Expression pattern of FoxN1 gene and response to low temperature in Min pig / 中国兽医学报

ABSTRACT

Thymus is an important immune organ in mammals.FoxN1 plays an important role in regulating the development of thymic epithelial cells.Pig is a domestic animal of meat type,and is also a new kind of experimental animal model.In order to better understand the development characteristics of pig own immunity,the expression pattern of Minzhu FoxN1 in 2 month,4 month,6 month and 8 month thymus were detected by real-time PCR and Western-blot.At the same time,the changes of FoxN1 expression in Minzhu and Large white pig after cold stress were also detected.The results showed that FoxN1 expression level reached the highest level in 4 month,and declined in 6 month.This expression pattern is consistent with human and mouse.Cold stress could rise the expression level of Minzhu FoxN1,while have no effect on the Large white pig.
