The Immunomodulatory Role of Microbiota in Rheumatic Heart Disease: What Do We Know and What Can We Learn from Other Rheumatic Diseases? MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1629. [PMID: 37763748 PMCID: PMC10536446 DOI: 10.3390/medicina59091629] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 09/04/2023] [Accepted: 09/05/2023] [Indexed: 09/29/2023]
Abstract
Rheumatic heart disease (RHD) represents a serious cardiac sequela of acute rheumatic fever, occurring in 30-45% of patients. RHD is multifactorial, with a strong familial predisposition and known environmental risk factors that drive loss of immunological tolerance. The gut and oral microbiome have recently been implicated in the pathogenesis of RHD. Disruption of the delicate balance of the microbiome, or dysbiosis, is thought to lead to autoimmune responses through several different mechanisms including molecular mimicry, epitope spreading, and bystander activation. However, data on the microbiomes of RHD patients are scarce. Therefore, in this comprehensive review, we explore the various dimensions of the intricate relationship between the microbiome and the immune system in RHD and other rheumatic diseases to explore the potential effect of microbiota on RHD and opportunities for diagnosis and treatment.

Zhu J, Zhu N, Xu J. miR‑101a‑3p overexpression prevents acetylcholine‑CaCl 2‑induced atrial fibrillation in rats via reduction of atrial tissue fibrosis, involving inhibition of EZH2. Mol Med Rep 2021; 24:740. [PMID: 34435649 PMCID: PMC8404104 DOI: 10.3892/mmr.2021.12380] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/18/2021] [Accepted: 07/09/2021] [Indexed: 11/23/2022] Open
Abstract
Atrial fibrillation (AF), a clinically common heart arrhythmia, can result in left ventricular hypofunction, embolism and infarction. MicroRNA (miR)‑101a‑3p is lowly expressed in atrial tissues of patients with AF, but its role in AF remains unknown. In the present study, an AF model in rats was established via intravenous injection of acetylcholine (Ach)‑CaCl2. The downregulation of miR‑101a‑3p and upregulation of enhancer of zeste 2 homolog 2 (EZH2) were observed in AF model rats, indicating the involvement of miR‑101a‑3p and EZH2 in AF development. To study the effect of miR‑101a‑3p on AF in vivo, AF model rats were intramyocardially injected with lentivirus expressing miR‑101a‑3p. Electrocardiogram analysis identified that miR‑101a‑3p overexpression restored disappeared P wave and R‑R interphase changes in Ach‑CaCl2‑induced rats. Overexpression of miR‑101a‑3p also increased the atrial effective refractory period, reduced AF incidence and shortened duration of AF. Histological changes in atrial tissues were observed after H&E and Masson staining, which demonstrated that miR‑101a‑3p reduced atrial remodeling and fibrosis in AF model rats. Moreover, EZH2 expression was downregulated in atrial tissues by miR‑101a‑3p induction. Immunohistochemistry for collagen Ⅰ and collagen III revealed a reduction in atrial collagen synthesis following miR‑101a‑3p overexpression in AF model rats. Additionally, miR‑101a‑3p lowered the expression of pro‑fibrotic biomarkers, including TGF‑β1, connective tissue growth factor, fibronectin and α‑smooth muscle actin. The luciferase reporter assay results also indicated that EZH2 was a target gene of miR‑101a‑3p. Taken together, it was found that miR‑101a‑3p prevented AF in rats possibly via inhibition of collagen synthesis and atrial fibrosis by targeting EZH2, which provided a potential target for preventing AF.

