Zhao X, Yuan W, Yang L, Yan F, Cui D. Ginsenoside Rh2 suppresses ferroptosis in ulcerative colitis by targeting specific protein 1 by upregulating microRNA-125a-5p. Eur J Med Res 2024; 29:450. [PMID: 39223620 PMCID: PMC11370063 DOI: 10.1186/s40001-024-02025-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Accepted: 08/13/2024] [Indexed: 09/04/2024] Open
Abstract
BACKGROUND Worldwide, ulcerative colitis (UC) is becoming increasingly fast growing. Ginsenoside Rh2 has been reported to alleviate UC. However, the latent biological mechanism of Rh2 in the treatment of UC remains uncertain. In this study, the goal was to determine the therapeutic effect of Rh2 on dextran sulfate sodium (DSS)-induced UC. METHODS A DSS-induced UC mouse model was established and divided into 7 groups for Rh2 gavage and/or miR-125a-5p lentivirus injection (n = 10 per group). Colonic specimens were collected for phenotypic and pathological analysis. miR-125a-5p and specific protein 1 (SP1) expression, inflammation-related factors IL-6 and IL-10, and apoptosis were detected in mice. Human normal colon epithelial cell line NCM460 was treated with H2O2 and ferric chloride hexahydrate to construct an in vitro cell model of colitis and induce ferroptosis. Independent sample t-test was used to compare cell proliferation, cell entry, apoptosis, and oxidative stress between the two groups. One way analysis of variance combined with the least significant difference t test was used for comparison between groups. Multiple time points were compared by repeated measurement analysis of variance. RESULTS DSS-induced UC mice had significantly decreased body weight, increased disease activity index, decreased colon length, and decreased miR-125a-5p expression (all P < 0.05). In the DSS-induced mouse model, the expression of miR-125a-5p rebounded and ferroptosis was inhibited after Rh2 treatment (all P < 0.05). Inhibition of miR-125a-5p or upregulation of SP1 expression counteracted the protective effects of Rh2 on UC mice and ferroptosis cell models (all P < 0.05). CONCLUSIONS Rh2 mitigated DSS-induced colitis in mice and restrained ferroptosis by targeting miR-125a-5p. Downregulating miR-125a-5p or elevating SP1 could counteract the protective impacts of Rh2 on ferroptotic cells. The findings convey that Rh2 has a latent application value in the treatment of UC.

Abstract
MicroRNAs (miRNAs) are small, non-coding RNA molecules that play a crucial role in regulating gene expression by inhibiting the translation of their specific target messenger RNAs. To date, numerous studies have demonstrated changes in the expression of miRNAs in the kidneys throughout the progression of both acute kidney injury (AKI) and chronic kidney disease (CKD) in both human patients and experimental models. The role of specific microRNAs in the pathogenesis of kidney diseases has also been demonstrated. Further studies have elucidated the regulation of these microRNAs in diseased kidneys. Besides, certain miRNAs are detected in plasma and/or urine in kidney diseases and are potential diagnostic biomarkers. In this review, we provide an overview of recent developments in our understanding of how miRNAs contribute to kidney diseases. We also explore the potential of miRNAs as both biomarkers and therapeutic targets for these conditions, and highlight future research directions.

