Atractylenolide-II inhibits proliferation and migration of glioblastoma cells

ABSTRACT:     Glioblastoma (GBM) is the most malignant and lethal brain tumor in adults, with limited therapeutic options and dismal prognosis. Atractylenolide-II (AT-II) is a major bioactive compound from Atractylodes macrocephala Koidz. (Baizhu in Chinese), with anti-inflammatory and anti-tumor activities. However, the anti-tumor effects of AT-II on GBM cells remain unclear. In the present study, the cytotoxicity of AT-II on GBM cells was analyzed using CCK-8 assay, and it revealed that the cell viability was inhibited by AT-II in a dose-dependent manner. The results of Transwell migration assay indicated that AT-II treatment significantly inhibited the cell migration. Furthermore, the cell cycle arrest at G0/G1 phase in AT-II treated cells was presented in the flow cytometry data. Consistently, real-time PCR and western blotting revealed a remarkable decrease of the CCNA and CCNB expression upon AT-II treatment. Moreover, the phosphorylation of both extracellular signal-regulated kinase (ERK) and p38 mitogen-activated protein kinase (MAPK) was triggered by AT-II. Collectively, these results suggested that MAPK signaling was involved in AT-II induced cell cycle arrest, contributing to the inhibition of cell viability and migration of GBM cells.
