AI Article Synopsis
- * The study assessed the use of siRNA to target Akt and induce cell death in neuroblastoma cells (NBFL) exposed to anoxia/reoxygenation conditions.
- * Results showed that siRNA targeting Akt led to increased apoptotic cell death in NBFL cells, particularly under anoxic conditions, highlighting the potential for therapeutic applications against neuroblastoma.
Article Abstract
Overactivation of the PI3 kinase/Akt pathway plays an essential role in the development and progression of various tumors. Akt is a key component of this pathway and hyperactivated in different tumors including neuroblastoma and glioma. In the present study, we tested the therapeutic efficacy of siRNA targeting Akt in inducing apoptotic cell death in NBFL cells (a human neuroblastoma cell line) subjected to anoxia/reoxygenation (A/R), a process that has been shown to modulate growth and progression of malignant tumors. We observed that siRNA targeting Akt effectively induced apoptotic cell death in NBFL cells (as determined by TUNEL assay and activated caspase-3 immunoreactivity) under normoxic conditions, an effect that was greatly enhanced under conditions of A/R. These findings underscore the importance of Akt signaling in promoting survival of neuroblastoma cells and may have potential therapeutic applications.
