In
order to reactivate silenced genes, a cell needs to remove certain
“off” markers called methyl groups from the DNA. Scientists have
recently shown that this process involves an intermediate step and an
enzyme that also plays a role in the development of blood cancer. The
finding could lead to new ideas for cancer-fighting therapies.

A
group of University of Illinois researchers have demonstrated that
short spiral-shaped proteins can efficiently deliver DNA segments to
cells. The breakthrough was revisiting a known class of polypeptides and
changing modifying their globular shape.

In
what's being called a landmark study, researchers used gene therapy to
successfully treat six patients with severe hemophilia, a blood-clotting
disorder. The six men each received a single, 20-minute infusion of
healthy genetic material delivered by a virus found in monkeys. Four of
the patients were able to stop conventional blood-clotting treatments
altogether.

Researchers at Yale University have deisgned a new nanoparticle that acts like a virus by introducing a specific gene into diseased cells in order to kill or repair them. The innovation has a number of promising applications in gene therapy.

For the first time, researchers have found a way to inject a precise dose of a gene therapy agent directly into a single living cell without a needle. The technique uses electricity to “shoot” bits of therapeutic biomolecules through a tiny channel and into a cell in a fraction of a second.

Scientists
are reporting the first clear success with a new approach for treating
leukemia. The breakthrough involves turning the patients' own blood
cells into assassins that hunt and destroy their cancer cells.

Cures
for paralysis, blindness and diabetes could all be in reach with
embryonic stem cell research, but the pursuit of medical progress is
being choked by the U.S. rush to secure patents, experts say.

Children inherit about 30 mutated genes from each parent, fewer than had been thought, but enough in at least one case to pass on inherited illnesses, according to a first detailed look at the blueprint for human life in a family. Genomic analysis is proving useful for diagnosing the origins of sometimes mysterious diseases.

Plasmids, which are DNA molecules capable of independent replication in cells, have played an important role in gene technology. Researchers from Uppsala Univ. in Sweden have now demonstrated that plasmid-based methods, which had been limited to single-cell organisms such as bacteria and yeasts, can be extended to mosses, opening the door to applications of a number of powerful techniques in plant research.

It's something like a genetic Band-Aid: Canadian researchers
took donated lungs deemed too damaged to transplant and repaired them with
outside-the-body gene therapy. It will take lots more research to see if the
fix lasts, to find out if the lungs work as well back inside a body as they do
inside a see-through life-support dome in the laboratory. But the study
published Wednesday has lung specialists hopeful they can boost the number of
lungs available for people desperately in need.
