Aim To explore the possible role of p21, cyclin E and cyclin-dependent kinase 2 (CDK2) in the protection of ginsenoside Rgl against tert-butylhydroperoxide (t-BHP)-induced senescence in WI-38 cells.

• 目的 探讨p21、细胞周期蛋白E(cyclin E)和周期蛋白依赖性蛋白激酶2(cyclin-dependent kinase 2,CDK2)在人参皂苷Rgl对抗三丁基过氧化氢(t-BHP)诱导’WI-38细胞衰老过程中的可能作用。
