Abstract excerpt
The human colon carcinoma cell line HT29-D4, which constitutively expresses a very low level of the MDR1 gene product, was made multidrug resistant by transfection with a human MDR1 cDNA from the pHaMDR1/A expression vector and selection by colchicine. Resistant clones were 3- to 15-fold resistant to colchicine and were cross-resistant to doxorubicin (3- to 4-fold). MDR1 gene expression was associated with the...
