Abstract

To explore the effect of baicalein on the proliferation and invasion of osteosarcoma cells and its related mechanism. Osteosarcoma MG-63 cells that were cultured in vitro were respectively treated with 20 μL culture medium (control group), dehydrated alcohol (0 μmol/L baicalein group), 100 and 200 μmol/L baicalein solution for 48 hours. Cell proliferation was analyzed by MTT assay. The cell invasion ability was detected using Transwell(TM) invasion assay. The expression of ezrin mRNA was examined by real-time quantitative PCR. The expressions of ezrin protein and p-ezrin protein were measured using Western blotting. Apoptosis index (AI) was determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL). The inhibitory rates of cell proliferation significantly increased in 100 and 200 μmol/L baicalein groups as compared with 0 μmol/L baicalein group. Moreover, that was higher in 200 μmol/L baicalein group than in 100 μmol/L baicalein group. In comparison with control and 0 μmol/L baicalein groups, the mean cell numbers of permeated membrane and levels of ezrin mRNA, ezrin protein and p-ezrin protein gradually decreased, but AI was gradually elevated with the increase of baicalein concentrations, wher...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
