6. The roles of the plasminogen activator and matrix metalloproteinase systems in ovulation and corpus luteum formation
Sammanfattning : Proteases of the plasminogen activator (PA) and the matrix metalloproteinase (MMP) enzyme systems are expressed in the ovulatory follicle and in the developing corpus luteum (CL). However, the functional role of these extracellular degrading protease systems in the ovulatory and CL development processes remains elusive. LÄS MER
7. The role of leptin in zebrafish (Danio rerio) : Novel insights into appetite regulation and reproduction
Sammanfattning : The hormone leptin is a peripheral metabolic signal and an important regulator of energy balance. In mammals, leptin acts on the appetite centers in the hypothalamus, causing anorexigenic functions by inhibiting food intake. It is also considered as a link between the nutritional status and the endocrine reproductive axis. LÄS MER
8. The Ovulatory Process. Studies in the human and the rabbit
Sammanfattning : Background and general summary: Ovulation is the cascade of events ending with follicular rupture and oocyte extrusion. This ovulatory process is triggered by the LH surge, which induces biochemical and biophysical alterations within the preovulatory follicle. LÄS MER
9. Matrix degrading proteases in the ovary : expression and function
Sammanfattning : Extracellular matrix degrading proteases from the plasminogen (plg) activator (PA) and the matrix metalloproteinase (MMP) systems have been implicated as important mediators of ovulation and corpus luteum (CL) formation and regression. The aim of this thesis was to investigate the expression and regulation of PAs and MMPs in the ovary and to examine their functional roles for CL formation and function. LÄS MER
10. Granulosa cell apoptosis: Transcriptional regulation by the nuclear progesterone receptor
Sammanfattning : Ovarian follicle atresia caused by granulosa cell apoptosis is a central process in normal female physiology. Progesterone has been reported to be a survival factor in granulosa cells at several developmental stages. LÄS MER
