SIRT1 Attenuates the Neurotoxicity Associated with Alzheimer’s Disease, via A Mechanism Which May Involve Regulation of Peroxisome Proliferator-activated Receptor γ Coactivator 1-α

For your weekly Pathology news, Lab.Equipment has handpicked this notable article from The American Journal of Pathology for you:

To investigate whether silent mating-type information regulation 2 homolog 1 (SIRT1) plays a neuroprotective role in connection with Alzheimer’s disease (AD), brain tissues from patients with AD and APP/PS1 mice as well as primary rat neurons exposed to oligomers of amyloid-β peptide (AβO) were used. The animals were treated with resveratrol (RSV) or suramin for two months; and cell cultures with RSV, suramin, the PGC-1α stimulator ZLN005 and transient transfection with PGC-1α RNA silence. The level of SIRT1 in brain tissues from patients with AD and APP/PS1 mice, as well as in primary neurons exposed to AβO was decreased, including SIRT1 proteins in nuclear or mitochondria....
