Abstract/OtherAbstract:
C-terminal binding protein 2 (CtBP2), as a transcriptional repressor, plays an essential role in development and tumorigenesis. However, its distribution and function in peripheral system lesion and repair are still unknown. Here, we investigated the spatiotemporal expression of CtBP2 in rat sciatic nerve crush model. Western blot analysis revealed that CtBP2 was expressed in normal sciatic nerve. It gradually decreased, reached minimal levels at 7 days after crush, and then returned to the normal level at 4 weeks. We observed that CtBP2 is mainly expressed in Schwann cells (SCs). In vitro, we induced SC differentiation via cyclic adenosine monophosphate (cAMP) and found that CtBP2 expression was downregulated during the process of differentiation. CtBP2-specific siRNA inhibited the cAMP-induced expression of the immature SC marker P75(NTR), and exogenous CtBP2 expression upregulated the expression of P75(NTR). Taken together, we hypothesized that peripheral nerve crush-induced downregulation of CtBP2 in the sciatic nerve was associated with SC differentiation, and CtBP2 likely played an important role in peripheral nerve injury and regeneration.
