Abstract

Rats were fed 100 μM aluminum maltolate for one year in their drinking water. Brain aluminum contents have increased 4.2-fold in the aluminum-treated group, whereas no significant changes in the body weight, brain weight, and brain protein content were observed. Long-term aluminum feeding induced apoptosis as assessed by the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method and showed activatory effects on the catalytic efficiency (k_cat/K_M) of monoamine oxidase-A and monoamine oxidase-B up to 1.9- and 3.8-fold, respectively. The expression level of monoamine oxidase isotypes on the Western blot remained unchanged between the two groups, suggesting a change in post-translational regulation of the activities of monoamine oxidase isotypes by long-term aluminum feeding.
