Abstract

OBJECTIVE

To study the effects of lithospermum extract on MCF-7 cell and estrogen and progestogen levels in mice.

METHOD

Cell growth curve and Western Blotting were used to do animal experiment.

RESULT

Lithospermum extract could inhibit the growth of MCF-7 cell. It could also inhibit the expression of ER and increase the expression of PR with large dose. After the mice were bred with Lithospermum, their serum estrogen and progestogen levels reduced, their uterus weight index decresed and uterus ER and PR levels increased. It could also improve the hyperplasia of uterus caused by tamoxifen.

CONCLUSION

Lithospermum extract can inhibit the growth of MCF-7 cell and inhibit the level of estrogen and progestogen in mice.
