Characterization of human tracheal epithelial cells transformed by an origin-defective simian virus 40.
To facilitate understanding of the mechanisms underlying pulmonary diseases, including lung cancer and cystic fibrosis, we have transformed and characterized cultures of human tracheal epithelial cells. Cells were transfected by calcium phosphate precipitation with a plasmid containing a replication-defective simian virus 40 (SV40) genome. Colonies of cells with enhanced growth potential were i...
متن کاملSelective killing of simian virus 40-transformed human fibroblasts by parvovirus H-1.
A normal strain of human foreskin fibroblasts, two SV40-transformed derivatives with finite and infinite life spans, and an established line of SV40-transformed newborn human kidney cells are compared for their susceptibility to infection with parvovirus H-1. H-1 inocula, which do not detectably alter the growth of normal cells, cause a progressive degeneration of all three SV40-transformed cul...
متن کاملProperties of simian virus 40 rescued from cell lines transformed by ultraviolet-irradiated simian virus 40.
Simian virus 40 (SV40) strains have been rescued from various clonal lines of mouse kidney cells that had been transformed by ultraviolet (UV)-irradiated SV40. To learn whether some of the rescued SV40 strains were mutants, monkey kidney (CV-1) cells were infected with the rescued virus strains at 37 C and at 41 C. The SV40 strains studied included strains rescued from transformed cell lines cl...
متن کاملSimian virus 40-transformed human cells that express large T antigens defective for viral DNA replication.
Many types of human cells cultured in vitro are generally semipermissive for simian virus 40 (SV40) replication. Consequently, subpopulations of stably transformed human cells often carry free viral DNA, which is presumed to arise via spontaneous excision from an integrated DNA template. Stably transformed human cell lines that do not have detectable free DNA are therefore likely to harbor harb...
متن کاملSuperinfection of simian virus 40-transformed permissive cells with simian virus 40.
Evidence that the resistance of simian virus (SV40)-transformed permissive cells to superinfection with SV40 is due to lack of virus uptake is presented. When virus uptake is enhanced, the events of infection proceed as in normal permissive cells, resulting in production of infectious virus.
