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...

متن کاملIncreased antibody productivity in Chinese Hamster Ovary cells through induction of chromosomal instability by cell fusion
Background Chromosomal instability, which often occurs as a random event in an uncontrollable manner, is a key characteristic of Chinese Hamster Ovary (CHO) cells. This often complicates the process of establishing stable, high antibody-producing CHO cell lines. We previously found that the abnormal increase of chromosome number is linked to increased antibody production in adherent CHO DG44 ce...
متن کاملChromosomal 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 ...
متن کاملChinese hamster ovary cell culture
The effect of 26-hydroxycholesteroI and other intermediates in bile acid synthesis on HMG-CoA reductase activity was studied in Chinese hamster ovary (CHO) cell culture. Incubation of CHO cells for 5 hr in 0.25 PM 26-hydroxycholesterol caused a 40% inhibition of HMG-CoA reductase activity. All other intermediates tested including 3B-hydroxy-5cholenoic acid and cholest-5-ene-3B,7a,26-triol, oxid...
