31P NMR spectra of rodent and avian fibroblasts transformed by Rous or Kirsten sarcoma viruses.
31P NMR spectra of normal rodent and avian fibroblasts were compared to those of the same cells transformed either by the Rous sarcoma virus (RSV) or by the Kirsten sarcoma virus (Ki-MSV). Under physiological conditions, the spectra of living or perchloric acid extracted chicken embryo fibroblasts, rat cell line FR3T3 and mouse cell line C127 did not differ from those of their counterparts transformed by RSV or Ki-MSV. However, in the case of FR3T3 cells, on shifting from 37 degrees C to 20 degrees C, and particularly if PBS replaced serum growth medium, a different, though transitory, response of the transformed cells was detected. They then showed, within few minutes, a more rapid ATP depletion with accumulation of fructose 1,6-diphosphate (FDP), as compared to normal control cells.
