Abstract
The mutual regulation between hydrogen sulfide (H2S) and microRNA (miRNA) is involved in the development of many diseases, including cancer, cardiovascular disease, inflammatory disease, and high-risk pregnancy. Abnormal expressions of endogenous H2S-producing enzyme and miRNA in tissues and cells often indicate the occurrence of diseases, so the maintenance of their normal levels in the body can mitigate damages caused by various factors. Many studies have found that H2S can promote the migration, invasion, and proliferation of cancer cells by regulating the expression of miRNA, while many H2S donors can inhibit cancer progression by interfering with the proliferation, apoptosis, cell cycle, metastasis, and angiogenesis of cancer cells. Furthermore, the mutual regulation between H2S and miRNA can also prevent cell injury in cardiovascular disease and inflammatory disease through anti-inflammation, anti-oxidation, anti-apoptosis, and pro-autophagy. In addition, H2S can promote angiogenesis and relieve vasoconstriction by regulating the expression of miRNA, thereby improving fetal growth in high-risk pregnancy. In this review, we discuss the mechanism of mutual regulation between H2S and miRNA in various diseases, which may provide reliable therapeutic targets for these diseases.

Zhao Y, Li T, Jiang Z, Gai C, Yu S, Xin D, Li T, Liu D, Wang Z. The miR-9-5p/CXCL11 pathway is a key target of hydrogen sulfide-mediated inhibition of neuroinflammation in hypoxic ischemic brain injury. Neural Regen Res 2024; 19:1084-1094. [PMID: 37862212 PMCID: PMC10749591 DOI: 10.4103/1673-5374.382860] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 11/05/2022] [Accepted: 07/11/2023] [Indexed: 10/22/2023] Open
Abstract
We previously showed that hydrogen sulfide (H2S) has a neuroprotective effect in the context of hypoxic ischemic brain injury in neonatal mice. However, the precise mechanism underlying the role of H2S in this situation remains unclear. In this study, we used a neonatal mouse model of hypoxic ischemic brain injury and a lipopolysaccharide-stimulated BV2 cell model and found that treatment with L-cysteine, a H2S precursor, attenuated the cerebral infarction and cerebral atrophy induced by hypoxia and ischemia and increased the expression of miR-9-5p and cystathionine β synthase (a major H2S synthetase in the brain) in the prefrontal cortex. We also found that an miR-9-5p inhibitor blocked the expression of cystathionine β synthase in the prefrontal cortex in mice with brain injury caused by hypoxia and ischemia. Furthermore, miR-9-5p overexpression increased cystathionine-β-synthase and H2S expression in the injured prefrontal cortex of mice with hypoxic ischemic brain injury. L-cysteine decreased the expression of CXCL11, an miR-9-5p target gene, in the prefrontal cortex of the mouse model and in lipopolysaccharide-stimulated BV-2 cells and increased the levels of proinflammatory cytokines BNIP3, FSTL1, SOCS2 and SOCS5, while treatment with an miR-9-5p inhibitor reversed these changes. These findings suggest that H2S can reduce neuroinflammation in a neonatal mouse model of hypoxic ischemic brain injury through regulating the miR-9-5p/CXCL11 axis and restoring β-synthase expression, thereby playing a role in reducing neuroinflammation in hypoxic ischemic brain injury.

Role of Hydrogen Sulfide in Oncological and Non-Oncological Disorders and Its Regulation by Non-Coding RNAs: A Comprehensive Review. Noncoding RNA 2024; 10:7. [PMID: 38250807 PMCID: PMC10801522 DOI: 10.3390/ncrna10010007] [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: 12/02/2023] [Revised: 01/07/2024] [Accepted: 01/08/2024] [Indexed: 01/23/2024] Open
Abstract
Recently, myriad studies have defined the versatile abilities of gasotransmitters and their synthesizing enzymes to play a "Maestro" role in orchestrating several oncological and non-oncological circuits and, thus, nominated them as possible therapeutic targets. Although a significant amount of work has been conducted on the role of nitric oxide (NO) and carbon monoxide (CO) and their inter-relationship in the field of oncology, research about hydrogen sulfide (H2S) remains in its infancy. Recently, non-coding RNAs (ncRNAs) have been reported to play a dominating role in the regulation of the endogenous machinery system of H2S in several pathological contexts. A growing list of microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) are leading the way as upstream regulators for H2S biosynthesis in different mammalian cells during the development and progression of human diseases; therefore, their targeting can be of great therapeutic benefit. In the current review, the authors shed the light onto the biosynthetic pathways of H2S and their regulation by miRNAs and lncRNAs in various oncological and non-oncological disorders.

