Is There a Special Role for Ovarian Hormones in the Pathogenesis of Lobular Carcinoma?

Lobular carcinoma represent the most common special histological subtype of breast cancer, with the majority classed as hormone receptor positive. Rates of invasive lobular carcinoma in postmenopausal women have been seen to increase globally, while other ...

The Ovulatory Signal Precipitates LRH-1 Transcriptional Switching Mediated by Differential Chromatin Accessibility

Kristina Schoonjans

In the ovary, follicular growth and maturation are complicated processes that involve a series of morphological and physiological changes in oocytes and somatic cells leading to ovulation and luteinization, essential processes for fertility. Given the comp ...

Palladium(II)-Stabilized Pyridine-2-Diazotates: Synthesis, Structural Characterization, and Cytotoxicity Studies

Paul Joseph Dyson, Alexander Tskhovrebov, Tina Riedel

Well-defined diazotates are scarce. Here we report the synthesis of unprecedented homoleptic palladium(II) diazotate complexes. The palladium(II)-mediated nitrosylation of 2-aminopyridines with NaNO2 results in the formation of metal-stabilized diazotates, ...

Water soluble derivatives of platinum carbonyl Chini clusters: synthesis, molecular structures and cytotoxicity of [Pt-12(CO)(20)(PTA)(4)](2-) and [Pt-15(CO)(25)(PTA)(5)](2-)

Paul Joseph Dyson, Lucinda Kate Batchelor, Silvia Ruggieri

The reactions of Pt-3n(CO)(6n) (n = 2-5) homoleptic Chini-type clusters with increasing amounts of 1,3,5-triaza-7-phosphaadamantane (PTA) result in the stepwise substitution of one terminal CO ligand per Pt-3 triangular unit up to the formation of [P ...

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 ...

Varying the metal to ethacrynic acid ratio in ruthenium(ii)/osmium(ii)-p-cymene conjugates

Paul Joseph Dyson, Catherine Marie Amélie Clavel, Mylène Soudani, Emilia Paunescu

Following the identification of a ruthenium(II)-arene complex with an ethacrynic acid-modified imidazole ligand, which inhibits glutathione transferase (GST) and is cytotoxic to chemo-resistant cancer cells, a series of structurally related ruthenium(II)- ...

Correlating microscopy techniques and ToF-SIMS analysis of fully grown mammalian oocytes

Sami Rtimi

The 2D-molecular thin film analysis protocol for fully grown mice oocytes is described using an innovative approach. Time-of-flight secondary ion mass spectrometry (ToF-SIMS), scanning electron microscopy (SEM), atomic force microscopy (AFM) and optical mi ...

Nonsteroidal Anti-inflammatory-Organometallic Anticancer Compounds

Paul Joseph Dyson, Rosario Scopelliti, Emilia Paunescu, Mylène Soudani, Sarah Mcarthur

Compounds that combine metal-based drugs with covalently linked targeted organic agents have been shown, in some instances, to exhibit superior anticancer properties compared to the individual counterparts. Within this framework, we prepared a series of or ...

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 ...
