Description:
delta9-Tetrahydrocannabinol (delta9-THC), added to the limit of its solubility, did not compete with tritiated 17beta-estradiol for binding to estrogen receptor sites in mouse mammary or uterine cytosols. On sucrose density gradients of low-ionic strength, mammary cytosol labeled with [3H]estradiol exhibited a binding peak near the "8S" region typical of estrogen receptor whereas in cytosol labeled with delta9-[3H]THC binding was limited to the nonspecific 4- to 5S region. Differences in sedimentation properties and reciprocal competition studies strongly refute previous claims that delta-9-THC binds to estrogen receptor and that by so doing it directly acts as an estrogen.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Okey, A B -- Bondy, G P -- New York, N.Y. -- Science. 1978 Apr 21;200(4339):312-4.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/635586" target="_blank"〉PubMed〈/a〉
