Abstract
The aspartyl protease ?-site A?PP-cleaving enzyme 1 (BACE1) catalyzes the rate-limiting step in A? production, a peptide at the nexus of neurodegenerative cascades in Alzheimer Disease dementia. Leptin may offer protection against Alzheimer?s dementia as this adipocytokine can reduce A? production and decrease BACE1 activity and expression levels. However, the signaling cascades involved in the leptin-induced mitigation in A? levels and BACE1 expression levels have not been elucidated. We have demonstrated that NF-?B positively regulates BACE1 transcription. NF-?B activity is tightly regulated by the mammalian sirtuin SIRT1. Multiple studies have cogently evinced that leptin activates the metabolic master regulator SIRT1. In this study, we determined the extent to which SIRT1 expression and activity regulate the leptin-induced attenuation in BACE1 expression and A? levels. This study also elucidated and delineated the signal transduction pathways involved in the leptin induced mitigation in BACE1 expression.
