摘要
人们越来越关注精氨酸代谢在精神分裂症中的病理生理作用,尤其是与调节内源性信使一氧化氮(NO)有关的作用。与一氧化氮不同,特定精氨酸代谢物是稳定的,对其进行评估可为了解一氧化氮调控酶(如二甲基精氨酸二甲基氨水解酶同工酶 1(DDAH1)和精氨酸酶)提供有用的信息。我们通过对精神分裂症患者群体中与 DDAH1、精氨酸酶和 NO 合成相关的精氨酸代谢物 [精氨酸、瓜氨酸、不对称二甲基精氨酸 (ADMA)、对称二甲基精氨酸 (SDMA)、二甲胺和鸟氨酸] 的循环浓度进行系统回顾和荟萃分析,研究了精氨酸代谢组学在精神分裂症中的作用。我们检索了 PubMed、Scopus 和 Web of Science 从开始到 2023 年 5 月 31 日有关精神分裂症患者和健康对照组精氨酸代谢物的研究。分析研究的 JBI 关键评估清单和 GRADE 分别用于评估偏倚风险和证据的确定性(PROSPERO 注册号:CRD42023433000)。共确定了 21 项研究用于分析。精氨酸、瓜氨酸和 SDMA 在组间无明显差异。相比之下,精神分裂症患者的 ADMA(DDAH1 底物,标准均值差异,SMD = 1.23,95% CI 0.86-1.61,p
A systematic review and meta-analysis of nitric oxide-associated arginine metabolites in schizophrenia.
There is increasing interest in the pathophysiological role of arginine metabolism in schizophrenia, particularly in relation to the modulation of the endogenous messenger nitric oxide (NO). The assessment of specific arginine metabolites that, unlike NO, are stable can provide useful insights into NO regulatory enzymes such as isoform 1 of dimethylarginine dimethylaminohydrolase (DDAH1) and arginase. We investigated the role of arginine metabolomics in schizophrenia by conducting a systematic review and meta-analysis of the circulating concentrations of arginine metabolites associated with DDAH1, arginase, and NO synthesis [arginine, citrulline, asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), dimethylamine, and ornithine] in this patient group. We searched PubMed, Scopus, and Web of Science from inception to the 31st of May 2023 for studies investigating arginine metabolites in patients with schizophrenia and healthy controls. The JBI Critical Appraisal Checklist for analytical studies and GRADE were used to assess the risk of bias and the certainty of evidence, respectively (PROSPERO registration number: CRD42023433000). Twenty-one studies were identified for analysis. There were no significant between-group differences in arginine, citrulline, and SDMA. By contrast, patients with schizophrenia had significantly higher ADMA (DDAH1 substrate, standard mean difference, SMD = 1.23, 95% CI 0.86-1.61, p < 0.001; moderate certainty of evidence), dimethylamine (DDAH1 product, SMD = 0.47, 95% CI 0.24-0.70, p < 0.001; very low certainty of evidence), and ornithine concentrations (arginase product, SMD = 0.32, 95% CI 0.16-0.49, p < 0.001; low certainty of evidence). In subgroup analysis, the pooled SMD for ornithine was significantly different in studies of untreated, but not treated, patients. Our study suggests that DDAH1 and arginase are dysregulated in schizophrenia. Further studies are warranted to investigate the expression/activity of these enzymes in the brain of patients with schizophrenia and the effects of targeted treatments.
期刊介绍:
Psychiatry has suffered tremendously by the limited translational pipeline. Nobel laureate Julius Axelrod''s discovery in 1961 of monoamine reuptake by pre-synaptic neurons still forms the basis of contemporary antidepressant treatment. There is a grievous gap between the explosion of knowledge in neuroscience and conceptually novel treatments for our patients. Translational Psychiatry bridges this gap by fostering and highlighting the pathway from discovery to clinical applications, healthcare and global health. We view translation broadly as the full spectrum of work that marks the pathway from discovery to global health, inclusive. The steps of translation that are within the scope of Translational Psychiatry include (i) fundamental discovery, (ii) bench to bedside, (iii) bedside to clinical applications (clinical trials), (iv) translation to policy and health care guidelines, (v) assessment of health policy and usage, and (vi) global health. All areas of medical research, including — but not restricted to — molecular biology, genetics, pharmacology, imaging and epidemiology are welcome as they contribute to enhance the field of translational psychiatry.
