| 内容記述 | HiCEP (High-coverage expression profiling) is a novel comprehensive analysis method which is based on DNA finger printing and PCR amplification. It enables to detect any altered gene expression among 60-70% of all the actually transcribed genes in any eukaryotic cells and tissues. We previously applied HiCEP to a primary culture of normal human fibroblasts and observed gene expression responding to X-ray at the very low dose (10 mGy). As the result of screening approximately 23.000 transcripts, we have identified a set of CXC chemokines (CXCL1, CXCL2, CXCL6 and CXCL8) up-regulated by the 10 mGy X-rays in the normal human fibroblasts (HFL III) (Cancer Res 2005; 65: 10159-10163). Those genes have hardly been expected from the previous studies using the higher (>100 mGy) doses of radiation. Our observation indicated that different molecular mechanisms are involved in the response to ionizing radiation with different doses /dose rates, suggesting that different cellular responses could be induced by ionizing radiation with different LETs. Accelerated heavy ion particles (at high LET) provide promising effects for radiotherapy of certain types of malignancy, however, the molecular basis of its advantage to gamma rays is not fully understood. This time, we applied HiCEP to compare the gene expression profiles in normal human fibroblasts (HFL III) irradiated with radiation with different LET's. | |||||
