Testing chemical agents with the cytokinesis-block micronucleus cytome assay.
In order to evaluate the applicability of the cytokinesis-block micronucleus cytome assay in routine mutagenicity testing we investigated with this method different chemicals having different mechanisms of action: non-mutagens, direct-acting basealtering mutagens, direct-acting cross-linking mutagens, clastogens including a radiomimeti...
متن کاملAutomation of the cytokinesis-block micronucleus cytome assay by laser scanning cytometry and its potential application in radiation biodosimetry.
Here we describe the adaptation of laser scanning cytometry (LSC) to measure micronuclei (MN) automatically in lymphocytes. MN frequencies were determined in irradiated human lymphocytes using the cytokinesis-block technique, and the results from LSC were compared with visual scoring results obtained from slides of cells stained using Fast Green and 4',6-diamidino-2-phenylindole (DAPI). This fl...
متن کاملCytokinesis-blocked micronucleus cytome assay biomarkers identify lung cancer cases amongst smokers.
The multi-endpoint cytokinesis-blocked micronucleus assay is used for assessing chromosome aberrations. We have recently reported that this assay is extremely sensitive to genetic damage caused by the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and that the binucleated cells with micronuclei, nucleoplasmic bridges, and nuclear buds in lymphocytes (chromosom...
متن کاملLaboratory intercomparison of the cytokinesis-block micronucleus assay.
The focus of the study is an intercomparison of laboratories' dose-assessment performances using the cytokinesis-block micronucleus (CBMN) assay as a diagnostic triage tool for individual radiation dose assessment. Homogenously X-irradiated (240 kVp, 1 Gy/min) blood samples for establishing calibration data (0.25-5 Gy) as well as blind samples (0.1-6.4 Gy) were sent to the participants. The CBM...
متن کاملChronic alcohol exposure induces genome damage measured using the cytokinesis-block micronucleus cytome assay and aneuploidy in human B lymphoblastoid cell lines.
Excessive alcohol consumption is associated with an increased risk of a variety of cancers. The specific association between alcohol consumption and increased risk of breast cancer has been a consistent finding in numerous studies to date; however, the biological mechanism remains unknown. One possibility is that alcohol induces chromosome instability and aneuploidy events commonly seen in canc...
