  • Title: The effects of neuronal cell differentiation on TRPM7, TRPM8 and TRPV1 channels in the model of Parkinson's disease.
    Author: Öz A, Çelik Ö.
    Journal: Neurol Res; 2022 Jan; 44(1):24-37. PubMed ID: 34256685.
    Abstract:
    Transient Receptor Potential Melastatin-like 7 (TRPM7), Transient Receptor Potential Melastatin-like 8 (TRPM8) and Transient Receptor Potential Vanilloid-like 1 (TRPV1) channels are expressed in neurological tissues such as brain cortex, dorsal root ganglion and hippocampal neurons and involved in several neurological diseases. The SH-SY5Y neuronal cell line is frequently used as a cellular model of neurodegenerative diseases including Parkinson's disease. The differentiated SH-SY5Y cells have much neuronal structure, function and exaggerated neuronal marker expression. However, we have less data about how differentiation induces TRP channel expression and how TRP channels have a role in cellular functions in Parkinson's disease model in SH-SY5Y cells. Hence, we aimed to investigate the effects of differentiation phenomena on TRPM7, TRPM8 and TRPV1 cation channel expression and related Ca2+ signaling. We also made some other analysis to elucidate TRP channels' function in MPP induced apoptosis, mitochondrial membrane potential levels, intracellular reactive oxygen species production, caspase 3 and caspase 9 enzyme activities in differentiated or undifferentiated SH-SY5Y neuronal cells. Herein we concluded that TRPM7, TRPM8 and TRPV1 cation channels have pivotal effects on differentiation and MPP induced Parkinson's disease model in SH-SY5Y cells.
