SmtDNA: A Geant4-DNA user application for evaluating radiation-induced damage in supercoiled mitochondrial DNA

Radiation track and DNA damage

Radiation-induced DNA damage responses.

The amazing feature of ionising radiation (IR) as a DNA damaging agent is the range of lesions it induces. Such lesions include base damage, single strand breaks (SSBs), double strand breaks (DSBs) of varying complexity and DNA cross links. A range of DNA damage response mechanisms operate to help maintain genomic stability in the face of such damage. Such mechanisms include pathways of DNA rep...

Evaluating the effects of galbanic acid on hydrogen peroxide-induced oxidative DNA damage in human lymphocytes

Objective: Ferula szowitsiana has been widely used for medicinal purposes around the world. The anti-oxidant effect of F.szowitsiana had been proved. The current study aims to determine the protective effects of galbanic acid, a sesquiterpene coumarin from F. szowitsiana, against hydrogen peroxide (H2O2) - induced oxidative DNA damage in human lymphocytes. Materials and Methods: Human lymphocyt...

A REPORT OF RAPID AND EFFICIENT METHOD FOR MITOCHONDRIAL DNA

Based on the similarity of prokaryotic DNA to that of mitochondrial DNA, a rapid and efficient method for DNA purification from mitochondrial extracts obtained from different sources, was carried out based on the modification method described by Marmur (1983) which resulted in a high degree of purity (A260/A280=2). In addition we have applied the same technique for the first time to purify...
