Abstract:
This is a review of original data concerning new extra- and intracellular regulators of rabbit ovarian functions. Effects of some hormones including leptin, ghrelin, oxytocin, arginine-vasotocin, endothelin (ET-1), gonadotropin releasing hormone (GnRH), adrenocorticotropic hormone (ACTH), growth factors such as insulin-like growth factor-I (IGF-I), epidermal growth factor (EGF), nuclear peroxisome proliferator-activated receptor gamma (PPARγ), pharmacological regulators of some protein kinases such as protein kinase A (PKA), mitogen-activated protein (MAP) kinase, cell division cycle protein 2 homolog (CDC2 kinase, CDK), tyrosine kinases), and plant molecules (resveratrol, rapamycin) on the functions of ovarian cells (proliferation, apoptosis, secretory activity, expression of some protein kinases) and reproductive end points (blood level of reproductive hormones, ovarian morphology, number of ovulations, embryo yield and quality, number and viability of offspring), and their possible interrelationships and practical application in rabbit breeding are reviewed.

Transducer Mechanism: Nuclear Receptors
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:
Hormonal Regulation
Hormonal Regulation
Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...
