In conclusion, we found that miR-186 gradually decreases in the mouse brain cortex during aging.MiR-186 is a potent negative regulator of BACE1 expression in neuronal cells. Both miR-186 and BACE1 are expressed in the brain and are particularly enriched in neurons.Overexpression of miR-186 markedly decreased Aβ level.Down-regulation of miR-186 by the aging process may be involved in the induction of BACE1 expression and thereby cause the accumulation of Aβ during aging.
