• mice exhibit normal response to 5-FU treatment
• spontaneous or dexamethasome-induced
• dexamethasome-treated mice exhibit increased thymic, splenic, and bone marrow cellularity compared with similarly treated wild-type mice
• dexamethasome-treated mice exhibit increased thymic, splenic, and bone marrow cellularity compared with similarly treated wild-type mice
• Ter-119+ cells exhibit decreased apoptosis compared to in wild-type mice
• Gr-1+ cells exhibit a reduced rate of spontaneous and G-CSF deprivation-induced apoptosis compared with wild-type cells
• aged mice exhibit enhanced myelopoiesis develop neutrophilia unlike wild-type mice
• mice exhibit a 1.5-fold increase in bone marrow cell compared with wild-type mice
• dexamethasome-treated mice exhibit increased thymic, splenic, and bone marrow cellularity compared with similarly treated wild-type mice
• mice exhibit increased Ter-119+ and burst forming unit erythroid cells in the peripheral blood, bone marrow, and spleen compared with wild-type mice
• in adult and aged mice
• mice exhibit a 1.96-fold increase in white blood cell compared with wild-type mice
• the increase in white blood cell is severe in wild-type mice transplanted with bone marrow from homozygous mice
• at 18 months, mice exhibit increased white blood cells compared with wild-type mice
• however, the number of basophils is normal
• in wild-type mice transplanted with bone marrow from homozygous mice
• 4.3-fold in aged mice due to enhanced myelopoiesis
• in wild-type mice transplanted with bone marrow from homozygous mice
• in aged mice
• in the bone marrow and spleen
• mice exhibit an increase in Gr-1+/Mac-1+ cells compared with wild-type mice
• mild in wild-type mice transplanted with bone marrow from homozygous mice
• 1.75-fold in aged mice
• bone marrow-derived mast cells exhibit reduced apoptosis induced by cytokine deprivation compared with wild-type cells
• Background Sensitivity: mice on a congenic 129 background exhibit a greater reduction in mast cell apoptosis induced by cytokine deprivation compared with mice on a C57BL/6 congenic or mixed 129 and C57BL/6 background
