[PMID: 38104486 DOI: 10.1016/j.atherosclerosis.2023.117424] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Revised: 12/01/2023] [Accepted: 12/07/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND AND AIMS Although calcific aortic valve disease (CAVD) is a common valvular disease among elderly populations and its incidence has markedly increased in recent decades, the pathogenesis of CAVD remains unclear. In this study, we explored the potential role of interleukin (IL)-22 and the underlying molecular mechanism in CAVD. METHODS AND RESULTS Our results showed that IL-22 was upregulated in calcific aortic valves from CAVD patients, and its main sources were CD3+ T cells and CD68+ macrophages. Human aortic valve interstitial cells (VICs) expressed the IL-22-specific receptor IL-22R1, and IL-22R1 expression also was elevated in calcified valves. Treatment of cultured human VICs with recombinant human IL-22 resulted in markedly increased expression of osteogenic proteins Runt-related transcription factor 2 (RUNX2) and alkaline phosphatase (ALP), as well as increased matrix calcium deposition. Moreover, siRNA silencing of IL-22R1 blocked the pro-osteogenic effect of IL-22 in VICs. In IL-22-treated VICs, we also observed increased phosphorylation of JAK3 and STAT3 and nuclear translocation of STAT3. Pretreatment with a specific JAK3 inhibitor, WHIP-154, or siRNA knockout of STAT3 effectively mitigated the IL-22-induced osteoblastic trans-differentiation of human VICs. CONCLUSIONS Together, these data indicate that IL-22 promotes osteogenic differentiation of VICs by activating JAK3/STAT3 signaling. Based on our results demonstrating a pro-osteogenic role of IL-22 in human aortic valves, pharmacological inhibition of IL-22 signaling may represent a potential strategy for alleviating CAVD.

Abstract
Aortic stenosis (AS) is a dynamic degenerative process that shares many pathophysiological features with atherogenesis, from initial proinflammatory calcification and focal thickening of the valve leaflets to obstruction of left ventricular outflow due to superimposed of severe calcification and immobilization of the valve leaflets. As the prevalence increases with age, AS is expected to become one of the most common heart diseases worldwide. In both obese and nonobese patients, persistent thickening of epicardial adipose tissue (EAT) is associated with a shift in its normal metabolic functions toward a dysmetabolic and proatherogenic phenotype that may impair the physiology of adjacent coronary arteries and promote the occurrence of coronary atherosclerosis. In tight analogy with atherosclerosis, recent clinical evidence indicates that EAT may also exert a deleterious role in promoting AS and contributing to myocardial dysfunction, leading to increased health risk for elderly patients with AS and an economic burden on the health care system. This review discusses the clinical and pathologic evidence for the association between EAT and AS and concomitant left ventricular hypertrophy, and provides new insights for the future direction of AS diagnosis and treatment.

Abstract
Calcific aortic valve disease (CAVD) is an aging related disease characterized by inflammation and fibrocalcific remodeling. IL-17A is a key cytokine associated with pathophysiology of inflammatory and fibrotic disease. Previous studies showed accumulation of IL-17A-producing T helper lymphocytes in human calcified aortic valves and significantly elevated IL-17RA expression in calcified valves. However, the role of IL-17A signaling in the initiation and development of CAVD is still unclear. In this study, by analyzing public transcriptome databases, we found that IL-17A-IL-17RA signaling is activated in calcified valves. Gene expression analysis revealed significantly increased IL-17A, IL-17RA, and RUNX2 expression in calcified human aortic valves compared to in non-calcified valves, and the expression of IL-17A and IL-17RA were positively correlated with RUNX2 expression. A 5/6 nephrectomy was performed in Apoe-/- (Apoe knockout) mice to establish a CAVD mouse model. IL-17A-neutralizing antibodies significantly reduced valve calcium deposition and decreased expression of RUNX2 in aortic valves. Immunofluorescence staining of human aortic valves and qRT-PCR analysis of primary aortic valve cells revealed abundant expression of IL-17RA in valvular endothelial cells (VECs). RNA sequencing indicated that IL-17A promoted the activation of inflammatory signaling pathways in VECs. Furthermore, qRT-PCR and cytometric bead array analysis confirmed that IL-17A promoted the expression or secretion of inflammatory cytokines IL-6 and IL-1β, chemokines CXCL2 and CXCL8, and fibrosis-related gene COL16A1. Our findings indicate that elevated IL-17A in CAVD may promote valve inflammation, fibrosis, and calcification by inducing endothelial activation and inflammation. Targeting IL-17A-IL-17RA signaling may be a potential therapeutic strategy for CAVD.

