Figure 7From: Dietary supplementation of soy germ phytoestrogens or estradiol improves spatial memory performance and increases gene expression of BDNF, TrkB receptor and synaptic factors in ovariectomized ratsThe gene expression of sypnatic formation proteins in the hippocampal tissue of ovariectomized rats. The gene expression of sypnatic formation proteins in the hippocampal tissue of ovariectomized rats fed on the control diet (white), or the control diet supplemented with 0.4 g/kg phytoestrogens (white spotted), 1.6 g/kg phytoestrogens (grey spotted), or 0.15 g/kg 17βestradiol (dark grey). The upper panel showed the PCR image and the lower panel presented the levels of mRNA of sypnatic formation proteins expressed as the ratio to the internal control of GADPH mRNA. The mean values labelled with different letters differed significantly (p < 0.05).Back to article page
