Gt(ROSA)26Sor^{em55(Vil1-CYP3A4,-tdTomato)Smoc}

Intestinal expression of the CYP3A enzyme in the human body can cause significant intestinal metabolism of the compound, resulting in impaired drug absorption. This knock-in model was generated by inserting the human CYP3A4 cDNA driven by the Villin1 promoter together with the IRES-tdTomato reporter gene into mosue Rosa26 site, which can be crossed with the Cyp3a13 gene knockout and other Cyp3a family genes knockout mice to obtain intestinal-expressed CYP3A4 Humanized sequence mouse model in order to determine the contribution of intestinal metabolism to the absorption and distribution of test article.
