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

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 ...

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 ...

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 ...

VEGFR-3 Neutralization Inhibits Ovarian Lymphangiogenesis, Follicle Maturation, and Murine Pregnancy

Didier Trono, Jeffrey Alan Hubbell, Melody Swartz, Witold Waldemar Kilarski, Joseph Rutkowski, Seung Tae Lee, Miriella Carmela Pasquier, Jong Eun Ihm, Vivianne Greenwood

Lymphatic vessels surround follicles within the ovary, but their roles in folliculogenesis and pregnancy, as well as the necessity of Lymphangiogenesis in follicle maturation and health, are undefined. We used systemic delivery of mF4-31C1, a specific anta ...

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 ...

Liver receptor homolog 1 is essential for ovulation

Johan Auwerx, Kristina Schoonjans, Chikage Mataki

Female fertility requires normal ovarian follicular growth and ovulation. The nuclear receptor liver receptor homolog 1 has been implicated in processes as diverse as bile acid metabolism, steroidogenesis, and cell proliferation. In the ovary, Lrh1 is expr ...

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 ...

SPC4, SPC6, and the novel protease SPC7 are coexpressed with bone morphogenetic proteins at distinct sites during embryogenesis

Daniel Constam

In the present study, we screened for subtilisin-like proprotein convertases (SPCs) that potentially regulate the activation of known growth factors during embryonic development. We isolated a novel protease, SPC7, as well as several known SPCs. SPC7, like ...

Export of mRNA from microinjected nuclei of Xenopus laevis oocytes

Lukas Kühn

Export of mRNA from the nucleus to the cytoplasm was studied in mature Xenopus laevis oocytes. In vitro transcribed, capped 32P-labeled mRNA was microinjected into nuclei, and its appearance in the cytoplasm measured by counting radioactivity or by RNA ext ...

Follicular maturation, luteinization and first meiotic division in oocytes after inhibiting mitochondrial function in mice with chloramphenicol

Friedrich Beermann

A significant number of diploid oocytes is ovulated from adult NMRI/Han mice treated with high doses of gonadotrophins. This inhibition of the first meiotic division is very likely caused by an altered communication between the germ cell and the surroundin ...
