Functional analysis of the VNTRs within ABL1-MS1 in luciferase reporter vector promoter region. a ABL1 promoter vector (p2000) and four promoter vectors in which four different lengths of ABL1-MS1 (TR13–TR16) were inserted were used. The ABL1 promoter region is indicated by diagonal squares, and the luciferase gene is indicated by gray squares. Four different lengths of ABL1-MS1 were inserted after the luciferase gene and are indicated by black squares. b The above five different types of promoter vectors were transfected into 293 T and UC3 cells. ABL1 promoter activity was measured by luciferase assay
