目的
2
探讨晚期糖基化终末产物受体(RAGE)-信号传导和转录激活因子3(STAT3)信号通路介导递质剥夺诱导纹状小体/基质神经元线粒体损伤的分子机制。
方法
2
使用6-OHDA诱导的多巴胺剥夺帕金森病(PD)大鼠模型,予以RAGE阻滞剂FPS-ZM1处理。通过免疫组织化学、透射电镜(TEM)、蛋白质免疫印迹(Western blot)和qRT-PCR等技术,观测纹状小体/基质微环路中RAGE表达、STAT3分子的变化及线粒体超微结构。
结果
2
PD模型组纹状小体/基质组构内RAGE阳性结构密度显著高于对照组(
P
<0.05),Western blot显示RAGE蛋白表达水平显著上调。免疫组化和荧光双标显示STAT3在纹状体神经元中广泛表达,神经元(NeuN)-STAT3双标记细胞在PD模型组显著增多(
P
<0.05);Western blot和qRT-PCR均证实PD模型组STAT3蛋白及mRNA水平显著升高(
P
<0.05)。TEM显示PD模型组神经元线粒体密度显著降低(
P
<0.05),线粒体截面积增大(
P
<0.05),线粒体嵴数量减少(
P
<0.05),伴有嵴膜断裂、外膜破损等病理改变,然而注射FPS-ZM1可逆转这些变化。
结论
2
RAGE信号通路关键位点转录因子STAT3参与纹状小体/基质组构神经元线粒体结构紊乱的病理机制,纹状小体/基质组构为整体探查纹状体神经元线粒体损伤及PD的发病机制研究提供了新的靶点。
Objective
2
To investigate the molecular mechanisms by which the receptor for advanced glycation end products(RAGE)-signal transducer and activator of transcription 3(STAT3) signaling pathway mediates mitochondrial injury in striosome/matrix compartment neurons under dopaminergic depletion in Parkinson's disease (PD).
Methods
2
A 6-hydroxydopamine (6-OHDA)-induced rat model of PD was established and treated with the RAGE inhibitor FPS-ZM1. Immunohistochemistry, double immunofluorescence staining, transmission electron microscopy (TEM), Western blotting, and quantitative real-time PCR (qRT-PCR) were performed to evaluate RAGE and STAT3 expression as well as mitochondrial ultrastructure alterations in the striosome/matrix compartment.
Results
2
The density of RAGE-positive structures and the protein expression level of RAGE in the striosome/matrix compartment were significantly increased in PD rats compared with controls (
P
<
0.05). Immunohistochemical and double immunofluorescence analyses demonstrated widespread STAT3 expression in striatal neurons, while the number of NeuN/STAT3 double-positive cells was significantly elevated in the PD group (
P
<
0.05). Western blotting and qRT-PCR further confirmed significant upregulation of STAT3 protein and mRNA expression in PD rats (
P
<
0.05). TEM analysis revealed marked mitochondrial abnormalities in PD neurons, including reduced mitochondrial density, enlarged mitochondrial area, decreased cristae number, cristae membrane disruption, and outer membrane damage (all
P
<
0.05). Notably, FPS-ZM1 treatment partially reversed these mitochondrial ultrastructural alterations.
Conclusion
2
Activation of the RAGE-STAT3 signaling pathway contributes to mitochondrial structural disruption in striosome/matrix compartment neurons in PD. These findings suggest that the striosome/matrix compartment may represent a novel pathological target for investigating mitochondrial dysfunction and neurodegeneration in PD.
