The effects of oxytocin (OT) and the OT-analogue F314 were investigated on xenografts of mouse mammary and colon carcinomas (TS/A and C26 tumors) and of rat mammary carcinoma (D-R3230AC). In all cases, proliferation was previously assessed by cell counting in cultured cell lines, whereas tumor growth was checked by serial measures of tumor volume and by evaluation of tumor weight at the end of the experiment. Both cell proliferation and tumor growth were inhibited by OT and F314. These data support previous observations on the inhibitory effect of OT and F314 on the growth of MCF7, T47D and MDA-MB231 human breast cancer cell lines and open new prospects for testing the effect of this hypothalamic hormone and its analogues on the control of breast carcinoma growth.
