Adrenal corticosteroids enhance production of type-C virus induced by 5-iodo-2'-deoxyuridine from cultured mouse fibroblasts.

چکیده
Induction of RNA "tumor" viruses by 5-iodo-2'-deoxyuridine in mouse fibroblasts is stimulated 5- to 25-fold by glucogenic adrenal corticosteroids. Enhancement of virus production by the hormones is inhibited by low concentration of cordycepin, an inhibitor of poly(A) synthesis.

Effect of caffeine on induction of endogenous type C virus in mouse cells in vitro.
The effect of caffeine on the expression of murine endogenous virus in mouse cells induced by radiation and chemicals was studied. Postirradiation treatment of K-BALB cells with caffeine enhanced cell killing as well as the induction of xenotropic virus after ultraviolet light irradiation. The degree of enhancement for the virus induction was comparable to that for cell killing. On the other ha...

متن کاملOncogenic transformation of C3H/10T1/2 clone 8 mouse embryo cells by halogenated pyrimidine nucleosides.
Oncogenic transformation has been induced in vitro in the C3H/10T1/2 clone 8 line of mouse cells by exposure to 5-fluoro-2'-deoxyuridine (FUdR) or 5-fluorouracil. This transformation is both dose and time dependent and can be markedly decreased by simultaneous exposure of the cells to thymidine. The transformation induced by 5-fluorouracil is probably due to its intracellular conversion to FUdR...
متن کاملEvaluation of mixed cell types and 5-iodo-2'-deoxyuridine treatment upon plaque assay titers of human enteric viruses.
Four continuous cell lines, BGM, L-132, HEL-299, and RD, were compared both when cultured separately and as mixtures for use in plaque assay titrations of human adenovirus 1 and six human enterovirus serotypes. The effect of incubating these cell cultures in media containing 5-iodo-2'deoxyuridine (IDU) prior to inoculation with virus was also studied. The use of mixed-cell cultures revealed cel...
متن کاملEffect of cytosine arabinoside and 5-iodo-2'-deoxyuridine on a cytomegalovirus infection in newborn mice.
Murine cytomegalovirus was inhibited by 0.6 to 1.2 mug of cytosine arabinoside per ml and by 0.3 to 0.6 mug of 5-iodo-2'-deoxyuridine in mouse embryo fibroblast cells. Human cytomegalovirus was inhibited by similar concentrations of the two drugs in WI-38 cells. Intraperitoneal inoculation of suckling mice with 10(4.5) plaque-forming units of murine cytomegalovirus provides a model for dissemin...
