Objective To observe the proliferation and migration of human hapetocelluar carcinoma cell line HepG2 after the introduction of exogenous cysteine rich 61 (Cyr61). Methods Adenviral vector
AdEasy with a report gene
red fluorescence protein (RFP) was used to construct recombinant vector Ad-Cyr61. The vectors Ad-Cyr61 and Ad-RFP (control) were transformed into HepG2 cells to observe the protein and mRNA expression of Cyr61 by immunohistochemistry and RT-PCR. MTT
cell counting
plate colony formation and cell wound healing assay were performed to determine the Cyr61’s effect on the proliferation and migration of HepG2. Results Ad-Cyr61 transfected HepG2 cells expressed exogenous Cyr61
formed more clones
proliferated more cells and exhibited a greater ability to migrate in cell wound healing than the control cells. Conclusion Exogenous Cyr61 stimulates the proliferation and migration of HCC cells
suggesting that Cyr61 may play a role in tumorigenesis and metastasis.
