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 …
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…
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…
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…
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…
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…
