In mammals, Immunoglobulin light chain (IgL) are localized to two chromosomal regions (designated kappa and lambda). Here we report a genome-wide survey of IgL genes in the zebrafish revealing (V(L)-J(L)-C(L)) clusters spanning 5 separate chromosomes. To elucidate IgL loci present in the zebrafish genome assembly (Zv6), conventional sequence similarity searches and a novel scanning approach bas...
During childhood, the thyroid gland is one of the most sensitive organs to the carcinogenetic effects of ionizing radiation that may lead to papillary thyroid carcinoma (PTC) associated with RET/PTC oncogene rearrangement. Exposure to ionizing radiation induces a transient "oxidative burst" through radiolysis of water, which can cause DNA damage and mediates part of the radiation effects. H(2)O...
Defective V(D)J rearrangement of immunoglobulin heavy or light chain (IgH or IgL) or class switch recombination (CSR) can initiate chromosomal translocations. The DNA-damage kinase ATM is required for the suppression of chromosomal translocations but ATM regulation is incompletely understood. Here, we show that mice lacking the ATM cofactor ATMIN in B cells (ATMIN(ΔB/ΔB)) have impaired ATM sign...
Background: B-cell lymphoblastic leukaemia (B-ALL) is a malignancy of immature B-cells with several described recurrent genetic abnormalities. These have distinct clinico-pathological associations and show regional variation in prevalence. In all previously reported series, the translocation t(1;19) uncommon, comprising 40 years age, but also 8.1% children. Crude survival rates were overall poo...
Chromosomal instability is a hallmark of cancer. The results of this instability can be observed in the karyotypes of many cancerous genomes, which often contain a variety of aberrations. In this study we introduce a new approach for analyzing rearrangement events in carcinogenesis. This approach builds on a new effective heuristic for computing a short sequence of rearrangement events that may...
