This thesis investigated the expression and regulation of cytochrome P450s, aromatase (P450arom) and cholesterol side chain cleavage (P450scc) enzyme mRNAs in human granulosa-luteal cells using reverse transcription-polymerase chain reaction (RT-PCR). The two enzymes are instrumental in steroid hor…
Activin A (homodimer of inhibin βA-subunit) is known to increase inhibin βB-subunit and inhibin B (heterodimer of inhibin α- and βB-subunit) levels and decrease progesterone accumulation in human granulosa cells. Growth differentiation factor 9 (GDF9) is a potent paracrine regul…
These studies examined the effects of prostaglandin-F[sub 2a] (PGF[sub 2a]) on progesterone and 178-estradiol (estradiol) production, as well as DNA and PGF[sub 2a]-receptor (PGF[sub 2a]-R) mRNA levels, in the human granulosa-luteal cell (GLC). Additionally, the interactions of PGF[sub 2a] with hum…
The present study was conducted to investigate the hypothesis that membrane phosphoinositide breakdown may participate in the actions of luteinizing hormone-releasing hormone (LHRH) on hormone production in the rat ovary. In granulosa cells prelabeled with [³H]-arachidonic acid or [³H]-inositol, tr…
There is increasing evidence to suggest that activin can function as an autocrine/paracrine regulator in various tissues, including the reproductive system. At the cellular level, activin acts via a family of activin receptor (ActR) subtypes which includes two type I (ActRI and ActRLB) and two type…
In order to characterize and compare the pattern of inhibin production in the follicular phase between patients of the clomiphene citrate/human menopausal gonadotropin (hMG) and Buserelin/hMG protocols in in-vitro fertilization, serum inhibin levels from 20 patients in each protocol were measured. …
This thesis work is focused on studies of sperm antigen: its purification and antifertility effect, its "internal image" by use of anti-idiotypic antibodies, and its capacity to induce antibodies of IgA class. Mouse sperm acrosomal antigens that react with a monoclonal antibody generated against mo…
Superovulation causes detrimental effects, including embryonic loss and implantation failure. This study determined potential roles for insulin-like growth factor (IGF-I) in uterine environment regulation and preimplantation development, in conjunction with the detrimental effects of superovulation…
A delicate balance of steroid and gonadotrophic hormones is essential for intrafollicular oocyte maturation and successful fertilization and embryonic development. Previous studies have demonstrated that a superovulatory dose of pregnant mare serum gonadotrophin (PMSG) has excessive gonadotrophic a…
A sperm specific and species conserved monoclonal antibody (HS-63) was shown to inhibit in vitro fertilization of mouse oocytes and human sperm penetration to zona-free hamster ova. The sperm antigen (SA-63) which reacts with HS-63 was found to be localized on the sperm acrosome. Following sperm ca…
Aberrant epidermal growth factor receptor (EGFR) activity contributes to the development of epithelial ovarian cancer (EOC), a common and lethal female malignancy. Elucidating the regulation of EGFR function will improve treatments for EOC and the survival of patients. This study aims to elucidate …
Ovarian cancer is the sixth most common cancer and the fifth leading cause of cancer-related death among women in developed countries. There is increasing evidence suggesting that the hormonal environment of the normal ovarian surface epithelium (OSE) and ovarian epithelial cancer (OEC) cells is as…
An excitatory role for norepinephrine (NE) in the regulation of luteinizing hormone (LH) release was first suggested when it was demonstrated that noradrenergic receptor antagonists were able to block ovulation. More recently it has been proposed that NE has both an excitatory role and an inhibitor…
Atrial natriuretic peptide (ANP) of atrial myocyte origin, has been shown to play a role in the diuresis, natriuresis, and antagonism of angiotensin and vasopressin. However, it is now apparent that in addition to the production of the peptide in the heart and in its role in fluid and electrolyte h…
The distintegrin-like and metalloproteinase with thrombospondin repeats (ADAMTS) are members of a gene family of secreted, multidomain and multifunctional proteinases that are able to proteolytically degrade a diverse array of cellular, extracellular and extracellular matrix (ECM) substrates. We ex…
Pre-eclampsia remains one of the most common causes of maternal mortality in the developed world, and we still have no known effective prophylaxis and proven modifiers. The recent successful clinical trial of recombinant human activated protein C (rhAPC) in the management of SIRS (systemic inflamma…
Ovarian cancer is the most lethal gynecological cancer in the Western world, but comparatively little is known about its development. Epithelial ovarian carcinomas are thought to originate in the ovarian surface epithelium (OSE), i.e. the mesothelium covering the ovary, but experimental evidence fo…
The gonadotropin - releasing hormone (GnRH) receptor is a plasma membrane associated receptor and a member of the GTP - binding protein coupled receptor family. The interaction of the ligand, GnRH, and the GnRH receptor is a critical event in the endocrine control of reproduction. This coupling sti…
In order to characterize and compare the pattern of inhibin production in the follicular phase between patients of the clomiphene citrate/human menopausal gonadotropin (hMG) and Buserelin/hMG protocols in in-vitro fertilization, serum inhibin levels from 20 patients in each protocol were measured. …
It is increasingly apparent that GnRH-II acts as an autocrine/paracrine regulator in non-pituitary tissues, in addition to its role in the regulation of gonadotropin synthesis, and is an important player in cancer cell biology. High levels of GnRH-II and GnRHR in malignant ovarian tumors as compare…
