For example, KLF13 knockdown led to decreased apoptosis and increased proliferation of hepatocellular carcinoma (HCC) cells in vitro [34]; however, in another study, KLF13 was found to be over-expressed in HCC tissue, while KLF13 knockdown suppressed HCC cell proliferation, migration, and invasion, and drove HCC cell apoptosis in vitro [35]. Here, KLF13 is linked to hepatocellular carcinoma.