Abstract
Several studies highlighted a significant role of specific miRNA as diagnostic and prognostic biomarkers for acute ischemic stroke. The aim of this work was to study micro-RNA 125b-5p level in patients with acute ischemic stroke in relation to stroke etiology, risk factors, severity and outcome. This case-control study was conducted on 40 patients with acute ischemic stroke eligible for receiving rt-PA and 40 age and sex matched healthy controls, Patients were submitted to neurological and radiological assessment. Functional outcome after 3 months was assessed using the modified Rankin Scale (mRS). Plasma micro-RNA 125b-5p levels were measured for both patients and control groups by quantitative real time PCR. MiRNA-125b-5p was extracted from the plasma samples then Real-time quantitative reversed transcription PCR (RT-qPCR) analysis was done. To analyze miRNA-125b-5p expression in plasma, the ∆Cq value of miRNA-125b-5p was calculated by subtracting Cq of miRNA-125b-5p from the average Cq of MiRNA RNU6B. Stroke patients had significantly higher circulating micro-RNA 125b-5p levels in comparison to healthy controls (P value = 0.01). The circulating levels of micro-RNA 125b-5p were positively correlated with stroke severity assessed by National Institutes of Health Stroke Scale (NIHSS) and infarction size. Stroke patients with poor outcome had significantly higher circulating levels of micro-RNA 125b-5p in comparison to those with good outcome (P value ≤ 0.001). The circulating levels of micro-RNA 125b-5p were significantly higher in patients who developed complications after receiving rt-PA (P value ≤ 0.001). Logistic regression model revealed that each unit increase in micro-RNA125b-5p decreased the odds of good outcome by 0.095 (95% CI 0.016-0.58, P value = 0.011). Plasma micro-RNA 125b-5p is significantly elevated is ischemic stroke patients. It is positively correlated with stroke severity and strongly associated with poor outcome and complications after thrombolytic therapy.

Abstract
Neurodegenerative diseases are critical in the healthcare system as patients suffer from progressive diseases despite currently available drug management. Indeed, the growing ageing population will burden the country's healthcare system and the caretakers. Thus, there is a need for new management that could stop or reverse the progression of neurodegenerative diseases. Stem cells possess a remarkable regenerative potential that has long been investigated to resolve these issues. Some breakthroughs have been achieved thus far to replace the damaged brain cells; however, the procedure's invasiveness has prompted scientists to investigate using stem-cell small extracellular vesicles (sEVs) as a non-invasive cell-free therapy to address the limitations of cell therapy. With the advancement of technology to understand the molecular changes of neurodegenerative diseases, efforts have been made to enrich stem cells' sEVs with miRNAs to increase the therapeutic efficacy of the sEVs. In this article, the pathophysiology of various neurodegenerative diseases is highlighted. The role of miRNAs from sEVs as biomarkers and treatments is also discussed. Lastly, the applications and delivery of stem cells and their miRNA-enriched sEVs for treating neurodegenerative diseases are emphasised and reviewed.

