cardiovascular system
N
• tamoxifen-treated mice exhibit normal carotid body morphology
• likely secondary to anemia in tamoxifen-treated
• impaired responsiveness to hypoxia with reduced secretory rate in tamoxifen-treated mice
• lower shifted quantal charge and reduced mean charge per event in tamoxifen-treated mice exposed to mild stimuli
• reduced increase in NADH and mitochondrial function induced by hypoxia in tamoxifen-treated mice
• however, tamoxifen-treated mice exhibit normal hypercapnia and depolarization with high extracellular potassium ion, and normal secretion induced by CO2 and high potassium ion

hematopoietic system
• in tamoxifen-treated mice
• in tamoxifen-treated mice

homeostasis/metabolism
• decreased hypoxic ventilatory response in tamoxifen-treated mice exposed to hypoxic conditions
• however, response to hypercapnia is normal and tamoxifen-treated mice exhibit a small transient hyperventilatory response at the onset of exposure to hypoxia

growth/size/body
• likely secondary to anemia in tamoxifen-treated

muscle
• likely secondary to anemia in tamoxifen-treated

nervous system
• impaired responsiveness to hypoxia with reduced secretory rate in tamoxifen-treated mice
• lower shifted quantal charge and reduced mean charge per event in tamoxifen-treated mice exposed to mild stimuli
• reduced increase in NADH and mitochondrial function induced by hypoxia in tamoxifen-treated mice
• however, tamoxifen-treated mice exhibit normal hypercapnia and depolarization with high extracellular potassium ion, and normal secretion induced by CO2 and high potassium ion
