Abstract
Abstract A clone of HeLa cells has been selected in the presence of 5-methylnicotinamide. In the presence of 10 mM 5-methylnicotinamide the resistant cells grow at 70% of the rate of the same cell culture without 5-methylnicotinamide. 10 mM 5-methylnicotinamide completely inhibits the growth of normal HeLa cells. Both cell types in the absence of 5-methylnicotinamide have the same generation time. Poly (adenosine diphosphate-ribose) synthesis is less sensitive to 5-methylnicotinamide in nuclei isolated from the resistant cells than in nuclei from sensitive cells.
