Notch1 differentially regulates oncogenesis by wildtype p53 overexpression and p53 mutation in grade III hepatocellular carcinoma
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.
