HOTAIR and Parkinson disease: With “Parkinson’s disease” serving as the keyword, 14 PD-related lncRNAs were obtained from the LncRNADisease database, among which 4 lncRNAs (MALAT1, UCHL1-AS1, AK021630, and HOTAIR) were annotated to be implicated in the regulation of PD progression (Supplementary Table 1); however, the murine sequences of UCHL1-AS1 and AK021630 were not available in the array.
