New Gene Editing Record Made With 13200 Edits In Single Human Cell

Since its creation, CRISPR has allowed scientists to make DNA changes at specific places in a genome that can only be done once at a time. 

Now a group of researchers from Harvard University says that it has used 13,200 genetic mutation techniques in a single cell to create a new gene editing record.

Using a modified version of CRISPR, a team of genetics has successfully triggered 13,200 genetic modifications in single human cells. This is a new record, by a long shot. 

This new editing process can be used to snatch the DNA of waste or dangerous genetic information - or can create a completely new type of life.

Earlier, genre editing was done on such a large scale. In 2017, an Australian group led by Paul Thomas merged the Y chromosome of rats with the editing and was successful in hammering it with survival.

 That strategy is seen as a possible treatment for Down syndrome, which is a hereditary disorder brought by an additional chromosome.

These genetic elements, which are able to copy themselves, are estimated to have approximately 17% of our genome.

Since CRISPR cut opens double helix, so many edits together will kill a cell. This threat has restricted the previous efforts of large-scale editing.

 Geoff Faulkner of the University of Queensland in Australia said that in 2016, he tried to take out the LINE elements in 500 mouse embryos, which determines that it will affect mouse behavior. But no such rat was left to reproduce.

To prevent this problem, the Harvard team instead adopted a variation of CRISPR, known as a base editor, which avoids cutting DNA and instead alters a genetic correspondence differently, Converts a C to T.

According to his paper published in March, on the prepaid website BioRxiv, the team managed to make more than 13,000 changes together without deleting some cells simultaneously.

Faulkner says, "He found a way to experiment without generating gross genomes."

Other scientists were affected, stating that there is not a "capable" solution to enable work for genomic editing on a large scale.


The Church, however, sees large-scale editing as a way to clean the genome, in which they only remove genetic junk. 

In 2015, for example, the laboratory turned down all the 62 copies of a retrovirus which leaked within the pig's genome. 

Such viruses can be reactivated, hence making them without a pirate pig is a safety measure towards human organ transplantation.

A hardwood, laboratory from the lab, is already making pigs with the score of editing so that their limbs can be tolerated by individual transplant recipients.

As stated in the MIT Review Church, their ultimate purpose is to supply human organs or tissues, whose genomes are replaced so that they are immune to the virus.

 According to the process, which is known as the recording, according to the team, approximately 9,811 precise genetic modifications will be required. 

The church says that the laboratory has started the process of restarting the supply of their own cells in the laboratory. "It's safe to be ... and there are universal stem cells," he says.
