摘要

Purpose: To investigate antiproliferative and radiosensitizing effects of caffeic acid phenethyl ester (CAPE) on medulloblastoma (MB) Daoy cells. Methods and materials: Daoy cells were treated with CAPE in different concentrations and assessed for cell viability, apoptosis, cell cycles, cyclin Bl expressions, radio-sensitization and chemosensitization. Human astroglia SVGp12 cells were treated with CAPE to present the possible protection or complication effects in normal tissues. Results: CAPE inhibited the growth of Daoy cells in a time- and concentration-dependent manner in MTT and Trypan blue exclusion assays. Flow cytometry revealed that CAPE significantly decreased G2/M fraction, and increased the S phase fraction. Western blot demonstrated a down-regulated cyclin B1 protein expression. Pretreatment with CAPE markedly decreased the viability of irradiated Daoy cells. The sensitizer enhancement ratios (SERs) were increased in CAPE-treated Daoy cells. CAPE in doxorubicin and cisplatin did not show chemosensitizing effect. Conclusions: These findings demonstrate the antiproliferative and radiosensitizing effects of CAPE for Daoy cells, which might bring improvement to the treatment of MB. For clinical application, in vivo models are expected.
