ABSTRACT
<p><b>OBJECTIVE</b>To explore the effects of antisense epidermal growth factor receptor (EGF-R) oligodeoxynucleotides on ultraviolet-induced c-jun activity of keratinocytes after EGF-R oligodeoxynucleotides transfect to HaCaT in vitro.</p><p><b>METHODS</b>c-jun DNA binding activity after ultraviolet-B (UVB) irradiation and EGF-R oligodeoxynucleotides transfection were determined with a highly sensitive and specific colorimetric method. After EGF-R oligodeoxynucleotides transfection, the mRNA level of EGF-R was detected by reverse transcription polymerase chain reaction method.</p><p><b>RESULTS</b>Compared with control groups, c-jun activity increased significantly in UVB (10, 20, 30 mJ/cm2) irradiation groups (P < 0.05). EGF-R mRNA and c-jun activities induced by UVB were inhibited after the keratinocytes were transfected with EGF-R antisense oligodeoxynucleotides at 2, 4 and 8 microg/ml concentrations (P < 0.01).</p><p><b>CONCLUSION</b>The ultraviolet-induced c-jun activity of keratinocytes can be mediated by EGF-R and inhibited by EGF-R antisense oligodeoxynucleotides, which is transfected to keratinocytes and mediated by lipofectamine.</p>
