Abstract
A comparison was made of the properties of uninfected and Fujinami‐virus‐infected duck cells, uninfected and Murine Sarcoma virus‐infected rat cells, and uninfected and Rous Sarcoma virus‐infected chicken cells. It was found that alteration in cell shape, increased glycolysis in the absence of serum, and a decreased requirement of serum for multiplication and for glycolysis were constant correlates of the neoplastic conversion brought about by these RNA sarcoma viruses.
