ABSTRACT: To investigate the effect of RNA interference mediated angiopoietin-2 (ANG-2) gene silencing on human endometrial carcinoma cell line Ishikawa.
Short hairpin RNA (shRNA) targeting ANG-2 gene was designed and transfected into Ishikawa cells with Lipofectamine 2000. The mRNA and protein expression level of ANG-2, proliferation, morphological changes, apoptosis, cell cycle and invasive ability of the cells after transfection were analyzed.
The shRNA targeting the human ANG-2 gene effectively decreased the expression of ANG-2 on both mRNA and protein level, the proliferation inhibition rate of the Ishikawa cells was 63.11%, cell apoptosis was induced, and the cell cycle was arrested in G1 phase. The apoptotic rate of the Ishikawa cells in the transfected group was significantly higher, and the invasive ability was decreased markedly, than that of control groups.
The shRNA targeting human ANG-2 gene could reduce ANG-2 expression, inhibit cellular growth and invasion in Ishikawa cells in vitro.
