| Outline of Final Research Achievements |
We previously reported that adenomatous polyposis coli-binding protein EB1 (EB1) is overexpressed in HCC tissues by proteomics. In present study, ①EB1 expression significantly correlated with the degree of histological differentiation, AFP, vascular invasion status in HCC patients. Moreover, overall survival and recurrence rate was significantly poor in EB1-high expressed HCC patients. ②EB1 promoted cell proliferation, migration, invasion, tumor growth in HCC cell lines. ③Microarray analysis revealed that EB1 might regulate the expression level of Dlk-1. As a conclusion, EB1 may become a new biomarker of HCC and a potential molecular target of HCC therapy.
