HIF-1α/microRNA-128-3p axis protects hippocampal neurons from apoptosis via the Axin1-mediated Wnt/β-catenin signaling pathway in Parkinson’s disease models

Figure 6. The expression pattern of HIF-1α/miR-128-3p/Axin1 and the Wnt/β-catenin signaling pathway-related proteins (β-catenin, cyclin D1 and c-met) in hippocampal neurons of the MPTP-lesioned mouse model of PD after transfection with si-Hif1a or oe-Hif1a. (A) The miR-128-3p expression and mRNA levels of Hif1a, Axin1, Ctnnb1, Ccnd1, and Met in hippocampal neurons of the MPTP-lesioned mouse model of PD determined by RT-qPCR. (B) The protein band patterns and the protein levels of HIF-1α, AXIN1, β-catenin, cyclin D1, and c-met normalized to β-actin in hippocampal neurons of the MPTP-lesioned mouse model of PD determined by western blot analysis. (C) The localization of β-catenin protein in hippocampal tissues of the MPTP-lesioned mouse model of PD detected by the immunofluorescence assay (scale bar = 25 μm). * p < 0.05 vs. the NC group (hippocampal neurons of the MPTP-lesioned mouse model of PD treated with NC plasmids). N = 10.
