Allopregnanolone Attenuates Aβ25-35-induced Neurotoxicity In PC12 Cells By Reducing Oxidative Stress

[Drareg]

Abstract
Massive accumulation of amyloid beta (Aβ) has been implicated as a pivotal event in the pathogenesis of Alzheimer’s disease. The underlying mechanisms of Aβ-induced neurotoxicity include generation of reactive oxidative species (ROS), inflammation, and neurons loss. Allopregnano-lone (APα), a neurosteroid derive from neuroactive progesterone, has been demonstrated to have neuroprotective properties in vivo and vitro. In the present study, the effects of APα on oxidative damage in Aβ25-35-treated pheochromocytoma (PC12) cells were investigated. Pretreatment of APα significantly attenuated Aβ25-35-induced neuronal death. APα decreased the intracellular ROS generation and reduced lipid peroxidation induced by Aβ25-35. In addition, APα treatment enhanced antioxidant enzyme superoxide dismutase (SOD) activity. This study demonstrates that APα exerts a protective effect against Aβ25-35-induced neurotoxicity in PC12 cells. The protective role of APα likely results from inhibition of oxidative stress.

so.... is this saying something like 5adhp would be dangerous to use because it turns into allopregnanolone

No, it is saying that allopreg protects the brain from stress-induced neurotoxicity.

ok, sorry! great news

No problem. Sometimes studies use impractical language, which can make them difficult to read.
