J Reprod Immunol 2024; 162:104205. [PMID: 38262261 DOI: 10.1016/j.jri.2024.104205] [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: 08/16/2023] [Revised: 12/12/2023] [Accepted: 01/14/2024] [Indexed: 01/25/2024]
Abstract
BACKGROUND There is increasing evidence that circular RNAs (circRNAs) are involved in the processes of preeclampsia (PE). Circ_0030042 was found to be abnormally expressed in PE patients. However, the role and molecular mechanism of circ_0030042 in PE progression remains unclear. METHODS Quantitative real-time PCR was used for determining the expression of circ_0030042, microRNA (miR)- 942-5p and lipopolysaccharide induced TNF-α factor (LITAF). Trophoblast cell functions were determined using cell counting kit 8 assay, EdU assay, flow cytometry and transwell assay. The protein levels of epithelial-mesenchymal transition (EMT)-related markers and LITAF were examined using western blot analysis. Dual-luciferase reporter assay and RNA pull-down assay were used to verify RNA interaction. RESULTS Circ_0030042 had an elevated expression in PE patients, and its overexpression inhibited trophoblast cell growth, invasion, and EMT process. Circ_0030042 served as miR-942-5p sponge, and miR-942-5p inhibitor also reversed the regulation of circ_0030042 on trophoblast cell growth, invasion and EMT process. LITAF was targeted by miR-942-5p, and its knockdown abolished the inhibition effect of miR-942-5p on trophoblast cell growth, invasion, and EMT process. Also, circ_0030042 regulated LITAF expression via sponging miR-942-5p. CONCLUSION Circ_0030042 regulated trophoblast cell growth, invasion, and EMT process via the miR-942-5p/LITAF axis, providing a novel insight for PE treatment.

Abstract
Purpose Sepsis-induced acute lung injury is related to high mortality. MiR-2113 possesses important functions in human diseases. This research aimed to clarify the role and mechanism of miR-2113 in sepsis-induced acute lung injury. Methods The expression of miR-2113 in lipopolysaccharide (LPS)-induced MLE-12 cells, serum of sepsis patients, and cecal ligation and puncture mouse models was examined using quantitative real-time PCR. The functions of miR-2113 in LPS-treated MLE-12 cells were estimated by Cell Counting Kit-8 assay, flow cytometry, enzyme-linked immunosorbent assay, Western blot, and immunofluorescence. The influences of miR-2113 in cecal ligation and puncture-induced acute lung injury in mice were assessed by hematoxylin-eosin staining, terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling assay, acute pulmonary dysfunction analysis, lactate dehydrogenase levels and total protein concentrations in bronchoalveolar lavage fluid, and Masson staining. Also, the mechanism of miR-2113 was examined using a dual-luciferase reporter assay. Results MiR-2113 expression was decreased in LPS-induced MLE-12 cells, serum of sepsis patients, and cecal ligation and puncture mouse models. miR-2113 overexpression restored LPS-reduced MLE-12 cell proliferation, but alleviated LPS-induced apoptosis and markers of inflammation and fibrosis in MLE-12 cells. Moreover, we found that miR-2113 mimic reduced LPS-induced MLE-12 cell injury by negatively regulating high-mobility group box 1. In vivo data further confirmed that miR-2113 overexpression alleviated acute pulmonary dysfunction, inflammation and fibrosis in cecal ligation and puncture-induced sepsis mice. Conclusion MiR-2113 relieved sepsis-induced acute pulmonary dysfunction, inflammation and fibrosis through decreasing high-mobility group box 1.

