The effects of external electric fields of 900 MHz and 2450 MHz frequencies on αβ-tubulin dimer stabilized by paclitaxel: Molecular dynamics approach

Abstract

Using molecular dynamics simulation method, the effects of external electric fields of 900MHz and 2450 frequencies on αβ-tubulin dimer stabilized by paclitaxel, have been modeled. Due to this purpose, two systems, (A) αβ-tubulin dimer and (B) αβ-tubulin dimer stabilized by paclitaxel, were exposed to an external electric field of 0.01V/nm with frequency values of 900MHz and 2450MHz. It was found that application of these fields, which are in the range of cell phone and microwave frequencies, increased the flexibility of each system. Since paclitaxel, as chemotherapy drug, is used to increase the rigidity of dimer, application of such fields may disturb the effect of paclitaxel on the dimer. Consequently, negative side effects on the chemotherapy process may be observed. © 2016 World Scientific Publishing Company.
