Myopia, also known as nearsightedness, refers to a refractive error of the eye that causes parallel rays of light to focus in front of the retina, affecting distance vision. High myopia significantly increases the risk of pathological myopia, leading to severe complications and an increased likelihood of myopia-related eye diseases. In recent decades, the incidence of myopia has continued to rise, posing significant social and human health issues. The complex interplay between genetic and environmental variables affects the development of myopia. Gene control depends to a large extent on epigenetic changes, which are reversible, inheritable, and sensitive to ecological shifts. Therefore, the pathophysiology and development of myopia are tightly linked to gene regulation mediated by epigenetic changes. To explore epigenetic modifications related to myopia, a PubMed search was conducted using keywords such as epigenetic modification, epigenetics, DNA methylation, RNA methylation, non-coding RNA, long non-coding RNA, short interfering RNA, microRNA, ribosomal RNA, circular RNA, transfer RNA, histone modification, histone methylation, and histone acetylation. This review presents the current understanding of these epigenetic modifications in myopia to provide new insights for advancing myopia research.

Oncometabolites are aberrant metabolic byproducts that arise from mutations in enzymes of the tricarboxylic acid (TCA) cycle or related metabolic pathways and play central roles in tumor progression and immune evasion. Among these, 2-hydroxyglutarate (2-HG), succinate, and fumarate are the most well-characterized, acting as competitive inhibitors of α-ketoglutarate-dependent dioxygenases to alter DNA and histone methylation, cellular differentiation, and hypoxia signaling. More recently, itaconate, an immunometabolite predominantly produced by activated macrophages, has been recognized for its dual roles in modulating inflammation and tumor immunity.

Head and neck squamous cell carcinoma (HNSCC) is among the most prevalent human malignancies globally, with approximately 887,000 new cases diagnosed each year. Currently, the standard treatment for HNSCC involves surgery, followed by radiotherapy, chemotherapy and immunotherapy. However, despite these available treatments, the survival rate of patients with HNSCC remains low.

Triple-negative breast cancer (TNBC) presents a formidable therapeutic challenge due to its aggressive behavior, molecular heterogeneity, and lack of actionable targets. This study identifies activation-induced cytidine deaminase (AID) as a pivotal epigenetic driver reprogramming the tumor microenvironment (TME) via non-canonical regulation of NOTCH signaling. Mechanistically, AID recruits histone acetyltransferase 1 (HAT1) to form a chromatin-remodeling complex that binds the JAG1 promoter region (-1.

Lactylation is a novel post-translational modification (PTM) mediated by lactate, which dynamically regulates protein functions and gene expression by covalently attaching lactate groups to lysine residues. Recent studies have shown that abnormal lactate metabolism not only contributes to the pathogenesis of epilepsy through microenvironment acidification but also influences neuroinflammation, energy metabolism imbalance, neurotransmitter dysregulation, synaptic plasticity, and epigenetic regulation via lactylation. This positions lactylation as a critical metabolic-epigenetic intersection in the pathological mechanisms of epilepsy.

Ethnopharmacological Relevance: Huopu Xialing Decoction (HXD) is a traditional Chinese medicine (TCM) formula widely used in the clinical treatment of respiratory viral infections. Despite its established application, the pharmacological mechanisms underlying its therapeutic effects against influenza remain to be fully elucidated.
Aim Of The Study: This study aimed to investigate the protective effects of HXD against influenza A virus-induced lung inflammation and to explore the role of gut microbiota and epigenetic regulation in mediating these effects.