Abstract
Background: The incidence of respiratory diseases and the respiratory disease mortality rate have increased in recent years. Recent studies have shown that long non-coding RNA (lncRNA) MALAT1 is involved in various respiratory diseases. In vascular endothelial and cancer cells, MALAT1 expression triggers various changes such as proinflammatory cytokine expression, cancer cell proliferation and metastasis, and increased endothelial cell permeability. Methods: In this review, we performed a relative concentration index (RCI) analysis of the lncRNA database to assess differences in MALAT1 expression in different cell lines and at different locations in the same cell, and summarize the molecular mechanisms of MALAT1 in the pathophysiology of respiratory diseases and its potential therapeutic application in these conditions. Results: MALAT1 plays an important regulatory role in lncRNA with a wide range of effects in respiratory diseases. The available evidence shows that MALAT1 plays an important role in the regulation of multiple respiratory diseases. Conclusion: MALAT1 is an important regulatory biomarker for respiratory disease. Targeting the regulation MALAT1 could have important applications for the future treatment of respiratory diseases.

Abstract
Pediatric primary brain tumors represent a real challenge in the oncology arena. Besides the psychosocial burden, brain tumors are considered one of the most difficult-to-treat malignancies due to their sophisticated cellular and molecular pathophysiology. Notwithstanding the advances in research and the substantial efforts to develop a suitable therapy, a full understanding of the molecular pathways involved in primary brain tumors is still demanded. On the other hand, the physiological nature of the blood-brain barrier (BBB) limits the efficiency of many available treatments, including molecular therapeutic approaches. Hydrogen Sulfide (H2S), as a member of the gasotransmitters family, and its synthesizing machinery have represented promising molecular targets for plentiful cancer types. However, its role in primary brain tumors, generally, and pediatric types, particularly, is barely investigated. In this review, the authors shed the light on the novel role of hydrogen sulfide (H2S) as a prominent player in pediatric brain tumor pathophysiology and its potential as a therapeutic avenue for brain tumors. In addition, the review also focuses on the challenges and opportunities of several molecular targeting approaches and proposes promising brain-delivery strategies for the sake of achieving better therapeutic results for brain tumor patients.

Abstract
Ischemic stroke (IS) is a global health challenge leading to life-long disabilities or the deaths of patients. IS is a complex disease where genetic and environmental factors are both concerned with the pathophysiology of the condition. Here, we aimed to investigate various microRNA (miRNA) expressions and their targets in IS. A rapid and accurate diagnosis of acute IS is important to perform appropriate treatment. Therefore, there is a need for a more rapid and simple tool to carry out an acute diagnosis of IS. miRNAs are small RNA molecules serving as precious biomarkers due to their easy detection and stability in blood samples. The present systematic review aimed to summarize previous studies investigating several miRNA expressions and their targets in IS.

Abstract
Hydrogen Sulfide (H2S) mediates biological effects in a variety of ways. Due to its strong reducing potential, H2S has been recognized to have an important role in oxidative stress induced hypoxia. It has been reported that H2S production and miRNA can mutually regulate each other. H2S is produced by the catalytic activity of cystathionine-β-synthase (CBS), which is under the regulation of miRNAs. In this study, we used target gene prediction software, and identified miR-203 as a potential regulator of CBS. We verified this finding using an oxygen and glucose deprivation (OGD) hypoxia cell model in SH-SY5Y cells and pMIR-REPORT™ luciferase miRNA expression reporter vector. Furthermore, transfecting SH-SY5Y cells with miRNA agomir (agonist) and antagomir (antagonist) by lipofectamin RNAiMAX, we further validated miR-203 as a direct regulator of CBS. We also found that miR-203 protects from cell injury by regulating lipid peroxidation, cell apoptosis, and mitochondrial membrane potential. These findings suggest that while over-expression of miR-203 can aggravate OGD induced cell injury, inhibition of miR-203 can protect against OGD induced cell injury. Based on our data and that of others, we propose that miR-203 may regulate oxidative stress induced cell injury by regulating CBS expression and adjusting the levels of H2S production.

Abstract
Exosomes play a role as mediators of cell-to-cell communication, thus exhibiting pleiotropic activities to homeostasis regulation. Exosomal non-coding RNAs (ncRNAs), mainly microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), are closely related to a variety of biological and functional aspects of human health. When the exosomal ncRNAs undergo tissue-specific changes due to diverse internal or external disorders, they can cause tissue dysfunction, aging, and diseases. In this review, we comprehensively discuss the underlying regulatory mechanisms of exosomes in human diseases. In addition, we explore the current knowledge on the roles of exosomal miRNAs, lncRNAs, and circRNAs in human health and diseases, including cancers, metabolic diseases, neurodegenerative diseases, cardiovascular diseases, autoimmune diseases, and infectious diseases, to determine their potential implication in biomarker identification and therapeutic exploration.

