Non-coding RNA Neat1 and Abhd11os expressions are dysregulated in medium spiny neurons of Huntington disease model mice

•The expression of many ncRNAs was dysregulated in R6/2 HD model mouse brains.•Abhd11os, Neat1-1 and Neat1-2 expressions were downregulated in R6/2.•ViewRNA ISH provided precise detection of ncRNAs with low expression levels. Huntington Disease (HD) is a neurodegenerative disorder caused by expanded CAG repeats in the exon1 of huntingtin gene (HTT). The mutant HTT affects the transcriptional profile of neurons by disrupting the activities of transcriptional machinery and alters expression of many genes. In this study, we identified dysregulated non-coding RNAs (ncRNAs) in medium spiny neurons of 4-week-old HD model mouse. Also, we observed the intracellular localizations of Abhd11os and Neat1 ncRNAs by ViewRNA in situ hybridization, which could provide more precise detection, suggesting that it is a useful method to investigate the expression changes of genes with low expression levels.
