The expanding arena of DNA repair

Targeted gene repair -- in the arena.

The development of targeted gene repair is under way and, despite some setbacks, shows promise as an alternative form of gene therapy. This approach uses synthetic DNA molecules to activate and direct the cell's inherent DNA repair systems to correct inborn errors. The progress of this technique and its therapeutic potential are discussed in relation to the treatment of genetic diseases.

The 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...

DNA-Repair Capacity in Down\'s Syndrome

Down's syndrome (DS) is the most common chromosomal abnormality in human. Subjects with DS are known to be peridisposed to develop leukemia. The molecular basis of the association between DS and leukemia is unknown. The unscheduled DNA synthesis (UDS) test measure the ability of DNA-repair in mammalian cells after excision of a stretch of DNA containing the region of damage induced by chemical ...
