Research Abstract

We believed that the changes in the genomes derived from HCC were deeply involved in the growth or malignant transformation of HCC cells. We have already reported that CREB3L4(cyclic AMP responsive element binding protein 3-like 4) located in 1q21p, which belonged to the CREB/ATF family, was amplified and was expressed in high levels in HCC samples. In the process of further research, we found that the nuclear expression of P300, a transcriptional co-factor, was associated with the vascular invasion and intrahepatic metastasis of human HCCs. Furthermore, we identified that high expression of P300 in HCC was associated with epithelial mesenchymal transition-like phenotypic change and cyclin D1/beta-catenin dependent growth of HCC cells which might explain the poor prognosis of the patients.
