Sentences with phrase «gene repair system»
«This finding really excites us because it makes us think that this is a gene repair system that could be used to treat a range of diseases — not just tyrosinemia but others as well,» says Daniel Anderson, associate professor in MIT's Department of Chemical Engineering and a member of MIT's Koch Institute for Integrative Cancer Research and Institute for Medical Engineering and Science (IMES).

Researchers engineered a virus to carry a replacement gene to repair the immune systems of the sick children.
They programmed the new CRISPR / Cas9 system to snip out the dysfunctional exon, leaving the body's natural repair system to stitch the remaining gene back together to create a shortened — but functional — version of the gene.
In the current work, they used a new variation of the gene - editing system to repair the defect in both a mouse model and in human cells.
In the latest experiments the Mitalipov group focused on snipping out the mutated gene in heterozygous cells — a situation in which there was still a «good» nonmutated copy available for the natural cellular repair systems in the embryo to use as a template for repair after the researchers edited out the problematic one.
With her HHMI money, she will explore the connections between the immune system and circadian clock genes, as well as the link between immune response and DNA repair genes.
Field reports suggest that not all K13 mutations are capable of causing resistance, and the genetic system developed by Dr. Fidock to study K13, based on DNA repair approaches that are being used in human gene therapy studies, will be critical in identifying real hot spots of resistance.
But, fascinating anecdotes aside, does hard evidence exist of specific vulnerability genes or how they might impair the immune system, brain, and gut — and most important, do we have any rational, reliable approaches to help repair the damage?
The mfd gene was cloned and sequenced and the Mfd protein was purified and used to reconstitute strand - specific repair in a completely defined system.
However, at least 16 % or more can not be analyzed with these methods because individuals have a mutation in another mismatch repair gene, PMS2 (PMS 1 homolog 2, mismatch repair system component).
Contact: 508-685-3525; [email protected] Woods Hole, Mass. — Many of the genes involved in natural repair of the injured spinal cord of the lamprey are also active in the repair of the peripheral nervous system in mammals, according to a study by a collaborative group of scientists at the Marine Biological Laboratory (MBL) and other institutions.
PER2: Deletion of the PER2 gene in mice, associated with the mechanisms of circadian rhythm, appears to improve DNA repair in stem cell populations relevant to the immune system, resulting in a healhier immune cell population, better immune function in old age, and a modestly extended life span.
Over time, the repair system in the cell works worse, and much of this damage either is not corrected at all, disrupting the expression of genes, or converted into mutations.
The Yale team found more than 580 different genes that may play a role in regeneration of axons in nerve cells, something that rarely occurs in adult mammals but is of vital interest to scientists hoping to repair injuries to the central nervous system.
