The changes in global gene expression in response to DNA damage may derive from either direct induction or repression by transcriptional regulation or indirectly by synchronization of cells to specific cell cycle phases, such as G1 or G2. We developed a model that successfully estimated the express...

Cell cycle arrest and transcriptional responses to ionizing radiation (IR)-induced DNA damage were quantified in telomerase-expressing human diploid fibroblasts. Assays of clonal expansion established 1.5 Gy IR as the D0 dose in three fibroblast lines and this dose was used in all subsequent analyse...

Defects in DNA damage responses may underlie genetic instability and malignant progression in melanoma. Cultures of normal human melanocytes (NHMs) and melanoma lines were analyzed to determine whether global patterns of gene expression could predict the efficacy of DNA damage cell cycle checkpoints...

Both labelling studies were conducted with C57/BL6J adult male mice, derived from the same supplier and maintained under identical conditions. Eleven adult male C57BL/6JOlaHsd mice (Harlan UK Ltd., Shardlow, UK) of over 12 months of age at the start of the experiment were housed individually in 48 x...
