• • What is Histone Malonylation and How Does It Work?

  In life science research, histone modifications have long been central to epigenetic studies. Histones, as the primary structural proteins of chromatin, undergo chemical modifications that not only regulate chromatin compaction but also influence gene expression, cell differentiation, and disease progression. In recent years, a novel modification termed histone propionylation (Hpr) has emerged as a prominent focus of research. Basic Concept of Histone Propionylation Histone propionylation is an acyla......

• • How to Identify Disease Biomarkers Using Exosome Proteomics?

  In precision medicine and early disease diagnosis research, exosome proteomics has emerged as a crucial tool for discovering reliable biomarkers. Exosomes are extracellular vesicles with diameters of 30-150 nm that carry proteins, nucleic acids, lipids, and other molecules, reflecting the physiological and pathological state of their originating cells. Unique Advantages of Exosomes in Disease Research Exosomes possess several key characteristics that make them ideal candidates for biomarker studies: ......

• • What is Histone Propionylation and What Are Its Biological Functions?

  Within the complex epigenetic regulatory network, post-translational histone modifications continue to be identified, greatly expanding our understanding of gene expression regulation. Following classical modifications such as acetylation and methylation, histone propionylation, a metabolite-derived modification, has recently attracted increasing attention. This modification not only links cellular metabolic states to chromatin structural dynamics but also plays distinct roles in transcriptional regul......

• • What Is the Complete Workflow of Histone Propionylation Analysis?

  With the increasing depth of research in epigenetic regulation, histone post-translational modifications (PTMs) have emerged as a critical approach for elucidating mechanisms of gene expression regulation. In recent years, beyond classical modifications such as acetylation and methylation, histone propionylation (Kpr) has gained considerable attention as an emerging modification due to its close association with cellular metabolic states. As a key metabolic intermediate, fluctuations in propionyl-CoA ......

• • How Is Histone Butyrylation Linked to Short-Chain Fatty Acid Metabolism?

  With the rapid advancement of epigenetics, histone post-translational modifications (PTMs) have emerged as a central avenue for elucidating mechanisms of gene expression regulation. In recent years, histone butyrylation (Kbu), an emerging type of acylation modification, has attracted increasing attention in the life sciences. Concurrently, short-chain fatty acids (SCFAs), key metabolites produced by the gut microbiota, are increasingly recognized for their roles in host metabolism and epigenetic regul......

• • How Does Butyryl-CoA Drive Histone Kbu Formation?

  In the field of epigenetic regulation, the repertoire of histone post-translational modifications is continually expanding. Lysine butyrylation (Kbu), a recently recognized acylation modification, has gradually emerged as a key regulator of chromatin architecture and gene expression. Compared with classical acetylation, Kbu possesses a longer carbon chain and greater hydrophobicity, enabling it to exert distinct effects on protein conformation and molecular interactions. Meanwhile, butyryl coenzyme A ......

• • How to Perform Histone Acetylation Analysis?

  Histone acetylation, as one of the most well-established epigenetic modifications, plays a central role in regulating chromatin structure and activating gene transcription. Acetyl groups neutralize the positive charge of lysine residues, thereby weakening the interaction between DNA and histones and promoting the transition of chromatin from a compact to a more open state. This dynamic regulatory process is widely involved in biological processes such as cell differentiation, tumorigenesis, and immune......
