[PMID: 38966092 PMCID: PMC11221885 DOI: 10.1093/toxres/tfae100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 05/20/2024] [Accepted: 06/26/2024] [Indexed: 07/06/2024] Open
Abstract
Background Postoperative cognitive dysfunction (POCD) is a generally recognized complication experienced by patients who receive anesthesia during surgery. Sevoflurane, the most commonly used inhaled anesthetic, has been shown to trigger neuroinflammation that promotes to POCD. Objective This study examined the pathological mechanism by which sevoflurane causes neuroinflammation, participating in POCD. Methods To establish a neurocyte injury model, the human neuroblastoma cell lines SH-SY5Y and SK-N-SH were treated with sevoflurane. Cell viability was determined using 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assays. The reactive oxygen species (ROS) level was evaluated by DCFH-DA assays. A lactate dehydrogenase (LDH) Cytotoxicity Assay Kit was used to measure LDH levels. Inflammatory cytokine levels were measured using enzyme-linked immunosorbent assay assays. Gene expression densities and protein abundance were evaluated using quantitative real-time polymerase chain reaction (qRT-PCR) or western blotting. The interaction between YTHDF1 and dual specific phosphatase 6 (DUSP6) was validated using RNA immunoprecipitation (RIP)-qPCR and methylated RIP (MeRIP)-qPCR assays. Flow cytometry was performed to determine apoptosis. Results Sevoflurane promoted apoptosis, oxidative stress, and neuroinflammation and repressed the expression levels of YTHDF1 and DUSP6. Furthermore, YTHDF1 overexpression reversed sevoflurane-induced neuroinflammation in neurocytes. DUSP6 overexpression could alleviate the neuroinflammation induced by sevoflurane via regulating the extracellular signal-regulated kinase (ERK)1/2 signaling pathway. Moreover, YTHDF1 enhanced DUSP6 expression. Conclusion Sevoflurane-stimulated neuroinflammation by regulating DUSP6 via YTHDF1. Sevoflurane promoted neuroinflammation by regulating DUSP6 via YTHDF1 in an in vitro model of POCD.

Abstract
The renal interstitial fibrosis contributes to the progression and deterioration of diabetic nephropathy (DN). Long noncoding RNA taurine-up-regulated gene 1 (TUG1) in kidneys may be down-regulated by hyperglycemia. We aim to explore its role in tubular fibrosis caused by high glucose and the possible target genes of TUG1. In this study, a streptozocin-induced accelerated DN mouse model and a high glucose-stimulated HK-2 cells model was established to evaluate TUG1 expression. Potential targets of TUG1 were analyzed by online tools and confirmed by luciferase assay. A rescue experiment and gene silencing assay were used to investigate whether TUG1 plays its regulation role via miR-145-5p/dual-specificity phosphatase 6 (DUSP6) in HK2 cells. The effects of TUG1 on inflammation and fibrosis in high glucose treated tubular cells were evaluated by in vitro study, as well as in vivo DN mice model through AAV-TUG1 delivery. Results showed TUG1was downregulated in HK2 cells incubated with high glucose while miR-145-5p was upregulated. Overexpression of TUG1 alleviated renal injury by suppressing inflammation and fibrosis in vivo. Overexpression of TUG1 inhibited HK-2 cell fibrosis and relieved the inflammation. A mechanism study demonstrated that TUG1 directly sponged to miR-145-5p, and DUSP6 was identified as a target downstream of miR-145-5p. In addition, miR-145-5 overexpression and DUSP6 inhibition countervailed the impacts of TUG1. Our findings revealed that TUG1 overexpression alleviates kidney injury in DN mice and decreases the inflammatory response and fibrosis of high glucose-stimulated HK-2 cells via miR-145-5p/DUSP6 axis.

[PMID: 37706594 DOI: 10.1002/jbt.23503] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 07/10/2023] [Accepted: 07/31/2023] [Indexed: 09/15/2023]
Abstract
Diabetic kidney disease (DKD) is a devastating complication of diabetes mellitus (DM) and is the most prevalent chronic kidney disease (CKD). Poricoic acid A (PAA), a component isolated from Traditional Chinese Medicine (TCM) Poria cocos, has hypoglycaemic and anti-fibrosis effects. However, the role of PAA in DKD remains largely unclear. To mimics an in vitro model of DKD, the mouse podocyte MPC5 cells were treated with high glucose (25 mM; HG) for 24 h. CCK-8 and flow cytometry assays were conducted for assessing MPC5 cell viability and apoptosis. Meanwhile, streptozotocin (STZ) was used to induce experimental DKD in mice by intraperitoneal injection. PAA notably inhibited the apoptosis and inflammation, reduced the generation of ROS, and elevated the MMP level in HG-treated MPC5 cells. Moreover, PAA obviously reduced blood glucose and urine protein levels, inhibited renal fibrosis in DKD mice. Meanwhile, PAA markedly increased LC3 and ATG5 levels and declined p62 and FUNDC1 levels in HG-treated MPC5 cells and in the kidney tissues of DKD mice, leading to the activation of cell mitophagy. Furthermore, the downregulation of FUNDC1 also inhibited apoptosis, inflammation, and promoted mitophagy in HG-treated MPC5 cells. As expected, the knockdown of FUNDC1 further enhanced the protective role of PAA in MPC5 cells following HG treatment, indicating that induction of mitophagy could attenuate podocyte injury. Collectively, PAA could exert beneficial effects on podocyte injury in DKD by promoting mitophagy via downregulating FUNDC1. These findings suggested that PAA may have great potential in alleviating kidney injury in DKD.

