NF-κB 在糖尿病性神经痛中的作用及机制
Role of NF-κB in diabetic neuropathy
摘要
Abstract
AIM: To investigate the role of NF-κB in diabetic neuropathy.METHODS: The diabetic rats were induced by intraperitoneal injection of streptozocin ( STZ) .The pain behavior test was used to detect the mechanical and thermal withdraw threshold of the rats’ bilateral hind paws.The protein levels of p-NF-κB and t-NF-κB in the rats’ L4 and L5 dorsal root ganglions ( DRG) were determined by Western blotting.The expression of Nav1.7 in DRG of diabetic neuropathy rats with or without NF-κB inhibitor PDTC was detected by the method of immunohistochemistry.RESULTS:The mechanical and thermal withdraw threshold of bilateral hind paws in the diabetic rats was decreased from 4 weeks to 12 weeks after injection of STZ.The protein levels of p-NF-κB in L4 and L5 DRG were significantly increased in the rats with diabetic neuropathy.Intrathecal administration of NF-κB inhibitor PDTC attenuated the increase in p-NF-κB and Nav1.7 in L4 and L5 DRG.Pain behaviors were also alleviated by PDTC.CONCLUSION:The increase in p-NF-κB is closely rela-ted to the generation of diabetic neuropathy.Inhibition of NF-κB blocks pain behaviors and the over-expression of Nav1.7 in DRG.关键词
