Drugs that selectively attack dividing cells are often used in cancer therapy. However, small cell populations do not die, but develop resistance to a variety of toxic drugs. Multidrug resistance is achieved by gene amplification of specific membrane-bound transport ATPases that shuttle the drugs out of cells. Some multidrug-resistant cancer cells express a protein of 110 kDa named LRP (Lung Resistance-related Protein). LRP expression might be an indicator of prognosis after chemotherapy in acute myeloid leukemia and ovarian carcinoma. The LRP gene encodes a protein of 896 amino acids with significant homology to the major vault protein from Dictyostelium discoideum. Although ubiquitously expressed, LRP is most abundant in epithelial cells.
