Inhibin A regulates follicular development via hormone secretion and granulosa cell behaviors in laying hens

Inhibin A regulates follicular development, and its expression level is related to physiological activities, such as the recruitment, selection, and predominance during follicular development. Therefore, examining inhibin A and its regulatory effects on the reproductive performance of poultry is cru...

Description
Summary:Inhibin A regulates follicular development, and its expression level is related to physiological activities, such as the recruitment, selection, and predominance during follicular development. Therefore, examining inhibin A and its regulatory effects on the reproductive performance of poultry is crucial. In this study, we measured the mRNA and protein abundances of INHA and INHBA in the chicken reproductive system and determined the hormone secretion and apoptosis of follicular granulosa cells (GCs) after being treated with inhibin A protein, and flow cytometry was performed to analyze GC apoptosis in INHA -specific small RNA interference (siRNA). We detected that INHA and INHBA were mainly expressed in chicken follicles. The highest INHA mRNA abundance was found in the fifth largest preovulatory follicle (F5) ( P
