Effect of Exposure to Ionizing Radiation on Biomarker of Oxidative Damage of DNA

Introduction: one of the most important complications of exposure to ionizing radiation is emergence of cancer tumors, which happens as a result of oxidative DNA.  Therefore, the present study was conducted, aimed to measuring 8-DIHYDROxy- 2’- DEOXYGUANOSINE (8-OHdG) level in radiographers’ urine as oxidative damage biomarker, as well as comparing this biomarker with cumulative effective doses....

Immunological reaction of UV-induced radiation damage in coliphage DNA.

Denatured DNA of coliphage T1, poly-dT and dTpT were UV-irradiated (2537 A) and conjugated to methylated bovine serum albumin. These molecules act as haptens after injection into rabbits. Antibodies are predominantly formed against UV-induced cyclobutane-type of cis-synthymine dimers. They belong to the IgG-type of antibody molecules. Antigen-antibody complexes were detected by means of the CsC...

Reduced DNA damage in tumor spheroids compared to monolayer cultures exposed to ionizing radiation

Background: Several cell lines when cultured under proper condition can form three dimensional structures called multicellular tumor spheroids. Tumor spheroids are valuable in vitro models for studying physical and biological behavior of real tumors. A number of previous studies using a variety of techniques have shown no relationship between radiosensitivity and DNA strand breaks in monolayer ...