[PMID: 38988131 PMCID: PMC11237170 DOI: 10.1111/srt.13630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Accepted: 02/12/2024] [Indexed: 07/12/2024]
Abstract
OBJECTIVE To investigate the role of NEAT1 targeted regulation of miR-125/ADAM9 mediated NF-κB pathway in inflammatory response in rosacea. METHOD HaCaT cell rosacea phenotype was induced by LL37. The connection targeted by NEAT1 and miR-125a-5p was confirmed by Double-Luciferase report analysis. qPCR was employed to assess the levels of expression for NEAT1, miR-125a-5p, and ADAM9 genes. The levels of expression for ADAM9/TLR2/NF-κB P65 pathway proteins in each batch of cells were determined by Western blotting. The levels of expression for inflammatory factors, including TNF-α, IL-1β, IL-6, and IL-18, were measured through ELISA experimentation. RESULTS LL37 could successfully induce HaCaT cells to exhibit rosacea phenotype. The luciferase report experiment confirmed that NEAT1 could target and bind miR-125a-5p and inhibit its expression. ADAM9 exhibited increased expression in LL37-induced HaCaT cells, showing a positive association with NEAT1 expression and inverse relationship with miR-125a-5p activation. LL37 treatment promoted the expression of ADAM9/TLR2/NF-κB P65 pathway proteins. Silencing ADAM9 can inhibit the inflammatory signaling pathway and reduce the level of TNF-α, IL-1β, IL-6, and IL-18 in HaCaT cells. CONCLUSION NEAT1 can suppress the production of miR-125a-5p and activate the TLR2/NF-κB inflammatory pathway mediated by ADAM9, thereby promoting the inflammatory response in rosacea.

Abstract
Macrophages, crucial components of the human immune system, can be polarized into M1/M2 phenotypes, each with distinct functions and roles. Macrophage polarization has been reported to be significantly involved in the inflammation and fibrosis observed in kidney injury. MicroRNA (miRNA), a type of short RNA lacking protein-coding function, can inhibit specific mRNA by partially binding to its target mRNA. The intricate association between miRNAs and macrophages has been attracting increasing interest in recent years. This review discusses the role of miRNAs in regulating macrophage-mediated kidney injury. It shows how miRNAs can influence macrophage polarization, thereby altering the biological function of macrophages in the kidney. Furthermore, this review highlights the significance of miRNAs derived from exosomes and extracellular vesicles as a crucial mediator in the crosstalk between macrophages and kidney cells. The potential of miRNAs as treatment applications and biomarkers for macrophage-mediated kidney injury is also discussed.

Abstract
Intervertebral disc degeneration (IVDD) is the pathological basis of a range of degenerative spinal diseases and is the primary cause of lower back pain. Mesenchymal stem cell (MSC) transplantation inhibits IVDD progression. However, the specific mechanisms that underlie these effects remain unclear. In this study, candidate microRNAs (miRNAs) are screened using bioinformatics and high-throughput sequencing. TNF-α is used to induce nucleus pulposus cell (NPC) degeneration. MSC-derived exosomes (MSC-exosomes) are obtained using high-speed centrifugation and identified by transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA) and western blot analysis. Cell viability is determined by CCK-8 assay. Flow cytometry and TUNEL assays are used to detect cell apoptosis. The expression levels of miR-125b-5p are detected by RT-qPCR, and a dual-luciferase gene reporter assay confirms the downstream target genes of miR-125b-5p. Protein expression is determined by western blot analysis. Rat models are used to validate the function of miR-125b-5p in MSC-exosomes. The results show that miR-125b-5p is expressed at low levels in degenerated disc tissues compared with that in normal disc tissues; however, it is highly expressed in MSC-exosomes. Furthermore, MSC-exosomes are efficiently taken up by NPCs while miR-125b-5p is delivered into NPCs; thus, MSC-exosomes act as inhibitors of apoptosis in NPCs. Overexpression of miR-125b-5p downregulates TRAF6 expression and inhibits NF-κB activation. However, TRAF6 overexpression reverses these effects of miR-125b-5p. We demonstrate that MSC-exosomes attenuate IVDD in vivo by delivering miR-125b-5p. MSC-exosomes can deliver miR-125b-5p to target TRAF6, inhibit NF-κB activation, and attenuate the progression of IVDD.

