Effect of stable transfection with PHD3 on growth and proliferation of HepG2 cells in vitro and in vivo.

ABSTRACT:

Objective

To establish a human hepatoma HepG2 cell line with stable expression of Prolyl hydroxylase domain 3 (PHD3) gene and study its effect of growth and proliferation in nude mice xenograft tumor.

Methods

Eukaryotic expression vectors of pcDNA 3.1-PHD3 was constructed. HepG2 cells were transfected with recombinant plasmid pcDNA 3.1-PHD3 and empty vector plasmid pcDNA 3.1 by lipofectamine 2000 as transfected group, control group respectively, while the HepG2 cell without any operation was considered as parental group. Steady expression cells were gotten by G418 selecting. RT-PCR and agarose gel electrophoresis were used to confirm the expression of PHD3 in HepG2 cells and transfection successfully. The growth of these cells in vivo were also observed by injecting three gr
