Abstract
The ongoing trend of rapid aging of the global population has unavoidably resulted in an increase in aging-related diseases. There is an immense amount of interest in the scientific community for the identification of molecular targets that may effectively mitigate the process of aging and aging-related diseases. The enzyme Topoisomerase IIβ (TOP2B) plays a crucial role in resolving the topological challenges that occur during DNA-related processes. It is believed that the disruption of TOP2B function contributes to the aging of cells and tissues, as well as the development of age-related diseases. Consequently, targeting TOP2B appears to be a promising approach for interventions aimed at mitigating the effects of aging. This review focuses on recent advancements in the understanding of the role of TOP2B in the processing of aging and aging-related disorders, thus providing a novel avenue for the development of anti-aging strategies.

Abstract
Vascular calcification refers to the pathological deposition of calcium and phosphate minerals into the vasculature. It is prevalent in atherosclerosis, ageing, type 2 diabetes mellitus and chronic kidney disease, thus, increasing morbidity and mortality from these conditions. Vascular calcification shares similar mechanisms with bone mineralization, with smooth muscle cells playing a critical role in both processes. In the last decade, a variety of microRNAs have been identified as key regulators for the differentiation, phenotypic switch, proliferation, apoptosis, cytokine production and matrix deposition in vascular smooth muscle cells during vascular calcification. Therefore, this review mainly discusses the roles of microRNAs in the pathophysiological mechanisms of vascular calcification in smooth muscle cells and describes several interventions against vascular calcification by regulating microRNAs. As the exact mechanisms of calcification remain not fully elucidated, having a better understanding of microRNA involvement in vascular calcification may give impetus to development of novel therapeutics for the control and treatment of vascular calcification.

TL1A inhibits atherosclerosis in apoE-deficient mice by regulating the phenotype of vascular smooth muscle cells. J Biol Chem 2020; 295:16314-16327.

Abstract
TNF ligand-related molecule 1A (TL1A) is a vascular endothelial growth inhibitor to reduce neovascularization. Lack of apoE a expression results in hypercholesterolemia and atherosclerosis. In this study, we determined the precise effects of TL1A on the development of atherosclerosis and the underlying mechanisms in apoE-deficient mice. After 12 weeks of pro-atherogenic high-fat diet feeding and TL1A treatment, mouse aorta, serum, and liver samples were collected and used to assess atherosclerotic lesions, fatty liver, and expression of related molecules. We found that TL1A treatment significantly reduced lesions and enhanced plaque stability. Mechanistically, TL1A inhibited formation of foam cells derived from vascular smooth muscle cells (VSMCs) but not macrophages by activating expression of ABC transporter A1 (ABCA1), ABCG1, and cholesterol efflux in a liver X receptor-dependent manner. TL1A reduced the transformation of VSMCs from contractile phenotype into synthetic phenotypes by activating expression of contractile marker α smooth muscle actin and inhibiting expression of synthetic marker osteopontin, or osteoblast-like phenotype by reducing calcification. In addition, TL1A ameliorated high-fat diet-induced lipid metabolic disorders in the liver. Taken together, our work shows that TL1A can inhibit the development of atherosclerosis by regulating VSMC/foam cell formation and switch of VSMC phenotypes and suggests further investigation of its potential for atherosclerosis treatment.

Abstract
MicroRNAs (miRNAs) are key modulators of post-transcriptional gene regulation in a plethora of processes, including actin–myosin cytoskeleton dynamics. Recent evidence points to the widespread effects of miRNAs on actin–myosin cytoskeleton dynamics, either directly on the expression of actin and myosin genes or indirectly on the diverse signaling cascades modulating cytoskeletal arrangement. Furthermore, studies from various human models indicate that miRNAs contribute to the development of various human disorders. The potentially huge impact of miRNA-based mechanisms on cytoskeletal elements is just starting to be recognized. In this review, we summarize recent knowledge about the importance of microRNA modulation of the actin–myosin cytoskeleton affecting physiological processes, including cardiovascular function, hematopoiesis, podocyte physiology, and osteogenesis.

Abstract
Atherosclerosis is one of the main causes of cardiovascular diseases. Our previous study indicated that a type of peroxidase derived from foxtail millet bran (FMBP) had prominent antitumor activities. In the present study, we found that FMBP had potential antiatherosclerosis effects. The results showed that FMBP treatment strongly suppressed lipid phagocytosis in both HASMCs and THP-1 cells by 52% and 49%, respectively. Further, FMBP significantly inhibited HASMCs migration by promoting transformation of HASMCs from synthetic to contractile, leading to the decrease of lipid phagocytosis. Simultaneously, FMBP repressed lipid uptake by reducing the expression of CD36 in THP-1 cells. In addition, FMBP reduced the secretion of inflammatory factor IL-1β by inhibiting the expression of STAT3 in THP-1 cells. Interestingly, FMBP also had the same effects in models of atherosclerosis constructed with ApoE-/- mice, including decreased aortic lesion area, repressed aortic sinus CD36 and STAT3 expression, and elevated serum HDL-C concentration. Collectively, these results indicate that FMBP has great potential in preventing the development of atherosclerosis.

The Epigenetic Landscape of Vascular Calcification: An Integrative Perspective. Int J Mol Sci 2020; 21:ijms21030980.

Abstract
Vascular calcification (VC) is an important complication among patients of advanced age, those with chronic kidney disease, and those with diabetes mellitus. The pathophysiology of VC encompasses passive occurrence of physico-chemical calcium deposition, active cellular secretion of osteoid matrix upon exposure to metabolically noxious stimuli, or a variable combination of both processes. Epigenetic alterations have been shown to participate in this complex environment, through mechanisms including DNA methylation, non-coding RNAs, histone modifications, and chromatin changes. Despite such importance, existing reviews fail to provide a comprehensive view of all relevant reports addressing epigenetic processes in VC, and cross-talk between different epigenetic machineries is rarely examined. We conducted a systematic review based on PUBMED and MEDLINE databases up to 30 September 2019, to identify clinical, translational, and experimental reports addressing epigenetic processes in VC; we retrieved 66 original studies, among which 60.6% looked into the pathogenic role of non-coding RNA, followed by DNA methylation (12.1%), histone modification (9.1%), and chromatin changes (4.5%). Nine (13.6%) reports examined the discrepancy of epigenetic signatures between subjects or tissues with and without VC, supporting their applicability as biomarkers. Assisted by bioinformatic analyses blending in each epigenetic component, we discovered prominent interactions between microRNAs, DNA methylation, and histone modification regarding potential influences on VC risk.
