We sought to define mechanisms of estradiol (E) signaling in a solid breast tumor model using gene expression profiling. ER+ T47D-Y human breast cancer cells were grown as xenografts in ovariectomized nude mice under four conditions: i. E for 8 weeks (E); ii. without E for 8 weeks (controls, C); iii. E for 7 weeks followed by 1 week of E withdrawal (Ewd), or iv. E for 8 weeks with Tamoxifen for the last week (E+Tam). E-regulated genes were defined as those that differed significantly between C and E, and/or between E and Ewd. These protocols generated 188 in vivo E-regulated genes that showed two major patterns of regulation. Approximately 46% returned to basal states after Ewd (Class I genes); 53% did not (Class II genes). In addition, more than 70% of Class II regulated genes also failed to reverse in response to Tamoxifen. These genes may be interesting to study hormone resistance issues. A subset of in vivo E-regulated genes appears on lists of clinical \\\"ER discriminator \\\" genes. These may be useful therapeutic targets or markers of E activity. Comparison of in vivo E-regulated genes to those regulated in identical cells in vitro after 6 and 24 h of E treatment demonstrate only 11% overlap. This indicates the extent to which gene expression profiles are uniquely dependent on hormone treatment times and the cellular microenvironment."; prov:wasQuotedFrom pubmed:16239301 . sub:_4 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:16239301; prov:wasDerivedFrom beldoc:, sub:_3 . } sub:pubinfo { this: dct:created "2014-07-03T14:30:38.913+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
