内容記述 | Recent improvements in DNA microarray technologies and bioinformatics have made it possible to look for common features of ionizing radiation (IR)-responsive genes and their regulatory regions. We analyzed the promoters of 217 IR- responsive human genes, compiled from microarray databases available in the literature. Using the DBTSS database, the transcriptional start sites were determined, and the core promoter elements, such as the TATA-box, initiator (Inr), GC- box and CCAAT-box, were searched for in the -1000bp/+200bp region of each gene by using MATCH. It was found that the frequency of Inr in IR-responsive genes was higher than that in general genes, and the frequency of GC-box and CCAAT-box was significantly lower than that in general genes. Utilization of the GC-box and the CCAAT-box in IR-responsive genes was found to be dependent on the TATA-box status, that is, GC-box frequency was low in TATA box-containing genes, and CCAAT-box frequency was also low in TATA-less genes. When correlations between gene functions and frequencies of core promoter elements were examined, no apparent biased use of the core promoter element in association with a specific gene function was observed. It may be speculated that utilization of Inr in the core promoter correlates with appearance of IR-responsive enhancer(silencer) elements in the upstream (downstream) regulatory region. |
