Contraceptive progestins with androgenic properties stimulate breast epithelial cell proliferation

Philipp Bucher, Cathrin Brisken, Giovanna Ambrosini, Laura Battista, Céline Berthe Constantin, Valentina Scabia, Marie Shamseddin, Csaba Ferenc László, Fabio De Martino

Hormonal contraception exposes women to synthetic progesterone receptor (PR) agonists, progestins, and transiently increases breast cancer risk. How progesterone and progestins affect the breast epithelium is poorly understood because we lack adequate mode ...

Variably Scaled Kernels Improve Classification of Hormonally-Treated Patient-Derived Xenografts

Cathrin Brisken, Marie Shamseddin, Fabio De Martino, Francesco Marchetti

Little is known about the biological functions which are exerted by hormone receptors in physiological conditions. Here, we made use of the Mouse INtraDuctal (MIND) model, an innovative patient-derived xenograft (PDX) model, to characterize global gene exp ...

Characterization of circulating breast cancer cells with tumorigenic and metastatic capacity

Cathrin Brisken, Laura Battista, Georgios Sflomos

Functional studies giving insight into the biology of circulating tumor cells (CTCs) remain scarce due to the low frequency ofCTCs and lack of appropriate models. Here, we describe the characterization of a novelCTC-derived breast cancer cell line, designa ...

IL6/STAT3 Signaling Hijacks Estrogen Receptor α Enhancers to Drive Breast Cancer Metastasis

Cathrin Brisken, Sanjeev Kumar, Valentina Scabia

2020

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 ...

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 ...

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 ...

miR363-3p mediates maintenance of breast cancer stem cells (BCSCs) and predicts resistance to neoadjuvant chemotherapy and disease recurrence

Nicolas Mermod, Jean-Yves Meuwly, Cathrin Brisken, Valentina Scabia, Valérian Charles Robert Dormoy, Maryse Fiche, Ioannis Xenarios

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

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

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 high resolution LC-MS targeted method for the concomitant analysis of 11 contraceptive progestins and 4 steroids

Alexandre Béguin, Cathrin Brisken, Marc Moniatte, Jonathan Paz Montoya, Marie Shamseddin, Csaba Ferenc László, Fabio De Martino

In the context of hormonal contraception and hormone replacement therapy (HRT), many women are exposed to exogenous hormones. Current use of hormonal contraception with combined ethinyl estradiol and different progestins bestows a breast cancer relative ri ...

Two-Tier Mapper, an unbiased topology-based clustering method for enhanced global gene expression analysis

Kathryn Hess Bellwald, Cathrin Brisken, Jacques Rougemont, Rachel Marcone

Motivation: Unbiased clustering methods are needed to analyze growing numbers of complex data sets. Currently available clustering methods often depend on parameters that are set by the user, they lack stability, and are not applicable to small data sets. ...

Novel human cell line xenograft models of ER alpha-positive metastatic invasive lobular breast carcinoma as pre-clinical platforms for validating candidate genetic drivers

Jeremy Luterbacher, Cathrin Brisken, Georgios Sflomos, Wenhao Hou

Investigating cortactin as a genetic driver of disease progression in invasive lobular carcinoma

C/EBP alpha mediates the growth inhibitory effect of progestins on breast cancer cells

Cathrin Brisken, Valentina Scabia

Steroid hormones are key gene regulators in breast cancer cells. While estrogens stimulate cell proliferation, progestins activate a single cell cycle followed by proliferation arrest. Here, we use biochemical and genome-wide approaches to show that proges ...

Intraductal patient-derived xenografts of estrogen receptor α-positive breast cancer recapitulate the histopathological spectrum and metastatic potential of human lesions

Cathrin Brisken, Ayyakkannu Ayyanan, Laura Battista, Georgios Sflomos, Valentina Scabia, Valérian Charles Robert Dormoy, Maryse Fiche, Patrik Aouad

Estrogen receptor α-positive (ER-positive) or 'luminal' breast cancers were notoriously difficult to establish as patient-derived xenografts (PDXs). We and others recently demonstrated that the microenvironment is critical for ER-positive tumor cells; when ...

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

Cathrin Brisken, Ayyakkannu Ayyanan, Georgios Sflomos, Valentina Scabia, Dalya Ataca, 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 ...

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 ...

Patient-derived xenograft (PDX) models in basic and translational breast cancer research

Cathrin Brisken, Georgios Sflomos, Valentina Scabia

Patient-derived xenograft (PDX) models of a growing spectrum of cancers are rapidly supplanting long-established traditional cell lines as preferred models for conducting basic and translational preclinical research. In breast cancer, to complement the now ...

Adamts18 deletion results in distinct developmental defects and provides a model for congenital disorders of lens, lung, and female reproductive tract development

Cathrin Brisken, Marian Caikovski, Yakir Guri, Alessandra Piersigilli, Dalya Ataca

The ADAMTS family comprises 19 secreted metalloproteinases that cleave extracellular matrix components and have diverse functions in numerous disease and physiological contexts. A number of them remain 'orphan' proteases, among them ADAMTS18, which has bee ...
