Regarding the five axes supported by the miRNA expression in databases with ND information and ND studies, MEG3 (ENST00000398461)/hsa-let-7d-5p/ATF6B and MEG3 (ENST00000398461)/hsa-let-7 g-5p/ATF6B were supported by miTED, thus showing the upregulation of these miRNAs in PD. The gene discussed is MEG3; the disease is Parkinson disease.
