mortality/aging
• mice die rapidly after birth and by P10 to P14 no mice are alive
• though present in Mendelian ratios at E20, mice die rapidly after birth

cellular
• mouse embryonic fibroblasts (MEFs) subjected to UV irradiation and staurosporine fail to exhibit evidence of normal apoptosis 24hrs after treatment unlike in wild type MEFs
• following injection of fetal liver cells into a RAG-deficient background, thymocyte apoptosis induced by mitochondrial pathways is decreased
• however, thymocytes are still sensitive to death receptor mediated apoptosis
• mouse embryonic fibroblasts (MEFs) subjected to UV irradiation and staurosporine fail to undergo apoptosis
• MEFs exhibit decreased apoptosis following stimulation of the death receptor pathway
• following induction of apoptosis, MEFs fail to exhibit a loss of mitochondrial membrane potential

cardiovascular system
• at E20, the ventricular wall is disorganized and noncompacted

nervous system
• in 10% of mice

immune system
• following injection of fetal liver cells into a RAG-deficient background, thymocyte apoptosis induced by mitochondrial pathways is decreased
• however, thymocytes are still sensitive to death receptor mediated apoptosis

hematopoietic system
• following injection of fetal liver cells into a RAG-deficient background, thymocyte apoptosis induced by mitochondrial pathways is decreased
• however, thymocytes are still sensitive to death receptor mediated apoptosis

endocrine/exocrine glands
• following injection of fetal liver cells into a RAG-deficient background, thymocyte apoptosis induced by mitochondrial pathways is decreased
• however, thymocytes are still sensitive to death receptor mediated apoptosis
