The genome-wide targeting of H3K18la in H1299 cells

L-lactate was reported as a precursor that can label and stimulate histone lysine-N-L-lactylation (Kla), which represents a new epigenetic mark affecting gene expression directly via histone PTMs under conditions of high glycolysis, such as the Warburg effect. To investigate the genome-wide targeting of H3K18la, we performed ChIP-seq in H1299 cells using anti-H3K18la antibody. 50.6% of the H3K18la binding sites displayed enrichment close to -1kb promoter of genes. More importantly, our ChIP-seq data showed that H3K18la is enriched in many genes that related with replication processes, highlighted the importance of histone Kla involved in DNA replication. Overall design: Human NSCLC cell line H1299, including anti-H3K18la and IgG group.
