Abstract

Egg production, an important economic trait in the poultry industry, is sensitive to heat stress. The hypothalamus is a crucial center for thermoregulation by detecting temperature changes and regulating the autonomic nervous system in poultry. Baihu decoction (BH), which contains four ingredients (Rhizoma Anemarrhenae, Gypsum Fibrosum, Radix Glycyrrhizae, and Semen Oryzae Nonglutinosae), is a traditional Chinese medicinal formula for clearing heat. Our study aimed to investigate the changes in gene transcription levels in the hypothalamus of laying hens treated with heat stress with and without BH using RNA sequencing. A total of 223 differentially expressed genes (DEGs) were identified in the heat-treated group compared with the control group and 613 DEGs were identified in the BH group compared with the heat-treated group. Heat shock led to significant changes in the expression of multiple genes involved in the "neuroactive ligand-receptor interaction" pathway. Moreover, feeding BH led to significant upregulation in the expression of eight genes encoding heat shock proteins (HSPs), which were highlighted as candidates to control the "protein processing in the endoplasmic reticulum (ER)" pathway. These results provide the novel insight that BH responds to heat stress by participating in regulation of the ER signaling pathway and HSPs expression.

rna测序揭示白虎汤对热休克条件下蛋鸡差异表达基因的影响
蛋产量是家禽业的一项重要经济性状,对热应激非常敏感。下丘脑是一个重要的体温调节中心,通过检测温度变化和调节自主神经系统。白虎汤(BH)是一种清热中药方剂,含有四种成分(海参、纤维石膏、甘草、米精)。本研究旨在利用RNA测序技术研究热应激条件下蛋鸡下丘脑基因转录水平的变化。与对照组相比,热处理组共鉴定出223个差异表达基因(DEGs),与热处理组相比,BH组共鉴定出613个差异表达基因(DEGs)。热休克导致参与“神经活性配体-受体相互作用”通路的多个基因表达发生显著变化。此外,喂养BH导致编码热休克蛋白(HSPs)的8个基因的表达显著上调,这些基因被强调为控制“内质网(ER)蛋白加工”途径的候选基因。这些结果提供了新的见解,即BH通过参与内质网信号通路和热休克蛋白表达的调节来响应热应激。
