Although Versican is an extracellular matrix protein, Versican is also expressed in the liver cytoplasm and functions as an invasion enhancer.20 Versican transcription is regulated not only by TCF, but also by p5326 and AP-1.27 However, p53 and AP-1 did not affect Versican transcription in HCC cells (data not shown), indicating that the regulation of Versican transcription is cell type-specific. Here, VCAN is linked to hepatocellular carcinoma.
