| Summary: | Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by the accumulation of β-amyloid plaques and hyperphosphorylated tau proteins in the brain. Cell signaling pathways such as PI3K/Akt are known to play an essential role in regulating cell survival, motility, transcription, metabolism, and progression of the cell cycle. Recent studies demonstrated that the disruption of these signaling pathways in neurodegenerative disorders leads to oxidative stress and cell death. Targeting these altered signaling pathways could be considered as the therapeutic approach for neurodegenerative disorders. Ginsenoside Rh1 is known to provide beneficial effects in various diseases such as cancer, diabetes, and inflammation. In this study, human neuroblastoma SH-SY5Y cells were treated with the β-amyloid oligomers alone or in combination with ginsenoside Rh1. We observed that ginsenoside Rh1 was able to attenuate β-amyloid induced oxidative stress and cell death by activating the PI3K/Akt signaling pathway. Based on these findings, we suggest that ginsenoside Rh1 might be an efficacious therapeutic agent for AD.
