[PMID: 37773847 PMCID: PMC10545083 DOI: 10.1097/md.0000000000034700] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2023] [Accepted: 07/20/2023] [Indexed: 10/01/2023] Open
Abstract
The dysregulation of adenylate cyclase-associated protein 1 (CAP1) is associated with a variety of inflammatory conditions. Here, we aimed to assess the role of serum CAP1 protein in predicting acute myocardial infarction (AMI), and to explore its effect and mechanism in vascular endothelial cells injury. ELISA was utilized to detected CAP1 protein expression in serum from 70 patients with first-time AMI at 0, 6, 12, 24, 48 hours and 7 days of the onset of chest pain. Receiver operating characteristic (ROC) curve analysis was administered to analyze the diagnostic power of CAP1 for AMI. The CCK-8 and 5-BrdU assays were applied to measure cell proliferation and inflammation in a model of oxidized low-density lipoprotein (ox-LDL) induced human umbilical vein endothelial cells (HUVEC). Luciferase reporter gene assay and Western blotting were used to assess the activity of NF-κB pathway. Results showed that serum CAP1 protein expression was upregulated in patients with first-time AMI, its expression was highest at 12 hours of the onset of chest pain. CAP1 protein was positively associated with the levels of cTnI and ox-LDL. CAP1 showed a relatively high diagnostic accuracy in patients with first-time AMI compared with cTnI, and CAP1 combined with cTnI had superior diagnostic value than CAP1 and cTnI alone. The expression of CAP1 protein was increased in supernatants of ox-LDL induced HUVEC in a dose- and time-dependent manner. CAP1 inhibited cell proliferation but promoted inflammation, and induced the activation of NF-κB pathway in vitro. To sum up, increased serum CAP1 expression might serve as a novel diagnostic biomarker for patients with first-time AMI, the mechanism might be related to its induction of NF-κB pathway activation causing abnormal proliferation and inflammation and thus mediating vascular endothelial cell injury.

E3 Ubiquitin Ligase c-cbl Inhibits Microglia Activation After Chronic Constriction Injury. Neurochem Res 2018; 43:1631-1640.

Abstract
E3 ubiquitin ligase c-Caritas B cell lymphoma (c-cbl) is associated with negative regulation of receptor tyrosine kinases, signal transduction of antigens and cytokine receptors, and immune response. However, the expression and function of c-cbl in the regulation of neuropathic pain after chronic constriction injury (CCI) are unknown. In rat CCI model, c-cbl inhibited the activation of spinal cord microglia and the release of pro-inflammatory factors including tumor necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1β) and interleukin 6 (IL-6), which alleviated mechanical and heat pain through down-regulating extracellular signal-regulated kinase (ERK) pathway. Additionally, exogenous TNF-α inhibited c-cbl protein level vice versa. In the primary microglia transfected with c-cbl siRNA, when treated with TNF-α or TNF-α inhibitor, the corresponding secretion of IL-1β and IL-6 did not change. In summary, CCI down-regulated c-cbl expression and induced the activation of microglia, then activated microglia released inflammatory factors via ERK signaling to cause pain. Our data might supply a novel molecular target for the therapy of CCI-induced neuropathic pain.

Abstract
Astrocyte-elevated gene-1 (AEG-1), also known as metadherin (MTDH) and lysine-rich CEACAM1 coisolated (LYRIC), has emerged as an important oncogene that regulates key cellular processes including apoptosis, migration, invasion, proliferation, and differentiation. It was reported that AEG-1 enhanced breast cancer cells migration in a NF-κB-dependent manner. Also, AEG-1 contributed cell proliferation through the PI3K-Akt/cyclin pathway. Besides, AEG-1 is implicated in diverse physiological and pathological diseases of the central nervous system (CNS), such as brain tumors, neuroblastomas, neurodegeneration, and neuronal development. However, the role of AEG-1 in the process of peripheral nervous regeneration after injury remains virtually unknown. In this study, we investigated the spatiotemporal expression of AEG-1 in a rat sciatic nerve crush model. At its peak expression, AEG-1 was expressed mainly in Schwann cells of the distal sciatic nerve segment from injury, but had few colocalizations in axons. Besides, the peak expression of AEG-1 was in parallel with proliferating cell nuclear antigen (PCNA). In vitro, we detected the increased expression of AEG-1 during the process of tumor necrosis factor α (TNF-α)-induced Schwann cell proliferation. Meanwhile, interference of AEG-1 inhibited both proliferation and migration of Schwann cells. In conclusion, we speculated that AEG-1 is involved in biochemical and physiological responses after sciatic nerve crush (SNC).

