The Regulation of ZIP8 by Dietary Manganese in Mice.

ABSTRACT: ZIP8 is a newly identified manganese transporter. A lack of functional ZIP8 results in severe manganese deficiency in both humans and mice, indicating that ZIP8 plays a crucial role in maintaining body manganese homeostasis. Despite a well-acknowledged connection between ZIP8 and manganese metabolism, how ZIP8 is regulated under high-manganese conditions remains unclear. The primary goal of this study was to examine the regulation of ZIP8 by high-manganese intake. We used both neonatal and adult mouse models in which mice were supplied with dietary sources containing either a normal or a high level of manganese. We discovered that high-manganese intake caused a reduction in liver ZIP8 protein in young mice. Since a decrease in hepatic ZIP8 leads to reduced manganese reabsorption from the b
