Abstract
© 2020 Elsevier Inc. Genetic engineering for neuronal cell activity labeling and neuronal cell activity modulation are invaluable for elucidating the underlying characteristics of the brain and neurons. In this study, ferritin fusion protein (FFP) was combined with Tet expression construct under a modified immediate-early gene (IEG) Arc/Arg3.1 promoter so-called SARE-ArcMin. This expression system is a neuronal activity-dependent expression module for nano-ferritin, a radio/magnetic wave-sensitive protein well-accepted as a potential recombinant neuronal actuator. The system was characterized in transcriptional and translational levels in human neuroblastoma SH-SY5Y cells. The mRNA and protein expression levels of nano-ferritin were significant in the activated neurons suggesting that the activity dependent expression patterns of the ferritin also acted as a neuronal cell activation indicator. The system sufficed the need for precise neuronal cell activity specific expression and demonstrated a platform that suggested the use of the nano-ferritin for the study of neuronal cells.
