Project description:Histone deacetylases (HDACs) are essential transcriptional regulators that mediate gene expression through the complexes they are involved in. Thus, deciphering the HDAC-associated proteins is key to elucidating the underlying mechanisms. Here we present an efficient tool, termed heterobifunctional molecule-enabled proximity labeling strategy (BimPL), to investigate endogenous HDAC neighboring proteins in living cells. Leveraging BimPL and quantitative proteomics, we enable the robust capture of several known HDAC complexes as well as numerous putative HDAC interactors such as glycolytic enzyme enolase-1 (ENO1). Through biochemical studies and CUT&Tag analysis, we uncovered that nuclear ENO1 interacts with HDAC1, which in turn blunts the activity of HDAC1 via locally generated phosphoenolpyruvate (PEP), thereby mediating histone lysine lactylation (Kla) and gene transcription. Our study offers a versatile tool for systematic exploring endogenous protein complexes, as well as provides insight into the unidentified function of ENO1 in the regulation of histone Kla and liver tumor progression.

Project description:Protein lactylation is a process that is fueled by lactate, generated by the enzyme lactate dehydrogenase (Ldh) from pyruvate. Despite prior research, the precise role of protein lactylation in controlling the identity of mouse embryonic stem cells (ESCs) is still not fully understood. We observed that inhibiting or eliminating Ldha causes a reduction in global protein lactylation in ESCs, and RNA-seq analysis suggests that Ldha inhibition induces a 2-cell-like cell (2CLC) signature in ESCs. To probe the underlying mechanisms, we performed quantitative lactylation proteomics analysis, we discovered that Hdac1, a gene with significant regulatory roles during the 2-cell stage (2C), undergoes lactylation modification. Additionally, we observed that treatment with an Ldh (lactate dehydrogenase) inhibitor can decrease the lactylation levels of Hdac1. Mechanistically, we discovered that Ldha positively regulates the lactylation of Hdac1, promoting its direct binding to zygotic genome activation (ZGA) gene promoters and has stronger deacetylase activity. This leads to the removal of acetyl groups from H3K27 on these loci, effectively suppressing the expression of 2C genes. Our study presents novel evidence supporting protein lactylation's potential as a means of inhibiting the generation of 2CLCs and modulating acetylation activity.

Project description:Enolase 1 (ENO1) is a glycolytic enzyme that plays essential roles in various pathological activities including cancer development. However, the mechanisms underlying ENO1-contributed tumorigenesis are not well explained. Here, we uncover that ENO1, as an RNA-binding protein, binds to the cytosine-uracil-guanine-rich elements of YAP1 messenger RNA to promote its translation. ENO1 and YAP1 positively regulate alternative arachidonic acid (AA) metabolism by inverse regulation of PLCB1 and HPGD (15-hydroxyprostaglandin dehydrogenase). The YAP1/PLCB1/HPGD axis-mediated activation of AA metabolism and subsequent accumulation of prostaglandin E2 (PGE2) are responsible for ENO1-mediated cancer progression, which can be retarded by aspirin. Finally, aberrant activation of ENO1/YAP1/PLCB1 and decreased HPGD expression in clinical hepatocellular carcinoma samples indicate a potential correlation between ENO1-regulated AA metabolism and cancer development. These findings underline a new function of ENO1 in regulating AA metabolism and tumorigenesis, suggesting a therapeutic potential for aspirin in patients with liver cancer with aberrant expression of ENO1 or YAP1.

Project description:Embryonic cells engage in diverse types of metabolism to execute specialized tasks in the developing embryo. Recent studies have demonstrated that metabolic reprogramming can also drive changes in cell identity and behavior by affecting the expression of developmental genes. However, the connection between cellular metabolism and differential gene expression is still not well understood. Here we report found that histone lactylation, an epigenetic mark derived from glycolysis-derived lactate, couples the metabolic state of embryonic cells with gene expression and the activation of gene regulatory networks. Embryonic tissues with high glycolytic flux, like the neural crest and the pre-somitic mesoderm, display high levels of lactylation. The lactylation mark is dynamically deposited in the loci of neural crest genes as these cells transition to a state of enhanced glycolysis. This process promotes accessibility of active enhancers and is necessary for proper deployment of the neural crest gene regulatory network. When we reduced the deposition of the mark by targeting LDHA and LDHB, lactylated genes were downregulated, and neural crest migration was impeded. Lactylation of neural crest enhancers is controlled by transcription factors SOX9 and YAP/TEAD, which are necessary and sufficient for the deposition of the mark. These findings define an epigenetic mechanism that integrates cellular metabolism with the gene regulatory networks that orchestrate embryonic development.
