In this study we tested the genotoxicity of two widely used phenolic antioxidants, butylated hydroxyanisole (BHA) and tert-butylhydroquinone (TBHQ) in multiple mouse organs using the alkaline comet assay. Tissue samples from four organs (stomach, liver, kidney and bone marrow) were collected from male mice at 3 and 24 h post treatment with BHA (800 mg/kg) or TBHQ (400 mg/kg) and examined for ge...
A protocol for DNA damage assessment by the single-cell gel (SCG)/comet assay in human urinary bladder washing cells was established. Modifications of the standard alkaline protocol included an increase to 2% of sodium sarcosinate in the lysis solution, a reduction in the glass-slide area for comet analysis, and a cutoff value for comet head diameter of at least 30 microm, to exclude contaminat...
The increasing use of single cell gel electrophoresis (the comet assay) highlights its popularity as a method for detecting DNA damage, including the use of enzymes for assessment of oxidatively damaged DNA. However, comparison of DNA damage levels between laboratories can be difficult due to differences in assay protocols (e.g. lysis conditions, enzyme treatment, the duration of the alkaline t...
. در این مطالعه، احتمال شکسته شدن (فرگمنته شدن) dna طی تمایز اریتروئیدی سلول های اریترولوکمیک tf-1بررسی شد. به منظور تمایز اریتروئیدی سلول های tf-1، این سلول ها با فاکتورهایی مانند iu/ml 20 اریتروپویتین ، به همراه pg/ml 10000 gm-csf ، تیمار شدند. تکثیر سلول ها با روش سنجشmtt در سلول های کنترل و سلول های تیمار شده ارزیابی شد. همچنین سنتز هموگلوبین با روش های رنگ آمیزی بنزیدین ، الکتروفورز پروتئی...
The intention was to evaluate the possible in vivo genotoxic potential in different cell-types, of a methanol extract obtained from the plant stem of Cotinus coggygria Scop., using the sex-linked recessive lethal (or SLRL) test and alkaline comet assay. The SLRL test, revealed the genotoxic effect of this extract in postmeiotic and premeiotic germ-cell lines. The comet assay was carried out on ...
High intensity exercise can enhance the production of reactive oxygen and nitrogen free radical species, which may cause a number of perturbations to cellular integrity, including deoxyribonucleic acid (DNA) modification. In the absence of adequate DNA repair, it is theoretically possible that several biological disorders may ensue, in addition to premature aging. This striking hypothesis and s...
