磁场作用于生命系统的生物物理机制尚不清楚。前期研究表明,与表皮生长因子(EGF)类似,MF暴露诱导EGF受体(EGFR)聚集并激活EGFR信号转导。在这项研究中,我们研究了MF暴露是否引起EGF的物理特性的变化以及EGF和EGFR相互作用的下游效应。相位询问表面等离子体共振(SPR)传感分析表明,在4.0 mT下50 Hz MF暴露1 h可诱导EGF溶液的可逆相对介电常数变化。然而,与假暴露的EGF溶液相比,MF暴露的EGF溶液不影响EGF与EGFR的结合,也不影响人羊膜上皮细胞(FL细胞)中的细胞活力和EGFR聚集。我们的数据表明,细胞EGFR集群反应MF曝光可能不是EGF在细胞培养液中的相对介电常数的变化的结果。生物电磁学© 2020生物电磁学学会
The biophysical mechanism of magnetic fields (MFs) acting on living systems is not clear. Previous research showed that, similar to epidermal growth factor (EGF), MF exposure induced EGF receptor (EGFR) clustering and activated EGFR signaling. In this study, we investigated whether MF exposure induced the changes in physical characteristics of EGF and downstream effects of EGF and EGFR interaction. The phase‐interrogation surface plasmon resonance (SPR) sensing analyses showed that 50 Hz MF exposure at 4.0 mT for 1 h induced reversible relative permittivity changes of EGF solution. However, compared with sham‐exposed EGF solution, the MF‐exposed EGF solution did not affect the binding of EGF to EGFR, nor the cell viability and EGFR clustering in human amniotic epithelial cells (FL cells). Our data suggest that cellular EGFR clustering response to MF exposure might not be a result of changes in relative permittivity of EGF in cell culture solution.
