Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder caused by expansion of polyglutamine at the N-terminus of the huntingtin protein. Striatal medium spiny neurons (MSN) are the primary targets of HD pathology. In our study, a cellular model of HD was based on the human neuroblastoma cells SK-N-SH transfected with plasmid for expression of the mutant huntingtin protein Htt138Q. Expression of Htt138Q increased store-dependent calcium entry into SK-N-SH cells. EVP4593 reversibly blocked the abnormal store-dependent response, probably generated by the channels incorporating TRPC1 ( transient receptor potential canonical 1) subunit.
