The effect of the DNA-suppressing factor (DSF) on host DNA synthesis in synchronized cell cultures. 1977

T Minagawa, and N Fujii, and T K Yamamoto, and H Iida

Purified host DNA-suppressing factor (DSF) produced into culture fluid of HeLa C-9 cells infected with measles virus inhibited cellular DNA synthesis in HeLa cells. When purified DSF was added into cultures of synchronous HeLa cells at the early G1-phase, cellular DNA synthesis was irreversibly inhibited. However, DSF did not affect the stability of native double-stranded DNA nor the chain-elongation of single-stranded DNA in cells of the S-phase.
