Abstract

Activation of the p53 tumor suppressor leads to either a cell cycle arrest or to apoptosis and the factors that influence these responses are poorly understood. It is clear, however, that p53 regulates these processes by inducing a series of downstream target genes. One recently identified p53- target gene, EI24 (alias PIG8), induces apoptosis when ectopically expressed. To better understand the biological properties of EI24 and its potential relevance to disease, in particular cancer, we determined the chromosomal location and pattern of gene expression of EI24. EI24 is widely expressed in adult tissues and throughout mouse embryogenesis. The genomic locus of EI24 was mapped to the proximal region of mouse chromosome 9 and human chromosome 11q23· q24, a region frequently altered in human cancers. These results suggest that EI24 may play an important role in the p53 tumor suppressor pathway. Copyright (C) 2000 S. Karger AG, Basel.
