Cerebral palsy (CP) is one of the most common causes of motor disability in childhood, with complex and heterogeneous etiopathophysiology and clinical presentation. Understanding the metabolic processes associated with the disease may aid in the discovery of preventive measures and therapy. Tissue samples (caudate nucleus) were obtained from post-mortem CP cases ( = 9) and age- and gender-matched control subjects ( = 11). We employed a targeted metabolomics approach using both ¹H NMR and direct injection liquid chromatography-tandem mass spectrometry (DI/LC-MS/MS). We accurately identified and quantified 55 metabolites using ¹H NMR and 186 using DI/LC-MS/MS. Among the 222 detected metabolites, 27 showed significant concentration changes between CP cases and controls. Glycerophospholipids and urea were the most commonly selected metabolites used to develop predictive models capable of discriminating between CP and controls. Metabolomics enrichment analysis identified folate, propanoate, and androgen/estrogen metabolism as the top three significantly perturbed pathways. We report for the first time the metabolomic profiling of post-mortem brain tissue from patients who died from cerebral palsy. These findings could help to further investigate the complex etiopathophysiology of CP while identifying predictive, central biomarkers of CP.
脑性瘫痪(CP)是儿童期运动残疾最常见的病因之一,其病因病理生理学和临床表现复杂且具有异质性。了解与该疾病相关的代谢过程可能有助于发现预防措施和治疗方法。从死后的CP病例(n = 9)以及年龄和性别匹配的对照受试者(n = 11)获取组织样本(尾状核)。我们采用了靶向代谢组学方法,同时使用¹H NMR和直接进样液相色谱 - 串联质谱法(DI/LC-MS/MS)。我们使用¹H NMR准确鉴定和定量了55种代谢物,使用DI/LC-MS/MS鉴定和定量了186种代谢物。在检测到的222种代谢物中,27种在CP病例和对照之间显示出显著的浓度变化。甘油磷脂和尿素是用于建立能够区分CP和对照的预测模型的最常选择的代谢物。代谢组学富集分析确定叶酸、丙酸和雄激素/雌激素代谢为受干扰最显著的前三条途径。我们首次报告了死于脑性瘫痪患者死后脑组织的代谢组学图谱。这些发现有助于进一步研究CP复杂的病因病理生理学,同时识别CP的预测性中心生物标志物。
