[ 1 ] - Potential protective roles of phytochemicals on glutamate-induced neurotoxicity: A review

Glutamate, as an essential neurotransmitter, has been thought to have different roles in the central nervous system (CNS), including nerve regeneration, synaptogenesis, and neurogenesis. Excessive glutamate causes an up-regulation of the multiple signaling pathways, including phosphoinositide-3 kinase/protein kinase B (PI3K/Akt), Akt/mammalian target of rapamycin (mTOR) protein, mitogen-activat...

[ 2 ] - Rheum turkestanicum Janisch Root Extract Mitigates 6-OHDA-Induced Neuronal Toxicity Against Human Neuroblastoma SH-SY5Y Cells

Background and Objective: Rheum turkestanicum (R. turkestanicum) has been known to reduce inflammation and has antioxidant properties such as protective effect in neurons. This study aimed to determine the effects of R. turkestanicum on neuronal toxicity induced by the pro-parkinsonian neurotoxin 6-hydroxydopamine (6-OHDA) in neuroblastoma SH-SY5Y cells. Materials and Methods: MTT and DNA frag...
