Abstract:
Objective:To build the model of the gene FKBP38 (FK506 binding protein 38) conditional knock out in liver.Methods:Transgenic mouse whose FKBP38 gene was flanked with loxP was constructed by embryo microinjection.The FKBP38 gene was deleted by breeding mice harboring two loxP sites in FKBP38 (FKBP38fl/fl) with the mice bearing the expression ofCre recombinase mice driven by an album promoter.Afterward,the genotype of FKBP38 conditional knockout mice was analyzed.Results:①Relative hepatic FKBP38 mRNA levels showed significant difference between FKBP38 conditional knockout mice (FKBP38-/-) and wild type(P＜ 0.001).②Relative hepatic FKBP38 protein expression levels of FKBP38 conditional knockout mice (FKBP38-/-) were significantly different with wild type(P＜0.001).③Relative phosphorylation of hepatic p70 S6K and 4E-BP-1 protein of FKBP38 conditional knockout mice (FKBP38-/-) showed no significant difference,with slight decrease in phosphorylation of 4E-BP-1,compared with wild type.④No significant difference in expression of hepatic Bcl-2 between FKBP38-/-and wild type.Conclusions:The mouse model of the gene FKBP38 (FK506 binding protein 38) conditional knock out in liver is successfully built.
