چکیده

A fully optimized staining method for detecting sister chromatid exchanges in cultured cells is presented. The method gives reproducibly robust quantitative results. Sister chromatid exchange is a classic toxicology assay for genotoxicity and for detecting alterations to the biochemistry underlying cellular homologous recombination. Growth of cells in the presence of 5'-bromo-deoxyuridine for two rounds of DNA replication followed by collecting metaphase spreads on glass slides, treatment with the UV-sensitive dye Hoechst 33258, long-wave UV light exposure, and Giemsa staining gives a permanent record of the exchanges.

Sister chromatid exchange analysis in some Holstein bulls

Chromosomal appearance of 12 Holstein bulls selected for artificial inseminations were examined bysister chromatid exchanges (SCEs). For differential staining of sister chromatids bromodeoxyuridine (BrdU)was inoculated in lymphocyte cultures. The mean, maximum and minimum number of SCE per cell weredetermined 6.8 ± 1.14, 8.3 ± 1.1 and 5.7 ± 1.5, respectively. SCE frequencies of all animals were...

Study of the Effect of MMC on the Sister Chromatid Exchange in the Human Lymphocytes

Some environmental mutagenic agents cause genomic instability and increase susceptibility of DNA damage. One of them is mitomycin C which is connected to DNA as an alkylating factor and affects susceptible cells to reduction reactions. This drug is used in chemotherapy and treatment of tumors. Study of genomic instability in the presence of different concentrations of MMC can show susceptibilit...

Sister chromatid exchange in Greenleg Partridge and Polbar hens covered by the gene-pool protection program for farm animals in Poland.

A basic assay that detects genotoxic DNA damage disrupting DNA replication and repair mechanisms is the sister chromatid exchange test. The frequency of sister chromatid exchanges was analyzed in chromosomes of the following hen breeds: Greenleg Partridge and Polbar. Chromosome preparations were obtained from our in vitro culture of peripheral blood lymphocytes stained using the fluorescence pl...

cis-Diamminedichloroplatinum(II)-induced sister chromatid exchange: an indicator of sensitivity and heterogeneity in primary human tumor cell cultures.

The effect of cis-diamminedichloroplatinum(II) (cPt) on sister chromatid exchange (SCE) induction was determined in 13 human primary tumor cell cultures. Primary cultures were derived from surgical specimens of solid tumors composed of a variety of histologies. Three to 16 days after biopsy, depending on the growth rate, cultures were treated with graded concentrations of cPt for 1 h and the SC...

Prediction of in vivo tumor response to chemotherapeutic agents by the in vitro sister chromatid exchange assay.

The ability of the in vitro sister chromatid exchange (SCE) assay to predict in vivo tumor drug sensitivity was investigated using a spontaneous hepatocarcinoma in C3Hf/Kam mice and 3 chemotherapeutic agents: melphalan; cis-platinum; and 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU). For hepatocarcinoma cells grown in monolayer culture, melphalan was the most efficient at inducing SCEs, and BCNU,...
