Figure 2 Expression levels of APP gene in brain tissues of AD-induced male rats treated with Hyphaene thebaica extract with/or after AD induction. Data are presented as mean±SEM. a, b, c: followed by different superscripts are significantly different (P≤0.05). a, b, c: percentage values within column with unlike superscript letters were significantly different (aP<0.001, bP<0.01, c, dP<0.05). AD, Alzheimer’s disease; APP, amyloid precursor protein.
