Abstract:
Objective To investigate the effect and significance of salidroside on Eag1 expression in mouse cervical cancer xenograft.Methods The mouse subcutaneous xenograft model of cervical cancer U14 cells was established.Forty female Kunming mice were divided into 4 groups according to the random principle,the xenograft group,cisplatinum group,salidroside group and cisplatinum combined salidroside group.Then the mass size was measured by using the vemier caliper everyday.The xenograft tumor weight was measured by using the electronic scale and the tumor inhibiting rate was calculated.The immunohistochemistry method was adopted to verify that the xenograft tumor was undifferentiated squamous cell carcinoma.The tumor surrounding tissue in the xenograft group was taken as the control group.RT-PCR and Western blot were adopted to detect the expression levels of Eag1 mRNA and protein in mouse cervical cancer xenografts in each group.Results Kunming mice renograft tumor model was established by subcutaneous injection of cervical cancer U14 cells,the tumor formation rate was 100％.The tumor volume and tumor weight in the cisplatinum group,salidroside group and combined group were lower than those in the senograft group,the xenograft tumor volume and tumor weight in the combined xenograft group were significantly lower than those in the cisplatinum group and salidroside group (P＜0.05);the expressions of Eag1 mRNA and protein in the xenograft group,cisplatinum group and combined group were significantly higher than those in the control group,while which in the cisplatinum group,salidroside group and cisplatinum combined salidroside group were significantly lower than those in the xenograft group,the Eag1 expression level in the combined group was lower than that in the cisplatinum group and salidroside group,the difference was statistically significant(P＜ 0.05).Conclusion Salidroside can inhibit the growth of cervical cancer xenograft and Eag1 expression,and the effect in the combined use with cisplatinum is more significant.