Abstract
Vascular calcification is defined as an inappropriate accumulation of calcium depots occurring in soft tissues, including the vascular wall. Growing evidence suggests that vascular calcification is an actively regulated process, sharing similar mechanisms with bone formation, implicating both inhibitory and inducible factors, mediated by osteoclast-like and osteoblast-like cells, respectively. This process, which occurs in nearly all the arterial beds and in both the medial and intimal layers, mainly involves vascular smooth muscle cells. In the vascular wall, calcification can have different clinical consequences, depending on the pattern, localization and nature of calcium deposition. Nuclear receptors are transcription factors widely expressed, activated by specific ligands that control the expression of target genes involved in a multitude of pathophysiological processes, including metabolism, cancer, inflammation and cell differentiation. Some of them act as drug targets. In this review we describe and discuss the role of different nuclear receptors in the control of vascular calcification.

Abstract
Objectives Cervical cancer, the most common female cancer after breast cancer, is
typically treated using radiotherapy. However, pelvic radiotherapy can cause
irreversible damage to the vagina, seriously affecting patients’ quality of
life. In this study, protein scaffolds loaded with rat adipose-derived
mesenchymal stem cells (ADSCs) were implanted into irradiated tissue to
assess their healing potential. Methods We established a rat model of radiation-induced vaginal injury. Complexes
(consisting of protein scaffolds loaded with ADSCs) were implanted into
injury sites. Histological analysis were used to assess regeneration of the
vaginal epithelium. RNA sequencing was used to study the therapeutic
mechanism of the complexes. Results The complexes promoted vaginal epithelial cell regeneration, vaginal tissue
repair and improved vaginal stenosis and contracture. Compared with rats
transplanted with ADSCs, rats transplanted with complexes achieved better
therapeutic effects. Conclusions Protein scaffold-ADSC complexes had a beneficial therapeutic effect on
radiation-induced vaginal injury in rats and may serve as the basis of a
novel therapeutic approach for radiation dermatitis.

Abstract
OBJECTIVE Interleukin (IL)-33 is a mediator in the pathogenesis of several inflammatory diseases. Its receptor, ST2, is overexpressed in nonrheumatic aortic valve stenosis (NR-AS). This study compared smooth muscle α-actin (α-SMA), osteopontin (OPN), and suppression of tumorigenicity 2 (ST2) expression between specimens from fibrotic and calcific stages of NR-AS and observed the effects and mechanisms of phenotypic transition of porcine valvular interstitial cells (VICs) in the presence of IL-33. METHODS Peripheral blood IL-1 family mRNA and protein levels in NR-AS patients and healthy adults were quantified by real-time quantitative polymerase chain reaction (RT-qPCR) and enzyme-linked immunosorbent assay. Immunohistochemistry and immunofluorescence were used to detect the expression and coexpression of α-SMA, OPN, and ST2 in NR-AS specimens. Porcine VICs were stimulated with IL-33, IL-33+SB203580, or IL-33+SC75741. mRNA and protein expression levels of porcine VICs were detected by RT-qPCR and western blot. RESULTS The mRNA and protein levels of IL-33 and sST2 in peripheral blood of NR-AS patients were higher than those in healthy adults. Immunohistochemistry and immunofluorescence showed higher expression of α-SMA, OPN, and ST2 in the calcific stage of NR-AS than in the fibrotic stage. Coexpression of ST2/α-SMA or ST2/OPN was found only in the calcific stage. Nuclear factor (NF)-κB and p38 mitogen-activated protein kinase (MAPK) phosphorylation levels were associated with IL-33-induced porcine VIC differentiation into myofibroblasts and osteoblasts, respectively. IL-33 stimulation also promoted the coexpression of ST2/OPN or α-SMA/OPN/ST2. CONCLUSION IL-33 might be a potential biomarker for NR-AS. IL-33-induced porcine VIC differential phenotypic transition and differentiation into myofibroblasts and osteoblasts were dependent on the NF-κB and p38 MAPK signaling pathways, respectively.

