Western blot results showed that compared with the HF + Exos + mimic-NC group, the protein expressions of PI3K, p-AKT, Ras, p-Erk1/2, BCL-2, SNAP-25, and VGluT-1 were significantly decreased, while the expressions of Cleaved Caspase-3 and Bax increased in the HF + Exos + miR-382-3p mimic group (Fig. 9G–I). The gene discussed is MAPK3; the disease is hydrops fetalis.
