Nanoparticles deliver 'suicide gene' therapy to pediatric brain tumors growing in mice
Jan 8, 2020 | 15:03 pmResearchers report that a type of biodegradable, lab-engineered nanoparticle they fashioned can successfully deliver a ''suicide gene'' to pediatric brain tumor cells implanted in the brains of mice. The poly(beta-amino ester) nanoparticles, known as PBAEs, were part of a treatment that also used a drug to kill the cells and prolong the test animals' survival.

For CRISPR, tweaking DNA fragments before inserting yields highest efficiency rates yet
Dec 23, 2019 | 18:29 pmResearchers have now achieved the highest reported rates of inserting genes into human cells with the CRISPR-Cas9 gene-editing system, a necessary step for harnessing CRISPR for clinical gene-therapy applications. By chemically tweaking the ends of the DNA to be inserted, the new technique is up to five times more efficient than current approaches.

High-tech method for uniquely targeted gene therapy developed
Dec 13, 2019 | 15:25 pmNeuroscientists have developed new technology that engineers the shell of a virus to deliver gene therapy to the exact cell type in the body that needs to be treated. The researchers believe that the new technology can be likened to dramatically accelerating evolution from millions of years to weeks.

Unique case of disease resistance reveals possible Alzheimer's treatment
Nov 4, 2019 | 17:28 pmDefying the odds, an individual at high risk for early-onset Alzheimer's disease remained dementia-free for many years beyond what was anticipated. A new study led researchers to suggest that a gene variant may be the key, perhaps providing a new direction toward developing a treatment.

New gene therapy for epilepsy provides on-demand release of endogenous substance
Oct 30, 2019 | 16:00 pmScientists have developed a new therapeutic concept for the treatment of temporal lobe epilepsy. It represents a gene therapy capable of suppressing seizures at their site of origin on demand. Having been shown to be effective in an animal model, the new method will now be optimized for clinical use.

Discovery in monkeys could lead to treatment for blindness-causing syndrome
Oct 25, 2019 | 20:53 pmA genetic mutation that leads to a rare, but devastating blindness-causing condition called Bardet-Biedl Syndrome has been discovered in monkeys for the first time. The finding offers a promising way to develop gene and cell therapies that could treat people with the condition, which leads to vision loss, kidney disfunction, extra fingers or toes, and other symptoms.

Deleting a liver enzyme lowers the health risk of sweet treats (at least in mice)
Oct 24, 2019 | 16:58 pmHepatic insulin resistance, caused by diets high in sugar and fat, can lead to type 2 diabetes. Researchers found that the Elovl6 gene plays a key role in hepatic insulin resistance. Deleting Elov6 in liver cells causes a rise in a specific ceramide lipid that protects mice from hepatic insulin resistance due to excessive dietary sugar. The findings could help efforts to find a targeted treatment for the condition.

When added to gene therapy, plant-based compound may enable faster, more effective treatments
Oct 17, 2019 | 22:22 pmToday's standard process for administering gene therapy is expensive and time-consuming -- a result of the many steps required to deliver the healthy genes into the patients' blood stem cells to correct a genetic problem. Scientists believe they have found a way to sidestep some of the current difficulties, resulting in a more efficient gene delivery method that would save money and improve treatment outcomes.

Researchers create new viral vector for improved gene therapy in sickle cell disease
Oct 2, 2019 | 16:28 pmResearchers have developed a new and improved viral vector -- a virus-based vehicle that delivers therapeutic genes -- for use in gene therapy for sickle cell disease. In advanced lab tests using animal models, the new vector was up to 10 times more efficient at incorporating corrective genes into bone marrow stem cells than the conventional vectors currently used, and it had a carrying capacity of up to six times higher, the researchers report.

Researchers advance search for safer, easier way to deliver vision-saving gene therapy
Sep 30, 2019 | 14:23 pmIn experiments with rats, pigs and monkeys, researchers have developed a way to deliver sight-saving gene therapy to the retina. If proved safe and effective in humans, the technique could provide a new, more permanent therapeutic option for patients with common diseases such as wet age-related macular degeneration (AMD), and it could potentially replace defective genes in patients with inherited retinal disease.

Researchers developing new 'DNA stitch' to treat muscular dystrophy
Sep 25, 2019 | 19:36 pmA new therapeutic being tested is showing early promise as a more effective treatment that could help nearly half of patients with Duchenne muscular dystrophy (DMD). The treatment -- a cocktail of DNA-like molecules -- results in dramatic regrowth of a protein called dystrophin, which acts as a support beam to keep muscles strong. The protein is virtually absent in those with DMD.

World's first gene therapy for glycogen storage disease produces remarkable results
Sep 20, 2019 | 18:46 pmThe rare and deadly genetic liver disorder, GSD type Ia, affects children from infancy through adulthood, causing dangerously low blood sugar levels and constant dependence on glucose consumption in the form of cornstarch every few hours for survival. If a cornstarch dose is missed, the disease can lead to seizures and even death. A clinical trial originally set out to simply test the safety and dosage of the gene therapy for three patients with GSD Type Ia. The dramatic improvement in their lives was unexpected.

Tiny bubbles in our body could fight cancer better than chemo
Sep 13, 2019 | 17:13 pmHealthy cells in our body release nano-sized bubbles that transfer genetic material such as DNA and RNA to other cells. It's your DNA that stores the important information necessary for RNA to produce proteins and make sure they act accordingly. These bubbly extracellular vesicles could become mini treatment transporters, carrying a combination of therapeutic drugs and genes that target cancer cells and kill them, according to new research from Michigan State University and Stanford University.
