ABSTRACT
Transgenic animals are those in which recombinant DNA technology is used to remove a gene or a specific part of DNA with exogenous DNA, which is hereditable and can be expressed stably. Transgenic rodent technology, first demonstrated by Gordon in 1980,opened the door to the next step in biotechnology and gene regulation, which has been used to reproduce or mimic a part of a human disease in a complex cellular environment by creating in vivo models with germ line transmission of the introduced genetic regulatory elements. Animal models for drug discovery are developing increasingly, which is promoting the research and development new drugs greatly. The use and development of transgenic animals in pharmacological research is reviewed in this article.
ABSTRACT
Valproate (VPA) has long been used for the treatment of bipolar mood disorder. VPA is effective in control of mania and depression. Recent studies have demonstrated that VPA has profound neuroprotective effects in against various apoptotic stimuli. Moreover, VPA can promote neurogenesis, neuronal proliferation and differentiation. Although intensive research has been dedicated to VPA′s neuroprotection, the molecular mechanisms by which VPA protects neurons are still not fully understood. In this paper, recent progresses in the study of VPA′s neuroprotection and underlying mechanism are reviewed.
