Abstract:
AIM To investigate the effect of tamoxifen on the proliferation of the anterior pituitary cell of rats and its mechanism. METHODS Primary culture of the anterior pituitary cell of rats and 3H TdR incorporation method were applied. The changes of cell morphology were observed directly by electric microscope. RESULTS Tamoxifen could inhibit the proliferation of the anterior pituitary cell of rats. The inhibitory effect of tamoxifen (0 1 ?mol?L -1 ) could be reversed by estrogen.The classical apoptotic changes appeared in the cells after tamoxifen incubation for 48 h. CONCLUSION Tamoxifen can inhibit the proliferation of the anterior pituitary cell of rats and resultin the cell apoptosis.
