Article Abstract
In this paper, we present and analyze a model for metabolism and lactylation in a single microglia. The model includes positive feedback from lactylation in the glycolytic pathway, and links metabolism and inflammation. Specific pathways include the transition of glucose to pyruvate to lactate in a microglia, as well as the gradient transport of glucose and lactate into and out of the cell. Additionally, the upregulation of certain pathways by either epigenetic modification or the inflammatory response are included. Bifurcation and sensitivity analyses demonstrate the importance of key parameters and pathways in the model, specifically the role of lactylation. Our model is validated by qualitatively reproducing recent in vitro experiments in which exogenous glucose and lactate are modified.

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.

Introduction: Lactate has emerged as a multifunctional signaling molecule regulating various physiological and pathological processes. Furthermore, lactylation, a newly identified posttranslational modification triggered by lactate accumulation, plays significant roles in human health and diseases. This study aims to investigate the roles of lactate/lactylation in respiratory diseases.

Post-translational modifications (PTMs) are chemical modifications that occur on specific amino acid residues after protein biosynthesis, which can affect protein function by altering protein structure, localization and activity, thus expanding protein diversity. Extensive research has demonstrated that PTMs can regulate various metabolic processes, such as glucose and lipid metabolism, as well as immune modulation in tumor cells, thereby promoting tumor initiation, progression, and metastasis. In this article, we systematically review a class of emerging PTMs whose roles in tumor metabolism and immune regulation have gradually been recognized in recent years, including six types: lactylation, palmitoylation, SUMOylation, succinylation, crotonylation, and myristoylation.

Background: Emerging evidence indicates that lactase-mediated histone lactylation can activate osteogenic gene expression and promote bone formation. However, the role of lactylation-related genes (LRGs) in osteoporosis (OP) remains unclear. This study aims to clarify the key roles of LRGs and the molecular mechanisms of related biomarkers in OP.

Thyroid carcinoma is among the most common endocrine system malignancies. Lactate metabolism and lactylation modification roles in carcinogenesis and development have garnered more interest in recent years. The expression and function of lactate transporters (MCTs) and significant metabolic enzymes are included in our summary of the characterisation of lactate metabolism in thyroid cancer.
