It is prevailingly thought that estrogen signaling is not involved in development of estrogen receptor (ER)-negative breast cancer. However, there is evidence indicating that ovariectomy prevents the development of both ER-positive and -negative breast cancer, suggesting that estrogen signaling is involved in the development of ER-negative breast cancer.(More)
Antiestrogens such as tamoxifen (TAM) provided a successful treatment for estrogen receptor (ER)-positive breast cancer for the past four decades. However, most breast tumors are eventually resistant to TAM therapy. The molecular mechanisms underlying TAM resistance have not been well established. Recently, we reported that breast cancer patients with(More)
Estrogen signaling is essential in the initiation and development of neoplasia in mammary gland. In the past several decades, extensive efforts have been dedicated to understand the underlying mechanisms of this important signaling pathway in mammary carcinogenesis, which have facilitated the development of anti-estrogen therapy, the first targeted therapy(More)
