ATAC-Seq data analysis revealed that PABPC1 promoter was more accessible in CD24+CD133+ liver CSCs than in non-CD24+CD133+ HCC cells (Figure 5E), suggesting that SETD1A not only interacted with PABPC1 but also regulated the transcriptional activity of PABPC1. Here, PROM1 is linked to hepatocellular carcinoma.
