Thus, the MEG3 (ENST00000398461)/hsa-let-7d-5p/ATF6B, AC092687.3 (ENST0000606907)/hsa-let-7e-5p/SREBF2, AC092687.3 (ENST0000606907)/hsa-let-7e-5p/FNIP1, AC092687.3 (ENST0000606907)/hsa-let-7e-5p/PMAIP1, and SDCBP2-AS1 (ENST00000446423)/ hsa-miR-101-3p/MAPK6 axes would be key in controlling processes related to AD and PD, according to the GSE48552, GSE46131, GSE46579, and GSE155700 studies. This evidence concerns the gene FNIP1 and Parkinson disease.
