DISC1 and neuroblastoma: Syncytin-1 induces Ca2+ influx in human neuroblastoma cells and upregulates the expression of transient receptor potential channel C3 (TRPC3) via directly regulating its expression or downregulating disrupted-in-schizophrenia 1 (DISC1), a susceptibility factor for SZ, which is a scaffold protein interacting with various proteins to regulate synaptic processes and dopamine signaling (Chen et al. 2019; Kim et al. 2020).
