*3.2. Estrogen Receptor Alpha (ER*α*) Protein Expression*

Figure 2 shows that Aβ (25–35) alone markedly reduced the protein expression of ERα (*p* < 0.05), whereas pretreatments of Eq and E2 significantly attenuated the decreased protein expressions of ERα induced by Aβ (25–35) (*p* < 0.05). However, in the presence of ICI-182,780, the effects of the Eq and E2 pretreatments on ERα expression were significantly blocked (*p* < 0.05).
