| Outline of Final Research Achievements |
We studied the function of stress-response transcription factor ATF7 by using the ATF7 gene knockout mouse. At first, we found that ATF7 made complex with Ku70/Ku80 and telomerase and regulated telomere length. This function was found not only in mouse cells but also in human cells.
Second, we found that ATF7 suppressed a group of genes encoding factors involved in innate immunity in macrophages. Treatment with lipopolysaccharide increased basal expression of target genes. And these increased expressions were maintained for long periods, which enhanced resistance to pathogens. ATF7 might therefore be important in controlling memory in cells of the innate immune system.
