In order to increase the expression of mdrl genetransfectcd using retroviral vcctors, we constructedtwo retroviral vectors (LmdrlSN and MSCV-mdrl)containing mdrl cDNA and compared the expressionof mdrl gene with another vector pHamdrl/A(Pastan et al. Proc Natl Acad Sci USA 85: 4486,1986) in NIH.3T3 cells. The LmdrlSN was made by
