The inhibitor of tritium-estradiol bindings in rabbit nuclear type II estrogen receptors in a non-protein molecule in human endometrium and endometrial cancer

The inhibitor in tritium-estradiol binding to the estrogen receptor was found to specifically inhibit the nuclear type II estrogen receptors. This was shown to be a non-protein small molecule constituting the gamuma peak in the LII-20 chromatography of the inhibitor cytosol. (Conclusion)