Abstract
The ability to detect oxygen availability is a ubiquitous attribute of aerobic organisms. However, the mechanism(s) that transduce oxygen concentration or availability into appropriate physiological responses is less clear and often controversial. This review will make the case for oxygen-dependent metabolism of hydrogen sulfide (H2S) and polysulfides, collectively referred to as reactive sulfur species (RSS) as a physiologically relevant O2 sensing mechanism. This hypothesis is based on observations that H2S and RSS metabolism is inversely correlated with O2 tension, exogenous H2S elicits physiological responses identical to those produced by hypoxia, factors that affect H2S production or catabolism also affect tissue responses to hypoxia, and that RSS efficiently regulate downstream effectors of the hypoxic response in a manner consistent with a decrease in O2. H2S-mediated O2 sensing is then compared to the more generally accepted reactive oxygen species (ROS) mediated O2 sensing mechanism and a number of reasons are offered to resolve some of the confusion between the two.

[PMID: 34273708 DOI: 10.1016/j.jstrokecerebrovasdis.2021.105987] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 05/30/2021] [Accepted: 06/25/2021] [Indexed: 11/20/2022] Open
Abstract
OBJECTIVES The 10-O-(N N-dimethylaminoethyl)-ginkgolide B methane-sulfonate (XQ-1H) is an effective novel drug for the treatment of ischemic cerebrovascular disease derived from Ginkgolide B, a traditional Chinese medicine, has been widely used in the treatment of cardiovascular and cerebrovascular diseases. However, whether XQ-1H exerts neuroprotective effect via regulating neuronal apoptosis and the underlying mechanism remain to be elucidated. MATERIALS AND METHODS This study was aimed to investigate the neuroprotective effect of XQ-1H in rats subjected to middle cerebral artery occlusion/reperfusion (MCAO/R) and the oxygen glucose deprivation/reoxygenation (OGD/R) induced neuronal apoptosis on pheochromocytoma (PC-12) cells. RESULTS The results showed that administration of XQ-1H at different dosage (7.8, 15.6, 31.2 mg/kg) reduced the brain infarct and edema, attenuated the neuro-behavioral dysfunction, and improved cell morphology in brain tissue after MCAO/R in rats. Moreover, incubation with XQ-1H (1 µM, 3 µM, 10 µM, 50 µM, 100 µM) could increase the cell viability, and showed no toxic effect to PC-12 cells. XQ-1H at following 1 µM, 10 µM, 100 µM decreased the lactate dehydrogenase (LDH) activity and suppressed the cell apoptosis in PC-12 cells exposed to OGD/R. In addition, XQ-1H treatment could significantly inhibit caspase-3 activation both in vivo and in vitro, reciprocally modulate the expression of apoptosis related proteins, bcl-2, and bax via activating PI3K/Akt signaling pathway. For mechanism verification, LY294002, the inhibitor of PI3K/Akt pathway was introduced the expressions of bcl-2 and phosphorylated Akt were down-regulated, the expression of bax was up-regulated, indicating that XQ-1H could alleviate the cell apoptosis through activating the PI3K/Akt pathway. CONCLUSIONS Our findings demonstrated that XQ-1H treatment could provide a neuroprotective effect against ischemic stroke induced by cerebral ischemia/reperfusion injury in vivo and in vitro through regulating neuronal survival and inhibiting apoptosis. The findings of the study confirmed that XQ-1H could be develop as a potential drug for treatment of cerebral ischemic stroke.

