The results show that MICB expression in pancreatic cancer cell lines PANC-1 and BxPC-3 cells was significantly higher than that in lung cancer cell line A549, hepatocellular carcinoma cell line HepG2, and pancreatic cancer cell line AsPC-1, whereas lung cancer cell line A549 had the lowest MICB protein expression. Here, MICB is linked to hepatocellular carcinoma.
