Abstract:Objective To investigate the effects of ATRA on established endometrial cancer bearing nude mice modle. Methods :Nude mice with transplanted HEC-1 tumor were randomly divided into five groups: middle-dose group(A group),high-dose group(B group), cisplatin group(C group),different time group(D group) ,blank control group (E group) . During the period of treatment,we measured the tumor size and drawed the growth curve of the tumors,The inhibitive rates of the tumor in nude mice was observed and detected the expression the c-met with the method of RT-PCR。Results: The inhibitive rate of the tumor was lower in middle-dose group than in high-dose group and cisplatin group (40.18% VS 67.34%,68.06%),but there is no difference in death rate of B group and C group,ATRA has inhibitive effect on c-met expression in tumor, the rate of c-met expression in tumor in group A、B and D is significant lower in group C and E. The c-met expression in tumor of group A and B group were similar to D group. Clusions:ATRA can inhibit the growth of tumor,which may be through the path of c-met by inhibiting the HGF/c-met.ATRA may be a potential drug to treat the endometrial cancer.but in our experimental study of ATRA,we discover the limitations of ATRA,It is necessary that ATRA comibined with other drugs can further inhibit the growth of tumor. |
