title: Synthesis of the nuclear protein cyclin in growing, senescent and morphologically transformed human skin fibroblasts.
abstract: Quantitative two-dimensional gel electrophoretic analysis (IEF) of the nuclear polypeptide cyclin in normal human skin biopsies, growing and senescent fibroblasts and morphologically transformed skin fibroblasts (limited life span) has revealed a direct correlation between the levels of this protein and proliferative state of the cells. These results strengthen the notion that cyclin may be a key component of the pathway(s) that control cell proliferation.
