Abstract
MicroRNAs are crucial in the development of myocardial remodeling in hypertension. Low miR-1929-3p expression induced by murine cytomegalovirus (MCMV) infection is closely related to hypertensive myocardial remodeling. This study investigated the molecular mechanism of miR-1929-3p-induced myocardial remodeling after MCMV infection. We modeled MCMV-infected mouse cardiac fibroblasts (MMCFs) as the primary cell model. First, MCMV infection reduced the expression of miR-1929-3p and increased the mRNA and protein expression of its target gene endothelin receptor type A (ETAR) in mouse cardiac fibroblasts (MCFs), which demonstrated an internal relationship with myocardial fibrosis (MF) based on high proliferation, phenotypic transformation (α-SMA), and collagen expression in MMCFs. The transfection of the miR-1929-3p mimic downregulated the high expression of ETAR and alleviated these adverse effects in MMCFs. Inversely, these effects were exacerbated by the miR-1929-3p inhibitor. Second, the transfection of endothelin receptor type A over-expressed adenovirus (adETAR) reversed these positive effects of the miR-1929-3p mimic on MF improvement. Third, the transfection of adETAR exhibited a strong inflammatory response in MMCFs with increased expression of NOD-like receptors pyrin domain containing 3 (NLRP3) and increased secretion of interleukin-18. However, we found that the ETAR antagonist BQ123 and the selected NLRP3 inflammasome inhibitor MCC950 effectively eliminated the inflammatory response induced by both MCMV infection and miR-1929-3p inhibitor. Moreover, the MCF supernatant was related to cardiomyocyte hypertrophy. Our findings suggest that MCMV infection promotes MF by inducing the downregulation of miR-1929-3p and the high expression of ETAR, which activates NLRP3 inflammasomes in MCFs.

Abstract
Herpesviruses are ubiquitous pathogens that establish lifelong, latent infections in their host. Spontaneous reactivation of herpesviruses is often asymptomatic or clinically manageable in healthy individuals, but reactivation events in immunocompromised or immunosuppressed individuals can lead to severe morbidity and mortality. Moreover, herpesvirus infections have been associated with multiple proliferative cardiovascular and post-transplant diseases. Herpesviruses encode viral G protein-coupled receptors (vGPCRs) that alter the host cell by hijacking cellular pathways and play important roles in the viral life cycle and these different disease settings. In this review, we discuss the pharmacological and signaling properties of these vGPCRs, their role in the viral life cycle, and their contribution in different diseases. Because of their prominent role, vGPCRs have emerged as promising drug targets, and the potential of vGPCR-targeting therapeutics is being explored. Overall, these vGPCRs can be considered as attractive targets moving forward in the development of antiviral, cancer, and/or cardiovascular disease treatments. SIGNIFICANCE STATEMENT: In the last decade, herpesvirus-encoded G protein-coupled receptors (GPCRs) have emerged as interesting drug targets with the growing understanding of their critical role in the viral life cycle and in different disease settings. This review presents the pharmacological properties of these viral receptors, their role in the viral life cycle and different diseases, and the emergence of therapeutics targeting viral GPCRs.

miR-1929-3p Overexpression Alleviates Murine Cytomegalovirus-Induced Hypertensive Myocardial Remodeling by Suppressing Ednra/NLRP3 Inflammasome Activation. BIOMED RESEARCH INTERNATIONAL 2020; 2020:6653819. [PMID: 33457411 PMCID: PMC7787724 DOI: 10.1155/2020/6653819] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/10/2020] [Accepted: 12/12/2020] [Indexed: 12/18/2022]
Abstract
MicroRNAs (miRNAs) play crucial roles in the development of essential hypertension (EH). Previously, we found that the expression of miR-1929-3p was decreased in C57BL/6 mice with hypertension induced by murine cytomegalovirus (MCMV). In this study, we explored the role of miR-1929-3p in hypertension myocardial remodeling in MCMV-infected mice. First, we measured MCMV DNA and host IgG and IgM after infection and determined the expression of miR-1929-3p and its target gene endothelin A receptor (Ednra) mRNA in the myocardium of mice. Then, we performed invasive blood pressure (BP) monitoring. Heart-to-body weight ratio (HW/BW%), along with mRNA levels of B-type natriuretic peptide (BNP) and beta myosin heavy chain (β-MHC), revealed myocardial remodeling. Hematoxylin/eosin and Masson's trichrome staining indicated morphological changes in the myocardium. Cardiac function was assessed via echocardiography. Moreover, MCMV-infected mice were injected with recombinant adeno-associated virus- (rAAV-) miR-1929-3p overexpression vector. Immunohistochemistry and western blotting showed the expression of Ednra and the activation of NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasome. And enzyme-linked immunosorbent assay (ELISA) revealed the concentrations of endothelin-1 (ET-1), interleukin-1β (IL-1β), and interleukin-18 (IL-18). In this study, we found that decreased expression of miR-1929-3p in MCMV-infected mice induced high BP and further development of myocardial remodeling cardiac function injury through increased expression of Ednra. Strikingly, overexpression of miR-1929-3p ameliorated these pathological changes of the heart. The positive effect was shown to be associated with inhibition of NLRP3 inflammasome activation and decreased expression of key proinflammatory cytokine IL-1β. Collectively, these results indicate that miR-1929-3p overexpression may effectively alleviate EH myocardial remodeling by suppressing Ednra/NLRP3 inflammasome activation in MCMV-infected mice.
