ABSTRACT
<p><b>OBJECTIVE</b>To investigate effect of interference therapy induced by epidermal growth factor receptor (EGFR)-antisense cDNA in signal transduction of Hep-2 laryngeal squamous cell carcinoma in vitro.</p><p><b>METHODS</b>AdEasy Vector System was used to construct the recombinant adenovirus vector sense/antisense-pAdEasy-EGFR. The recombinant adenovirus vector introduced EGFR-sense/antisense cDNA fragment into HEK293 cell. The purified recombinant adenovirus sense/antisense-pAdEasy-EGFR transfected Hep-2 cells in vitro. The inhibition of EGFR protein expression and proliferation of Hep-2 cells, the changes of cell cycle and DNA content in Hep-2 cells were examined by MTT, Western blot analysis, flow cytometry essay, and immunocytochemistry respectively.</p><p><b>RESULTS</b>The higher titre sense and antisense mRNA expression recombinant adenovirus containing 1,032 bp EGFR-cDNA was constructed and prepared successfully. When antisense-pAdEasy-EGFR was transferred into Hep-2 cells the inhibition of cell proliferation and EGFR protein expression in Hep-2 cells were investigated effectively.</p><p><b>CONCLUSION</b>The antisense-pAdEasy-EGFR effectively interfere the Hep-2 signal transduction pathway and induce apoptosis which results in inhibiting proliferation of laryngeal squamous cell carcinoma.</p>
