Abstract
Homeobox genes, which code for families of transcription factors, act at the top of genetic hierarchies. HOX genes specify positional identity during development, and in adult tissues, regulate differentiation and proliferation. Most ovarian carcinomas are derived from the ovarian surface epithelium (OSE). In contrast to other carcinomas, OSE differentiates further with neoplastic progression and acquires Mtillerian duct-derived epithelial properties. I tested the hypothesis that growth and differentiation in ovarian carcinogenesis are regulated by HOX genes.

Abstract
Abnormal DNA methylation at imprinted and non-imprinted genes has been associated with spermatogenesis failure. However, little information is available regarding DNA methylation at those genes in men affected by severe male factor infertility. We hypothesized a higher incidence of aberrant DNA methylation would be present in the ejaculate and testicular sperm of men affected by severe male factor infertility compared to that in fertile control men. Furthermore, we hypothesized abnormal DNA methylation would also affect non-imprinted genes in the sperm of men affected by severe oligozoospermia.

Abstract
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 homeostasis, it is also produced in the central nervous system participating in the regulation of pituitary hormone secretion. Administration of ANP through both central and peripheral routes has been shown to inhibit secretion of luteinizing hormone (LH) in the gonadectomized rat model.

Abstract
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 stimulates the synthesis and release of both luteinizing hormone and follicle stimulating hormone from the anterior pituitary. In addition, GnRH - GnRH receptor binding acts locally to regulate human chorionic gonadotropin secretion in the placenta and steroidogenesis in the ovary. The objective of this thesis was to isolate and characterize the gene for the GnRH receptor in human.

Abstract
With the increasing use of assisted reproductive techniques (ART) every year, concerns have been raised regarding the possible effect these procedures have on the health of the children procured by them. Although patients born via ART are usually healthy, studies have associated these procedures with increased incidence of low birth weight (LBW), chromosomal abnormalities, birth defects and imprinting disorders. No study has proposed a single defined cause for any of these defects in ART infants, however it is believed that they may be due to both the invasiveness of ART and to genetic defects that are at the root of the infertility in the parents. In this study, changes in the methylation of the H19 and IGF2 imprinting control region 1 (ICR1) were investigated for both ART (n=92) and naturally conceived controls (n=19) using pyrosequencing.

Abstract
Human newborns exposed in utero to maternally administered SSRIs such as fluoxetine (FX) have an increased risk of adverse pregnancy outcomes including poor neonatal adaptation. This comprises respiratory difficulty, jitteriness, cyanosis when feeding and persists for several days after birth. Several potential mechanisms underlying these symptoms have been proposed: 1) acute toxicity to the drugs (i.e. serotonin syndrome), 2) withdrawal syndrome due to the sudden discontinuation of maternal-fetal placental drug transfer at birth or 3) an SSRIs-elicited alteration in fetal brain development. However, the actual mechanism has not been elucidated.