Mol Neurobiol 2015; 53:6342-6354.

Abstract
SCY1-like 1-binding protein 1 (SCYL1BP1) is first identified as an interacting protein with SCYL1. Since SCYL1BP1 is a soluble protein with coiled-coil domains known to be relevant with transcriptional regulation, it has been found to activate the transcription of murine double minute 2 (MDM2) and participate in neurite outgrowth and regeneration. However, the role and mechanism of SCYL1BP1 in peripheral nerve system lesion and repair are still unknown. Here in vitro, our work demonstrated that SCYL1BP1 inhibited cAMP-induced primary Schwann cell differentiation and suppressed nerve growth factor-mediated neurite outgrowth in PC12 cells by enhancing the RhoA pathway. Furthermore, we found that pretreatment with a Rho kinase inhibitor Y-27632 resulted in partial rescue of Schwann cell differentiation and neurite outgrowth. In vivo experiments showed that SCYL1BP1 could also suppress nerve fiber regeneration. In conclusion, we speculated that SCYL1BP1 participated in Schwann cell (SC) differentiation and neurite outgrowth in the sciatic nerve after crush by regulating the RhoA pathway.

Abstract
BACKGROUND The ginsenoside Rb1 (Rb1) is the most abundant compound in the root of Panax ginseng. Recent studies have shown that Rb1 has a neuroprotective effect. However, the mechanisms underlying this effect are still unknown. METHODS We used stable isotope labeling with amino acids in cell culture, combined with quantitative mass spectrometry, to explore a potential protective mechanism of Rb1 in β-amyloid-treated neuronal cells. RESULTS A total of 1,231 proteins were commonly identified from three replicate experiments. Among these, 40 proteins were significantly changed in response to Rb1 pretreatment in β-amyloid-treated neuronal cells. Analysis of the functional enrichments and protein interactions of altered proteins revealed that actin cytoskeleton proteins might be linked to the regulatory mechanisms of Rb1. The CAP1, CAPZB, TOMM40, and DSTN proteins showed potential as molecular target proteins for the functional contribution of Rb1 in Alzheimer's disease (AD). CONCLUSION Our proteomic data may provide new insights into the protective mechanisms of Rb1 in AD.

Abstract
Poly(C)-binding proteins (PCBPs), also known as RNA-binding proteins, interact in a sequence-specific fashion with single-stranded poly(C). It was reported that PCBP2 contributed to gastric cancer proliferation and survival through miR-34a, and knockdown of PCBP2 inhibited glioma proliferation through inhibition of cell cycle progression. In addition, PCBP2 might play a critical role in the regulation of cortical neurons apoptosis induced by hypoxia or ischemia. Because of the essential role of PCBP2 in nervous system and cell growth, we investigated the spatiotemporal expression of PCBP2 in a rat sciatic nerve crush (SNC) model. We detected the upregulated expression of PCBP2 in Schwann cell after SNC. Besides, the peak expression of PCBP2 was in parallel with proliferation cell nuclear antigen. In vitro, we observed increased expression of PCBP2 during the process of TNF-α-induced Schwann cell proliferation. Specially, PCBP2-specific siRNA-transfected Schwann cell showed significantly decreased ability for proliferation. Together, all these data indicated that the change of PCBP2 protein expression was associated with Schwann cell proliferation after the trauma of the peripheral nervous system.

Abstract
Aminoacyl-tRNA synthetases (AminoARSs) are essential enzymes involved in acylating tRNA with amino acids. In addition to the typical functions of AminoARSs, various non-canonical functions have been reported, such as involvement in cellular regulatory processes and signal transduction. Here, to explore the cellular changes in sensory neurons after nerve injury, we evaluated AARS mRNA expression in rat dorsal root ganglia (DRG) neurons using AminoARS-specific primers. Of 20 AminoARSs, we found that expression of lysyl-tRNA synthetase (KARS) and glutaminyl-tRNA synthetase (QARS) was decreased in the DRG injured side. We observed decreased KARS and QARS expression in DRG neuronal cell bodies, but not in satellite cells. Therefore, we suggest the possibility that KARS and QARS may act as signaling molecules to transfer abnormal sensory signals to the spinal dorsal horn after peripheral nerve damage. Therefore, KARS and QARS may represent powerful pharmaceutical targets via control of their non-canonical functions.
