Background/Aim:
Activation of AKT serine/ threonine kinase (AKT) predicts poor outcome in neuroblastoma, which highlights the potential of the AKT pathway as a promising target for neuroblastoma treatment. Several studies reported that blockade of α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptors (AMPARs) reduces proliferation in glioblastoma or lung cancer by inhibiting AKT and extracellular signal-related kinase (ERK) pathways. In this study, we examined the effect of the AMPAR antagonist perampanel on human neuroblastoma cells.
Materials And Methods:
Cell proliferation, caspase activity, and western blot assays were performed to determine the effect of perampanel on the KP-N-SI9s human neuroblastoma cell line.
Results:
Perampanel inhibited cell proliferation without triggering apoptosis in neuroblastoma cells. Down-regulation of AKT protein levels, AKT phosphorylation, and ERK1/2 phosphorylation were also observed in neuroblastoma cells with perampanel treatment.
Conclusion:
Perampanel inhibits neuroblastoma cell proliferation through down-regulation of AKT and ERK pathways and has potential for the treatment of neuroblastoma.
Insights
Perampanel, an alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptor antagonist, inhibits neuroblastoma cell growth by reducing AKT and ERK pathway signaling. This suggests perampanel
Area of Science:
- Oncology
- Neuroscience
- Pharmacology
Background:
- Activation of AKT serine/threonine kinase (AKT) is linked to poor outcomes in neuroblastoma.
- The AKT pathway is a potential therapeutic target for neuroblastoma treatment.
- Blockade of alpha-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid receptors (AMPARs) inhibits AKT and ERK pathways in other cancers.
Purpose of the Study:
- To investigate the effect of the AMPAR antagonist perampanel on human neuroblastoma cells.
- To determine if perampanel affects neuroblastoma cell proliferation and associated signaling pathways.
Main Methods:
- Human neuroblastoma cell line (KP-N-SI9s) was treated with perampanel.
- Assays performed included cell proliferation, caspase activity, and Western blot analysis.
- Western blot was used to assess protein levels and phosphorylation of AKT and ERK1/2.
Main Results:
- Perampanel significantly inhibited neuroblastoma cell proliferation.
- Apoptosis was not induced by perampanel treatment.
- Perampanel treatment led to down-regulation of AKT protein levels, AKT phosphorylation, and ERK1/2 phosphorylation.
Conclusions:
- Perampanel effectively inhibits neuroblastoma cell proliferation.
- The mechanism involves the down-regulation of both AKT and ERK signaling pathways.
- Perampanel demonstrates potential as a therapeutic agent for neuroblastoma treatment.
