[Effect of lentivirus-mediated nestin gene silencing on metastatic potential of human melanoma cell line UACC903 in vitro].

Abstract

OBJECTIVE:

To study the effect of lentivirus-mediated RNA interference (RNAi) of nestin on the metastatic potential of human melanoma cell line UACC903.

METHODS:

A lentiviral vector for RNAi targeting the coding region of human nestin mRNA (nestin-RNAi-LV) and another control vector containing a nonsense sequence were constructed. The vectors were transfected into UACC903 cells, and nestin expression in the cells was detected by RT-PCR, immunofluorence assay and Western blotting. The invasive ability and migration of the transfected UACC903 cells was evaluated using Transwell and scrape assay, respectively. Fluorescence assay was used to examine the expressions of E-cadherin, N-cadherin and β-catenin in the cells.

RESULTS:

The lentiviral vector nestin-RNAi-LV was constructed successfully. Compared with the control vector, nestin-RNAi-LV resulted in obviously reduced expression of nestin mRNA and protein, lowered migration ability of UACC903 cells, and reduced cell adhesion and invasiveness (P<0.05).

CONCLUSION:

Lentivirus-mediated nestin RNAi can specifically inhibit nestin expression to cause decreased cell migration and invasiveness of human melanoma cell line UACC903.
