Cell cycle–dependent uptake of putrescine and its importance in regulating cell cycle phase transition in cultured adult mouse hepatocytes
Roger L. Martin, Kenneth F. Ilett, Rodney F. Minchin – 1 December 1991 – Previous studies in which investigators have induced the rate of polyamine uptake in vitro have used either inhibitors of polyamine biosynthesis or growth factors that induce cell proliferation. Recently, however, we have described the induction of putrescine uptake in cultured adult mouse hepatocytes and have shown that uptake is independent of both intracellular polyamine levels and proliferation.
