Insulin, an established mitogen that promotes breast cancer cell growth, has been implicated in the link between obesity and an increased risk of breast cancer. However, the current understanding of signaling pathways that mediate the mitogenic actio

The cellular response to circulating sex steroids is more than the sum of individual hormone actions, instead representing an interplay between activities of the evolutionarily related steroid hormone receptors. An example of this interaction is in b

This transcript is based on my The Year in Basic Science lecture at ENDO 2008. I reviewed current data surrounding hormone replacement therapy and the relationship between systemic estrogen plus progestin (E+P) treatment and increased breast cancer r

Until recently, the study of nuclear receptor (NR) function in breast cancer biology has been largely limited to estrogen and progesterone receptors. The development of reliable gene expression arrays, real-time quantitative RT-PCR, and immunohistoch

In the 47 yr since the first evidence for a steroid hormone receptor was presented at an international congress to an audience of five persons, the concept of “alternative approach” has played an important role in providing new understanding. By

Estrogen receptor alpha (ERalpha) negative breast tumors often present with enhanced expression and/or activation of growth factor receptors, resulting in increased growth factor signaling and hyperactivation of MAPK (ERK1 and ERK2). We have pre-viou

Recent clinical studies estimate that 60-70% of human ovarian and breast cancers overexpress the estrogen receptor (ER). However, despite the established mitogenic effects of estrogen in these tumors, proliferative markers of hormone action are limit

Cross-talk between insulin-like growth factor (IGF)- and estrogen receptor (ER)-signaling pathways results in synergistic growth. We show here that estrogen enhances IGF signaling by inducing expression of three key IGF-regulatory molecules, the type

Autoregulation is a control mechanism common to several proteins of the steroid/thyroid hormone receptor superfamily. In this work, the effect of androgens and antiandrogens on the expression of the human androgen receptor (hAR) in prostate and breas

We studied the effects of interleukin-1 alpha (IL-1) and tumor necrosis factor-alpha (TNF), alone and in combination, on MCF-7 breast cancer cells to determine whether these cytokines alter cell growth, TNF gene expression, and TNF secretion. We foun
