متن کاملPeroxisome-deficient Chinese hamster ovary cells with point mutations in peroxisome assembly factor-1.
Chinese hamster ovary (CHO) mutant cells deficient in peroxisome biogenesis regain peroxisomes after transfection with a cDNA coding for peroxisome assembly factor (PAF)-1 from rat liver. Reconstitution of the transfected mutant cells with wild-type cytoplasm was not required, demonstrating that expression of the PAF-1 gene alone was sufficient for the restoration of peroxisome biogenesis. Plas...
متن کاملPropranolol 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 کاملAdhesion of glycosaminoglycan-deficient chinese hamster ovary cell mutants to fibronectin substrata
We have examined the role of cell surface glycosaminoglycans in fibronectin-mediated cell adhesion by analyzing the adhesive properties of Chinese hamster ovary cell mutants deficient in glycosaminoglycans. The results of our study suggest that the absence of glycosaminoglycans does not affect the initial attachment and subsequent spreading of these cells on substrata composed of intact fibrone...
متن کاملIsolation of Chinese hamster ovary cell mutants deficient in excision repair and mitomycin C bioactivation.
Mitomycin C (MMC), a bifunctional alkylating agent, requires metabolic reduction to become biologically active. We have identified a series of genetically related Chinese hamster ovary cell lines which span approximately three orders of magnitude in the concentration of MMC required for cell killing. Many mechanisms, including drug transport, drug activation, drug detoxification, and the elimin...
