The state of chromatin is governed by an interplay between various histone modifications, variants, nucleosome remodeling complexes, and other chromatin modifiers that work in sync to prime the chromatin for specific biological outcomes. In this chapter, we explore neural crest cells (NCCs), a critical progenitor population that retains the extensive developmental potential of their blastula origins. The formation and differentiation of NCCs into diverse cell types are influenced by the regulation of their acetylation state through various epigenetic factors. This chapter delves into the intricate interplay between histone acetylases (HATs) and deacetylases (HDACs), highlighting how these enzymes modify chromatin to create a permissive environment for the induction of NCCs and steer their fate toward the melanocytic lineage. The shift in acetylation profiles during the transition from melanocytes to melanoma suggests that the transcriptional machinery may override normal regulatory mechanisms, promoting a neural crest-like state in melanoma development. Epigenetic regulation, particularly through histone acetylation, plays a pivotal role in neural crest cell development and melanoma initiation offering potential therapeutic targets.","PeriodicalId":39320,"journal":{"name":"Results and Problems in Cell Differentiation","volume":"75 ","pages":"189-209"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144545322","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Neural precursor cells (NPCs) and parenchymal oligodendrocyte precursor cells (OPCs) play a key role in myelin plasticity in the central nervous system (CNS), being specialized in reconstituting the myelin sheath upon damage. Reversible acetylation, regulated by histone acetyltransferases (HATs) and histone deacetylases (HDACs) activity, controls these stem cells' differentiation in myelinating oligodendrocytes (mOLs) during their proliferation and remyelination processes. By modulating cytosolic protein activity and precisely orchestrating the spatial and timely regulated activity of the transcription factors participating in the NPC and OPC differentiation process, these enzymes play a vital role in preserving the adult brain's cognitive capacity during ageing. This review highlights the role of reversible acetylation in the regulation of stem cell differentiation during remyelination, as disruptions in this process contribute to severe neurodegenerative impairments and accelerated ageing.","PeriodicalId":39320,"journal":{"name":"Results and Problems in Cell Differentiation","volume":"75 ","pages":"213-246"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144545324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This post-translational modification (PTM) enhances MT flexibility and resilience, enabling cells to withstand mechanical challenges such as changes in extracellular matrix stiffness and applied forces. Through its impact on MT physical properties, acetylation minimizes cytoskeletal breakage, reducing the need for constant remodeling and supporting cellular integrity under mechanical stress. Furthermore, tubulin acetylation regulates intracellular trafficking by modulating interactions with molecular motors, allowing for efficient cargo transport and precise spatial organization without disrupting the MT network. In the context of oxidative stress, tubulin acetylation responds to redox imbalances by stabilizing MTs and influencing cellular pathways that regulate reactive oxygen species (ROS). This modification is linked to enhanced antioxidant responses, autophagy regulation, and mitochondrial dynamics, highlighting its role in maintaining cellular homeostasis under oxidative conditions. The dual function of tubulin acetylation, responding to and integrating signals from mechanical and oxidative stress, acts as a bridging mechanism between physical and chemical signaling pathways. Consequently, it has the potential to be a therapeutic target in diseases characterized by dysregulated stress responses, including neurodegenerative disorders, cancer, and cardiovascular conditions. Despite significant progress has been made, unanswered questions persist, particularly regarding the molecular mechanisms by which acetylated MTs encode spatial and functional information and their interplay with other tubulin PTMs.","PeriodicalId":39320,"journal":{"name":"Results and Problems in Cell Differentiation","volume":"75 ","pages":"141-162"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144545330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, viruses are obligate intracellular parasites hence require the machinery of other organisms to multiply. Consequently, most viral infections result into a viral disease. Broadly, viruses cause two types of infection-acute and persistent (latent and chronic), in humans and other mammals that could lead to various lethal and non-lethal viral diseases. Acetylation is now known to be a ubiquitous protein (and nucleic acid) modification and is critical for cellular metabolism. An imbalance in acetylation has been associated with various cancers and diseases in humans. Likewise, the association of acetylation with viral infection and disease was observed soon after its discovery in twentieth century. Now, the literature accumulated in this space shows that acetylation promotes the infection of many viruses causing both acute and persistent infections. Furthermore, reduction in the acetylation level reduces viral clearance from the host and promotes viral persistency. The latter can be interrupted by increasing the acetylation level by using deacetylase inhibitors. Indeed, this approach has become a therapeutic tool to treat and clear the persistent viral infections as well as boost the oncolytic virus-mediated cancer therapy.","PeriodicalId":39320,"journal":{"name":"Results and Problems in Cell Differentiation","volume":"75 ","pages":"329-361"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144545319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MTs are polymers of α/β-tubulin heterodimers, playing a myriad of distinct cellular functions and are the main components of complex structures like the mitotic spindle, cilia, and centrioles. Post-translational modifications (PTMs) regulate the function and increase the complexity of the α/β-tubulin heterodimer pools. One of the PTMs that has been extensively studied is the acetylation of lysine 40 (K40) on α-tubulin, which specifically occurs inside the MT lumen.Acetylation plays a crucial role in controlling the stability and function of MTs, in response to signals from within and outside the cell. It impacts the cytoplasm's 3D arrangement and important cellular activities like intracellular transport, cell division, polarity, and migration. Recent research has also emphasized the significance of this PTM in regulating the mechanical properties of MTs and cellular sensing. The levels and activity of MT acetyltransferases and deacetylases are tightly regulated through various transcriptional, post-transcriptional, and post-translational mechanisms, including miRNAs, phosphorylation, protein-protein interactions, and regulated localization between the nucleus and cytoplasm. These regulatory processes involve components of diverse signaling pathways, and their deregulation has been implicated in numerous diseases, including neurological disorders, cancer, and cardiac conditions.","PeriodicalId":39320,"journal":{"name":"Results and Problems in Cell Differentiation","volume":"75 ","pages":"91-140"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144545331","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
