Objective:To investigate the effects of EMP1 on the proliferation and invasion of oral squamous cancer cells(OSCC)in vitro.Methods:pEGFP-N1-EMP1 expression vectors were constructed and transfected stably into Tb3.1cell.Tb3.1-pEGFP-N1-EMP1 cell,wild type Tb3.1cell and Tb3.1-pEGFP-N1 cell were tested using MTT to assay cell proliferation.Cell cycle and invasion were analyzed by flow cytometry and invasion assay,respectively.One-way ANOVA was adopted to compare among groups.Results:Compared with wild type Tb3....
