ABSTRACT:
A polynucleotide encoding a human vault-associated vRNA or its complementary strand. A purified and isolated polynucleotide molecule consisting essentially of a human vault RNA, or its complementary strands, or a combination of a nucleotide sequence consisting essentially of a human vault RNA and its complementary strands. A method of diagnosing a patient with a multidrug-resistant cancer. A method of treating a patient with multidrug-resistant cancer. A composition for treating multidrug-resistant cancer comprising a polynucleotide which hybridizes with a human vault-associated vRNA. A method of screening for compositions for treating a patient with multidrug-resistant cancer.
