Radiation Induced DNA Double-Strand Breaks in Radiology.
UNLABELLED Shortly after the discovery of X-rays, their damaging effect on biological tissues was observed. The determination of radiation exposure in diagnostic and interventional radiology is usually based on physical measurements or mathematical algorithms with standardized dose simulations. γ-H2AX immunofluorescence microscopy is a reliable and sensitive method for the quantification of rad...

متن کامل[Repair of ionizing radiation induced DNA double strand breaks].
DNA double-strand breaks (DSB) are created by ionizing radiation, an important environmental genotoxic agent. DSB are repaired by two mechanisms associated with recombination. In eukaryotic cells homologous recombination depends on genes belonging to the RAD52 epistatic group. Alternative pathway, DNA end-joining in non-homologous recombination involves DNA-dependent protein kinase (DNA-PK).
متن کاملThe Role of Long Non Coding RNAs in the Repair of DNA Double Strand Breaks
DNA double strand breaks (DSBs) are abrasions caused in both strands of the DNA duplex following exposure to both exogenous and endogenous conditions. Such abrasions have deleterious effect in cells leading to genome rearrangements and cell death. A number of repair systems including homologous recombination (HR) and non-homologous end-joining (NHEJ) have been evolved to minimize the fatal effe...
متن کاملDNA Double-Strand Breaks
The activation-induced cytidine deaminase (AID) is required for somatic hypermutation (SHM) and class-switch recombination (CSR) of immunoglobulin (Ig) genes, both of which are associated with DNA double-strand breaks (DSBs). As AID is capable of deaminating deoxy-cytidine (dC) to deoxy-uracil (dU), it might induce nicks (single strand DNA breaks) and also DNA DSBs via a U-DNA glycosylase-media...