Abstract
Osteoblastic differentiation of aortic valve interstitial cells (AVICs) is the central process in the development of calcific aortic valve disease (CAVD). Metformin is a widely used first-line antidiabetic drug, and recently, pleiotropic benefits of metformin beyond hypoglycemia have been reported in the cardiovascular system. Here, we examined the effect of metformin on the osteoblastic differentiation of human AVICs. Our results showed that metformin ameliorated TGF-β1-induced production of osteogenic proteins Runx2 and osteopontin as well as calcium deposition in the cultured human AVICs. Experiments using AICAR, Compound C and AMPKα siRNA showed that the beneficial effect of metformin on TGF-β1-induced osteoblastic differentiation of human AVICs was mediated by AMPKα. Moreover, metformin inhibited the TGF-β1-induced activation of β-catenin, and β-catenin siRNA blocked TGF-β1-induced osteoblastic differentiation of AVICs. Smad2/3 and JNK were phosphorylated to promote the TGF-β1-induced activation of β-catenin and osteoblastic differentiation of AVICs, and metformin also alleviated TGF-β1-induced activation of Smad2/3 and JNK. In conclusion, our results suggest a beneficial effect of metformin based on the prevention of osteoblastic differentiation of human AVICs via inhibition of β-catenin, which indicates the therapeutic potential of metformin for CAVD.

Abstract
Alpha-lipoic acid (ALA) is a pleiotropic molecule with antioxidant and anti-inflammatory properties, of which the effects are exerted through the modulation of NF-kB. This nuclear factor, in fact, modulates different inflammatory cytokines, including IL-1b and IL-6, in different tissues and cell types. We recently showed that IL-1b and IL-6 DNA methylation is modulated in the brain of Alzheimer's disease patients, and that IL-1b expression is associated to DNA methylation in the brain of patients with tuberous sclerosis complex. These results prompted us to ask whether ALA-induced repression of IL-1b and IL-6 was dependent on DNA methylation. Therefore, we profiled DNA methylation in the 5'-flanking region of the two aforementioned genes in SK-N-BE human neuroblastoma cells cultured in presence of ALA 0.5 mM. Our experimental data pointed out that the two promoters are hypermethylated in cells supplemented with ALA, both at CpG and non-CpG sites. Moreover, the observed hypermethylation is associated with decreased mRNA expression and decreased cytokine release. These results reinforce previous findings indicating that IL-1b and IL-6 undergo DNA methylation-dependent modulation in neural models and pave the road to study the epigenetic mechanisms triggered by ALA.

Abstract
Untreated, severe, symptomatic aortic stenosis is associated with a dismal prognosis. The only treatment shown to improve survival is aortic valve replacement; however, before symptoms occur, aortic stenosis is preceded by a silent, latent phase characterized by a slow progression at the molecular, cellular, and tissue levels. In theory, specific medical therapy should halt aortic stenosis progression, reduce its hemodynamic repercussions on left ventricular function and remodeling, and improve clinical outcomes. In the present report, we performed a systematic review of studies focusing on the medical treatment of patients with aortic stenosis. Lipid-lowering therapy, antihypertensive drugs, and anticalcific therapy have been the main drug classes studied in this setting and are reviewed in depth. A critical appraisal of the preclinical and clinical evidence is provided, and future research avenues are presented.
