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

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 ...

Background: Sternbergia clusiana belongs to the Amaryllidaceae family and is recognized for the valuable biological activity of its major bioactive compounds. The aim of the current is to evaluate the anticancer effects of the ethanolic bulb extract of Ste ...

Metastasis is the process by which cancer cells from the primary tumor travel through the blood stream to generate a secondary tumor site in a distant organ. Although very few cells are able to make this journey, the resulting effects are dire since most c ...

Targeting the Progesterone Receptor in Breast Cancer: Mind the Short Form!

Cathrin Brisken, Carlos Henrique Venturi Ronchi

The presurgical window of opportunity trial (WOT) MIPRA provides evidence that neoadjuvant treatment with the prog-esterone receptor (PR) antagonist mifepristone (RU486) may benefit patients with estrogen receptor-positive (ER+) breast cancer characterized ...

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 ...

EPFL2022

Compared to estrogen receptor-negative (ER-) breast cancer (BC), ER+ BC often manifests with a latent disease that recurs decades after initial diagnosis. The mechanisms governing dormancy and distant recurrence of ER+ tumors remain elusive due to the lack ...

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

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

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 ...

Estrogen hormones are implicated in a majority of breast cancers and estrogen receptor alpha (ER), the main nuclear factor mediating estrogen signaling, orchestrates a complex molecular circuitry that is not yet fully elucidated. Here, we investigated geno ...

OXFORD UNIV PRESS2021

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 ...
