Chromosomal localization of three genes coamplified in the multidrug-resistant CHRC5 Chinese hamster ovary cell line.

At least five gene classes are amplified in the multidrug-resistant CHO cell line CHRC5. Protein products have been identified for two classes; class 2 codes for the large membrane P-glycoprotein, whereas class 4 encodes the small cytoplasmic calcium-binding protein sorcin (V19). By DNA analysis we have shown previously that these five genes are linked in two groups: class 1 + 2 + 3; and class ...

Propranolol induced chromosomal aberrations in Chinese hamster ovary cell line

Propranolol (PL), a non-selective beta-blocker, is a cardiovascular drug widely used to treat hypertension. The present study was concerned with assessing the cytogenetic effects of this drug on Chinese hamster ovary (CHO) cell line. MTT assay was then carried out to determine the cytotoxicity index (IC50) of the drug. The IC50 value of PL was 0.43±0.02 mM. To investigate the clastogenic effect...

Daunorubicin-resistant Chinese hamster ovary cells expressing multidrug resistance and a cell-surface P-glycoprotein.

Independent lines of Chinese hamster ovary cells resistant to the antineoplastic drug, daunorubicin, were obtained by clonal isolation in increasing drug concentrations. A single daunorubicin-resistant phenotype typified by reduced cellular drug accumulation was observed. These mutants displayed a complex phenotype of resistance to a variety of unrelated drugs. Such properties are similar to th...

Isolation and Characterization of a Chinese Hamster Ovary Cell Line Resistant to Bifunctional Nitrogen Mustards1

A drug-resistant derivative of a Chinese hamster ovary cell line has been generated by chronic exposure to progressively higher concentra tions of chlorambucil. The cells exhibit greater than 20-fold resistance to the cytotoxic effects of chlorambucil and comparable levels of crossresistance to mechlorethamine and melphalan. These drugs all belong to a class of bifunctional alkylating agents wh...
