MALAT1 and Parkinson disease: As mentioned in Introduction section, it doesn’t deny that other lncRNAs such as NEAT1, HOTAIR, SNHG1, MALAT1 and p21 and other miRNAs such as miR-128, miR-7, miR-27a/27b and miR-200a were involved in PD progression, our study mainly focused the relationship between XIST and miR-199a-3p and the networks of other lncRNAs and miRNAs will be worthy of further investigation in our future study.
