The nature of multiple plastomes allows for highly efficient gene conversion in asexual genetic systems, correcting mutations and reducing the mutational load of plastomes (Khakhlova and Bock 2006).
"There is increasing interest in manipulating the genome of T-cells, either by correcting mutations or changing the genome to increase the chances of the cells being able to fight off cancer or infections," Dr Marson said.
Despite the high incidence of revertant mosaicism (35%) in patients with the genetic skin disease epidermolysis bullosa (EB) due to correcting mutations in the genes COL17A1 and LAMB3, revertant mosaicism has not been described for COL7A1 until recently.
Another key advantage of hiPSCs over the current transplantation approaches is the possibility of correcting mutations by homologous recombination technology.
Moreover we have established a new, corrected mutation rate necessary for quasispecies formation with a higher value than the original one.
Finally, this recent story, again by Ian Sample, is about a fascinating scientific advance that has allowed researchers to edit the genome of living animals (mice in this case) to correct mutations that cause an inherited blood disorder.
In laboratory studies, scientists have used genome editing – known technically as Crispr-Cas9 – to correct mutations that cause metabolic disorders, to create cells that attack tumours and to make others that are resistant to HIV infection.
Researchers in the US used a powerful new gene-editing procedure called CRISPR to correct mutations in the dystrophin gene in mice that were destined to develop the disease.
Genome engineering is an emerging strategy to treat monogenic diseases that relies on the use of engineered nucleases to correct mutations at the nucleotide level.
He and others have recently used gene-editing tools to correct mutations in human iPS cells but haven't used the same combination of methods or done the same set of experiments to determine whether the iPS-derived cells are safe.
