(Submitter supplied) A systematic RNA-seq study comparing the transcriptional response to three independent bulky DNA damage inducing agents: UV, the chemotherapy cisplatin and benzo[a]pyrene, a component of cigarette smoke. It was performed in 2 different cell lines - GM12878 immortalized lymphoblast cell line and A549 lung cancer cell line.

(Submitter supplied) Benzo[a]pyrene (BaP), a polycyclic aromatic hydrocarbon, is the major cause of lung cancer. It forms covalent DNA adducts after metabolic activation and induces mutations. We have developed a method capturing oligonucleotides carrying bulky base adducts, including UV-induced cyclobutane pyrimidine dimers (CPDs) and BaP diol epoxide-deoxyguanosine (BPDE-dG), which are removed from the genome by nucleotide excision repair. more...

(Submitter supplied) Platinum chemotherapies induce damages in DNA that distort the helical structure. In human cells, these adducts are removed primarily by the Nucleotide Excision Repair pathway. In this study, we mapped both cisplatin and oxaliplatin induced damages and their repair at single nucleotide resolution across the human genome.

(Submitter supplied) DNA damage induced by benzo(a)pyrene may lead to the formation of mutations and as a consequence to the development of diseases. However, it is uncertain whether benzo(a)pyrene causes heritable mutations in male germ cells, which would increase health risks in offspring. In a previous study, benzo(a)pyrene induced DNA damage was observed at all stages of spermatogenesis and in testis. In addition, we observed that spermatogonial stem cells and testis rely, at least in part, on nucleotide excision repair for the removal of this damage, because removal was less efficient in Xpc-/- than in wild type mice. more...

(Submitter supplied) Exposure to xenobiotics has repeatedly been associated with adverse health effects. While the majority of reported cases still relates to direct substance effects, there is increasing evidence that microbiome-dependent metabolism of xenobiotic substances likewise has direct adverse effects on the host. This can be due to microbial biotransformation of compounds, interaction between the microbiota and the host’s endogenous detoxification enzymes or altered xenobiotic bioavailability. more...

(Submitter supplied) BACKGROUND: Benzo[a]pyrene (BaP) is a widespread environmental genotoxic carcinogen that damages DNA by forming adducts. This damage along with activation of the aryl hydrocarbon receptor (AHR) induces complex transcriptional responses in cells. To investigate whether human cells are more susceptible to BaP in a particular phase of the cell cycle, synchronised breast carcinoma MCF-7 cells were exposed to BaP. more...

(Submitter supplied) Nucleotide excision repair is a primary DNA repair mechanism that removes bulky DNA adducts such as UV-induced pyrimidine dimers. Correspondingly, genome-wide mapping of nucleotide excision repair with eXcision Repair sequencing (XR-seq), provides comprehensive profiling of DNA damage repair. A number of XR-seq experiments at a variety of conditions for different damage types revealed heterogenous repair in the human genome. more...

(Submitter supplied) We developed a method for genome-wide mapping of DNA excision repair named XR-seq (eXcision Repair-seq). Human nucleotide excision repair generates two incisions surrounding the site of damage, creating a ~30-mer. In XR-seq, this fragment is isolated and subjected to high-throughput sequencing. We used XR-seq to produce stranded, nucleotide-resolution maps of repair of two UV-induced DNA damages in human cells, cyclobutane pyrimidine dimers (CPDs) and (6-4) pyrimidine-pyrimidone photoproducts ((6-4)PPs). more...

(Submitter supplied) Polycyclic aromatic hydrocarbons (PAHs) are abundant organic compounds and are anthropogenically produced by the incomplete combustion of organic matter (e.g. fossil fuels and tobacco smoke). One notable model PAH is benzo[a]pyrene (BaP), which is listed as a Group 1 human carcinogen by the International Agency of Research on Cancer (IARC). Although the mode of action for BaP is well known in higher organisms, limited knowledge is available regarding the consequence of BaP exposure in the model organism Caenorhabditis elegans. more...

(Submitter supplied) Abstract Background: Faithful transcription of DNA is constantly threatened by different endogenous and environmental genotoxic effects. Transcription coupled repair has been described to quickly remove DNA lesions from the transcribed strand of active genes, permitting rapid resumption of blocked transcription. This repair mechanism has been well characterized in the past using individual target genes. more...

(Submitter supplied) Development of a new low density stress response microarray to evaluate biological effects of contaminants in Mytilus sp: laboratory validation. Background: Despite the increasing use of mussels in environmental monitoring, their genome and gene functions remain weakly explored. Recently several cDNA microarrays were proposed in Mytilussp, however partial putatively identified transcripts are provided rendering very difficult the generation of robust transcriptional responses in term of pathwaysidentification. more...

(Submitter supplied) The environmental carcinogen, (±)-anti-benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE), causes bulky-adduct DNA damages, triggers certain signaling pathways, and elicits gene expression changes. Here, we focused on the temporal gene expression changes induced by a low concentration (0.05 µM) BPDE in human amnion epithelial FL cells. Differential gene expression profiles at 1, 10 and 22 h post BPDE treatment were obtained using Affymetrix HG-U133 Plus 2.0 oligonucleotide microarrays. more...
