Popis: 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.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.Compared with control groups, c-jun activity increased significantly in UVB (10, 20, 30 mJ/cm2) irradiation groups (P0.05). 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 (P0.01).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.
