Enhanced Frequency of Sister Chromatid Exchanges Induced by Diepoxybutane Is Specific Characteristic of Fanconi Anemia Cellular Phenotype

Induction by alkylating agents of sister chromatid exchanges and chromatid breaks in Fanconi's anemia.

Sister chromatid exchanges, which may reflect chromosome repair in response to certain types of DNA damage, provide a means of investigating the increased chromosome fragility characteristic of Fanconi's anemia. By a recently developed technique using 33258 Hoechst and 5-bromodeoxyuridine, it was observed that the baseline frequency of sister chromatid exchanges in phytohemagglutinin-stimulated...

G2 chromosomal radiosensitivity and background frequency of sister chromatid exchanges of peripheral blood lymphocytes of breast cancer patients

Background: Chromosomal alterations play an important role in carcinogenesis. Enhanced chromosomal radiosensitivity is shown for many cancer predisposition conditions including breast cancer. In this study chromosomal radiosensitivity and the frequency of background sister chromnatid exchanges (SCE) in lymphocytes of normal individuals and breast cancer patients was compared. Materials...

Frequency of Hypothyroidism in Fanconi Anemia

Background: Fanconi anemia (FA) is a rare, autosomal recessive (AR) and multifactorial disorder. A high prevalence of FA observed in Iran is perhaps due to the high rate of consanguineous marriages. This study investigates the extent of short stature in patients with FA, the frequency of hypothyroidism in FA and the correlation between height and hypothyroidism. Methods: Eighteen patients with ...

Induction of sister chromatid exchanges in human lymphocytes by DTPA.

The chelating agent, diethylenetriaminepentaacetic acid (DTPA) is a non-registered drug used in the treatment of over-exposure to heavy metals such as iron, zinc and lead (Fahey et al., 1961; Brugsch et al., 1965). DTPA has also been used on a few occasions in the United Kingdom when individuals have inhaled plutonium dust or received contaminated wounds (Schofield and Dolphin, 1974). These pat...
