en 28706608 <p>Background: Possible mechanisms of Alzheimer Disease (AD) such as inflammation and oxidative stresses in the brain led us to investigate potential AD therapeutics of <em>Melilotus officinalis</em>, an herbal extract, with possible role as an anti-inflammatory and anti-oxidant agent. Among different genes which had important role in Sporadic AD (SAD), three genes including<em> DAXX</em>, <em>NFkB</em> and <em>VEGF</em> have shown significant statistical diversity in the brains of Alzheimer patients.<br /> Methods: These genes were chosen to be investigated for neuroprotective effects of the extract by comparing the expression level in the hippocampus of Sporadic AD (SAD) rat model using quantitative polymerase chain reaction (qPCR) in the treated and untreated groups. In addition, therapeutic effects at the behavioral, learning and memory level by Morris Water Maze (MWM) test were investigated.<br /> Results: The results represented significant decreased expression in <em>Daxx</em>, <em>Nfkb</em> and <em>Vegf</em> genes in the SAD rat&rsquo;s model treated with the herbal extract compared to the Streptozotocin-induced (STZ-induced) rats. Furthermore, no significant changes were seen in swimming distance and time for finding the hidden platform in the herbal-treated compared to the STZ-induced group. In memory level, no significant changes were observed among treated and untreated groups.<br /> Conclusion: It seems that the herbal extract may have significant effect on Alzheimer-related gene expression changes but not on clinical levels.</p> Alzheimer disease, Gene expression, Herbal medicine 133 137 https://www.ajmb.org/En/Article.aspx?id=280 https://www.ajmb.org/PDF/En/FullText/280.pdf NiloofarBazazzadeganGenetics Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran930MarziehDehghan ShasaltanehLaboratory of Neuro-organic Chemistry, Institute of Biochemistry and Biophysics (IBB), University of Tehran, Tehran, Iran1007KioomarsSaliminejadReproductive Biotechnology Research Center, Avicenna Research Institute, ACECR, Tehran, Iran393KooroshKamaliReproductive Biotechnology Research Center, Avicenna Research Institute, ACECR, Tehran, Iran89MehdiBananGenetics Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran1152Hamid RezaKhorram KhorshidGenetics Research Center, University of Social Welfare and Rehabilitation Sciences, Tehran, Iran42