Abstract
Hydrogen sulfide (H2S) as the third gasotransmitter molecule serves various biological regulatory roles in health and disease. Acrylonitrile (AN) is a common occupational toxicant and environmental pollutant, causing brain and liver damage in mammals. The biotransformation of AN is dependent-upon reduced glutathione (GSH), cysteine and other sulfur-containing compounds. However, the effects of AN on the endogenous H2S biosynthesis pathway have yet to be determined. Herein, we demonstrated that a single exposure to AN (at 25, 50, or 75 mg/kg for 1, 6 or 24 h) decreased the endogenous H2S content and H2S-producing capacity in a dose-dependent manner, both in the cerebral cortex and liver of rats in vivo. In addition, the inhibitory effects of AN (1, 2.5, 5, 10 mM for 12 h) on the H2S content and/or the expression of H2S-producing enzymes were also found both in primary rat astrocytes and rat liver cell line (BRL cells). Impairment in the H2S biosynthesis pathway was also assessed in primary rat astrocytes treated with AN. It was found that inhibition of the cystathionine-β-synthase (CBS)/3-mercaptopyruvate sulfurtransferase (3-MPST)-H2S pathway with the CBS inhibitor or 3-MPST-targeted siRNA significantly increased the AN-induced (5 mM for 12 h) cytotoxicity in astrocytes. In turn, CBS activation or 3-MPST overexpression as well as exogenous NaHS supplementation significantly attenuated AN-induced cytotoxicity. Taken together, endogenous H2S biosynthesis pathway was disrupted in rats acutely exposed to AN, which contributes to acute AN neurotoxicity in primary rat astrocytes.

Abstract
The aim of the present study was to determine the function of microRNA (miR)-125b-5p in lumbar disc degeneration (LDD). Nucleus pulposus (NP) cells were stimulated with 10 ng/ml IL-1β for 24 h to establish an LDD model. Reverse transcription-quantitative PCR was used to assess miR-125b-5p levels in human lumbar degenerative NP samples and IL-1β-treated NP cells. An interaction between miR-125b-5p and TP53-regulated inhibitor of apoptosis 1 (TRIAP1) was revealed by TargetScan 7.1 and dual-luciferase reporter assay. Protein levels of pro-inflammatory factors were determined using ELISA. Cell viability and apoptosis were evaluated by MTT and flow cytometry analysis, respectively. miR-125b-5p was markedly upregulated in both human lumbar degenerative NP specimens and IL-1β-treated NP cells. TRIAP1, which directly targets miR-125b-5p, was markedly downregulated in human lumbar degenerative NP specimens and IL-1β-treated NP cells. The levels of TNF-α and IL-6 were inhibited in IL-1β-treated NP cells transfected with miR-125b-5p inhibitor. Moreover, miR-125b-5p inhibitor increased NP cell viability, prevented apoptosis and repressed the apoptotic peptidase activating factor 1/caspase 9 pathway in IL-1β-treated NP cells. Thus, the present findings suggested that miR-125b-5p could regulate LDD by adjusting NP cell apoptosis and inflammatory responses via TRIAP1.

Abstract
Neurodegenerative diseases including Alzheimer's disease and Parkinson's disease are aging-associated diseases with irreversible damage of brain tissue. Oxidative stress is commonly detected in neurodegenerative diseases and related to neuronal injury and pathological progress. Exosome, one of the extracellular vesicles, is demonstrated to carry microRNAs (miRNAs) and build up a cell-cell communication in neurons. Recent research has found that exosomal miRNAs regulate the activity of multiple physiological pathways, including the oxidative stress response, in neurodegenerative diseases. Here, we review the role of exosomal miRNAs and oxidative stress in neurodegenerative diseases. Firstly, we explore the relationship between oxidative stress and neurodegenerative diseases. Secondly, we introduce the characteristics of exosomes and roles of exosome-related miRNAs. Thirdly, we summarized the crosstalk between exosomal miRNAs and oxidative stress in neurodegenerative diseases. Fourthly, we discuss the potential of exosomes to be a biomarker in neurodegenerative diseases. Finally, we summarize the advantages of exosome-based delivery and present situation of research on exosome-based delivery of therapeutic miRNA. Our work is aimed at probing and reinforcing the recognition of the pathomechanism of neurodegenerative diseases and providing the basis for novel strategies of clinical diagnosis and treatment.

