Mechanisms of GnRH Action: Interactions Between GnRH-Stimulated Calcium-Phospholipid Pathways Mediatonadotropes. In rat pituitary cells, the GnRH receptor consists of two binding components of molecular weight 53,000 and 42,000 as revealed by photoaffinity labelling techniques (Iwashita and Catt, 1985). As with all peptide hormones, GnRH-receptor binding leads to activation of intracellular “secon

Intra-Ovarian Actions of Steroids in Regulation of Follicular Steroid Biosynthesist the culmination of each ovarian cycle. A secondary role of the follicle is the biosynthesis and secretion of a group of steroid hormones which serve many important functions in regulation of peripheral (i. e extra-ovarian) cells and tissues.

Interaction Between the Oocyte and the Granulosa Cells in the Preovulatory Folliclee genital ridge, will proliferate to form the granulosa cell layer of the secondary follicle (Brambell, 1962; Franchi et al., 1962). Throughout folliculogenesis the granulosa layer is divided into two cellular subpopulations: the peripheral granulosa cells which become part of the follicular wall an

Secretion of Oxytocin by the Corpus Luteum and its Role in Luteolysis in the Sheepction response during lactation. The active posterior pituitary principle was named oxytocin (Gr. Oxys, sharp; Tokos, birth) as a result of its action on the uterus which was first described by Dale (1906, 1909) and Blair-Bell (1909). These two actions of oxytocin have been described comprehensively

Evidence for Intratesticular Factors Which Mediate the Response of Leydig Cells to Disruption of Spe inhibiting hormones of the hypothalamus regulated the adenohypophysial secretion of luteinizing hormone (LH), follicle stimulating hormone (FSH), and prolactin (McCann, 1974; Neill, 1974). Studies of the action of these pituitary hormones led to the general acceptance that LH acts on the interstiti
