ABSTRACT
<p><b>OBJECTIVE</b>To construct the P210(T315I-BCR/ABL) transgenic mice model.</p><p><b>METHODS</b>The transgenic vector in which the P210(T315I-BCR/ABL) gene and eGFP gene was derived by APN/CD13 promoter was constructed and microinjected into the single-cell fertilized eggs of C57 mice. Transgene integration was conformed by PCR genotyping and P210(T315I-BCR/ABL) expression levels was evaluated by RT-PCR. The CML phenotype was confirmed by blood routine examination, Wright's staining for peripheral blood and bone marrow smears, HE staining for organs of transgenic mice.</p><p><b>RESULTS</b>Three transgenic mice lines with high expression of P210(T315I-BCR/ABL) gene and eGFP gene was selected. Compared with the wild type mice, the levels of WBC, platelet and neutrophil granulocyte of transgenic mice began to increase gradually at 2 months, and increase to 23.9×10⁹/L, 4 136×10⁹/L, and 74.6% respectively at 6 months. The remarkable hyperplasia of granulocytes was seen in the peripheral blood and bone marrow smears with splenomegaly infiltrated by leukemic cells.</p><p><b>CONCLUSION</b>The P210(T315I-BCR/ABL) transgenic mice was constructed and provided a model to explore the mechanism of T315I CML and screen out the drug for T315 CML patient.</p>
