Androgen Receptor Signaling in in vivo models of Estrogen Receptor-positive Breast Cancer and Normal Breast Epithelium

Andrea Agnoletto

Steroid hormone receptors (HRs) are ligand-activated transcription factors that play a pivotal role in breast development and carcinogenesis. It is well established that estrogen receptor (ER) signaling is a major proliferative driver in estrogen receptor ...

TGF beta-mediated MMP13 secretion drives myoepithelial cell dependent breast cancer progression

Cathrin Brisken, Andrea Agnoletto

Ductal carcinoma in situ (DCIS) is a non-obligate precursor of invasive breast cancer. Virtually all women with DCIS are treated, despite evidence suggesting up to half would remain with stable, non-threatening, disease. Overtreatment thus presents a press ...

Estrogen receptor signaling in the human breast epithelium

Céline Berthe Constantin

Breast cancer is the most diagnosed malignancy in women worldwide, making effective prevention strategies crucial. Hormonal contraceptives, consisting of a synthetic progesterone receptor agonist alone or in combination with an estrogen, are used by millio ...

Role of the androgen receptor in the human breast epithelium

Fabio De Martino

Breast cancer is the most common malignancy in women worldwide and understanding the risk factors affecting it is key for prevention. The relative risk of developing breast cancer is related to exposure to both endogenous hormones and exogenous natural and ...

The secreted protease Adamts18 links hormone action to activation of the mammary stem cell niche

Philipp Bucher, Cathrin Brisken, Giovanna Ambrosini, Rachel Marcone, Céline Berthe Constantin, Dalya Ataca, Marie Shamseddin, Csaba Ferenc László, Marian Caikovski, Patrik Aouad

Estrogens and progesterone control breast development and carcinogenesis via their cognate receptors expressed in a subset of luminal cells in the mammary epithelium. How they control the extracellular matrix, important to breast physiology and tumorigenes ...

A novel culture method that sustains ER alpha signaling in human breast cancer tissue microstructures

Cathrin Brisken, Georgios Sflomos

Background Estrogen receptor alpha (ER alpha) signaling is a defining and driving event in most breast cancers; ER alpha is detected in malignant epithelial cells of 75% of all breast cancers (classified as ER-positive breast cancer) and, in these cases, E ...

90 YEARS OF PROGESTERONE Progesterone receptor signaling in the normal breast and its implications for cancer

Cathrin Brisken, Valentina Scabia

Progesterone is considered as the pregnancy hormone and acts on many different target tissues. Progesterone receptor (PR) signaling is important for normal development and the physiologic function of the breast and impinges on breast carcinogenesis. Both s ...

Adamts18 Function in Mammary Gland Development

Dalya Ataca

Ovarian hormones control mammary gland development and impinge on breast carcinogenesis acting via their cognate receptors in the luminal epithelium. The extracellular matrix has a key role in physiology and disease but how the two are linked is poorly und ...

Oestrogen receptor alpha AF-1 and AF-2 domains have cell population-specific functions in the mammary epithelium

Cathrin Brisken, Georgios Sflomos, Valentina Scabia, Patrik Aouad, Ayyakkannu Ayyanan, Dalya Ataca, Stéphanie Cagnet

Oestrogen receptor alpha (ER alpha) is a transcription factor with ligand-independent and ligand-dependent activation functions (AF)-1 and -2. Oestrogens control postnatal mammary gland development acting on a subset of mammary epithelial cells (MECs), ter ...

Progestins used for hormonal contraception in Switzerland: study of their effects on the breast epithelium

Marie Shamseddin

Breast cancer is the most commonly diagnosed cancer and the most common cause of cancer death among women. Hormones have been shown to have a key role in breast development and carcinogenesis. Repeated activation of progesterone receptor (PR) signaling as ...

In vivo reprogramming of non-mammary cells to an epithelial cell fate is independent of amphiregulin signaling

Cathrin Brisken, Stéphanie Cagnet

AREG-/- mice demonstrate impaired mammary development and form only rudimentary ductal epithelial trees, however, AREG-/- glands are still capable of undergoing alveologenesis and lactogenesis during pregnancy. Transplantation of AREG-/- mammary epithelial ...

Progesterone and Overlooked Endocrine Pathways in Breast Cancer Pathogenesis

Kathryn Hess Bellwald, Cathrin Brisken, Rachel Marcone

Worldwide, breast cancer incidence has been increasing for decades. Exposure to reproductive hormones, as occurs with recurrent menstrual cycles, affects breast cancer risk, and can promote disease progression. Exogenous hormones and endocrine disruptors h ...

Progesterone/RANKL Is a Major Regulatory Axis in the Human Breast

Cathrin Brisken, Georgios Sflomos, Ayyakkannu Ayyanan, Tamara Tanos

Estrogens and progesterones are major drivers of breast development but also promote carcinogenesis in this organ. Yet, their respective roles and the mechanisms underlying their action in the human breast are unclear. Receptor activator of nuclear factor ...

ER and PR signaling nodes during mammary gland development

Cathrin Brisken, Tamara Tanos, Lucia Jimenez Rojo

The ovarian hormones estrogen and progesterone orchestrate postnatal mammary gland development and are implicated in breast cancer. Most of our understanding of the molecular mechanisms of estrogen receptor (ER) and progesterone receptor (PR) signaling ste ...

Mig6 is a sensor of EGF receptor inactivation that directly activates c-Abl to induce apoptosis during epithelial homeostasis

Oliver Hantschel

A fundamental aspect of epithelial homeostasis is the dependence on specific growth factors for cell survival, yet the underlying mechanisms remain obscure. We found an "inverse" mode of receptor tyrosine kinase signaling that directly links ErbB receptor ...

Self-organization is a dynamic and lineage-intrinsic property of mammary epithelial cells

Loss of organization is a principle feature of cancers; therefore it is important to understand how normal adult multilineage tissues, such as bilayered secretory epithelia, establish and maintain their architectures. The self-organization process that dri ...

ID4 regulates mammary gland development by suppressing p38MAPK activity

Yiming Li, Cathrin Brisken, Xiuwei Zhang, Jun Dong, Marian Caikovski

The ID family of helix-loop-helix proteins regulates cell proliferation and differentiation in many different developmental pathways, but the functions of ID4 in mammary development are unknown. We report that mouse Id4 is expressed in cap cells, basal cel ...

Two distinct mechanisms underlie progesterone-induced proliferation in the mammary gland

Cathrin Brisken, Ayyakkannu Ayyanan, Marian Caikovski

The mouse mammary gland develops postnatally under the control of female reproductive hormones. Estrogens and progesterone trigger morphogenesis by poorly understood mechanisms acting on a subset of mammary epithelial cells (MECs) that express their cognat ...

Antagonistic roles of Notch and p63 in controlling mammary epithelial cell fates

Cathrin Brisken

The breast epithelium has two major compartments, luminal and basal cells, that are established and maintained by poorly understood mechanisms. The p53 homolog, p63, is required for the formation of mammary buds, but its function in the breast after birth ...

Role of canonical Wnt signaling in mammary gland development

The female reproductive hormones estrogens, progesterone, and prolactin control postnatal breast development and are important to breast carcinogenesis. In particular, exposure to progesterone is tightly linked to breast cancer risk. Using the mouse as a m ...
