Ectoine protects DNA from damage by ionizing radiation

Schröter, Maria-Astrid ; Meyer, Susann ; Hahn, Marc Benjamin ; Solomun, Tihomir ; Sturm, Heinz ; Kunte, Hans Jörg (2017-11-10)

Ectoine plays an important role in protecting biomolecules and entire cells against environmental stressors such as salinity, freezing, drying and high temperatures. Recent studies revealed that ectoine also provides effective protection for human skin cells from damage caused by UV-A radiation. These protective properties make ectoine a valuable compound and it is applied as an active ingredie...

Direct electron irradiation of DNA in a fully aqueous environment. Damage determination in combination with Monte Carlo simulations

Hahn, Marc Benjamin ; Meyer, Susann ; Schröter, Maria-Astrid ; Seitz, Harald ; Kunte, Hans-Jörg ; Solomun, Tihomir ; Sturm, Heinz (2016)

We report on a study in which plasmid DNA in water was irradiated with 30 keV electrons generated by a scanning electron microscope and passed through a 100 nm thick Si3N4 membrane. The corresponding Monte Carlo simulations suggest that the kinetic energy spectrum of the electrons throughout the water is dominated by low energy electrons (<100 eV). The DNA radiation damage, single-strand breaks...