Mao X, Wu Y, Xu W. miR-126-5p expression in the plasma of patients with sepsis-induced acute lung injury and its correlation with inflammation and immune function. THE CLINICAL RESPIRATORY JOURNAL 2023. [PMID: 37248197 PMCID: PMC10363794 DOI: 10.1111/crj.13646] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 05/04/2023] [Accepted: 05/12/2023] [Indexed: 05/31/2023]
Abstract
OBJECTIVE This work was implemented to elucidate the miR-126-5p expression in the plasma of patients with sepsis-induced acute lung injury (ALI) and its correlation with inflammation and immune function. METHODS The peripheral blood of patients with sepsis-induced ALI was obtained, and the levels of inflammatory factors (interleukin-6 [IL-6], C-reactive protein [CRP], and procalcitonin [PCT]) were determined. Meanwhile, T lymphocyte subsets (CD3+, CD4+, and CD8+), and immunoglobulins (IgA, IgM, and IgG) were tested. miR-126-5p and TRAF6 mRNA expression in plasma was assessed. Receiver operating characteristic (ROC) curve was performed to assess the diagnostic accuracy of miR-126-5p in sepsis without ALI and sepsis with ALI. Correlation between miR-126-5p expression and clinical indicators was analyzed. The targets of miR-126-5p were predicted using the bioinformatics method, and the direct targets were verified through investigations. RESULTS miR-126-5p expression in plasma of patients with sepsis-induced ALI was reduced than that of patients with sepsis without ALI. miR-126-5p expression was negatively correlated with IL-6, CRP, and PCT but positively correlated with IgA, IgM, and IgG as well as CD3+, CD4+, and CD8+ in patients with sepsis-induced ALI. ROC curve suggested that miR-126-5p (AUC: 0.777; 95%CI: 0.689-0.866) could distinguish patients with sepsis with ALI from patients with sepsis without ALI. TRAF6 expression in patients with sepsis-induced ALI was higher than that in patients with sepsis without ALI. TRAF6 was a target gene of miR-126-5p, CONCLUSION: This research highlights that miR-126-5p is reduced in the plasma of patients with sepsis-induced ALI, and miR-126-5p relates to systemic inflammation and immune function indicators.

Abstract
BACKGROUND Coronary artery disease (CAD) is a common coronary artery disease. The functional mechanism of circular RNA (circRNA) HECT, C2 and WW domain containing E3 ubiquitin protein ligase 2 (circ_HECW2, hsa_circ_0057583) in ox-LDL-treated human cardiac microvascular endothelial cells (hCMECs) is still unclear. METHODS Expression levels of circ_HECW2, microRNA (miR)-942-5p, and toll-like receptor 4 (TLR4) were analyzed by quantitative real-time PCR (qRT-PCR) and western blot assays. Cell proliferation and apoptosis were analyzed by 5-ethynyl-2'-deoxyuridine (EdU) assay, cell counting kit-8 (CCK8) assay, and flow cytometry, respectively. Tube formation assay was performed to analyze the angiogenesis of cells. Luciferase reporter and RNA pull-down assays were performed to analyze the target relationship among circ_HECW2, miR-942-5p and TLR4. RESULTS Circ_HECW2 and TLR4 expression levels were up-regulated and miR-942-5p expression was decreased in the serum of CAD patients and oxidized low-density lipoprotein (ox-LDL)-induced hCMECs. Knockdown of circ_HECW2 enhanced cell proliferation and inhibited cell apoptosis in ox-LDL-treated hCMECs. MiR-942-5p was the target of circ_HECW2 and directly targeted TLR4. Moreover, the effect of circ_HECW2 knockdown could be weakened by anti-miR-942-5p, and TLR4 could restore the function of miR-942-5p on cell damage of ox-LDL-induced hCMECs. CONCLUSION Circ_HECW2 could regulate ox-LDL-induced cardiovascular endothelial cell dysfunction through targeting miR-942-5p/TLR4 axis.

Expression of MicroRNAs in Sepsis-Related Organ Dysfunction: A Systematic Review. Int J Mol Sci 2022; 23:ijms23169354.

