N normal phenotype
cellular
• three fold increase in micronuclei and nucleoplasmic bridges after etoposide treatment as compared to controls
• three fold increase in chromosomal aberrations after etoposide treatment as compared to controls
• increased number of chromosomal breaks and exchanges in metaphase spreads of mice treated with etoposide
• severe reduction of metaphase spreads in cultured embryonic fibroblasts treated with etoposide

homeostasis/metabolism
• are hypersensitive to etoposide damage but sensitivity is normal to gamma radiation

growth/size/body
• etoposide causes a progressive and severe weight loss unlike the transient weight loss seen in controls

digestive/alimentary system
• villous atrophy 6 days after treatment with etoposide

hematopoietic system
• reduced cellular content after etoposide treatment
• 30-50% loss of pro-B cells, 95%loss of pre-B cells and immature B cell precursors
• losses are not significantly different from controls similarly treated with etoposide
• almost completely eliminated by etoposide treatment
• two fold increase relative to controls in micronucleated polychromatic erythrocytes in bone marrow from etoposide treated mice
• reduced cellular content after etoposide treatment

immune system
• 30-50% loss of pro-B cells, 95%loss of pre-B cells and immature B cell precursors
• losses are not significantly different from controls similarly treated with etoposide
• almost completely eliminated by etoposide treatment
• reduced cellular content after etoposide treatment
• reduced cellular content after etoposide treatment

endocrine/exocrine glands
• reduced cellular content after etoposide treatment
