Moreover, in the coffee consuming group, the traces of acrylamide and furan exert antagonistic effects against the examined chemopreventive agents; namely, acrylamide (≤100 μmol/L) in vitro, which significantly increases the proliferation of human HCC HepG2 cells and induces the EGFR/PI3K/AKT/cyclin D1 pathway, leading to decreased PTEN levels [98]. Here, AKT1 is linked to hepatocellular carcinoma.
