Teniposide 23-33 cyclin dependent kinase inhibitor 1A Homo sapiens 43-56 9281598-1 1997 Ionizing radiation and the topoisomerase II inhibitor, teniposide (VM-26) both increase levels of the cyclin dependent kinase inhibitor, p21(waf1/cip1) and promote dephosphorylation of the retinoblastoma tumor suppressor protein, Rb, in MCF-7 breast tumor cells, perturbations associated with suppression of the activity of the transcription factor, E2F.
