Abstract
Traumatic brain injury (TBI) poses a serious threat to human health. TBI has a high mortality rate, resulting in a great burden on the affected individual's family as well as society as a whole. The incidence of craniocerebral fractures continues to rise as both the economy and transportation options grow, making it imperative that the mortality and disability rate of craniocerebral trauma be reduced. Nur77 is a transcription factor of the nuclear receptor superfamily. Following stimulation of extracellular apoptosis, Nur77 is involved in a variety of diseases as a powerful pro-apoptotic molecule. Here, we determined the effect and mechanism of Nur77 in TBI-induced nerve cell apoptosis in vitro and in vivo. We found that Nur77 and Bcl-2 protein expression increased as nerve cell apoptosis increased in TBI tissues. Furthermore, inhibition of Nur77 improved nerve cell injury by regulation of Bcl-2 and downstream pathways in vitro and in vivo.
