Seung‐Oe Lim, Young Min Park, Hyeon Seop Kim, Xiaoyuan Quan, Jeong Eun Yoo, Young Nyun Park, Gi Hong Choi, Guhung Jung – 27 January 2011 – The tumor suppressor p53 is a key prognostic factor in hepatocellular carcinoma (HCC), yet only 35% of grade III tumors exhibit mutation of p53. Several other pathways have been implicated in HCC and, among these, the role of the Notch1/Snail pathway remains unclear. Therefore, we investigated the expression of p53, Notch1, and Snail proteins in HCC with regard to both clinical grade and p53 mutational status.
