Abstract Introduction Vaginal dryness is a frequent complaint, especially in post-menopausal women. The physiology underlying the production of vaginal lubrication response to arousing stimuli established; however, no current pharmacological agents successfully target mechanisms utilizing this physiology. Previous research from our lab has demonstrated that female methamphetamine (meth) users e...
Endocrine therapy-resistant estrogen receptor-positive (ER(+)) breast cancer is the most common cause of breast cancer death. Miller and colleagues demonstrate that ligand-independent ER activity promotes the growth of breast cancer cells through CDK4/E2F. As an independent event, the phosphatidylinositol 3-kinase (PI3K) pathway is also upregulated in endocrine therapy-resistant cells. Promisin...
Bidirectional cross talk between members of the human epidermal growth factor family of receptors (HER) and the estrogen receptor (ER) is believed to underlie resistance mechanisms that develop in response to treatment with anti-HER agents and endocrine therapy. We investigated the interaction between HER2, HER3 and the ER in vitro using human embryonic kidney cells transfected with human HER2,...
Hormone replacement therapy (HRT) affects the incidence and potential progression of colorectal cancer (CRC). As HRT primarily consists of estrone sulfate (E1S), understanding whether this conjugated estrogen is transported and metabolized in CRC will define its potential effect in this malignancy. Here, we show that a panel of CRC cell lines (Colo205, Caco2, HCT116, HT-29) have steroid sulfata...
PURPOSE Selective estrogen receptor modulators (SERM) are used for the treatment and prevention of breast cancer (tamoxifen) and osteoporosis (raloxifene). Mechanisms of tamoxifen-resistance in breast cancer are incompletely understood but current research is focused on crosstalk between growth factor receptors and the estrogen receptor alpha (ERalpha) pathway. There is increasing clinical use ...
