(Submitter supplied) DNA damage caused by UV radiation initiates cellular recovery mechanisms, which involve activation of DNA damage response pathways, cell cycle arrest and apoptosis. To assess cellular transcriptional responses to UVC-induced DNA damage we compared time course responses of human skin fibroblasts to low and high doses of UVC radiation known to induce a transient cellular replicative arrest or apoptosis, respectively. more...

(Submitter supplied) The kinetics of DNA repair and RNA synthesis recovery in human cells following UV-irradiation were assessed using nascent RNA Bru-seq and quantitative long PCR. It was found that UV light inhibited transcription elongation and that recovery of RNA synthesis occurred as a wave in the 5’-3’ direction with slow recovery and TC-NER at the 3’ end of long genes. RNA synthesis resumed fully at the 3’-end of genes after a 24-hour recovery in wild-type fibroblasts, but not in cells deficient in transcription-coupled nucleotide excision repair (TC-NER) or global genomic NER (GG-NER). more...

(Submitter supplied) Rationale: During excessive pressure or overload, cardiac cells are subjected to increased mechanical stress. We investigate how the stress response of cardiac cells to mechanical stress can be compared to genotoxic stresses induced by DNA damaging agents. Methods: Cultures enriched for cardiomyocytes and cultures of fibroblasts were derived from ventricles of neonatal rat hearts. In three independent experiments, both cell cultures were subjected to mechanical stress (cyclic stretch at 60 cycles/min), UV irradiation (10 J/m2), or X-rays (8.5 Gy). more...

(Submitter supplied) 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 analyses. Fibroblasts exhibited >90% arrest of progression from G2 to M at 2 h and from G1 to S at 6 and 12 h post-IR. more...

(Submitter supplied) 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 that arrest growth and suppress genetic instability. NHMs displayed effective G1 and G2 checkpoint responses to ionizing radiation-induced DNA damage. more...

(Submitter supplied) 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 expression levels of >400 cell-cycle-regulated genes in normal human fibroblasts based on the proportions of cells in each phase of the cell cycle. more...

(Submitter supplied) DNA repair is an essential cellular process required to maintain genomic stability. Every cell is subjected to thousands of DNA lesions daily under normal changes in transcription. Transcription is a primary process where protein amount and function can be regulated. One aspect of the transcriptional IR response that little is known about on a whole genome basis is alternative transcription. These investigations focus on the response to IR at the exon level in human cells but also at the whole gene level. more...

(Submitter supplied) Despite widespread use of sunscreens that minimize erythema by blocking ultraviolet B (UVB) radiation, incidence rates of melanoma continue to rise. In considering this disparity between intervention and disease prevalence, we investigated the in vivo transcriptome of human skin treated with sunscreen and solar-simulated radiation (ssR). A focal skin area of healthy participants was exposed to ssR at 1 minimal erythema dose (MED), 0.1 MED or 100 J/m2 with or without prior application of sunscreen, or to non-UVB-spectrum of ssR (solar-simulated UVA/visible/infrared radiation: ssA). more...

(Submitter supplied) In response to DNA double strand damage, ongoing transcription is inhibited to facilitate accurate DNA repair while transcriptional recovery occurs after DNA repair is complete. However, the mechanisms at play and identity of the transcripts being regulated in this manner are unclear. In contrast to the situation following UV damage, we found that transcriptional recovery after ionizing radiation (IR) occurs in a manner independent of the HIRA histone chaperone. more...
