Project description:To identify APA changes in cancer cells in response to DNA damage, PAPERCLIP was performed on HeLa and LN229 cells with/without Doxorubicin treatment.
Project description:Chemotherapy Treatment alone with DNA damaging drugs might be as effective as chemotherapy combined with surgery in colorectal cancer (CRC) avoiding surgery complications.
Project description:We used microarrays to identify differentially expressed genes after DNA-damaging agent bleomycin (BLM) and/or immune inducer 2, 6-dichloroisonicotinic acid (INA) treatment. We focused on those genes that were synergistically induced by co-treatment (BLM+INA). Arabidopsis seedlings were treated with 4 μg/ml BLM and/or low INA (10 μM). There are 4 treatments: control (CK), INA, BLM and BLM+INA. Each treatments have three biological replicates. There are 12 samples in total.
Project description:We have investigated whether gene expression signatures can be used to predict inter-individual responses to DNA damaging agents We used microarrays to detail inter-individual variation in gene expression across a healthy population under basal and damage induced conditions Keywords: dose (MNNG)
Project description:GM0637 cell were treated with or without DNA damaging agent neocarzinostatin (NCS), and cells were harvested after 4 hours and 8 hours for the microarray analyses of whole-genome long noncoding RNAs.
Project description:GM0637 cell were treated with or without DNA damaging agent neocarzinostatin (NCS), and cells were harvested after 4 hours and 8 hours for the microarray analyses of whole-genome long noncoding RNAs. To examine how long noncoding RNAs are regulated in the DNA damage response, we assessed the genome-wide long noncoding RNA expression in GM0637 cells treated with or without DNA damage
Project description:Genome-wide DNA methylation profiling in cultured human Schelmm's Canal endothelial cells (SC) and trabecular meshwork (TM) cells derived from post-mortem eyes with or without glaucoma. Our study aimed to identify glaucoma-associated genes that were affected by DNA methylation.
Project description:We have looked at the transcriptional response of well characterised Synechococcus open ocean (WH8102) and coastal (CC9311) isolates to two DNA damaging agents, mitomycin C and ethidium bromide, using whole genome expression microarrays. The coastal strain, which was able to grow on higher concentrations of both chemicals, showed differential regulation of a larger proportion of its genome following ‘toxic shock’ treatment with each agent. Many of the orthologous genes in these strains, including those encoding sensor kinases, showed different transcriptional responses, with the CC9311 genes more likely to show significant changes for each tested treatment. While the overall response of each strain was considerably different, there were distinct transcriptional responses common to both strains observed for each DNA damaging agent, linked to the mode of action of each chemical. In both CC9311 and WH8102 there was evidence of SOS response induction under mitomycin C treatment, with genes encoding recA, the lexA repressor and umuC significantly upregulated in this experiment but not under ethidium bromide treatment. Conversely, ethidium bromide treatment tended to result in upregulation of the DNA-directed RNA polymerase genes, not observed following mitomycin C treatment. Interestingly, a large number of genes residing on putative genomic island regions of each genome also showed significant upregulation under one or both chemical treatments.