Abstract
BACKGROUND Long-chain non-coding RNA (LncRNA) plays a key role in the biological processes of tumors. LncRNA-FTX has been the invasion of tumors. However, its function and mechanism in osteosarcoma have not been studied. METHODS qRT-PCR was measured the expression levels of FTX and miR-214-5p in osteosarcoma. The protein levels of SRY-related HMG box transcription factor 4 (SOX4) were detected by Western Blot. Cholecystokinin (CCK-8) assay, cell colony formation and Transwell assay, Annexin V-FITC/PI assay were analyzed the effects of FTX and miR-214-5p on cell proliferation, cell invasion and apoptosis. The relationship between FTX, miR-214-5p and SOX4 was analyzed by bioinformatics analysis and Luciferase. The tumor changes in mice were detected by vivo experiments in nude mice. RESULTS The expression levels of FTX were increased in osteosarcoma tissues and cell lines and negatively correlated with the expression levels of miR-214-5p. FTX could modulate the expression of miR-214-5p in osteosarcoma cell lines. sh-FTX inhibited the growth and metastasis of osteosarcoma. FTX could regulate the growth of osteosarcoma through miR-214-5p. The knockdown of miR-214-5p reversed the inhibitory effect of sh-FTX on osteosarcoma cell proliferation and growth in mice. Furthermore, FTX regulated the expression of SOX4 by acting as a sponge of miR-214-5p in osteosarcoma. CONCLUSION FTX could promote proliferation, invasion and inhibited apoptosis by regulating miR-214-5p/SOX4 axis in osteosarcoma, suggesting that FTX might be a potential target for osteosarcoma treatment.

Abstract
Recent advances in the biomedical importance of H2S have help us understand various cellular functions and pathophysiological processes from a new aspect. Specially, H2S has been demonstrated to play multiple roles in regulating cell behaviors, including cell survival, cell differentiation, cell senescence, cell hypertrophy, cell atrophy, cell metaplasia, and cell death, etc. H2S contributes to cell behavior changes via various mechanisms, such as histone modification, DNA methylation, non-coding RNA changes, DNA damage repair, transcription factor activity, and post-translational modification of proteins by S-sulfhydration, etc. In this review, we summarized the recent research progress on H2S signaling in control of cell behaviors and discussed the ways of H2S regulation of gene expressions. Given the key roles of H2S in both health and diseases, a better understanding of the regulation of H2S on cell behavior change and the underlying molecular mechanisms will help us to develop novel and more effective strategies for clinical therapy.

lncRNA-XIST protects the hypoxia-induced cardiomyocyte injury through regulating the miR-125b-hexokianse 2 axis. In Vitro Cell Dev Biol Anim 2020; 56:349-357.

Abstract
Ischemic injury in the heart is associated with low oxygen, leading to the damage of cardiomyocytes. The lncRNA-XIST is known to involve in post-ischemia myocardial remodeling. However, the roles and mechanism of XIST in the hypoxia-induced cardiomyocyte are still under investigation. Moreover, studies that elucidated the impaired glucose metabolism present new hallmark of ischemic cardiovascular injury. The objective of this study is to investigate the effects of lncRNA-XIST on cardiomyocyte injury under hypoxia. Here, we demonstrate that the XIST expressions of cardiomyocyte line, H9c2 were apparently suppressed by long-time hypoxia exposure under low glucose supply. On the contrary, miRNA-125b showed reverse expression pattern to XIST. We identified that XIST functioned as a ceRNA of miR-125b to downregulate its expression in both cell line and rat primary cardiomyocyte. Under low glucose supply, H9c2 cells exhibited increased susceptibility to hypoxia. We observed overexpression of XIST significantly elevated glycose metabolism rate under hypoxia, but overexpression of miR-125b inhibited glycose metabolism rate of cardiomyocyte under hypoxia. The glycolysis enzyme, hexokinase 2 (HK2) was validated as a direct target of miR-125b, which binds to the 3'-UTR region of HK2 mRNA in cardiomyocytes. Moreover, inhibition of miR-125b significantly protected the hypoxia-induced cardiomyocyte injury through restoration of glucose metabolism. Finally, we demonstrated that transfection of miR-125b in lncRNA-XIST overexpressed H9c2 cells effectively abolished the XIST-activated glucose metabolism and cardiomyocyte protection under hypoxia. The present study illustrates roles of the XIST-miR-125b-HK2 axis in the hypoxia-induced cardiomyocyte injury and proposes that maintaining glucose metabolism might be an effective approach for protection of cardiomyocyte injury.

