Abstract

The aim of the present study was to understand the involved factors in follicular cysts in dairy cows. The study consisted of an in vivo and in vitro approach. The in vivo part, hormonal evaluation (Kisspeptin-10 [Kp-10], Gonadotropin inhibiting hormone [GnIH], Luteinizing hormone [LH], Oestrogens [E₂] and cortisol) was performed in sera of both healthy (H) and cows with follicular cysts (FC). The in vitro part was concentrated on estimating the distribution of GPR54 (Kp-10 receptor) and GPR147 (GnIH receptor) on cystic and preovulatory follicles. Serum concentrations of Kp-10, GnIH, LH, E₂ and cortisol were significantly higher in Group FC compared with Group H. Gene expression analysis showed a reduction in GPR54 mRNA levels in FC compared to preovulatory follicles, while no expression of the GPR147 receptor was detected. The lower presence of GPR54 in FC compared to the preovulatory follicle can be determined by a down-receptor regulation induced by elevated serum concentrations of Kp-10 in cows with ovarian FC. Endocrine imbalances of the hypothalamic-pituitary-ovarian axis, characterising FC, may reflect altered patterns of Kp-10 and GnIH secretion.

期刊介绍： The journal offers comprehensive information concerning physiology, pathology, and biotechnology of reproduction. Topical results are currently published in original papers, reviews, and short communications with particular attention to investigations on practicable techniques. Carefully selected reports, e. g. on embryo transfer and associated biotechnologies, gene transfer, and spermatology provide a link between basic research and clinical application. The journal applies to breeders, veterinarians, and biologists, and is also of interest in human medicine. Interdisciplinary cooperation is documented in the proceedings of the joint annual meetings. Fields of interest: Animal reproduction and biotechnology with special regard to investigations on applied and clinical research.
