Using cultured V79 Chinese hamster cells, we found that novobiocin (or 2,4-dinitrophenol) can abrogate, almost completely, the cytotoxicity due to the topoisomerase II inhibitor amsacrine (mAMSA). V79 cells were sensitive to mAMSA killing at all stages in the cell cycle but mainly in S phase followed by late GI phase; however, novo rescued cells of all ages. The properties of two kinds of radia...

An outbreak of goatpox was attended in district Durg and surrounding regions of Chhattisgarh state. Dried skin scabs were collected from 250 goats of different age groups showing clinical signs suggestive of pox. The prevalence rate was studied based on severity of clinical signs followed by confirmation with agar gel immuno diffusion (AGID) test. Positive scabs were further processed for virus...

The mechanism by which pertussis toxin induces morphological changes in Chinese hamster ovary cells was studied to determine whether the resulting clustered growth pattern is due to toxin-catalyzed ADP-ribosylation of a cellular substrate. While pertussis toxin was extremely potent in inducing morphological changes in Chinese hamster ovary cells, preparations of isolated A subunit or B oligomer...

The Chinese Hamster ovary (CHO) cell line is widely used for measuring drug cytotoxicity and resistance. Therefore, the effects of two major Ayurvedic drugs (W. somnifera root and E. officinalis fruits) on the short and long-term growth of these cells were investigated. A standard 96-well plate assay was used to measure short-term growth. For assessment of long-term growth, the colony formation...

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...

The effect of glucose deprivation on the synthesis of lipid-linked oligosaccharides by Chinese hamster ovary cells has been studied. When these cells are placed in serum-free Dulbecco's minimal essential medium devoid of glucose, there is a rapid cessation of the synthesis of the usual Glc3Man9GlcNAc2 lipid-linked oligosaccharide and the accumulation of a smaller species with the composition Ma...

Chinese hamster ovary cells show endogenous high-affinity Na(+)-dependent glutamate transport activity. This transport activity is kinetically similar to a glutamate transporter family strategically expressed in the central nervous system and is pharmacologically unlike glutamate transporter-1 or excitatory amino acid carrier 1. The cDNA of a glutamate/aspartate transporter (GLAST)-like transpo...

Several antimitotic, tubulin-binding agents, such as colchicine, colcemid, and podophyllotoxin, inhibit the capping of fluorescent-labeled concanavalin A in Chinese hamster ovary cells. By comparing the effects of these agents on parental cell lines on several independently selected colchicine-resistant mutants with decreased drug permeability, we have demonstrated that permeation of these drug...
