cellular
• mice treated with tamoxifen at P10 (3 doses every 2 days) exhibit apoptosis in the dentate gyrus at P20

growth/size/body
• mice treated with tamoxifen at P7 exhibit a decreased body size at P13
• mice treated with tamoxifen at P10 (3 doses every 2 days) exhibit a modest effect on brain size at P20

nervous system
• mice treated with tamoxifen at P10 (3 doses every 2 days) exhibit apoptosis in the dentate gyrus at P20
• mice treated with tamoxifen at P7 exhibit decreased brain size
• however, mice treated with tamoxifen at P21 (3 doses every 2 days) exhibit little overall effect on brain size or structure

• mice treated with tamoxifen at P21 (3 doses every 2 days) exhibit a decrease in oligodendrocyte numbers in the dentate gyrus but not in the cortex at P33
• mice treated with tamoxifen at P21 show a reduction of mature neurons in the dentate gyrus, the hippocampal CA3 region and the cerebellum
• myelin-producing oligodendrocytes from mice treated with tamoxifen at P21 show a reduction in myelination
• mice treated with tamoxifen at P10 (3 doses every 2 days) exhibit a loss of myelination in the dentate gyrus at P20

mortality/aging
• mice do not survive past 5 days of age

cellular
• mice show abundant cell death from E13 onwards throughout the developing nervous system
• apoptosis is seen in the developing cerebellum
• reduction in proliferation is seen in the developing nervous system
• primary astrocytes show a defect in the repair of DNA double strand breaks after bleomycin treatment
• primary cortical non-replicating astrocytes show a deficiency in the repair of DNA damage after treatment with ionizing radiation, hydrogen peroxide, or camptothecin

nervous system
• hemorrhage in the brain
• mice show abundant cell death from E13 onwards throughout the developing nervous system
• apoptosis is seen in the developing cerebellum
• reduction in cerebellar interneurons
• smaller cortex
• however, the layering of the cortex still occurs
• reduction in numbers of neurons in the cortex, particularly in later-born upper cortical layers

cardiovascular system
• hemorrhage in the brain

homeostasis/metabolism
• primary astrocytes show a defect in the repair of DNA double strand breaks after bleomycin treatment