[PMID: 32072912 DOI: 10.2174/1567202617666200211113016] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2019] [Revised: 01/06/2020] [Accepted: 01/11/2020] [Indexed: 11/22/2022]
Abstract
BACKGROUND Myocardial Infarction (MI), a kind of heart deficiency, is the main cause of death and disability. Autophagy, a metabolic process for the degradation of damaged proteins or organelles, is important for cardiac functions and regulated by several miRNAs including miRNA- 101. The aim of this research was to investigate the effects of miR-101 in myocardial infarctioninduced injury and the related mechanisms. METHODS MI model was induced by ligation of the left coronary artery. The in vitro model was established by hypoxia-induced H9c2 cells (rat myocardial cells). The overexpression of miR-101 was achieved by transfection. The expression of associated proteins was analyzed by Western blotting. The level of miR-101 was analyzed by reverse transcription-polymerase chain reaction (RTPCR). The target genes for miR-101 and the target sites were analyzed by TargetScan. RESULTS The results showed that miR-101 was decreased in MI mice (P<0.01). Autophagy and apoptosis were increased in MI-induced injury (in vivo) and in hypoxia treated myocardial cells (in vitro) (P<0.01). miR-101 overexpression inhibited the increase of autophagy and apoptosis in mice and myocardial cells (P<0.01). DDIT4 was a target gene of miR-101 and expressed increasingly in MI-induced injury mice and hypoxia treated myocardial cells. miR-101 could negatively regulate the expression of DDIT4. CONCLUSION This research suggested that miR-101 attenuated- MI-induced injury by targeting DDIT4 to regulate autophagy, which indicated that miR-101 or DDIT4 may be potential therapeutic targets for heart injury.

Abstract
Toll-like receptors (TLRs) are a large group of pattern recognition receptors which are involved in the regulation of innate immune responses. Based on the interplay between TLRs and adapter molecules, two distinctive signaling cascades, namely the MyD88-dependent and TRIF-dependent pathways have been recognized. TLRs are involved in the development of a wide variety of diseases including cancer and autoimmune disorders. A large body of evidence has shown interaction between two classes of non-coding RNAs, namely microRNAs (miRNAs) and long noncoding RNAs (lncRNAs). These interactions have prominent roles in the pathogenesis of several disorders including infectious disorders, autoimmune conditions and neoplastic disorders. This review aims at description of the interaction between these non-coding RNAs and TLRs.

miRNA-1183-targeted regulation of Bcl-2 contributes to the pathogenesis of rheumatic heart disease. Biosci Rep 2021; 40:226700. [PMID: 33073840 PMCID: PMC7607189 DOI: 10.1042/bsr20201573] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 10/13/2020] [Accepted: 10/14/2020] [Indexed: 02/06/2023] Open
Abstract
To determine whether up-regulation of miR-1183 targeting the gene for anti-apoptotic factor, B-cell lymphoma 2 (BCL-2) contributes to apoptosis in patients with rheumatic heart disease (RHD). Peripheral blood samples were isolated for miR-1183 characterization. The function of miRNA-1183 in RHD using miRNA mimic on PBMCs and THP-1 cell models. The binding of miR-1183 and Bcl-2 gene was confirmed by luciferase activity test. We also measured expression levels of BCL-2 in heart valve tissue from patients with RHD using ELISA and immunohistochemistry. In silico analysis and reporter gene assays indicated that miR-1183 directly targets the mRNA encoding BCL-2. It is found that miR-1183 binds directly to the 3'UTR of the BCL-2 mRNA and down-regulates the mRNA and protein levels of BCL-2. Overexpression of miR-1183 in RHD patients and cell lines down-regulated BCL-2 expression and induced apoptosis. With the progression of the disease, the expression of BCL-2 in the heart valve tissue of patients with RHD decreased. MiRNA-1183 is up-regulated in RHD and induces cardiac myocyte apoptosis through direct targeting and suppression of BCL-2, both of which might play important roles in RHD pathogenesis. During the compensatory period of RHD, up-regulated miR-1183 destroyed the balance of apoptosis proteins (Bax and BAK) in Bcl-2 family, enhance the apoptosis cascade reaction and reduce the anti apoptosis effect. The significantly higher expression levels of miR-1183 appear to play distinct roles in RHD pathogenesis by regulation BCL-2, possibly affecting myocardial apoptosis and remodeling in the context of RHD.

