An ERCC4 regulatory variant predicts grade-3 or -4 toxicities in patients with advanced non-small cell lung cancer treated by platinum-based therapy.
(International journal of cancer, 2018-03)Platinum-based chemotherapy (PBC) in combination with the 3rd generation drugs is the first-line treatment for patients with advanced non-small cell lung cancer (NSCLC); however, the efficacy is severely hampered by grade ... -
Association between DNA damage response and repair genes and risk of invasive serous ovarian cancer.
(PLoS One, 2010-04-08)BACKGROUND: We analyzed the association between 53 genes related to DNA repair and p53-mediated damage response and serous ovarian cancer risk using case-control data from the North Carolina Ovarian Cancer Study (NCOCS), ... -
CometChip enables parallel analysis of multiple DNA repair activities.
(DNA repair, 2021-10)DNA damage can be cytotoxic and mutagenic, and it is directly linked to aging, cancer, and other diseases. To counteract the deleterious effects of DNA damage, cells have evolved highly conserved DNA repair pathways. Many ... -
Correlation between base-excision repair gene polymorphisms and levels of in-vitro BPDE-induced DNA adducts in cultured peripheral blood lymphocytes.
(PloS one, 2012-01)In vitro benzo[a]pyrene diol epoxide (BPDE)-induced DNA adducts in cultured peripheral lymphocytes have been shown to be a phenotypic biomarker of individual's DNA repair phenotype that is associated with cancer risk. In ... -
Genetic variants of DNA repair genes predict the survival of patients with esophageal squamous cell cancer receiving platinum-based adjuvant chemotherapy.
(Journal of translational medicine, 2016-05-31)Adjuvant chemotherapy in patients with resected esophageal squamous cell cancer (ESCC) remains controversial for its uncertain role in improving overall survival (OS). Nucleotide excision repair (NER) removes DNA-adducts ... -
Human longevity and variation in GH/IGF-1/insulin signaling, DNA damage signaling and repair and pro/antioxidant pathway genes: cross sectional and longitudinal studies.
(Exp Gerontol, 2012-05)Here we explore association with human longevity of common genetic variation in three major candidate pathways: GH/IGF-1/insulin signaling, DNA damage signaling and repair and pro/antioxidants by investigating 1273 tagging ... -
Insights into Watson-Crick/Hoogsteen breathing dynamics and damage repair from the solution structure and dynamic ensemble of DNA duplexes containing m1A.
(Nucleic acids research, 2017-05)In the canonical DNA double helix, Watson-Crick (WC) base pairs (bps) exist in dynamic equilibrium with sparsely populated (∼0.02-0.4%) and short-lived (lifetimes ∼0.2-2.5 ms) Hoogsteen (HG) bps. To gain insights into transient ... -
Mitochondrial DNA damage induced autophagy, cell death, and disease.
(Front Biosci (Landmark Ed), 2016-01-01)Mammalian mitochondria contain multiple small genomes. While these organelles have efficient base excision removal of oxidative DNA lesions and alkylation damage, many DNA repair systems that work on nuclear DNA damage are ... -
Mitotic DNA Damage Responses in Drosophila Polyploid Rectal Papillar Cells
(2021)Mitosis involves the faithful segregation of two identical copies of chromosomes into two daughter cells. This process is highly regulated to maintain genome integrity, as mis-segregation of partial or whole chromosomes ... -
Nucleolar organization, ribosomal DNA array stability, and acrocentric chromosome integrity are linked to telomere function.
(PLoS One, 2014)The short arms of the ten acrocentric human chromosomes share several repetitive DNAs, including ribosomal RNA genes (rDNA). The rDNA arrays correspond to nucleolar organizing regions that coalesce each cell cycle to form ... -
Polymorphisms in ERCC1 and XPF genes and risk of gastric cancer in an eastern Chinese population.
(PloS one, 2012-01)BACKGROUND: Inherited functional single nucleotide polymorphisms (SNPs) in DNA repair genes may alter DNA repair capacity and thus contribute to cancer risk. METHODS: Three ERCC1 functional SNPs (rs2298881C>A, rs3212986C>A ... -
Polymorphisms in nucleotide excision repair genes and risk of primary prostate cancer in Chinese Han populations.
(Oncotarget, 2017-04)Genetic variants of nucleotide excision repair (NER) genes have been extensively investigated for their roles in the development of prostate cancer (PCa); however, the published results have been inconsistent. In a hospital-based ... -
Polymorphisms of nucleotide excision repair genes predict melanoma survival.
(The Journal of investigative dermatology, 2013-07)Melanoma is the most highly malignant skin cancer, and nucleotide excision repair (NER) is involved in melanoma susceptibility. In this analysis of 1,042 melanoma patients, we evaluated whether genetic variants of NER genes ... -
Potentially functional polymorphisms in the ERCC2 gene and risk of esophageal squamous cell carcinoma in Chinese populations.
(Scientific reports, 2014-01)ERCC2 is indispensable for nucleotide excision repair pathway, and its functional polymorphisms may be associated with cancer risk. In a large case-control study of 1126 esophageal squamous cell carcinomas (ESCC) patients ... -
Sequence variations in DNA repair gene XPC is associated with lung cancer risk in a Chinese population: a case-control study.
(BMC cancer, 2007-01)BACKGROUND: The nucleotide excision repair (NER) protein, xeroderma pigmentosum C (XPC), participates in recognizing DNA lesions and initiating DNA repair in response to DNA damage. Because mutations in XPC cause a high ... -
Single-cell microarray enables high-throughput evaluation of DNA double-strand breaks and DNA repair inhibitors.
(Cell Cycle, 2013-03-15)A key modality of non-surgical cancer management is DNA damaging therapy that causes DNA double-strand breaks that are preferentially toxic to rapidly dividing cancer cells. Double-strand break repair capacity is recognized ... -
The bromodomain protein Brd4 insulates chromatin from DNA damage signalling.
(Nature, 2013-06-13)DNA damage activates a signalling network that blocks cell-cycle progression, recruits DNA repair factors and/or triggers senescence or programmed cell death. Alterations in chromatin structure are implicated in the initiation ... -
Topoisomerase 1 (Top1)-associated Genome Instability in Yeast: Effects of Persistent Cleavage Complexes or Increased Top1 Levels
(2016)Topoisomerase 1 (Top1), a Type IB topoisomerase, functions to relieve transcription- and replication-associated torsional stress in DNA. Top1 cleaves one strand of DNA, covalently associates with the 3’ end of the nick to ... -
