Abstract：
:The effect of 17-beta-estradiol (E2) on the induction of osteolytic lesions by estrogen receptor (ER)-negative breast cancer cells was investigated in 4-week-old female nude mice. Exposure to exogenous E2 was found to increase osteolytic areas on radiographs up to 5.3 times in mice inoculated intracardially with MDA-231 human breast cancer cells. The MDA-231 cells were ER-negative, both before inoculation, and after isolation from osteolytic lesions, and the corresponding cell cultures were insensitive to E2. The induction of skeletal lesions by E2 in this mouse model was mainly effectuated at the early development of bone metastases, since exposure to E2 for 8 days around MDA-231 inoculation increased osteolysis to the same level, as did E2 given throughout the entire 31-day experimental period, and because E2-exposure for just the final 14 days had no effect. Independently of exposure to E2, histology revealed cancer cells in hind limp long bones of approximately 80% of the mice, and tumors were absent in non-skeletal organs. In vitro studies showed that the number and activity of osteoclasts generated from mouse bone marrow cells were increased 5-6 times when co-cultured with MDA-231 cells. Addition of 0.1-10 nM E2 further dose-dependently increased the osteoclastogenesis and associated bone resorption in these co-cultures. In conclusion, E2 was found to increase the morbidity in mice inoculated with ER-negative MDA-231 cells, and to stimulate osteoclast formation and bone resorption in co-cultures of bone marrow cells and MDA-231, suggesting that the progression of osteolytic metastases by ER-negative breast cancer cells can be induced by E2 due to stimulation of osteoclastogenesis.
