The spatial organization of the genome in the nucleus plays a role in the regulation of gene expression. Whether co-regulated genes are subject to coordinated repositioning to a shared nuclear space is a matter of considerable interest and debate. We investigated the nuclear organization of estrogen receptor alpha (ERalpha) target genes in human breast(More)
The estrogen receptor alpha (ERα) is found predominately in the nucleus, both in hormone stimulated and untreated cells. Intracellular distribution of the ERα changes in the presence of agonists but the impact of different antiestrogens on the fate of ERα is a matter of debate. A MCF-7 cell line stably expressing GFP-tagged human ERα (SK19 cell line) was(More)
Auraptene is a prenyloxycoumarin from Citrus species with chemopreventive properties against colitis-related colon and breast cancers through a yet-undefined mechanism. To decipher its mechanism of action, we used a ligand-structure based approach. We established that auraptene fits with a pharmacophore involved in both the inhibition of(More)

Tocols are vitamin E compounds that include tocopherols (TPs) and tocotrienols (TTs). These lipophilic compounds are phenolic antioxidants and are reportedly able to modulate estrogen receptor β (ERβ). We investigated the molecular determinants that control their estrogenicity and effects on the proliferation of breast cancer cells. Docking experiments(More)
