WB
e Expression of PAI-1 in BMMSCs was significantly increased following treatment with any concentration of GC, as shown by qRT-PCR and western blotting.
WB
b Expression of PAI-1 in VSMCs was increased by GC treatment and by GB-Exo treatment, as shown by qRT-PCR and c western blotting results.e qRT-PCR and f western blotting also demonstrated that overexpressed PAI-1 was detected in GC-treated and GB-Exo groups in VECs. In particular, GB-Exo groups exhibited dramatically upregulated PAI-1 expression in VECs.
WB
f qRT-PCR results demonstrated that the expression levels of PAI-1 were reduced by treatment with miR-133b-3p mimics and increased by treatment with an miR-133b-3p inhibitor in VECs, which was also verified by western blotting (g).
