90 YEARS OF PROGESTERONE Progesterone receptor signaling in the normal breast and its implications for cancer

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 ...

Ovary-specific depletion of the nuclear receptor Nr5a2 compromises expansion of the cumulus oophorus but not fertilization by intracytoplasmic sperm injection

Kristina Schoonjans

The orphan nuclear receptor, liver receptor homolog-1 (aka Nuclear receptor subfamily 5, Group A, Member 2 (Nr5a2)), is widely expressed in mammalian tissues, and its ovarian expression is restricted to granulosa cells of activated follicles. We employed t ...

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 ...

Murine ovarian follicle culture in PEG-hydrogel: Effects of mechanical properties and the hormones FSH and LH on development

Jeffrey Alan Hubbell, Seung Tae Lee, Jong Eun Ihm

The development of an in vitro culture system, comparable to the in vivo environment in terms of effects on oocyte growth and development, could provide a valuable experimental tool for studying the mechanisms governing oocyte development as well as practi ...

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 ...

The Orphan Nuclear Receptor Nr5a2 Is Essential for Luteinization in the Female Mouse Ovary

Kristina Schoonjans

In the ovary, the follicular granulosa cells express the nuclear receptor Nr5a2 (nuclear receptor subfamily 5 group A member 2), also known as liver receptor homolog-1, and after ovulation, Nr5a2 expression persists in the corpus luteum. Previous studies d ...

Liver receptor homolog-1 is essential for pregnancy

Kristina Schoonjans

Successful pregnancy requires coordination of an array of signals and factors from multiple tissues. One such element, liver receptor homolog-1 (Lrh-1), is an orphan nuclear receptor that regulates metabolism and hormone synthesis(1). It is strongly expres ...

Vertical transmission of a Drosophila endosymbiont via cooption of the yolk transport and internalization machinery

Bruno Lemaitre, Fanny Schüpfer, Juan Camilo Paredes Escobar, Jeremy Keith Herren

Spiroplasma is a diverse bacterial clade that includes many vertically transmitted insect endosymbionts, including Spiroplasma poulsonii, a natural endosymbiont of Drosophila melanogaster. These bacteria persist in the hemolymph of their adult host and exh ...

Development of an in vitro microenvironment for maturing oocytes

Jong Eun Ihm

The development of in vitro culture systems, comparable to the in vivo microenvironment in terms of effect on the oocyte growth and development could provide a valuable experimental tool for studying the mechanisms governing folliculogenesis. This tool mig ...