Abstract
Intervertebral disc degeneration (IVDD) is a common cause of low back pain. This study is aimed at investigating the role of microRNAs (miRNAs) in regulating human nucleus pulposus (NP) cell injury induced by tumor necrosis factor- (TNF-) α in IVDD. In this study, we induced NP cells with 20 ng/mL TNF-α in vitro, which promoted the obvious apoptosis of NP cells and the activation of nuclear transcription factor (NF)-κB. In contrast, using the specific NF-κB inhibitor BAY 11-7082 to treat cells greatly impaired the activation of NF-κB and increased the sensitivity of NP cells to TNF-α-induced apoptosis. Moreover, both TNF-α and BAY 11-7082 treatments were associated with marked miRNA dysregulation, with miR-502 being upregulated by TNF-α treatment and downregulated by BAY 11-7082 treatment, respectively. And the overexpression of miR-502 enhanced NF-κB activation and suppressed apoptosis of human NP cells induced by TNF-α, whereas the opposite was observed following miR-502 inhibition. Last, through bioinformatic analyses and luciferase reporter gene experiments, we identified TRAF2, an important activator of NF-κB, as a miR-502 target gene. Similarly, siRNA-mediated knockdown of the TRAF2 expression also suppressed TNF-α-induced apoptosis and enhanced NF-κB activation. Our findings provide evidence indicating that miR-502 is a key regulator of apoptosis of human NP cells induced by TNF-α by targeting TRAF2 and activating NF-κB.

Abstract
Astragaloside IV (AS/IV) is one of the extracted components from the traditional Chinese medicine Astragalus which has been demonstrated to have potential capacity for anti-inflammation activity and for treating cardiovascular disease. Our purpose was to determine the function and underlying molecular mechanism of AS/IV in hypoxia/reoxygenation (H/R) injured in cardiomyocytes. Differentially expressed genes (DEGs) were screened using bioinformatic analysis, and the molecular targeting relationship was verified by the dual-luciferase report system. H/R injured cardiomyocytes were employed to explore the effect of AS/IV. QRT-PCR and Western blot analysis were applied to detect the expression of mRNA and proteins, respectively. Additionally, superoxide dismutase (SOD), lactic dehydrogenase (LDH) and MDA (malondialdehyde) levels were detected to determine the oxidative damage. Cell viability was assessed by CCK-8, and flow cytometry was used to evaluate cell apoptosis ratio. TGFBR1 and TLR2 were selected as DEGs. Additionally, AS/IV could enhance cell proliferation and upregulated miR-101a expression, which suppressed TGFBR1 and TLR2 expression in H/R injured cardiomyocytes. Moreover, the results of Western blot exhibited that the downstream genes (p-ERK and p-p38) in the MAPK signaling pathway were suppressed, which meant AS/IV could inhibit this pathway in H/R injured cardiomyocytes. Overall, this study demonstrated AS/IV could attenuate H/R injury in human cardiomyocytes via the miR-101a/TGFBR1/TLR2/MAPK signaling pathway axis, which means that it could serve as a possible alternate for H/R treatment.

Abstract
Renal fibrosis denotes a common complication of diabetic nephropathy and is a predominant cause of end-stage renal disease. Despite the association between microRNAs (miRNAs or miRs) and renal fibrosis, miRNAs have been reported to play a vital role in the development of chronic renal fibrosis. Therefore, the aim of the present study was to investigate the possible function of miR-101a in chronic renal fibrosis. Initially, microarray-based gene expression profiling of renal fibrosis was employed to screen the differentially expressed genes. An in vivo mouse model of chronic renal fibrosis induced by a unilateral ureteral obstruction (UUO) and an in vitro cell model induced by aristolochic acid (AA) were constructed. miR-101a expression was examined using a fluorescence in situ hybridization (FISH) assay and quantitative reverse transcription polymerase chain reaction (qRT-PCR). Then, the interaction between miR-101a and KDM3A was identified using an online website combined with a dual-luciferase reporter assay. Finally, gain- and loss-of-function experiments were conducted to elucidate the effect of miR-101a on the expression of Col1a1, fibronectin, α-smooth muscle actin (α-SMA), and YAP-TGF-β (transforming growth factor β)-Smad signaling pathway-related genes, as well as the degree of renal fibrosis. miR-101a was poorly expressed while KDM3A was robustly induced in chronic renal fibrosis tissues and cells. In addition, miR-101a could target and downregulate KDM3A expression, which led to elevated TGIF1, inhibited expression of Collagen I (Col1a1), fibronectin, α-SMA, YAP1, and TGF-β2 along with the extent of Smad2/3 phosphorylation, as well as delayed renal fibrosis degree. Besides, overexpressed YAP/TGF-β2 or inhibited TGIF1 partially restored the inhibitory effect of miR-101a on chronic renal fibrosis. Taken together, miR-101a could potentially slow down chronic renal fibrosis by the inactivation of the YAP-TGF-β-Smad signaling pathway via KDM3A, highlighting the potential of miR-101a as a therapeutic target for chronic renal fibrosis treatment.

