miRNA enrichment analysis showed that HCC cells carried miRNAs, with a concentration of miRNAs acting on active pathways such as PI3K/AKT, PTEN, and cellular senescence (Figure 5D), which suggests that BaP regulates the tumor microenvironment and influences the cellular state through exosomes, thus providing the basis for tumor cell metastasis. This evidence concerns the gene AKT1 and hepatocellular carcinoma.
