Abstract:
Objective To study the expression of WWOX and C-JUN in keloid and to approach their role and mechanism in the pathogenesis of keloid.Methods Immunohistochemical SP methods were used with computer pathological image analysis.Western blot and reverse transcription polymerase chain reaction (RT-RCR) were performed to detect the expression of WWOX and C-JUN in keloid and normal skin with statistical analysis.Results In keloid,the expression of WWOX protein was located in the cytoplasm of fibroblasts,and the expression of WWOX protein and its mRNA decreased,with significantly statistical difference (P＜0.05) compared to normal skin in the control group; the expression of C-JUN protein was located in the cell nucleus and cytoplasm of fibroblasts,with increased expression of C-JUN protein and its mRNA,with significantly statistical difference (P＜0.05) in comparison to normal skin in the control group.The expression of both was negative correlation (r=-0.626,P＜0.01).Conclusions Both WWOX with low expression and C-JUN with high expression are keloid-related genes,having significantly negative correlation between them,which may be one of the mechanisms for the keloid formation.It indicates that the WWOX protein may be an inhibitory factor to the expression of C-JUN protein,and the genes may play a major role in the pathogenesis of keloiod through fibroblasts.
