Alzheimer's disease (AD) and neuroblastoma are distinct conditions that affect the nervous system. However, they share some molecular similarities, particularly concerning the amyloid precursor protein (APP) and related pathways. While previous studies have demonstrated a correlation between neurodegenerative diseases and various tumors, the causality and direction of their relationship remain unclear. Oleacein, one of the most abundant polyphenols in Extra Vergin Olive Oil (EVOO) may exert neuroprotective and/or antitumor effects. In this study, we explored the effects of the polyphenol oleacein, obtained by a simple and efficient sustainable semi-synthesis starting from natural oleuropein, on AD-related genes in SHSY5Y, a human neuroblastoma cell line, and in 3Tg-iAstro cells, immortalized astrocytes from the hippocampus of 3xTg-AD mice, to identify potential shared biological pathways.
