Objective:To explore the influence of arsenic trioxide on cell cycle
cyclin and cyclin-dependent kinase inhibitor(CDKI) of human renal cell carcinoma 786-0 cells.Methods:The change of cell cycle was measured by flow cytometric assay(FCM)
and its mechanism was analyzed by immunocytochemistry and reverse transcription polymerase chain reaction. Results: Treatment with As2O3 of 2μmol/L or 5μmol/L for 24h
48h and 72h
notably induced a G2/M and G0/G1 cell cycle arrest in 786-0 cells
decreased expression of cyclin A
B1
D1
E(P<0.05) and increased expressions of CDKI genes p16
P21WAF1/CIPI and p27kip1(P<0.01).Conclusions:As2O3 can inhibit the growth in 786-0 cells effectively by down-regulating expression of cyclinA