Abstract
Sepsis is a critical condition characterized by increased levels of pro-inflammatory cytokines and proliferating cells such as neutrophils and macrophages in response to microbial pathogens. Such processes lead to an abnormal inflammatory response and multi-organ failure. MicroRNAs (miRNA) are single-stranded non-coding RNAs with the function of gene regulation. This means that miRNAs are involved in multiple intracellular pathways and thus contribute to or inhibit inflammation. As a result, their variable expression in different tissues and organs may play a key role in regulating the pathophysiological events of sepsis. Thanks to this property, miRNAs may serve as potential diagnostic and prognostic biomarkers in such life-threatening events. In this narrative review, we collect the results of recent studies on the expression of miRNAs in heart, blood, lung, liver, brain, and kidney during sepsis and the molecular processes in which they are involved. In reviewing the literature, we find at least 122 miRNAs and signaling pathways involved in sepsis-related organ dysfunction. This may help clinicians to detect, prevent, and treat sepsis-related organ failures early, although further studies are needed to deepen the knowledge of their potential contribution.

Abstract
The aim of the present study was to investigate the effects of microRNA (miR)-374a-5p on sepsis-induced acute lung injury (ALI) and the associated mechanism. Lipopolysaccharide (LPS)-induced human pulmonary microvascular endothelial cells (HPMVECs) were used to construct the cellular model of sepsis. A luciferase reporter assay was performed to confirm the association between miR-374a-5p and zinc finger E-box binding homeobox 1 (ZEB1). Reverse transcription-quantitative polymerase chain reaction and western blot analysis were performed to assess the relative expression of miR-374a-5p, ZEB1 and apoptosis-related proteins. Cell viability and apoptosis were determined by Cell Counting Kit-8 assay and flow cytometry, respectively. Enzyme-linked immunosorbent assays were used to evaluate inflammatory cytokines. The results revealed that miR-374a-5p was downregulated in sepsis patients and LPS-treated HPMVECs. Upregulation of miR-374a-5p alleviated LPS-triggered cell injury in HPMVECs, as evidenced by restoration of cell viability, and inhibition of apoptosis and the production of proinflammatory cytokines. In addition, ZEB1 was revealed to be a downstream target of miR-374a-5p, and overexpression of ZEB1 could reverse the anti-apoptotic and anti-inflammatory effects of miR-374a-5p on an LPS-induced sepsis cell model. Moreover, miR-374a-5p-induced protective effects involved the p38 MAPK signaling pathway. Collectively, miR-374a-5p exerted a protective role in sepsis-induced ALI by regulating the ZEB1-mediated p38 MAPK signaling pathway, providing a potential target for the diagnosis and treatment of sepsis.

Abstract
MicroRNAs (miRNAs) have been demonstrated to play pivotal roles in the pathogenesis of sepsis-induced acute lung injury (ALI). In this work, we aimed to clarify the potential role and the underlying mechanism of miR-942-5p in a lipopolysaccharide (LPS)-induced A549 cell injury model. The cell injury was evaluated by CCK-8 assay, flow cytometry and enzyme-linked immunosorbent assay (ELISA). The expression levels of miR-942-5p and tripartite motif-containing protein 37 (TRIM37) were measured by real-time PCR and Western blot, and their association was then validated by bioinformatics, luciferase reporter assay and RNA pull-down assay. We found that the expression of miR-942-5p was decreased in LPS-treated A549 cells. Furthermore, LPS treatment suppressed A549 cell viability, promoted apoptosis and increased the levels of inflammatory cytokines. Conversely, overexpression of miR-942-5p increased cell viability, reduced apoptosis and alleviated inflammatory cytokine secretion in the presence of LPS. Moreover, miR-942-5p directly targeted TRIM37 by binding to the 3'-UTR of TRIM37 mRNA. Upregulation of TRIM37 effectively reversed the anti-apoptotic and anti-inflammatory effects of miR-942-5p in LPS-induced A549 cells. Our findings suggested that miR-942-5p protected against LPS-induced cell injury through inhibiting apoptosis and inflammation in A549 cells by negatively regulating TRIM37.
