چکیده

OBJECTIVE In the search of new human genotoxic biomarkers, the single cell gel electrophoresis assay has been proposed as a sensible alternative. MATERIAL AND METHODS This technique detects principally single strand breaks as well as alkali-labile and repair-retarded sites. RESULTS Herein we present our experience using the single cell gel electrophoresis assay in human population studies, both occupationally and environmentally exposed. CONCLUSIONS We discuss the assay feasibility as a genotoxic biomarker.

Radioresponse of human lymphocytes pretreated with boron and gadolinium as assessed by the comet assay

Background: Boron and gadolinium are among the nuclides that hold a unique property of being a neutron capture therapy agent. Neutron beams have often a considerable portion of gamma rays with fast neutrons. Gamma rays, as beam contaminants, can cause considerable damage to normal tissues even if such tissues do contain high boron concentrations. Materials and Methods: The modification of radio...

Assessment of DNA damage induced by butachlor on Cyprinuscarpio(L. 1758) using Single Cell Gel Electrophoresis

Butachlor (N-(butoxymethyl)-2-chloro-N-2, 6-diethylacetanillide) is widely used chloroacetanilide herbicide in Asian region, especially in the north of Iran. Several studies have been reported on toxicity of butachlor, but little information is accessible on DNA damaging potential. Thus, the present study was undertaken to investigate of DNA damage by butachlor in Cyprinuscarpio(Pisces: Cyprini...

APPLICATION OF TWO-DIMENSIONAL ELECTROPHORESIS AND NIH 3T3 CELL TRANSFECTION ASSAY IN THE STUDY OF TUMOR-AS SOCIATED PROTEINS AND GENOMIC DNA TUMOROGENICITY IN MALIGNANT HUMAN ESOPHAGEAL SPECIMENS

Total protein and DNA extracted from histologically diagnosed normal nonmalignant and esophageal tumor tissues were used for analysis of polypeptides pattern by two-dimensional gel electrophoresis and DNA transforming activity in NIH 3T3 cell transfection assay, respectively. In comparison to normal tissues, eight polypeptides underwent down-regulation or disappeared, while seven polypeptid...

Evaluation of incubation temperatures on DNA damages of the Caspian trout (Salmo trutta caspius Kessler, 1877) single cells through developmental stages by Comet assay

Caspian trout (Salmo trutta caspius Kessler, 1877) is an endemic migratory subspecies in the Caspian Sea, possessing ecologic-economic and biodiversity greatly value. Among habitat factors, temperature and its possible effects on the Caspian trout genome were considered in this research. During Embryonic developmental stages (fertilization–hatching), genomic alterations of single cells were ass...
