MCF-7 human breast cell
METHODS: For       hybridization to the array, we prepared RNA from MCF-7 human breast cell tumors,        isolated from our athymic nude mouse xenograft model of acquired tamoxifen       resistance during estrogen-stimulated, tamoxifen-sensitive, and       tamoxifen-resistant growth.
