Erythroid microRNA and oxidant status alterations in l-thyroxine-induced hyperthyroid rats: effects of selenium supplementation.

Background: Hypermetabolic state in hyperthyroidism causes oxidative stress. Erythrocytes are the cells that are involved in oxidant equilibrium in an organism and contain microRNA (miRNA). Selenium, which is an essential element for an organism, has antioxidant properties.
