Effect of ginkgolide K on calcium channel activity in Alzheimer's disease.

ABSTRACT: Alzheimer's disease (AD) is a progressive neurodegenerative dementia with the key pathological hallmark of amyloid deposits that may induce mitochondrial dysfunction. Ginkgolide K (GK) has been proven to have neuroprotective effects. The present study sought to explore the neuroprotective effect of GK through regulation of the expression of mitochondrial Ca²⁺ uniporter (MCU) in the pathology of AD. SH-SY5Y cells were cultured and the expression of MCU was enhanced by transfection of MCU recombinant vectors or knockdown by MCU small interfering RNA. The cells were treated with GK and amyloid β (Aβ). Thereafter, the effects of GK, MCU expression and Aβ on viability and apoptosis of SH-SY5Y cells were examined via a WST-1 assay, flow cytometry and Caspase-3/8 activity assays, respe