Abstract
Minichromosome maintenance 6 (MCM6) has been implicated in the progression of various malignant tumors; however, its exact physiological function in kidney diseases remains unclear. Here, we demonstrated that MCM6 levels showed a significant increase in the proximal tubular cells during progressive renal fibrosis in two unrelated in vivo fibrotic models, including unilateral ureteral obstruction (UUO) and unilateral ischemia-reperfusion injury (UIRI). Depletion of MCM6 aggravated partial epithelial-mesenchymal transition, extracellular matrix accumulation, and myofibroblast activation in the kidneys of UUO or UIRI mice. Conversely, overexpression of MCM6 promoted the recovery of E-cadherin and retarded UUO- or UIRI-induced renal fibrosis. In addition, DUSP6 expression substantially decreased in fibrotic kidneys, and it might be involved in MCM6-induced renal fibrosis by regulating the activation of ERK/GSK-3β/Snail1 signaling. In conclusion, our results highlight the significance of MCM6 in renal fibrosis, providing a potential therapeutic target for patients with chronic kidney disease.

Abstract
Diabetic nephropathy (DN) is a common severe microvascular complication of diabetes mellitus, and podocyte damage occurs in the early stages of DN. The urine of patients with various types of glomerular disease presents increased levels of ADAM metallopeptidase domain 10 (ADAM10). The present study aimed to explore the role of ADAM10 in podocyte damage. Therefore, the expression of ADAM10 in high glucose (HG)-stimulated podocytes was measured by reverse transcription-qPCR and western blot. Moreover, the effects of ADAM10 knockdown on podocyte inflammation and apoptosis were determined by ELISA, western blot and TUNEL assay after confirming the efficacy of cell transfection. Subsequently, the effects of ADAM10 knockdown on the MAPK pathway and pyroptosis were assessed by western blot. Through performing the aforementioned experiments, the role of the MAPK pathway in the regulatory effects of ADAM10 was then investigated by pretreating podocytes with pathway agonists. ADAM10 expression was upregulated in HG-stimulated podocytes, while ADAM10 knockdown suppressed inflammation, apoptosis and pyroptosis of HG-stimulated podocytes and inhibited the activation of the MAPK signaling pathway. However, when podocytes were pretreated with pathway agonists (LM22B-10 or p79350), the aforementioned effects of ADAM10 knockdown were suppressed. The present study demonstrated that ADAM10 knockdown suppressed the inflammation, apoptosis and pyroptosis of HG-stimulated podocytes by blocking the MAPK signaling pathway.

Abstract
Mycophenolate Mofetil (MMF) has an established role as a therapeutic agent in childhood nephrotic syndrome. While other immunosuppressants have been shown to positively affect podocytes, direct effects of MMF on podocytes remain largely unknown. The present study examines the effects of MMF's active component Mycophenolic Acid (MPA) on the transcriptome of podocytes and investigates its biological significance. We performed transcriptomics in cultured murine podocytes exposed to MPA to generate hypotheses on podocyte-specific effects of MPA. Accordingly, we further analyzed biological MPA effects on actin cytoskeleton morphology after treatment with bovine serum albumin (BSA) by immunofluorescence staining, as well as on cell survival following exposure to TNF-α and cycloheximide by neutral red assay. MPA treatment significantly (adjusted p < 0.05) affected expression of 351 genes in podocytes. Gene Ontology term enrichment analysis particularly clustered terms related to actin and inflammation-related cell death. Indeed, quantification of the actin cytoskeleton of BSA treated podocytes revealed a significant increase of thickness and number of actin filaments after treatment with MPA. Further, MPA significantly reduced TNFα and cycloheximide induced cell death. MPA has a substantial effect on the transcriptome of podocytes in vitro, particularly including functional clusters related to non-immune cell dependent mechanisms. This may provide a molecular basis for direct beneficial effects of MPA on the structural integrity and survival of podocytes under pro-inflammatory conditions.

