Abstract
Genomic and cDNA clones of human genes which are selectively amplified or overexpressed in multidrug-resistant human tumor cells were isolated. Such clones may be used as probes in diagnostic tests to detect chemotherapy-resistant tumor cells and to predict tumor response to chemotherapy. The complete nucleotide sequence of the coding region of the human mdr1 gene and the complete corresponding amino acid sequence are disclosed.
Claims8
An isolated nucleic acid of the human mdr1 or mdr2 gene, or the complement thereof, selected from the group consisting of:
- a) a polynucleotide comprising a continuous sequence of nucleotides as set forth in FIG. 4 or the RNA equivalent thereof;
