Anti-depressant Mechanisms of Wuling Jun Powder by Gene Microarray Analysis / 中国康复理论与实践

ABSTRACT

@#ObjectiveTo explore the possible mechanisms of Wuling Jun Power by the DNA microarray technique.MethodsAn experimental depression model was established by exposing the mouse to a chronic mild stress procedure. The total RNA was extracted reverse-transcripted and hybrided to the mouse 1-2 cDNA microarray (Clontech). The difference of expression profiles between control model, Wuling Jun powder and fluoxetine-treated groups were analyzed by the Image 2-1 Software.Results130 genes were significantly altered in stress group compared with the control groups. Among them, 116 genes were up-regulated and 14 genes were down-regulated. Meanwhile, 85 genes significantly changed in the Wuling Jun powder treated group with 34 genes up-regulated and 51 genes down-regulated compared with the model groups. For the Fluoxetine-treated group, 133 genes significantly changed with 35 genes up-regulated and 98 genes down-regulated compared with the model groups. These genes were associated with many aspects of life including receptor activity, protein kinases, inflammatory factors, transferrin, neurogenesis and so on.ConclusionMultiple genes were affected by the stress exposure. Altered changes of some genes were normalized by Wuling Jun powder and Fluoxetine treatment. In general, the mechanisms of Wuling Jun powder and Fluoxetine are similar, but also with minor difference.