Abstract
Objective This study was conducted to explore the association of microRNA (miR)‐125a and miR‐125b with acute respiratory distress syndrome (ARDS) risk and to investigate their correlation with clinical characteristics and prognosis in sepsis patients. Methods Totally 150 sepsis patients admitted to our hospital were consecutively enrolled and another 150 healthy subjects were enrolled as healthy controls (HCs). Their blood samples were collected for miR‐125a and miR‐125b detection by real‐time quantitative polymerase chain reaction. Besides, ARDS occurrence and 28‐day mortality were documented in all sepsis patients. Results MiR‐125a and miR‐125b relative expressions were increased in ARDS‐sepsis patients/non‐ARDS‐sepsis patients compared with HCs, while only miR‐125b but not miR‐125a was elevated in ARDS‐sepsis patients compared with non‐ARDS‐sepsis patients. Receiver operating characteristic (ROC) curve presented that miR‐125a (AUC: 0.650, 95%CI: 0.549‐0.750) and miR‐125b (AUC: 0.739, 95%CI: 0.653‐0.823) could differentiate ARDS‐sepsis patients from non‐ARDS‐sepsis patients, and miR‐125b was of increased predictive value compared with miR‐125a numerically. In sepsis patients, miR‐125a relative expression was positively associated with serum creatinine (Scr), chronic health evaluation (APACHE) II score, sequential organ failure assessment (SOFA) score, and miR‐125b was positively associated with Scr, C‐reactive protein (CRP), APACHE II score, SOFA score, and chronic obstructive pulmonary disease. All sepsis patients were categorized into survivors and deaths according to 28‐day mortality, and miR‐125b but not miR‐125a was upregulated in deaths compared with survivors. Conclusion Both of miR‐125a and miR‐125b predict ARDS risk, while only miR‐125b is of value in prognosis prediction in sepsis patients.

Evaluation of H 2S-producing enzymes in cerebrospinal fluid and its relationship with interleukin-6 and neurologic deficits in subarachnoid hemorrhage. Biomed Pharmacother 2019; 123:109722. [PMID: 31865144 DOI: 10.1016/j.biopha.2019.109722] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2019] [Revised: 11/19/2019] [Accepted: 11/27/2019] [Indexed: 01/13/2023] Open
Abstract
BACKGROUND AND PURPOSE Recent studies have suggested that H2S may be involved in the pathophysiology of subarachnoid hemorrhage (SAH). Endogenous H2S is mainly formed by cystathionine β-synthase (CBS), d-amino-acid oxidase (DAO), and 3-mercaptopyruvate sulfotransferase (3-MST) from the substrate cysteine in the central nervous system. In this study, we assessed the expression of CBS, 3-MST, and DAO in cerebrospinal fluid (CSF) from patients with SAH and rats and the expression in the rat brain. METHODS CSF samples were collected within 48 h of aneurysm rupture in SAH patients. The CBS, DAO and 3-MST levels in CSF were measured using Western blot analyses, and correlations with the inflammatory parameter Interleukin-6 (IL-6) were assessed. Six months after SAH, the clinical outcomes were assessed. RESULTS In human CSF samples, the CBS and DAO protein levels were detected and increased after SAH. However, 3-MST was not detected in the control group CSF but increased after SAH. Strong correlations were observed between the increasing levels of CBS, DAO, and 3-MST and IL-6 2 days after SAH. Furthermore, high CBS, 3-MST and DAO levels in the CSF samples were correlated with poor outcomes at 6 months after SAH onset. We also found that the expression of CBS, DAO and 3-MST in the rat CSF and brain (parietal cortex and hippocampus) increased following SAH. We detected strong correlations between the increases in CBS, 3-MST and IL-6 in the rat CSF and brain samples. CONCLUSIONS These results indicate that the upregulated expression of CBS, DAO and 3-MST after SAH was closely associated with the inflammatory response and neurological deficits after SAH.

