Early manifestation of hypophosphatemic rickets in goslings: a potential role of insufficient muscular adenosine triphosphate in motility impairment of early P-deficient geese Poul. Sci. (IF 4.4) Pub Date : 2024-04-04 Lei Xu, Ning Li, Dongzhi Miao, Chunhui Huang, Lei Chen, Haiming Yang, Zhiyue Wang
We aimed to determine the onset time of hypophosphatemic rickets and investigate the mechanism of motility impairment through adenosine triphosphate () production in goslings. Two hundred and sixteen 1-day-old male Jiangnan white geese were randomly divided into 3 groups, with 6 replicates and 12 geese per replicate. Birds were fed on 3 diets: a control diet (nonphytic phosphorus, NPP, 0.38%), a P-deficient

The effect of LINC9137 targeting miR-140-3p-NKAIN3 signal axis on the development of goose testis sertoli cells Poul. Sci. (IF 4.4) Pub Date : 2024-04-04 Wu Yingping, Lu Lizhi, Li Haiying, Chen Li, Gu Tiantian, Zhao Xiaoyu, Yao Yingying, Li Jiahui
Sertoli cells () are a type of important cells in the testes, which can provide transport proteins, regulatory proteins, growth factors, and other cytokines for the spermatogenic process. They participate in the regulation of the maturation and differentiation of spermatogenic cells and play an important supporting role in the migration, proliferation, and differentiation of germ cells at all levels

An in vitro validation system for chicken bioreactors using immortalized chicken oviductal epithelial cells Poul. Sci. (IF 4.4) Pub Date : 2024-04-04 Kyung Min Jung, Eunhui Yoo, Jae Yong Han
The utilization of chicken oviductal epithelial cells () as a bioreactor to produce therapeutic proteins has shown promise, but the time taken to obtain transgenic offspring impedes efficient validation of protein production. To overcome this barrier, we focused on the immortalization of chicken OECs () using retroviral vector-mediated oncogene expression to establish an in vitro pre-validation system

Gliotoxin elicits immunotoxicity in the early innate immune system of ducks Poul. Sci. (IF 4.4) Pub Date : 2024-04-04 Zhengkai Wei, Qinqin Jin, Wei Liu, Tingting Liu, Kaifeng He, Zha Jin, Meiyi Chen, Yuqian Jiang, Yuxiao Qian, Hongrong Hong, Dezhi Zhang, Quan Liu, Zhengtao Yang, Qianyong Li
Gliotoxin () belongs to the epipolythiodioxopiperazine () family, which is considered a crucial virulence determinant among the secondary metabolites produced by . The metabolites are commonly found in food and feed, contributing to the invasion and immune escape of , thereby posing a significant threat to the health of livestock, poultry, and humans. Heterophil extracellular traps (), a novel form

Occurrence, virulence, and resistance genes in Salmonella enterica isolated from an integrated poultry company in Jordan Poul. Sci. (IF 4.4) Pub Date : 2024-04-04 Mohammad H. Gharaibeh, Shawkat Q. Lafi, Ahmed M. Habib Allah, Farah R. Al Qudsi
is considered one of the most common foodborne pathogens worldwide. The annual number of hospitalizations and deaths related to zoonotic salmonellosis, which is transmitted from animals to humans and infects poultry and meat, is expected to be significant. Hence, the primary aims of this research were to isolate and characterize species obtained from an integrated poultry company and identify some

Melatonin alleviates endoplasmic reticulum stress to improve ovarian function by regulating the mTOR pathway in aged laying hens Poul. Sci. (IF 4.4) Pub Date : 2024-04-04 Er-ying Hao, Xue-lu Liu, Li-yun Chang, Han Xue, Bo-fei Su, Yi-fan Chen, De-he Wang, Lei Shi, Hui Chen
Granular cell apoptosis is a key factor leading to follicular atresia and decreased laying rate in aged laying hens. Endoplasmic reticulum stress () induced cell apoptosis is a new type of apoptosis pathway. Previous studies have shown that the ERS pathway is involved in the regulation of follicular development and atresia, and can be regulated by mTOR. Melatonin () can protect the normal development

Pyrococcus furiosus argonaute combined with loop-mediated isothermal amplification for rapid, ultrasensitive, and visual detection of fowl adenovirus serotype 4 Poul. Sci. (IF 4.4) Pub Date : 2024-04-03 Zhaorong Yu, Daoming Shi, Yanli Dong, Ying Shao, Zhe Chen, Fanyu Cheng, Yu Zhang, Zhenyu Wang, Jian Tu, Xiangjun Song
Since 2015, an outbreak of an infectious disease in broilers caused by fowl adenovirus serotype 4 () has occurred in China, resulting in substantial economic losses. Rapid, accurate, and specific detection are significant in the prevention and control of FAdV-4. In this study, an FAdV-4 detection method combining loop-mediated isothermal amplification () and Argonaute () was established. Specific primers
