abstractText | Dad1 is a putative anti-apoptosis gene identified in several distantly related organisms. Expression of Dad1 in transfected cells inhibits apoptosis in vitro. To determine whether Dad1 has a similar function in vivo, we used gene targeting to delete Dad1. Heterozygous adult mice (+/-) show no obvious phenotype or abnormalities, but genotype analysis of over 100 offspring from heterozygous matings detected no weanling, homozygous Dad1 null (-/-) mice. Subsequent analysis of embryos from heterozygous matings detected Dad1 null (-/-) embryos at E3.5 but no later, suggesting Dad1 is required for development beyond the late blastocyst stage. Increased levels of apoptosis were observed in cultured embryos lacking a functional copy of the gene, consistent with an anti-apoptotic role for Dad1. |