Abstract
Hemophilic arthropathy (HA) due to repeated bleeding into the joint cavity is a major cause of morbidity in patients with hemophilia. The molecular mechanisms contributing to this condition are not well characterized. MicroRNAs (miRs) are known to modulate the phenotype of multiple joint diseases such as osteoarthritis (OA) and rheumatoid arthritis (RA). Since miR125a is known to modulate disease progression in OA and RA, we performed a targeted screen of miR125a-5p and its target genes in a murine model of chronic HA. A digital PCR analysis demonstrated significant downregulation of miR125a-5p (2-fold vs control joint). Further molecular evaluation revealed elevated expression of the immunological markers STAT1 (7.6-fold vs control joint) and TRAF6 (10.6 fold vs control joint), which are direct targets of miR125a-5p. We then studied the impact of targeted overexpression of miR125a-5p using an Adeno-associated virus (AAV) vector in modulating the molecular mediators of HA. AAV5-miR125a vectors were administered intra-articularly either alone or in combination with a low dose of AAV8-based human factor 8 (F8) gene in a murine model of HA. We observed significantly increased expression of miR125a-5p in AAV5-miR125a administered mice (~12 fold vs injured joint) or in combination with AAV8-F8 vectors (~44 fold vs injured joint). The activity assay revealed ~17 %-20 % FVIII levels in mice that received low dose liver-directed F8 gene therapy. Further immunohistochemical analysis, demonstrated a decrease in inflammatory markers (STAT1 and TRAF6) and cartilage-degrading matrix metalloproteinases (MMPs) 3, 9, 13 in the joints of treated animals. These data highlight the crucial role of miR125a-5p in the development of HA.

Drug metabolism and inflammation related distinct miRNA signature of colchicine resistant familial Mediterranean fever patients. Int Immunopharmacol 2023; 124:111011. [PMID: 37844462 DOI: 10.1016/j.intimp.2023.111011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2023] [Revised: 09/14/2023] [Accepted: 09/27/2023] [Indexed: 10/18/2023]
Abstract
OBJECTIVE Colchicine is the primary treatment for familial Mediterranean fever (FMF). Although colchicine is safe and effective in FMF patients, around 5-10% of patients show resistance to the drug. This study investigates the possibility of a link between colchicine resistance and the distinct miRNA profiles in colchicine resistant FMF patients. METHODS Differentially expressed miRNAs in colchicine resistant FMF patients were detected by Affymetrix 4.0 miRNA array analysis. These miRNAs were then categorized based on the role of their target genes in drug metabolism and inflammation related pathways. qRT-PCR was used to validate candidate miRNAs selected by Enrichr, a gene enrichment analysis system based on the relevance of possible target genes in drug metabolism pathways. Expression levels of these miRNAs' potential target genes were investigated by qRT-PCR. Then, a colchicine resistant hepatoblastoma cell line (HEPG2) was established, and the differentially expressed miRNAs and genes identified in patients were also analyzed in this colchicine-resistant cell line. RESULTS 25 differentially expressed miRNAs were detected in colchicine resistant FMF patients. miR-183-5p, miR-15b-5p, miR-505-5p, and miR-125a-5p were identified to be associated with drug resistance and inflammatory pathways and thus chosen for further validation. miR-183-5p, miR-15b-5p, miR-505-5p miRNAs showed significantly differential expression in qRT-PCR. NFKB1, NR3C1, PPARα - drug absorption, distribution, metabolism, and excretion (ADME) genes were predicted to be targeted by these miRNAs. Among these targets, NFKB1 and NR3C1 were differentially over expressed in colchicine resistant FMF patients. These findings were validated in the colchicine resistant hepatoblastoma cell line (HEPG2). CONCLUSION This is the first study evaluating the role of miRNAs in colchicine resistant patients with FMF. Their differential expression may result in resistance to standard colchicine treatment by affecting the expression of genes that take place in drug absorption, distribution, metabolism, and excretion (ADME) or nuclear receptors that regulate ADME genes, thus potentially playing a role in both drug metabolism and inflammation.