Abstract
Tuberculosis (TB) is a zoonotic infectious disease caused by Mycobacterium tuberculosis (Mtb). Apoptosis and necrosis caused by the interaction between the host and the pathogen, as well as the host's inflammatory response, play an important role in the pathogenesis of TB. Dual-specificity phosphatase 1 (DUSP1) plays a vital role in regulating the host immune responses. However, the role of DUSP1 in the regulation of THP-1 macrophage apoptosis induced by attenuated Mycobacterium bovis Bacillus Calmette-Guérin (BCG) infection remains unclear. In the present study, we report that infection with BCG significantly induces macrophage apoptosis and induces the production of DUSP1, TNF-α and IL-1β. DUSP1 knockdown significantly inhibited BCG-induced macrophage apoptosis and activation of MAPKs/NF-κB signaling pathway. In addition, DUSP1 knockdown suppressed BCG-induced inflammation in vivo. Taken together, this study demonstrates that DUSP1, as a regulator of MAPKs/NF-κB signaling pathway, plays a novel role in BCG-induced macrophage apoptosis and inflammatory response.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the main cause of COVID-19, causing hundreds of millions of confirmed cases and more than 18.2 million deaths worldwide. Acute kidney injury (AKI) is a common complication of COVID-19 that leads to an increase in mortality, especially in intensive care unit (ICU) settings, and chronic kidney disease (CKD) is a high risk factor for COVID-19 and its related mortality. However, the underlying molecular mechanisms among AKI, CKD, and COVID-19 are unclear. Therefore, transcriptome analysis was performed to examine common pathways and molecular biomarkers for AKI, CKD, and COVID-19 in an attempt to understand the association of SARS-CoV-2 infection with AKI and CKD. Three RNA-seq datasets (GSE147507, GSE1563, and GSE66494) from the GEO database were used to detect differentially expressed genes (DEGs) for COVID-19 with AKI and CKD to search for shared pathways and candidate targets. A total of 17 common DEGs were confirmed, and their biological functions and signaling pathways were characterized by enrichment analysis. MAPK signaling, the structural pathway of interleukin 1 (IL-1), and the Toll-like receptor pathway appear to be involved in the occurrence of these diseases. Hub genes identified from the protein-protein interaction (PPI) network, including DUSP6, BHLHE40, RASGRP1, and TAB2, are potential therapeutic targets in COVID-19 with AKI and CKD. Common genes and pathways may play pathogenic roles in these three diseases mainly through the activation of immune inflammation. Networks of transcription factor (TF)-gene, miRNA-gene, and gene-disease interactions from the datasets were also constructed, and key gene regulators influencing the progression of these three diseases were further identified among the DEGs. Moreover, new drug targets were predicted based on these common DEGs, and molecular docking and molecular dynamics (MD) simulations were performed. Finally, a diagnostic model of COVID-19 was established based on these common DEGs. Taken together, the molecular and signaling pathways identified in this study may be related to the mechanisms by which SARS-CoV-2 infection affects renal function. These findings are significant for the effective treatment of COVID-19 in patients with kidney diseases.

Abstract
Singapore grouper iridovirus (SGIV) is a highly pathogenic double-stranded DNA virus, and the fatality rate of SGIV-infected grouper is more than 90%. Up to now, there is no effective methods to control the disease. Long non-coding RNAs (lncRNAs) might play an important role in individual growth and development, immune regulation and other life processes. In this study, lncRNAs were identified in Epinephelus coioides, an important economic aquaculture marine fish in China and Southeast Asia, and the regulatory relationships of lncRNAs and mRNA response to SGIV infection were analyzed. A total of 11,678 lncRNAs were identified and classified from the spleen and GS (grouper spleen) cells. 105 differentially expressed lncRNAs (DElncRNAs) were detected during SGIV infection. The lncRNAs and the regulated mRNAs were analyzed using co-expression network, lncRNA target gene annotation and GO enrichment. At 24 and 48 h after SGIV infection, 118 and 339 lncRNA-mRNA pairs in GS cells were detected, and 728 and 688 differentially expressed lncRNA-mRNA pairs in spleen were obtained, respectively. GO and KEGG were used to predict the DE lncRNAs' target genes, and deduce the DE lncRNAs-affected signaling pathways. In GS cells, lncRNAs might participate in cell part, binding and catalytic activity; and lncRNAs might be involved in immune system process and transcription factor activity in spleen. These data demonstrated that lncRNAs could regulate the expression of immune-related genes response to viral infection, and providing a new insight into understanding the complexity of immune regulatory networks mediated by lncRNAs during viral infection in teleost fish.

