This study aims to reveal the interaction between H3K18la and the lncRNA-miRNA-mRNA regulatory network in hepatocellular carcinoma (HCC). Transcriptome sequencing and ChIP sequencing were performed in HCC and adjacent normal tissues. Cut&amp;Run and qPCR were used to validate the H3K18la enrichment on LINC02732 and CD44 promoter. Dual luciferase reporter assay, qPCR and Western blotting were used to verify the LINC02732-miR-1291-ASF1B axis. Co-Immunoprecipitation was performed to validate ASF1B recruiting p300. CCK8 and mouse subcutaneous tumor formation were performed to demonstrate this axis promoting HCC. H3K18la enrichment on LINC02732 promoter elevates its expression in both HCC samples and cell lines, therefore enhancing ASF1B expression via sponging miR-1291. Moreover, ASF1B, a histone chaperone, promotes H3K18la by recruiting lactyltransferase p300, forming an ASF1B-H3K18la positive feedback loop. The axis upregulates CD44 expression and promotes HCC in vitro and in vivo. These findings demonstrated the influence of H3K18la on the LINC02732-miR-1291-ASF1B axis and the novel role of ASF1B in histone lactylation by recruiting p300, which together promoted HCC proliferation.<\/jats:p>","DOI":"10.3390\/cells15100952","type":"journal-article","created":{"date-parts":[[2026,5,25]],"date-time":"2026-05-25T15:05:08Z","timestamp":1779721508000},"page":"952","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["A Feedback Loop Driven by H3K18la and ASF1B via the LINC02732-miR-1291 Axis Promotes Hepatocellular Carcinoma Proliferation"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4343-4776","authenticated-orcid":false,"given":"Jingya","family":"Yu","sequence":"first","affiliation":[{"name":"Department of Genetics, School of Basic Medical Sciences, Cheeloo College of Medicine, Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lulu","family":"Xin","sequence":"additional","affiliation":[{"name":"Department of Physiology and Pathophysiology, School of Basic Medical Sciences, Cheeloo College of Medicine, Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Cui","sequence":"additional","affiliation":[{"name":"Department of Physiology and Pathophysiology, School of Basic Medical Sciences, Cheeloo College of Medicine, Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-2473-3804","authenticated-orcid":false,"given":"Chunxin","family":"Fan","sequence":"additional","affiliation":[{"name":"Department of Physiology and Pathophysiology, School of Basic Medical Sciences, Cheeloo College of Medicine, Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongheng","family":"Yang","sequence":"additional","affiliation":[{"name":"Department of Physiology and Pathophysiology, School of Basic Medical Sciences, Cheeloo College of Medicine, Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Physiology and Pathophysiology, School of Basic Medical Sciences, Cheeloo College of Medicine, Shandong University, Jinan 250012, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1345","DOI":"10.1016\/S0140-6736(22)01200-4","article-title":"Hepatocellular carcinoma","volume":"400","author":"Vogel","year":"2022","journal-title":"Lancet"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"102406","DOI":"10.1016\/j.jceh.2024.102406","article-title":"Evolving Global Etiology of Hepatocellular Carcinoma (HCC): Insights and Trends for 2024","volume":"15","author":"Koshy","year":"2025","journal-title":"J.