Abstract
OBJECTIVE Hypertriglyceridemia (HTG) is one of the common causes of acute pancreatitis (AP). Hyperlipidemic acute pancreatitis (HTG-AP) is associated with higher mortality owing to its tendency for greater severity and rapid progression. The purpose of this study was to explore the mechanism of involvement of tumor necrosis factor receptor-related factor 6 (TRAF6) in pyroptosis during HTG-AP. METHODS The HTG environment was simulated with palmitic acid treatment in vitro and a high-fat diet in vivo. Cerulein was used to establish the HTG-AP model, followed by genetic and pharmacological inhibition of TRAF6. Pyroptosis activation, inflammatory reaction, and the interaction between TRAF6 and pyroptosis in HTG-AP were assessed. RESULTS HTG was found to aggravate the development of pancreatitis, accompanied by increased pyroptosis and enhanced inflammatory response in HTG-AP models. Mechanistically, TRAF6 downregulation decreased the activation of pyroptosis in cerulein-induced HTG-AP. CONCLUSION Collectively, inhibition of TRAF6 improved HTG-AP and the associated inflammation by alleviating pyroptosis.

Abstract
Sepsis is a potentially fatal complication of burns and trauma that can cause acute kidney injury (AKI) with substantial morbidity and mortality, but this disease is poorly understood. Despite medical advances, effective therapeutic regimens for septic AKI remain uncommon. MicroRNAs (miRNAs) are endogenous non-coding RNAs that influence the translation of target messenger RNAs in a variety of biological processes. Emerging evidence has shown that miRNAs are intimately associated with septic AKI. The goal of this review was to summarize recent advances in the profound understanding of the functional role of miRNAs in septic AKI, as well as to provide new insights into miRNAs as feasible biomarkers and therapeutic targets for septic AKI.

Abstract
Deep vein thrombosis (DVT) is a common and fatal disease with a pathology involving endothelial dysfunction. The present research aimed to address the potential clinical significance of miR-125a-5p in DVT and its effect on the dysfunction of Human umbilical vein endothelial cells (HUVECs). Serum miR-125a-5p levels were measured using RT-qPCR in 88 patients with DVT and 76 healthy controls. ROC was plotted to evaluate the diagnostic potential of miR-125a-5p. Spearman's correlation coefficient was performed to calculate the correlation between miR-125a-5p and clinical indicators. CCK-8, Transwell, and ELISA were employed to verify the effects of cell proliferation, migration, and inflammatory and adhesion molecules. Dual-luciferase reporter assay to analyze potential target for miR-125a-5p. Serum miR-125a-5p was reduced in patients with DVT compared with healthy controls (P < 0.001). ROC showed that miR-125a-5p significantly identified patients with DVT from the healthy controls (AUC = 0.834). Furthermore, serum miR-125a-5p was negatively correlated with inflammatory factors and coagulation factors. In in vitro studies, proliferation and migration of HUVECs were inhibited by suppressed miR-125a-5p, whereas inflammation and adhesion factors were considerably promoted (P < 0.05). Moreover, miR-125-5p directly targeted the 3'UTR of angiopoietin 2 (ANGPT2) and was negatively regulated. Finally, serum ANGPT2 was elevated in patients with DVT and was negatively correlated with serum miR-125a-5p. The current research demonstrated that decreased miR-125a-5p was a novel potential diagnostic biomarker for DVT and that it may be involved in DVT progression by targeting ANGPT2 to regulate endothelial dysfunction.

Abstract
Despite more than a decade of active study, tuberculosis (TB) remains a serious health concern across the world, and it is still the biggest cause of mortality in the human population. Pathogenic bacteria recognize host-induced responses and adapt to those hostile circumstances. This high level of adaptability necessitates a strong regulation of bacterial metabolic characteristics. Furthermore, the immune reponse of the host virulence factors such as host invasion, colonization, and survival must be properly coordinated by the pathogen. This can only be accomplished by close synchronization of gene expression. Understanding the molecular characteristics of mycobacterial pathogenesis in order to discover therapies that prevent or resolve illness relies on the bacterial capacity to adjust its metabolism and replication in response to various environmental cues as necessary. An extensive literature details the transcriptional alterations of host in response to in vitro environmental stressors, macrophage infection, and human illness. Various studies have recently revealed the finding of several microRNAs (miRNAs) that are believed to play an important role in the regulatory networks responsible for adaptability and virulence in Mycobacterium tuberculosis. We highlighted the growing data on the existence and quantity of several forms of miRNAs in the pathogenesis of M. tuberculosis, considered their possible relevance to disease etiology, and discussed how the miRNA-based signaling pathways regulate bacterial virulence factors.

