Strain development Developed by Drs. Kohki Kawane and Shigekazu Nagata at Osaka University in 2003. A neomycin cassette replaced exons 1-6 and part of 7 of Dffb gene. The mutant mice were backcrossed to C57BL/6.
Strain description B6;129-Dffb<tm1Osa>. CAD, Caspase-activated DNase is an endonuclease that is activated in apoptotic cells. CAD deficient thymocytes did not undergo apoptotic DNA fragmentation, but their DNA was digested by thymic macrophages that effectively phagocytosed the
apoptotic thymocytes. This strain is useful for elucidation of the function of CAD gene.
Colony maintenance Backcross to C57BL/6 (Heterozygote x C57BL/6NCrlCrlj)
Homozygous mutant mice show no gross developmental abnormalities and are fertile with normal fecundity.