Abstract
Autoimmunity is involved in the valvular damage caused by rheumatic heart disease (RHD). Increased evidence has linked microRNAs (miRNAs/miRs) to autoimmune disease. Signal transducer and activator of transcription 3 (STAT3) and sphingosine-1-phosphate receptor 1 (S1PR1) and suppressor of cytokine signaling 1 (SOCS1) have been widely studied for their roles in autoimmunity and inflammation. Thus, the current study aims to investigate the role played by miR-155-5p in RHD-induced valvular damage via the S1PR1, SOCS1/STAT3 and interleukin (IL)-6/STAT3 signaling pathways. An RHD rat model was induced by inactivated Group A streptococci and complete Freund's adjuvant. A recombinant adeno-associated virus (AAV-miR155-inhibitor) was used to inhibit the expression of miR-155-5p in the heart. Inflammation and fibrosis were assessed by hematoxylin and eosin staining and Sirius red staining. The expression of miR-155-5p in valvular tissues and serum exosomes was detected by reverse transcription-quantitative PCR. S1PR1, SOCS1, STAT3, phosphorylated STAT3, IL-6 and IL-17 protein expression was detected by western blotting and immunohistochemistry. The relationships between miR-155-5p and S1PR1 and SOCS1 were detected by dual luciferase assays. Cytokine concentrations were measured by ELISA. The expression of miR-155-5p in valve tissues and serum exosomes was increased along with decreased S1PR1 and activated SOCS1/STAT3 signaling in the RHD model. The expression of IL-6 and IL-17 was increased in the valves and the serum. Dual luciferase assays showed that miR-155-5p directly targeted S1PR1 and SOCS1. Inhibition of valvular miR-155-5p through AAV pretreatment increased S1PR1 expression and inhibited activation of the SOCS1/STAT3 signal pathway as a result of attenuated valvular inflammation and fibrosis as well as a decrease in IL-6 and IL-17 in the valves and serum. These results suggest that inhibition of miR-155-5p can reduce RHD-induced valvular damage via the S1PR1, SOCS1/STAT3 and IL-6/STAT3 signaling pathways.

Abstract
MicroRNAs (miRNAs) have been reported to be of great importance in a wide range of physiological and pathological processes, including acute coronary syndrome (ACS). However, the exact role of miRNAs in the pathogenesis of ACS has not been fully elucidated. In this study, we found that miR-101 was significantly upregulated in the serum samples of patients with acute coronary syndrome compared with healthy controls. In human umbilical vein endothelial cells (HUVECs), the overexpression of miR-101 drastically promoted cell apoptosis and inhibited cell migration. Mechanistically, miR-101 repressed the expression of CHD5 by targeting its 3'-untranslated region (3'UTR). The silencing of CHD5 also induced cell apoptosis and suppressed cell migration in HUVECs. Taken together, our findings suggest that the miR-101-CHD5 axis may play an important role in the biological behaviors of endothelial cells during the pathogenesis of ACS and may afford an effective diagnostic marker and a powerful therapy for this disease.
