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

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 ...

Optimized Modeling of Metastatic Triple-Negative Invasive Lobular Breast Carcinoma

Cathrin Brisken, Laura Battista, Georgios Sflomos

Simple Summary Invasive lobular carcinoma (ILC) is the second most common histologic subtype of breast cancer and is often detected at an advanced stage. Up to 30% of ILC cases relapse and present a challenge for treatment. Unfortunately, there are few mod ...

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 ...

Co-regulation of endothelial and myogenic cell fates through intercellular crosstalk in skeletal muscle

Umji Lee

Skeletal muscle is one of the most dynamic organs in the human body, which has a vigorous potential to regenerate and adapt to environmental changes. Depending on environments, skeletal muscle enables essential life activities to survive by controlling mov ...

Membrane expression of the estrogen receptor ER alpha is required for intercellular communications in the mammary epithelium

Cathrin Brisken, Stéphanie Cagnet

17 beta-Estradiol induces the postnatal development of mammary gland and influences breast carcinogenesis by binding to the estrogen receptor ER alpha. ER alpha acts as a transcription factor but also elicits rapid signaling through a fraction of ER alpha ...

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

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

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 ...

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

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 ...

Analysis of Mammary Gland Phenotypes by Transplantation of the Genetically Marked Mammary Epithelium

Cathrin Brisken, Duje Buric

The mammary gland is the only organ to undergo most of its development after birth and therefore particularly attractive for studying developmental processes. In the mouse, powerful tissue recombination techniques are available that can be elegantly combin ...

Control of Hoxd gene transcription in the mammary bud by hijacking a preexisting regulatory landscape

Denis Duboule, Guillaume Andrey, Jozsef Zakany, Anamaria Necsulea, Leonardo Beccari, Edgardo Rodriguez Carballo, Virginie Marcet

Vertebrate Hox genes encode transcription factors operating during the development of multiple organs and structures. However, the evolutionary mechanism underlying this remarkable pleiotropy remains to be fully understood. Here, we show that Hoxd8 and Hox ...

Endocrine hormones and local signals during the development of the mouse mammary gland

Cathrin Brisken, Dalya Ataca

Most of mammary gland development occurs postnatally under the control of female reproductive hormones, which in turn interact with other endocrine factors. While hormones impinge on many tissues and trigger very complex biological responses, tissue recomb ...

Progesterone and Overlooked Endocrine Pathways in Breast Cancer Pathogenesis

Cathrin Brisken, Kathryn Hess Bellwald, 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 and Wnt4 control mammary stem cells via myoepithelial crosstalk

Cathrin Brisken, Jacques Rougemont, Ayyakkannu Ayyanan, Marian Caikovski, Duje Buric, Renuga Devi Rajaram

Ovarian hormones increase breast cancer risk by poorly understood mechanisms. We assess the role of progesterone on global stem cell function by serially transplanting mouse mammary epithelia. Progesterone receptor (PR) deletion severely reduces the regene ...

Mechanisms underlying cell-fate determination in the mammary gland development

Duje Buric

Notch signaling pathway is an important developmental pathway and has been implicated in both mammary gland development and tumorigenesis. Several studies investigating Notch signaling in mouse mammary gland implied that Notch signaling is an important fac ...

Bicaudal C1 promotes pancreatic NEUROG3+ endocrine progenitor differentiation and ductal morphogenesis

Daniel Constam, Anne Grapin-Botton, Jacques Rougemont, Joan Goulley, Yung Hae Kim, Laurence Anne E Lemaire

In human, mutations in bicaudal C1 (BICC1), an RNA binding protein, have been identified in patients with kidney dysplasia. Deletion of Bicc1 in mouse leads to left-right asymmetry randomization and renal cysts. Here, we show that BICC1 is also expressed i ...
