Altered offspring neurodevelopment in an L-NAME-induced preeclampsia rat model. Front Pediatr 2023; 11:1168173. [PMID: 37520045 PMCID: PMC10373593 DOI: 10.3389/fped.2023.1168173] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 07/03/2023] [Indexed: 08/01/2023] Open
Abstract
Introduction To investigate the mechanism underlying the increased risk of subsequent neurodevelopmental disorders in children born to mothers with preeclampsia, we evaluated the neurodevelopment of offspring of a preeclampsia rat model induced by the administration of N-nitro-L-arginine methyl ester (L-NAME) and identified unique protein signatures in the offspring cerebrospinal fluid. Methods Pregnant rats received an intraperitoneal injection of L-NAME (250 mg/kg/day) during gestational days 15-20 to establish a preeclampsia model. Behavioral experiments (negative geotaxis, open-field, rotarod treadmill, and active avoidance tests), immunohistochemistry [anti-neuronal nuclei (NeuN) staining in the hippocampal dentate gyrus and cerebral cortex on postnatal day 70], and proteome analysis of the cerebrospinal fluid on postnatal day 5 were performed on male offspring. Results Offspring of the preeclampsia dam exhibited increased growth restriction at birth (52.5%), but showed postnatal catch-up growth on postnatal day 14. Several behavioral abnormalities including motor development and vestibular function (negative geotaxis test: p < 0.01) in the neonatal period; motor coordination and learning skills (rotarod treadmill test: p = 0.01); and memory skills (active avoidance test: p < 0.01) in the juvenile period were observed. NeuN-positive cells in preeclampsia rats were significantly reduced in both the hippocampal dentate gyrus and cerebral cortex (p < 0.01, p < 0.01, respectively). Among the 1270 proteins in the cerebrospinal fluid identified using liquid chromatography-tandem mass spectrometry, 32 were differentially expressed. Principal component analysis showed that most cerebrospinal fluid samples achieved clear separation between preeclampsia and control rats. Pathway analysis revealed that differentially expressed proteins were associated with endoplasmic reticulum translocation, Rab proteins, and ribosomal proteins, which are involved in various nervous system disorders including autism spectrum disorders, schizophrenia, and Alzheimer's disease. Conclusion The offspring of the L-NAME-induced preeclampsia model rats exhibited key features of neurodevelopmental abnormalities on behavioral and pathological examinations similar to humans. We found altered cerebrospinal fluid protein profiling in this preeclampsia rat, and the unique protein signatures related to endoplasmic reticulum translocation, Rab proteins, and ribosomal proteins may be associated with subsequent adverse neurodevelopment in the offspring.

Identification of Novel Biomarkers of Spinal Muscular Atrophy and Therapeutic Response by Proteomic and Metabolomic Profiling of Human Biological Fluid Samples. Biomedicines 2023; 11:1254. [PMID: 37238925 PMCID: PMC10215459 DOI: 10.3390/biomedicines11051254] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 04/16/2023] [Accepted: 04/20/2023] [Indexed: 05/28/2023] Open
Abstract
Spinal muscular atrophy (SMA) is a neuromuscular disease resulting from mutations or deletions in SMN1 that lead to progressive death of alpha motor neurons, ultimately leading to severe muscle weakness and atrophy, as well as premature death in the absence of treatment. Recent approval of SMN-increasing medications as SMA therapy has altered the natural course of the disease. Thus, accurate biomarkers are needed to predict SMA severity, prognosis, drug response, and overall treatment efficacy. This article reviews novel non-targeted omics strategies that could become useful clinical tools for patients with SMA. Proteomics and metabolomics can provide insights into molecular events underlying disease progression and treatment response. High-throughput omics data have shown that untreated SMA patients have different profiles than controls. In addition, patients who clinically improved after treatment have a different profile than those who did not. These results provide a glimpse on potential markers that could assist in identifying therapy responders, in tracing the course of the disease, and in predicting its outcome. These studies have been restricted by the limited number of patients, but the approaches are feasible and can unravel severity-specific neuro-proteomic and metabolic SMA signatures.

Abstract
Background:
Preeclampsia (PE) is a common pregnancy-specific disease with potential adverse maternal and neonatal outcomes.
Objective:
We aimed to estimate proteomic profiles of serum-derived exosomes obtained from PE offspring with bioinformatics methods.
Method:
Serum samples were collected from 12 h, 24 h, and 72 h newborns delivered by preeclamptic and normal pregnant women. Exosomes were extracted, and the concentration and size distribution were determined. The exosome surface markers CD9, CD63, CD81, and TSG101, were assayed by Western blot. The exosome proteins were screened by quantitative proteomics with tandem mass tag (TMT). All the identified proteins were subjected to the Weighted Gene Co-Expression Network Analysis (WGCNA), GO function, and KEGG pathway analysis. A protein-protein interaction network (PPI) was used to extract hub proteins through the Cytohubba plugin of Cytoscape
Results:
The extracted exosomes were round or oval vesicular structures at a 100-200 nm concentration, and the size distribution was standard and uniform. Exosome surface markers CD9, CD63, and CD81 were detected, and TSG101 was not detected. A total of 450 expressed proteins were selected, and 444 proteins were mapped with gene names. A blue module with 66 proteins highly correlated with phenotype at 12 h. Functional analyses revealed that module proteins were mainly enriched in extracellular matrix. The top 10 selected hub proteins were identified as hub proteins, including COL6A2, HSPG2, COL4A1, COL3A1, etc.
Conclusion:
Our study provides important information for exploring molecular mechanisms of preeclampsia and potential biomarkers for future diagnosis and treatment in the clinic.
