There are problems with using viruses to transfer genes
into cells," Cooke said.
To transfer genes
into cells, an inert virus is used to deliver the gene into a target cell.
Scientists have long known that bacteria--most of which reproduce by splitting rather than sex--are also able to transfer genes
from one to another through something called "horizontal gene transfer.
They can change at will, are almost indestructible and can transfer genes
from creature to creature.
Therefore] no conceptual distinction exists between genetic modification of plants and microorganisms by classical methods or by molecular techniques that modify DNA and transfer genes
For a long time, reprogramming efforts were based on four separate viruses to transfer genes
into the cells' DNA - one virus for each reprogramming gene (Oct4, Sox2, c-Myc and Klf4).
Attempts to demonstrate plasmids or transfer genes
encoding TEM-1 or PER-1 failed (data not shown), which suggests that the genes were chromosomally encoded.
teamed with researchers at Purdue University in a two-year study funded by the National Institute of Health (NIH) to transfer genes
involved in the metabolism of selenium, a mineral known to aid in cancer prevention, into edible plants.
The project aims to identify and transfer genes
for essential omega-3 oil (fatty acid) production, from marine microalgae to oilseed plants such as canola or linseed.
The possibility to either transfer genes
into human cells or modulate endogenous gene expression has led to novel and revolutionary therapeutic opportunities, especially for single-gene disorders such as hemoglobinopathies (6, 7).
Agrobacterium was also found to transfer genes
into several types of human cells (18), and in a manner similar to that which it uses to transform plant cells.
But by far the most thrilling insight, guaranteed to have wannabe spider-folks glued to their sets, is a report on new technology that allows scientists to transfer genes
from species to species - could this herald a new phase of genetic evolution?
