Integrated transcriptomic hypothalamic-pituitary-ovarian axis network analysis reveals the role of energy availability on egg production in layers by Jianling Peng, Yong Cui, Haiping Liang, Shenyijun Xu, Linjian Weng, Meng Ru, Ramlat Ali, Qing Wei, Jiming Ruan, Jianzhen Huang

“…Consequently, this suppression of the hypothalamus and pituitary affected ovarian function through ovarian steroidogenesis and the extracellular matrix (ECM)-receptor interaction. These findings suggest that energy deprivation inhibits the function of the HPO axis, leading to impaired follicle development and reduced egg production, and that refeeding can partially restore these indicators.…”
