Acrylamide is a known neurotoxic compound that we get exposed to through food and through the environment. It can cross the placental barrier as well as the blood-brain barrier resulting in exposure of the fetus and the infant child. We used the human neuroblastoma cell line SH-SY5Y to study the effects of non-cytotoxic acrylamide exposure during 9 days of differentiation on two differentially important signaling pathways, i.e. the retinoic acid receptor (RAR) and cAMP response element-binding protein (CREB) signaling in neurons. Our results showed that exposure of non-cytotoxic concentrations of acrylamide during 9 days of differentiation induced altered expression of multiple genes that are part of the CREB and RAR activation pathways, e.g. cellular retinoic acid binding protein 1, retinol binding protein 7, CREB5 and fibroblast growth factor receptor 2. Other well-established neuronal markers such as brain-derived neurotrophic factor, syntaxin binding protein 2, transforming growth factor beta 1, the dopaminergic markers monoamine oxidase A and dopamine receptor D2 as wells as the cholinergic marker choline O-acetyltransferase were also significantly altered by acrylamide. Our results reveal that acrylamide interferes with crucial pathways involved in neuronal differentiation in vitro and raise concerns over the potential toxic outcomes in humans.
