Fanconi anemia and DNA repair.
Fanconi anemia (FA) is an autosomal recessive disorder caused by defects in at least eight distinct genes FANCA, B, C, D1, D2, E, F and G. The clinical phenotype of all FA complementation groups is similar and is characterized by progressive bone marrow failure, cancer proneness and typical birth defects. The principal cellular phenotype is hypersensitivity to DNA damage, particularly interstra...
متن کاملFanconi Anemia (Cross)linked to DNA Repair
Fanconi anemia is characterized by hypersensitivity to DNA interstrand crosslinks (ICLs) and susceptibility to tumor formation. Despite the identification of numerous Fanconi anemia (FANC) genes, the mechanism by which proteins encoded by these genes protect a cell from DNA interstrand crosslinks remains unclear. The recent discovery of two DNA helicases that, when defective, cause Fanconi anem...
متن کاملFanconi anemia (FA) binding protein FAAP20 stabilizes FA complementation group A (FANCA) and participates in interstrand cross-link repair.
The Fanconi anemia (FA) pathway participates in interstrand cross-link (ICL) repair and the maintenance of genomic stability. The FA core complex consists of eight FA proteins and two Fanconi anemia-associated proteins (FAAP24 and FAAP100). The FA core complex has ubiquitin ligase activity responsible for monoubiquitination of the FANCI-FANCD2 (ID) complex, which in turn initiates a cascade of ...
متن کاملDNA Damage in Leukocytes from Fanconi Anemia (FA) Patients and Heterozygotes Induced by Mitomycin C and Ionizing Radiation as Assessed by the Comet and Comet-FISH Assay
Background: Lymphocytes of Fanconi anemia (FA) show an increased sensitivity to the alkylating agents such as mitomycin C (MMC), but their responses to gamma-irradiation is controversial. The extent of DNA damage in leukocytes of FA patients following irradiation and MMC treatment was studied at cellular and single chromosome level. Methods: DNA damage induced by gamma-rays and MMC was measure...
