Ataxia telangiectasia is one of a group of recessive hereditary genomic instability disorders and is characterized by progressive neurodegeneration, immunodeficiency and cancer susceptibility. Heterozygotes for the mutated gene are more susceptible to cancer and to ischaemic heart disease. The affected gene, ATM (ataxia telangiectasia mutated), has been cloned and codes for a protein kinase (AT...
PURPOSE DNA damage checkpoints are initiated by its sensor proteins of the phosphoinositide-3-kinase-related protein kinase family, including ataxia-telangiectasia mutated, ataxia-telangiectasia and Rad3-related, and DNA-dependent protein kinase catalytic subunit (DNA-PKcs). We hypothesized that polymorphisms in these genes may alter the regulation of DNA repair and the risk of lung cancer. E...
Magnetic resonance imaging (MRI) research in identifying altered brain structure and function in ataxia-telangiectasia, an autosomal recessive neurodegenerative disorder, is limited. Diffusion-weighted MRI were obtained from 11 ataxia telangiectasia patients (age range, 7-22 years; mean, 12 years) and 11 typically developing age-matched participants (age range, 8-23 years; mean, 13 years). Gray...
Stability and repair of DNA is of principal importance in cell survival. Heme oxygenase-1 (HO-1; Hmox1) is critical in maintaining cellular homeostasis, in large part through its ability to generate CO, but neither molecule has been studied in the setting of DNA damage. Naïve Hmox1(-/-) mice exhibit excessive tissue levels of γ-histone H2A, whereas administration of genotoxic stressors or irrad...

Ataxia-Telangiectasia (AT) is a rare human neurodegenerative autosomal recessive multisystem disease that is characterized by a wide range of features including, progressive cerebellar ataxia with onset during infancy, occulocutaneous telangiectasia, susceptibility to neoplasia, occulomotor disturbances, chromosomal instability and growth and developmental abnormalities. Mitochondrial DNA (mtDN...
BACKGROUND Our understanding of the effect of ataxia-telangiectasia mutated gene mutations on brain structure and function is limited. In this study, white matter motor pathway integrity was investigated in ataxia telangiectasia patients using diffusion MRI and probabilistic tractography. METHODS Diffusion MRI were obtained from 12 patients (age range: 7-22 years, mean: 12 years) and 12 typic...
