BACKGROUND: Possible mechanisms of Alzheimer Disease (AD) such as inflammation and oxidative stresses in the brain led us to investigate potential AD therapeutics ofan 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 includingandhave shown significant statistical diversity in the brains of Alzheimer patients.
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.
RESULTS: The results represented significant decreased expression inandgenes in the SAD rat'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.
CONCLUSION: It seems that the herbal extract may have significant effect on Alzheimer-related gene expression changes but not on clinical levels.