Abstract
BACKGROUND AND AIMS Circulating microRNAs (miRNAs) have recently emerged as promising biomarkers for acute ischaemic stroke (AIS). However, the expression profiles of miRNAs in AIS patients receiving intravenous thrombolysis, and their associations with outcome have not been investigated. METHODS In a prospective cohort study, a total of 84 AIS patients, who received intravenous thrombolysis (21.4% received combined reperfusion therapy) and completed 3 month follow-up visits, were included. Favourable and unfavourable outcomes were defined as modified Rankin Scale (mRS) scores of 0-1 and 2-6, respectively. Plasma samples were collected at 24 h after thrombolysis. We used RNA sequencing to study miRNA profiles in 5 patients with unfavourable outcomes and 5 matched patients with favourable outcomes. Differentially expressed miRNAs were further validated in all cohorts using quantitative real-time polymerase chain reaction assays. RESULTS After identification and validation, we found that miR-124-3p, miR-125b-5p and miR-192-5p levels were higher in patients with unfavourable outcomes than in patients with favourable outcomes. Logistic regressions and receiver-operating characteristic curve analyses demonstrated that these altered miRNAs may function as predictive biomarkers for outcome in AIS patients receiving thrombolysis, whether combined with endovascular thrombectomy or not. In addition, miR-124-3p and miR-125b-5p were closely associated with stroke severity. CONCLUSIONS A set of circulating microRNAs (miR-124-3p, miR-125b-5p and miR-192-5p) are associated with unfavourable 3 month outcomes and might have clinical utility in AIS patients receiving thrombolysis.

miR-125b suppresses oral oncogenicity by targeting the anti-oxidative gene PRXL2A. Redox Biol 2019; 22:101140. [PMID: 30785086 PMCID: PMC6383183 DOI: 10.1016/j.redox.2019.101140] [Citation(s) in RCA: 54] [Impact Index Per Article: 10.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2018] [Revised: 01/22/2019] [Accepted: 02/08/2019] [Indexed: 12/11/2022] Open
Abstract
Oral squamous cell carcinoma (OSCC) is a globally prevalent malignancy. The molecular mechanisms of this cancer are not well understood and acquire elucidation. Peroxiredoxin like 2A (PRXL2A) has been reported to be an antioxidant protein that protects cells from oxidative stress. Our previous study identified an association between PRXL2A upregulation in OSCC and a worse patient prognosis. MicroRNAs (miRNAs) are small non-coding RNAs that are involved in the modulation of biological/pathological properties. The miR-125 family of genes drive pluripotent regulation across a wide variety of cancers. In this study, we identify the oncogenic eligibility of PRXL2A and clarify miR-125b as its upstream regulator. Downregulation of miR-125b can be observed in OSCC tumors. Lower miR-125b expression in tumors results in a worse patient prognosis at the relatively early stage. Reporter assays are able to validate that PRXL2A is a direct target of miR-125b. Exogenous miR-125b expression in OSCC cells results in increased oxidative stress, increased drug sensitivity, and suppressor activity that is paralleled by the knockout of PRXL2A gene. The suppressor activity of miR-125b is able to be rescued by PRXL2A, which suggests the existence of a miR-125b-PRXL2A regulatory axis that is part of OSCC pathogenesis. Nuclear factor-erythroid 2-related factor 2 (NRF2) was found to be a downstream effector of the miR-125b-PRXL2A cascade. As a whole, this study has pinpointed novel clues demonstrating that downregulation of miR-125b suppressor underlies upregulation of PRXL2A in OSCC, and this then protects the affected tumor cells from oxidative stress.
