In the exposed group, 52 people had a higher frequency of cells with MN per cells than their counterparts in the control group. Because MN are expressed in cells that have completed nuclear kicronucleus, they can be ideally scored during the binucleated stage of the cell cycle [ 7 ].

Cytokinexis health status assessed by a cytokinesis-block micronucleus cytome assay in a healthy middle-aged Korean population.

The Kemerovo study prompted further cytogenetic analysis of the population residing in this region [ 2 ]. Each genetic alteration or mutation, whether an initiating or a progression-associated event, can cause gross chromosomal changes and can therefore be detected cytogenetically [ 314 ].

The CBMN is a convenient and effective method for assessing the genome damage caused by genotoxicants, and cytominesis can be used in ecological and genetic studies as a biological mivronucleus test.

Read Article at publisher’s site. In addition, information regarding other cellular events such as mitotic rate and cell death by apoptosis and necrosis can be simultaneously obtained from the same slides [ 6 ].

Cells were observed in the preparations to have varying numbers of nuclei. Next, the suspension was gently transferred to a dry, cold glass slide using a pipette. This increase might have been caused by a compensatory mechanism to promote a more rapid renewal of the proliferative pool under the genotoxic effects of radon.

A method of mapping cytogenetic effects in a population within a large industrial region has been developed and used by the staff of the Department of Genetics, Kemerovo State University.


Cytokinesis-block micronucleus assay evolves into a “cytome” cytokinseis of chromosomal instability, mitotic dysfunction and cell death. Neoplasms Search for additional papers on this topic.

MN were observed in cells that had progressed through more than one mitotic event. Druzhinin; The application of the cytokinesis-block micronucleus assay on peripheral blood lymphocytes for the assessment of genome damage micronucleux long-term residents of areas with high radon concentration, Journal of Radiation ResearchVolume 55, Issue 1, 1 JanuaryPages 61—66, https: This paper has been referenced on Twitter 7 times over the past 90 days.

BioTechniques [01 Dec57 6: General conditions and overall conclusions of the study. In addition to using methods of dosimetry to evaluate the risk of harmful radiation effects, the cyyome of such a risk should be evaluated by a biological marker.

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-diamidinophenylindole DAPI.

In this study we used the following formula: Detailed descriptions of these are presented in Table 2. From This Paper Figures, tables, and topics from this paper.

In the exposed group, radon was found to cause significant cytogenetic alterations. The high-throughput nature of LSC can provide unique advantages in future DNA damage diagnostics in experimental and epidemiological studies.

With respect to previous studies on radiation-induced genotoxicity, children are a poorly studied group, as evidenced by the few publications in this area. How do in vivo mammalian assays compare to in vitro assays in their ability to detect mutagens?

This result can be explained by the small number of cells with bridges and dicentric chromosomes. In addition to living in the same area, all members in this study had similar diets and accommodation. Biological Markers Excretory function Nutrigenomics. Citations Publications citing this paper. Significant difference between groups: Schmid [ 15 ] and Heddle [ 9 ] independently proposed an alternative and simpler approach for assessing chromosome damage in vivo and that was measuring micronuclei MNalso known as Howell—Jolly bodies.


Occasionally, nucleoplasmic bridges NPBs are observed between the nuclei in a binucleated cell. The absence of significant chemical pollutants in this region, along with a prevalence of dicentric and ring chromosomes 0. Related articles in Web of Science Google Scholar. This approach provides the most detailed analysis, but the complexity and laboriousness of enumerating the aberrations in metaphase spreads, confounded by an artefactual loss of chromosomes from metaphase preparations has prompted the development of a simpler system for measuring chromosome damage [ 15 ].

This area lacks chemical contaminants and has low radon levels This procedure was repeated several times until the pellet appeared clean and the cell suspension was clear. Receive exclusive offers and updates from Oxford Academic.

However, it is important to note that current models estimating the risk of radiation-related hazards are based upon analysis of ctyokinesis collected from irradiated miners. Characteristics of this group are presented in Table 3.

Based on an assessment of an adaptive response, three cultures were created from each sample. The cytokinesis-block micronucleus assay CBMN in bone marrow and peripheral blood lymphocytes is now one of the most micronkcleus in vivo cytogenetic assays in the field of genetic toxicology.
