[Construction of eukaryotic expression vectors for different domains of the extracellular region of RAGE and their expression in prostate cancer cells].

OBJECTIVE: To construct eukaryotic expression vectors for different domains (V and VC1) of the extracellular region of the receptor of advanced glycation end products (RAGE) and investigate the roles of these domains in prostate cancer. METHODS: The coding sequence of V and VC1 domains was amplified from the plasmid pcDNA3-HA-RAGE by PCR and cloned into the pcDNA3-HA vector following routine procedures. After identification by PCR and sequencing, the vectors including V and VC1 domains were transfected into PC-3 cells. Western blotting and immunofluorescence were used to detect the expression and distribution of the expressed products in transfected PC-3 cells. RESULTS: The expression vectors containing V and VC1 domains of RAGE were successfully constructed as confirmed by PCR and DNA sequence analysis. The V and VC1 domains of RAGE were highly expressed and showed a cytoplasmic distribution in transfected PC-3 cells. CONCLUSION: The constructed eukaryotic expression vectors for V and VC1 domains of RAGE can be efficiently expressed in prostate cancer cells.
