Sentences with phrase «genes changing places»

Mi - Prostate Score developed from a discovery in the lab of Arul Chinnaiyan, M.D., Ph.D., in 2005 of a genetic anomaly that occurs in about half of all prostate cancers, an instance of two genes changing places and fusing together.

Not exact matches

The original change is reversed by mutations occurring at high frequency, not just reversing the engineered change — that does happen, to be sure — but causing compensatory changes that appear in many places in the knocked out gene restoring function to the gene in quite unexpected ways.

These allusions to the past aren't surprising considering how drastically the clinical trial changed gene therapy and, in particular, the career of James M. Wilson, the medical geneticist who headed Penn's Institute for Human Gene Therapy, where the test took plgene therapy and, in particular, the career of James M. Wilson, the medical geneticist who headed Penn's Institute for Human Gene Therapy, where the test took plGene Therapy, where the test took place.

The direct methylation of the DNA changes the gene expression permanently if it takes place in the control regions of genes (so - called CpG islands), that have been made accessible by the modification of the histones.

We could find out which of our modern genes were already in place, and which ones had to change to produce modern humans.

No one is arguing that Lamarck got everything right, but over the past decade it has become increasingly clear that environmental factors, such as diet or stress, can have biological consequences that are transmitted to offspring without a single change to gene sequences taking place.

As well as making history, the mice may reveal the natural biochemical changes that take place at high altitude, which could lead to a test for athletes who have had their genes manipulated.

They found that cancer cells had acquired new genetic changes that cancelled out the original errors in DNA repair — particularly in the genes BRCA2 and PALB2 — that had made the cancer susceptible to olaparib in the first place.

These changes in gene expression can help explain instances in which the yield is unaffected, but a slight reduction has taken place in the plant which scientists can not pinpoint.

And what we did is, in order to figure all this out, sort of trace the path of evolution, we did a whole bunch of sort of, swapping experiments, where we swappedGAL1 for GAL3and we swapped the ancestral protein type of protein in for GAL1or for GAL3, and we even swapped the GAL1and GAL3in for the ancestral protein, in another yeast that didn't have the duplication take place; and from this whole series of experiments, we really expected to find out pretty much how the proteins have changed; and the surprise was that most of [the] adaptive change that had taken place wasn't in the protein, it was in how the two genes were regulated.

So, I'll just say a little more about why yeast; which is, over the decades, yeast molecular biologists have devised so many powerful tools that allow you to make very precise changes in yeast, in their DNA; exquisite control, where you can change a single base that you want in a particular place, you can put a whole gene in, take a whole gene out, swap genes etc..

In a study published in the journal Cell on July 14, the researchers found that placing enhancers in different positions relative to their target genes resulted in dramatic changes in the frequency of the bursts.
