摘要

Aim: The aim of this study was to examine the effect of bisphenol A (BPA) on the proliferation and motility potential of murine LM8 osteosarcoma cells. Materials and Methods: LM8 cells were treated for 3 days with or without 80 mu M BPA. The effect of BPA on cell proliferation was determined by DNA measurement in the cultures and 5-bromo-2'-deoxyuridine (BrdU) incorporation study. Ethanol-fixed cells were stained with hematoxylin-eosin (H&E) to visualize cell morphology. Cell motility was assayed using inserts with uncoated membranes in invasion chambers. Expression of cell division cycle 42 (CDC42) was determined by immunofluorescence staining and western blotting. Results: BPA reduced the DNA content of cultures and the number of BrdU-positive cells. BPA induced a change in morphology from cuboidal with multiple filopodia on the cell surface to spindle-shaped with a smooth cell surface. BP-Atreated cells expressed less CDC42 and were less motile than untreated cells. Conclusion: BPA inhibited DNA replication and cell proliferation. BPA inhibited filopodia formation and motile potential by inhibiting CDC42 expression in LM8 cells.
