Bex1 attenuates neuronal apoptosis in rat intracerebral hemorrhage model

In this study, the roles of Bex1 were explored in the pathophysiology of ICH. Western blot, immunohistochemistry, and immunofluorescence showed that obvious up-regulation of Bex1 in neurons adjacent to the hematoma after ICH. Furthermore, the increase of Bex1 expression was accompanied by the enhanced expression of Bax and active caspase-3, and decreased expression of B-cell lymphoma 2 (Bcl-2) following ICH. The in vitro study using Bex1 siRNA transfection in hemin-exposed PC12 cells suggested that Bex1 exerted anti-apoptotic function. Therefore, Bex1 may play the neuronal anti-apoptosis role following ICH, implying a novel molecular target for the therapy of ICH.
