Intraductal xenografts show lobular carcinoma cells rely on their own extracellular matrix and LOXL1

Cathrin Brisken, Giovanna Ambrosini, Ayyakkannu Ayyanan, Georgios Sflomos, Laura Battista, Philipp Bucher, Valentina Scabia, Maryse Fiche, Fabio De Martino, Patrik Aouad

Invasive lobular carcinoma (ILC) is the most frequent special histological subtype of breast cancer, typically characterized by loss of E‐cadherin. It has clinical features distinct from other estrogen receptor‐positive (ER+) breast cancers but the molecul ...

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

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

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

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

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 ...

Microfluidics-assisted fluorescence in situ hybridization for advantageous human epidermal growth factor receptor 2 assessment in breast cancer

Martinus Gijs, Raphaël Etienne Jean Trouillon, Huu Tuan Nguyen, Maryse Fiche, Seiya Matsuoka

Fluorescence in situ hybridization (FISH) is one of the recommended techniques for human epidermal growth factor receptor 2 (HER2) status assessment on cancer tissues. Here we develop microfluidics-assisted FISH (MA-FISH), in which hybridization of the FIS ...

Continuous quantification of HER2 expression by microfluidic precision immunofluorescence estimates HER2 gene amplification in breast cancer

Martinus Gijs, Ata Tuna Ciftlik, Diego Gabriel Dupouy, Maryse Fiche, Déborah Heintze

Chromogenic immunohistochemistry (IHC) is omnipresent in cancer diagnosis, but has also been criticized for its technical limit in quantifying the level of protein expression on tissue sections, thus potentially masking clinically relevant data. Shifting f ...

FLUORESCENCE IN SITU HYBRIDIZATION (FISH) ENHANCEMENT USING MICROFLUIDIC FLOW FOR AN ACCURATE, FAST AND ECONOMICAL ASSESSMENT OF HER2 STATUS IN BREAST CANCER

Martinus Gijs, Raphaël Etienne Jean Trouillon, Huu Tuan Nguyen, Maryse Fiche, Seiya Matsuoka

The fluorescence in situ hybridization (FISH) is the gold standard in human epidermal growth factor receptor 2 (HER2) status assessment in breast cancer. The dissemination of the technique is impeded by the cost of reagents and long experimental time. For ...

A Preclinical Model for ERα-Positive Breast Cancer Points to the Epithelial Microenvironment as Determinant of Luminal Phenotype and Hormone Response

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

Seventy-five percent of breast cancers are estrogen receptor α positive (ER(+)). Research on these tumors is hampered by lack of adequate in vivo models; cell line xenografts require non-physiological hormone supplements, and patient-derived xenografts (PD ...

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

Cathrin Brisken, Tamara Tanos, Georgios Sflomos, Ayyakkannu Ayyanan, Maryse Fiche, Maria Gutierrez Najera

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 ...

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

Cathrin Brisken, Maryse Fiche

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 ...

The Ret receptor tyrosine kinase pathway functionally interacts with the ERalpha pathway in breast cancer

Cathrin Brisken, Maryse Fiche

A limited number of receptor tyrosine kinases (e.g., ErbB and fibroblast growth factor receptor families) have been genetically linked to breast cancer development. Here, we investigated the contribution of the Ret receptor tyrosine kinase to breast tumor ...