Abstract
Acute renal injury (AKI) is a complex clinical syndrome, involving a series of pathophysiological processes, in which inflammation plays a key role. Identification and verification of gene signatures associated with inflammatory onset and progression are imperative for understanding the molecular mechanisms involved in AKI pathogenesis. Non-coding RNAs (ncRNAs), involved in epigenetic modifications of inflammatory responses, are associated with the aberrant expression of inflammation-related genes in AKI. However, its regulatory role in gene expression involves precise transcriptional regulation mechanisms which have not been fully elucidated in the complex and volatile inflammatory response of AKI. In this study, we systematically review current research on the intrinsic molecular mechanisms of ncRNAs that regulate the inflammatory response in AKI. We aim to provide potential research directions and strategies for developing ncRNA-targeted gene therapies as an intervention for the inflammatory damage in AKI.

Abstract
Chronic kidney disease (CKD) and acute kidney injury (AKI) are public health problems, and their prevalence rates have increased with the aging of the population. They are associated with the presence of comorbidities, in particular diabetes mellitus and hypertension, resulting in a high financial burden for the health system. Studies have indicated Klotho as a promising therapeutic approach for these conditions. Klotho reduces inflammation, oxidative stress and fibrosis and counter-regulates the renin-angiotensin-aldosterone system. In CKD and AKI, Klotho expression is downregulated from early stages and correlates with disease progression. Therefore, the restoration of its levels, through exogenous or endogenous pathways, has renoprotective effects. An important strategy for administering Klotho is through mesenchymal stem cells (MSCs). In summary, this review comprises in vitro and in vivo studies on the therapeutic potential of Klotho for the treatment of CKD and AKI through the administration of MSCs.

Abstract
OBJECTIVE Sepsis-associated encephalopathy (SAE) is a severe and common complication of sepsis and can induce cognitive dysfunction and apoptosis of neurons and neuroinflammation. Emodin has been confirmed to have anti-inflammatory effects. Thus, we sought to investigate the role of Emodin in SAE. METHODS The cecal ligation and puncture (CLP) method was used for the establishment of SAE in mice model. For treatment of Emodin, intraperitoneal injection of 20 mg/kg Emodin was performed before the surgery. The Morris water maze and open field tests were carried for measurement of cognitive dysfunction. Hematoxylin and eosin staining was for histological analysis of hippocampus. Cell apoptosis of hippocampus neurons was measured by TUNEL staining. Pro-inflammatory and anti-inflammatory cytokines in hippocampus tissue homogenate were evaluated by ELISA. BDNF/TrkB signaling-related proteins (TrkB, p-TrkB, and BDNF), autophagy-related proteins (LC3 II/I and Beclin-1), and apoptosis-related proteins (Bax, Bcl-2, and cleaved caspase-3) were detected by Western blotting. RESULTS Emodin significantly inhibited apoptosis and induced autophagy in hippocampal neurons of CLP-treated mice. In addition, Emodin significantly ameliorated CLP-induced cognitive dysfunction and pathological injury in mice. Meanwhile, Emodin notably inhibited CLP-induced inflammatory responses in mice via upregulation of BDNF/TrkB signaling, while the effect of Emodin was partially reversed in the presence of K252a (BDNF/TrkB signaling inhibitor). CONCLUSION Emodin significantly inhibited the progression of SAE via mediation of BDNF/TrkB signaling. Thus, Emodin might serve as a new agent for SAE treatment.
