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

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

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 ...

Lymphotoxin-Dependent B Cell-FRC Crosstalk Promotes De Novo Follicle Formation and Antibody Production following Intestinal Helminth Infection

Luc Xavier Marie Lebon, Ilaria Mosconi, Nicola Harris, Lalit Kumar Dubey

Secondary lymphoid tissues provide specialized niches for the initiation of adaptive immune responses and undergo a remarkable expansion in response to inflammatory stimuli. Although the formation of B cell follicles was previously thought to be restricted ...

Identification of genetic interactors of ypa2 in Schizosaccharomyces pombe

Manuela Moraru

In this study, the fission yeast Schizosaccharomyces pombe was used as a model system to study the cellular signaling that underlies cell cycle progression. Phosphorylation plays an important part in the regulation of this process. Kinases catalyze the tra ...

Identification and functional characterization of protein kinases that modulate Notch signaling under physiological conditions and in cancer

Chhavi Jain

The Notch signaling pathway is a key regulator of cell fate decisions in embryonic development and in adult tissue homeostasis. Mounting evidence suggests that Notch signaling is frequently deregulated in human neoplasms, where depending upon the cellular ...

Culture of preantral follicles in poly(ethylene) glycol-based, three-dimensional hydrogel: a relationship between swelling ratio and follicular developments

Jeffrey Alan Hubbell, Seung Tae Lee

This study was undertaken to examine how the softness of poly(ethylene) glycol (PEG)-based hydrogels, creating a three-dimensional (3D) microenvironment, influences the in vitro growth of mouse ovarian follicles. Early secondary, preantral follicles of 2we ...

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 ...

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 ...

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 ...

Identification of the Link Between the Hypothalamo-Pituitary Axis and the Testicular Orphan Nuclear Receptor NR0B2 in Adult Male Mice

Kristina Schoonjans

The small heterodimer partner (SHP, nuclear receptor subfamily 0, group B, member 2; NR0B2) is an atypical nuclear receptor known mainly for its role in bile acid homeostasis in the enterohepatic tract. We previously showed that NR0B2 controls testicular f ...
