Abstract
Aging leads to progressive deterioration of the structure and function of arteries, which eventually contributes to the development of vascular aging-related diseases. N6-methyladenosine (m6A) is the most prevalent modification in eukaryotic RNAs. This reversible m6A RNA modification is dynamically regulated by writers, erasers, and readers, playing a critical role in various physiological and pathological conditions by affecting almost all stages of the RNA life cycle. Recent studies have highlighted the involvement of m6A in vascular aging and related diseases, shedding light on its potential clinical significance. In this paper, we comprehensively discuss the current understanding of m6A in vascular aging and its clinical implications. We discuss the molecular insights into m6A and its association with clinical realities, emphasizing its significance in unraveling the mechanisms underlying vascular aging. Furthermore, we explore the possibility of m6A and its regulators as clinical indicators for early diagnosis and prognosis prediction and investigate the therapeutic potential of m6A-associated anti-aging approaches. We also examine the challenges and future directions in this field and highlight the necessity of integrating m6A knowledge into patient-centered care. Finally, we emphasize the need for multidisciplinary collaboration to advance the field of m6A research and its clinical application.

Abstract
Apoptosis, a highly controlled homeostatic mechanism that eliminates single cells without destroying tissue function, occurs during growing development and senescence. N6-methyladenosine (m6A), as the most common internal modification of eukaryotic mRNA, fine-tunes gene expression by regulating many aspects of mRNA metabolism, such as splicing, nucleation, stability, translation, and degradation. Remarkably, recent reports have indicated that aberrant methylation of m6A-related RNA may directly or indirectly influence the expression of apoptosis-related genes, thus regulating the process of cell apoptosis. In this review, we summarized the relationship between m6A modification and cell apoptosis, especially its role in the nervous system, and analyzed the limitations of the current research.

Abstract
Senescence is the underlying mechanism of organism aging and is robustly regulated at the post-transcriptional level. This regulation involves the chemical modifications, of which the RNA methylation is the most common. Recently, a rapidly growing number of studies have demonstrated that methylation is relevant to aging and aging-associated diseases. Owing to the rapid development of detection methods, the understanding on RNA methylation has gone deeper. In this review, we summarize the current understanding on the influence of RNA modification on cellular senescence, with a focus on mRNA methylation in aging-related diseases, and discuss the emerging potential of RNA modification in diagnosis and therapy.

Downregulation of ALKBH5 rejuvenates aged human mesenchymal stem cells and enhances their therapeutic efficacy in myocardial infarction. FASEB J 2023; 37:e23294. [PMID: 37966425 DOI: 10.1096/fj.202301292r] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 10/01/2023] [Accepted: 10/25/2023] [Indexed: 11/16/2023]
Abstract
Despite promising results in myocardial infarction (MI), mesenchymal stem cell (MSC)-based therapy is limited by cell senescence. N6-methyladenosine (m6A) messenger RNA methylation has been reported to be closely associated with cell senescence. Nonetheless, its role in the regulation of MSC senescence remains unclear. We examined the role of ALKB homolog 5 (ALKBH5) in regulating MSC senescence and determined whether ALKBH5 downregulation could rejuvenate aged MSCs (AMSCs) to improve their therapeutic efficacy for MI. RNA methylation was determined by m6A dot blotting assay. MSC senescence was evaluated by senescence-associated β-galactosidase (SA-β-gal) staining. A mouse model of acute MI was established by ligation of the left anterior decedent coronary artery (LAD). Compared with young MSCs (YMSCs), m6A level was significantly reduced but ALKBH5 was greatly increased in AMSCs. Overexpression of ALKBH5 reduced m6A modification and accelerated YMSC senescence. Conversely, ALKBH5 knockdown increased m6A modifications and alleviated AMSC senescence. Mechanistically, ALKBH5 regulated the m6A modification and stability of CDKN1C mRNA, which further upregulated CDKN1C expression, leading to MSC senescence. CDKN1C overexpression ameliorated the inhibition of cellular senescence of ALKBH5 siRNA-treated AMSCs. More importantly, compared with AMSCs, shALKBH5-AMSCs transplantation provided a superior cardioprotective effect against MI in mice by improving MSC survival and angiogenesis. We determined that ALKBH5 accelerated MSC senescence through m6A modification-dependent stabilization of the CDKN1C transcript, providing a potential target for MSC rejuvenation. ALKBH5 knockdown rejuvenated AMSCs and enhanced cardiac function when transplanted into the mouse heart following infarction.

Abstract
Similar to epigenetic DNA modification, RNA can be methylated and altered for stability and processing. RNA modifications, i.e., epitranscriptomes involve three functions, that is, writing, erasing, and reading of marks. Methods for measurement and position detection are useful for the assessment of cellular function and human disease biomarkers. Since the first detection of pyrimidine 5-methylcytosine hundred years ago, numerous techniques have been developed to study the modifications of nucleotides, including RNAs. Recent studies focused on high throughput and direct measurements to investigate the precise function of epitranscriptomes, including the characterization of SARS-CoV-2. The current work presents an overview of the development of detection techniques for epitranscriptomic marks and updates recent progress on the related field.
