nervous system
• tamoxifen treatment leads to the death of catecholaminergic neurons in the brain
• 210 days after tamoxifen treatment, there is a substantial lose (about 50%) of tyrosine hydroxylase positive neurons in the substantia nigra adult mice
• there is also a drop in the total number of neurons in the substantia nigra after tamoxifen treatment
• 210 days after tamoxifen treatment, there is a substantial lose (about 2.5-fold) of tyrosine hydroxylase positive neurons in the ventral tegmentum of adult mice
• there is also a drop in the total number of neurons in the ventral tegmentum after tamoxifen treatment
• neurons are diminished in the locus ceruleus 210 days after tamoxifen treatment
• fiber density of tyrosine hydroxylase positive neurons are diminished 210 days after tamoxifen treatment
• fiber density of tyrosine hydroxylase positive neurons are diminished 210 days after tamoxifen treatment

behavior/neurological
• 100 days after tamoxifen injection, mice have reduced activity in open field tests with about 25% less activity
• resting time of mice in open field tests increases significantly 100 days after tamoxifen treatment
• this hypoactivity worsens with the passage of time

cardiovascular system
• tyrosine hydroxylase positive neurons are diminished by more than half 210 days after tamoxifen-treatment
