- Abstract
The study aimed to assess the local gene expression of adipokine members, namely vaspin, adiponectin, visfatin, resistin and their associated receptors - heat shock 70 protein 5 (HSPA5), adiponectin receptor 1 (AdipoR1) and adiponectin receptor 2 (AdipoR2) - in bovine follicles during the preovulatory period and early corpus luteum development. Follicles were collected before gonadotropin-releasing hormone (GnRH) treatment (0 h) and at 4, 10, 20, 25 and 60 h after GnRH application through transvaginal ovariectomy (n = 5 samples/group). Relative mRNA expression levels were quantified using real-time reverse transcription polymerase chain reaction (RT-qPCR). Vaspin exhibited high mRNA levels immediately 4 h after GnRH application, followed by a significant decrease. Adiponectin mRNA levels were elevated at 25 h after GnRH treatment. AdipoR2 exhibited late-stage upregulation, displaying increased expression at 20, 25 and 60 h following GnRH application. Visfatin showed upregulation at 20 h post-GnRH application. In conclusion, the observed changes in adipokine family members within preovulatory follicles, following experimentally induced ovulation, may constitute crucial components of the local mechanisms regulating final follicle growth and development., (© 2024 The Author(s).
