quiescence decision in the subsequent G1 via p21 expression.
(NATURE PUBLISHING GROUP, 2017-03-20)Following DNA damage caused by exogenous sources, such as ionizing radiation, the tumour suppressor p53 mediates cell cycle arrest via expression of the CDK inhibitor, p21. However, the role of p21 in maintaining genomic ... -
DNA Damage, Repair, and Cancer Metabolism.
(FRONTIERS MEDIA SA, 2018-02-05)Although there has been a renewed interest in the field of cancer metabolism in the last decade, the link between metabolism and DNA damage/DNA repair in cancer has yet to be appreciably explored. In this review, we examine ... -
DNA methylation age in paired tumor and adjacent normal breast tissue in Chinese women with breast cancer.
(BMC, 2023-03-30)BACKGROUND: Few studies have examined epigenetic age acceleration (AA), the difference between DNA methylation (DNAm) predicted age and chronological age, in relation to somatic genomic features in paired cancer and normal ... -
DNA methylation of shelf, shore and open sea CpG positions distinguish high microsatellite instability from low or stable microsatellite status colon cancer stem cells.
(FUTURE MEDICINE LTD, 2019-05-01)Aim: To investigate the genome-wide methylation of genetically characterized colorectal cancer stem cell (CR-CSC) lines. Materials & methods: Eight CR-CSC lines were isolated from primary colorectal cancer (CRC) tissues, ... -
DNA methylation of the long intergenic noncoding RNA 299 gene in triple-negative breast cancer: results from a prospective study.
(NATURE PORTFOLIO, 2020-07-16)Triple-negative breast cancer (TNBC) is an aggressive breast cancer subtype associated with a high rate of recurrence and poor prognosis. Recently we identified a hypermethylation in the long noncoding RNA 299 (LINC00299) ... -
DNA methylation patterns identify subgroups of pancreatic neuroendocrine tumors with clinical association.
(2021-02-03)Here we report the DNA methylation profile of 84 sporadic pancreatic neuroendocrine tumors (PanNETs) with associated clinical and genomic information. We identified three subgroups of PanNETs, termed T1, T2 and T3, with ... -
DNA methylation-based classification of central nervous system tumours.
(NATURE PORTFOLIO, 2018-03-22)Accurate pathological diagnosis is crucial for optimal management of patients with cancer. For the approximately 100 known tumour types of the central nervous system, standardization of the diagnostic process has been shown ... -
DNA methylation-based classification of glioneuronal tumours synergises with histology and radiology to refine accurate molecular stratification.
(WILEY, 2023-04-01)AIMS: Glioneuronal tumours (GNTs) are poorly distinguished by their histology and lack robust diagnostic indicators. Previously, we showed that common GNTs comprise two molecularly distinct groups, correlating poorly with ... -
DNA origami-based single-molecule force spectroscopy elucidates RNA Polymerase III pre-initiation complex stability.
(NATURE PUBLISHING GROUP, 2020-06-05)The TATA-binding protein (TBP) and a transcription factor (TF) IIB-like factor are important constituents of all eukaryotic initiation complexes. The reason for the emergence and strict requirement of the additional ... -
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 ... -
DNA Repair in Prostate Cancer: Biology and Clinical Implications.
(ELSEVIER SCIENCE BV, 2017-03-01)CONTEXT: For more precise, personalized care in prostate cancer (PC), a new classification based on molecular features relevant for prognostication and treatment stratification is needed. Genomic aberrations in the DNA ... -
DNA replication stress mediates APOBEC3 family mutagenesis in breast cancer.
(BMC, 2016-09-15)BACKGROUND: The APOBEC3 family of cytidine deaminases mutate the cancer genome in a range of cancer types. Although many studies have documented the downstream effects of APOBEC3 activity through next-generation sequencing, ... -
DNA-PK controls Apollo's access to leading-end telomeres.
