This study was designed to investigate the mechanism by which electric fields affect cell function,
and to determine the optimal conditions for electric field inhibition of cancer cell proliferation.
Low-intensity (<2 V/cm) and intermediate-frequency (100?300 kHz) alternating electric fields
were applied to glioblastoma cell lines. These electric fields inhibited cell proliferation by inducing
cell cycle arrest and abnormal mitosis due to the malformation of microtubules. These effects were
significantly dependent on the intensity and frequency of applied electric fields.
