Among the mRNAs targets of miR-10b*, miR-29a-3p, and miR-130b-3p, which were analyzed in plasma from VaD and AD patients and NCs (i.e., BACE1, CCT5, EDN1, GSK3B, ITPR1, LPL, NAV3, and ZEB1), only ZEB1 (target of miR-130b-3p) was detected; however, its plasma levels were not different among the individuals of the three cohorts analyzed. This evidence concerns the gene BACE1 and Alzheimer disease.
