HOTAIRM1 and Parkinson disease: Fan et al. (2019) also found that four differentially expressed level of lncRNAs (AC131056.3-001, HOTAIRM1, lnc-MOK-6:1 and RF01976.1-201) were up-regulated in leukocytes from patients of PD, and dysregulation of lncRNAs (AC131056.3-001 and HOTAIRM1) could lead to apoptosis of dopamine neurons [79].