Abstract
Inflammation is the common pathological basis of autoimmune diseases, metabolic diseases, malignant tumors, and other major chronic diseases. Inflammation plays an important role in tissue homeostasis. On one hand, inflammation can sense changes in the tissue environment, induce imbalance of tissue homeostasis, and cause tissue damage. On the other hand, inflammation can also initiate tissue damage repair and maintain normal tissue function by resolving injury and restoring homeostasis. These opposing functions emphasize the significance of accurate regulation of inflammatory homeostasis to ameliorate inflammation-related diseases. Potential mechanisms involve protein phosphorylation modifications by kinases and phosphatases, which have a crucial role in inflammatory homeostasis. The mechanisms by which many kinases resolve inflammation have been well reviewed, whereas a systematic summary of the functions of protein phosphatases in regulating inflammatory homeostasis is lacking. The molecular knowledge of protein phosphatases, and especially the unique biochemical traits of each family member, will be of critical importance for developing drugs that target phosphatases. Here, we provide a comprehensive summary of the structure, the "double-edged sword" function, and the extensive signaling pathways of all protein phosphatases in inflammation-related diseases, as well as their potential inhibitors or activators that can be used in therapeutic interventions in preclinical or clinical trials. We provide an integrated perspective on the current understanding of all the protein phosphatases associated with inflammation-related diseases, with the aim of facilitating the development of drugs that target protein phosphatases for the treatment of inflammation-related diseases.

Zheng X, Li C, Gao X. Overexpression of miR‑375 reverses the effects of dexamethasone on the viability, migration, invasion and apoptosis of human airway epithelial cells by targeting DUSP6. Int J Mol Med 2022; 49:26. [PMID: 35014672 PMCID: PMC8788922 DOI: 10.3892/ijmm.2022.5081] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Accepted: 11/03/2021] [Indexed: 11/09/2022] Open
Abstract
Airway epithelial cell (AEC) dysfunction has been proven to be involved in the pathogenesis of asthma, which may be induced by the use of dexamethasone (Dex). The altered expression of microRNAs (miRNAs/miRs) has been found in asthma. However, the detailed mechanisms responsible for the effects of miR-375 on Dex-induced AEC dysfunction remain elusive. Thus, the present study aimed to elucidate these mechanisms. Following treatment with Dex for 0, 6, 12 and 24 h, AEC viability, migration, invasion and apoptosis were examined using Cell Counting Kit-8 (CCK-8), wound healing and Transwell assays, and flow cytometry, respectively. The expression levels of miR-375, dual specificity phosphatase 6 (DUSP6) and apoptosis-related proteins (Bcl-2, Bax, cleaved caspase-3) were measured using reverse transcription-quantitative polymerase chain reaction and western blot analysis. The target genes and potential binding sites of miR-375 and DUSP6 were predicted using TargetScan and confirmed using dual-luciferase reporter assay. The viability, migration, invasion and apoptosis of Dex-treated AECs were further assessed with or without miR-375 and DUSP6. In the AECs (9HTE cells), Dex treatment suppressed cell viability and miR-375 expression, whereas it promoted cell apoptosis and the expression of DUSP6, the target gene of miR-375. The overexpression of miR-375 reversed the effects of Dex treatment on miR-375 expression, cell viability, migration and invasion, and apoptosis-related protein expression; in turn, these effects were reversed by the overexpression of DUSP6, with the exception of miR-375 expression. On the whole, the present study demonstrates that the overexpression of miR-375 counteracts the effects of Dex treatment on AEC viability, migration, invasion and apoptosis by targeting DUSP6. Thus, it was suggested that the downregulated expression of miR-375 may be a therapeutic target for AEC dysfunction.

Abstract
BACKGROUND Dual-specificity phosphatases (DUSPs) belong to the family of protein tyrosine phosphatases, which can dephosphorylate both serine/threonine and tyrosine residues. During the past decades, DUSPs have been implicated in various physiological and pathological activities. Besides mitogen-activated protein kinases (MAPKs) as the main substrates, other protein and nonprotein substrates can also be dephosphorylated by DUSPs. Aberrant regulations of DUSPs have been found in various diseases such as cancer, neurological disorders, and kidney diseases, suggesting the involvement of DUSPs in the pathogenesis of diseases. SUMMARY In this review, we summarize the general characteristics of DUSPs and the research progress made in the field of kidney diseases, including diabetic nephropathy, hypertensive nephropathy, chronic kidney disease, acute kidney injury, and lupus nephritis. As the main biochemical function of DUSPs is to dephosphorylate MAPKs activity, decreased DUSPs are found in kidney disease models, whereas forced DUSPs expression reverses the disease presentation, which was proved by using transgenic or gene knockout model. KEY MESSAGES Mounting evidence demonstrates that DUSPs have essential physiological and pathological functions in kidney disease. Fully understanding the functions and mechanisms of DUSPs in kidney disease contributes to their clinical application in translation medicine.
