ASH2L and hepatocellular carcinoma: To further investigate how lactylation enhanced ASH2L‐mediated angiogenesis in HCC, we performed chromatin immunoprecipitation sequencing (ChIP‐seq) analysis of FLAG‐tagged WT and mutant ASH2L proteins in Huh‐7‐ASH2L‐K312R and Huh‐7‐WT cells to explore alterations in ASH2L binding sites across the genome (Figure4A).
