Research shows promise for potential new gene therapy strategy for muscle-wasting diseases

12.03.2008
Investigators in The Research Institute at Nationwide Children’s Hospital have identified the role of a protein that could potentially lead to new clinical treatments to combat musculoskeletal diseases, including Duchenne muscular dystrophy (DMD).

Results of these studies appear in the March 11, 2008 issue of the Proceedings of the National Academy of Sciences.

These studies, led by Brian Kaspar, PhD, a principal investigator in the Center for Gene Therapy at The Research Institute and an assistant professor of Pediatrics at The Ohio State University, focus on a protein called follistatin (FS). Using a single injection, gene-delivery strategy involving FS, investigators treated the hind leg muscles of mice. Results showed increased muscle size and strength, quadruple that of mice treated with proteins other than FS. The muscle enhancements were shown to be well-tolerated for more than two years.

According to Dr. Kaspar, increased muscle mass and strength were also evident when this strategy was tested using a model of DMD. Apart from the injected hind leg muscles, strengthening effects were also shown in the triceps. In addition, fibrosis, abnormal formation of scar tissue and a hallmark of muscular dystrophy, was decreased in FS-treated animals.

“We believe this new FS strategy may be more powerful than other strategies due to its additional effects, including its ability to reduce inflammation,” said Dr. Kaspar.

The strategy showed no negative effects on the heart or reproductive ability of either males or females. The results were also replicated in older animals, suggesting that this strategy could be useful in developing clinical treatments for older DMD patients.

“This research provides evidence of multiple potential treatment applications for muscle diseases including, but not limited to, muscular dystrophy,” said Jerry Mendell, MD, director of the Center for Gene Therapy at The Research Institute, a co-author on the study, and professor of Pediatrics in Neurology and Pathology at The Ohio State University. “These results offer promise for treatment of potentially any muscle-wasting disease, including muscle weakness due to other illnesses, aging, and inflammatory diseases such as polymyositis. Our next step is to pursue clinical trials.”

The Research Institute at Nationwide Children’s Hospital has a patent pending on the FS technique due to the major role it may play for muscular dystrophy treatment and other muscle-wasting diseases.

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
