Project description:Skin is usually exposed during human exposures to ionizing radiation, however there are few experiments that evaluate the radiation responsiveness of the cells of the epidermis (keratinocytes) and those of the dermis (fibroblasts) in the same studies. We evaluated the transcriptional responses of quiesent primary keratinocytes and fibroblasts from the same individual and compared them with quiescent keratinocytes and fibroblasts that were immortalized by human telomerase (hTert). The primary transcriptional responses to 10-500 cGy ionizing radiation were p53-mediated responses; however, we did identify distinct responses between the keratinocytes and the fibroblasts.

Experiment Overall Design: Four cell types (primary keratinocytes, hTert immortalized keratinocytes, primary fibroblasts, hTert immortalized fibroblasts) grown to quiescence, treated with 0, 10, 100 or 500 cGy gamma irradiation, RNA collected at 4 hrs.

Project description:Most studies have analysed the effects of high dose radiation such as atomic bomb survivors in Japan, people exposed during the Chernobyl nuclear accident, patients undergoing radiation therapy, uranium miners, etc. However, it has been difficult to measure and assess the risk of cancer in people exposed to lower doses of ionising radiation, such as the people living at high altitudes, who are exposed to more natural background radiation from cosmic rays than people at sea level. We measured the genomic response to X-ray ionising radiation (10 cGy and 100 cGy) in a skin tissue model to compare the effects of low and high dose ionising radiation at different time points. The microarray data was then analysed using state-of-the art “upside-down pyramid” computational systems biology methods to identify genes contributing to the difference in the response to the different radiation doses. The model is reconstructed skin tissue, which is composed of keratinocytes that make up the epidermal layer, and fibroblasts that make up the dermal layer of the skin. Tissues were irradiated with 0, 10, and 100 cGy X-ray radiation. Skin plugs were harvested at 0, 3, 8, and 24 hours post irradiation.
