Electric field induced DNA damage: an open door for selective mutations.
نویسندگان
چکیده
Intense electric fields activate the mutagenic mechanism of a single guanine-cytosine base pair. Would they be able to induce a permanent mutation in real DNA? This question is addressed here by modeling a DNA-embedded fragment with state-of-the-art theoretical tools. We show how DNA can, in principle, be mutated if an appropriate electric field is applied.

Objective: The discovery and development of natural products with potent antioxidant properties has been one of the most interesting and promising approaches in the search for treatment of CNS injuries. The most significant consequence of the oxidative stress is thought to be the DNA modifications, which can become permanent via the formation of mutations and other types of genomic instability ...
متن کاملStudy of leaky dielectric droplet behavior under an electric field: effect of viscosity and electric conductivity ratios
In this research, hydrodynamic behavior of a leaky dielectric droplet under an electric field is simulated. The level set method is used for interface tracking and the ghost fluid method is used for modeling discontinuous quantities at interface. Using Taylor’s leaky dielectric model, electric field and electric force at the interface is calculated. Simulation results show the droplet deformati...

Abstract – In this paper, the effect of applied electric field on the damage due to partial discharges activity into the surroundings dielectrics of a narrow channel encapsulated within the volume of a dielectric material is evaluated using a kinetic model based on Particle in Cell - Monte Carlo Collision (PIC-MCC) model. After application of an electric field across a dielectric material which...
متن کاملExposing the G-quadruplex to electric fields: the role played by telomeres in the propagation of DNA errors.
To protect their core machinery from the attack of exogenous agents, cells locate DNA in their nucleus. Nevertheless, some reactive chemical species and physical agents might reach DNA and alter its natural double helix structure. For instance, pulsed electric fields can be used to selectively rewrite the stored genetic information. However, for such modification to be effective, one needs, as ...
