LncRNA17A regulates autophagy and apoptosis of SH-SY5Y cell line as an in vitro model for Alzheimer's disease

Considerable evidence suggest that a variety of Long-non-coding RNAs (LncRNAs) are widely implicated in several neurodegenerative disorders. The present study aims to investigate the regulatory effect of LncRNA 17A in an in vitro model of Alzheimer's disease (AD). AD cell model was established by treating the SH-SY5Y cells with amyloid beta peptide 1-42, and then the cells were transfected with 17A shRNA and pcDNA-17A. Apoptosis, migration, invasion and ELISA assays were performed to investigate the effect of differentiated 17A expression level on AD cell line. It was determined that 17A-overexpressing promotes autophagy, induces neurodegenration and deactivates GABAB signaling. In conclusion, our results demonstrated that the dysregulation of LncRNA 17A was involved in cellular functions and biological processes of neuroblastoma cells in an AD cell model, shedding light on the diagnostic value and therapeutic potential of LncRNA 17A for AD intervention.
