ABSTRACT
Objective To explore the expression and significance of Dickkopf-1 (Dkk-1) and cell lymphoma/leukemia-2 (Bcl-2) protein in sinonasal squamoucell carcinoma(SNSCC) .MethodThe immunohistochemical SP method and Western blomethod were adopted to determine the expression of Dkk-1 and Bcl-2 in 30 specimenof SNSC(SNSCgroup) ,38 specimenof sinonasal inverted papillomas(SNIP group) and 20 specimenof middle turbinate mucosa(control group) .ResultThe expression of DKK-1 protein in the SNSCgroup wasignificantly down-regulated compared with the SNIP group and the control group ,while the expression of Bcl-2 protein in the SNSCgroup wasignificantly up-regulated compared with the SNIP group and the control group;in the SNSCgroup ,the positive rateof DKK-1 protein and Bcl-2 protein in the high and middle differentiation group and the low differentiation group were 100 .00% ,68 .75% ,33 .33% and 50 .00% ,62 .50% ,100 .00% respectively ,the differencewere statistically significan(P<0 .05) .Conclusion Dkk-1 protein may play an importanpromoting role in the developmenand pro-gression procesof SNSC,the expression of Dkk-1 protein hanegative correlation with the expression of Bcl-2 protein in SNSC,which may become new targespoof SNSCgene therapy .
