Glioma, which is one of the most life-threating tumors of human beings, is defined as the tumor composed with uncontrolled proliferative glial cells. For the prediction of patient prognosis and the decision of therapeutic strategy, it is important to assess proliferative activity of the glioma cells. In vivo BrdU labeling method was applied to evaluate proliferative activity of the glioma cells in 1980's. In these days, antibodies against proliferating cell nuclear antigen (PCNA) and Ki-67 (MIB-1) have been developed and routinely used for evaluating of the proliferative activity of glioma cells. Moreover, recent molecular biological studies have elucidated molecular mechanisms regulating tumor proliferation and progression. We here describe the methods assessing the proliferative activity of the tumor cells and summarize recent findings of molecular mechanisms involved in cell cycle regulation of glioma cells. Furthermore, we also describe the implication of a newly identified tumor suppressor, PTEN, in progression and proliferation of glioma cells.
