Genetic instability in bladder cancer assessed by the comet assay.
BACKGROUND Latent genetic instability has been associated with an increased risk for several cancers. We used the comet assay (single-cell gel electrophoresis) to assess whether genetic instability, as reflected by susceptibility to DNA damage, was associated with the risk of bladder cancer in a case-control study. METHODS We used the comet assay to measure baseline and benzo[a]pyrene diol ep...
متن کاملImprovement of single-cell gel electrophoresis (SCGE) alkaline comet assay
Although the single-cell gel electrophoresis (SCGE) alkaline comet assay can detect DNA damage quickly and with high sensitivity, it does not work well for cryopreserved sperm of some marine teleosts. Using large yellow croaker Pseudosciaena crocea sperm that were cryopreserved in increasing concentrations (5 to 30%) of DMSO, we made modifications to the classic SCGE method that included using ...
متن کاملRadiosensitivity and Repair Kinetics of Gamma-Irradiated Leukocytes from Sporadic Prostate Cancer Patients and Healthy Individuals Assessed by Alkaline Comet Assay
Background: Impaired DNA repair mechanism is one of the main causes of tumor genesis. Study of intrinsic radiosensitivity of cancer patients in a non-target tissue (e.g. peripheral blood) might show the extent of DNA repair deficiency of cells in affected individuals and might be used a predictor of cancer predisposition. Methods: Initial radiation-induced DNA damage (ratio of Tail DNA/Head DN...
متن کاملEvaluation of DNA damage in radiotherapy-treated cancer patients using the alkaline comet assay.
The aim of this study was to evaluate primary DNA damage and the dynamics of the repair of radiotherapy-induced DNA lesions in non-target cells of cancer patients. This study included patients diagnosed with different solid tumors who received radiotherapy. The levels of DNA damage were evaluated using the alkaline comet assay on peripheral blood leukocytes. Altogether four blood samples per pa...
متن کاملRecommendations for conducting the in vivo alkaline Comet assay. 4th International Comet Assay Workshop.
The in vivo alkaline single cell gel electrophoresis assay, hereafter the Comet assay, can be used to investigate the genotoxicity of industrial chemicals, biocides, agrochemicals and pharmaceuticals. The major advantages of this assay include the relative ease of application to any tissue of interest, the detection of multiple classes of DNA damage and the generation of data at the level of th...
