title: Effect of peptichemio exposure on DNA synthesis in a mammalian cell system in vitro.
abstract: The effect of Peptichemio (PTC) on the survival and DNA synthesis in mouse L-cells was studied. Experimental data show that a typical dose-survival curve is obtained when L-cells are cultivated in the presence of PTC. Exposure of L-cells to various concentrations of PTC caused an inhibition in cellular ability to synthesize DNA which is evidenced by the decreased incorporation of 3H-thymidine. This inhibition is dependent on the concentration of PTC and the time of exposure.
